Title: Using the PedalSync MV-64 Analog BBD Delay Clock chip with your 3205/8 designs
Post by: MoltenVoltage on January 11, 2013, 01:47:39 PM
I'm happy to announce that MV-64 is now available!

The PedalSync MV-64 BBD Delay Clock chip and module output the high-speed digital clock required by classic Panasonic MN3205 and MN3208 Analog Delay ICs and their clones.  MV-64 outputs a clean, variable, high-speed clock designed to drive Bucket Brigade Delay chips, and stores and recalls Delay Time, Delay Ratio, Clock/Tap Status, Modulation Ratio or Rate, Depth, Offset, and Bypass Status.

Here is a link to the datasheet:
http://www.pedalsync.com/documentation/PedalSync_MV-64_BBD_Delay_Controller_Datasheet.pdf (http://www.pedalsync.com/documentation/PedalSync_MV-64_BBD_Delay_Controller_Datasheet.pdf)

   It's important to note that any subset of features can be used, such as only tap tempo and the delay ratios, if you are not interested in programmability, modulation, MIDI, etc.


The goal of this thread is to field technical questions related to incorporating MV-64 into your designs.

There are schematics in the datasheet showing the necessary JFET buffer, and connections to circuits that use MN3102 and CD4047 clocks.

It was a simple matter to make the chip drive BYOC's Analog Delay.  I pulled the 3102 Keith was using as an oscillator and ran the buffered clock into pin 7 of the remaining four 3102's.  That's really all there is to it.  I've also tested it with a 4047 to make sure the clock output was clean and it works great with that chip as well.

Please post your questions here.  Thanks again!

I am very curious about how this works.

I am still fairly new to pedal building. I have several overdrive/distortion/fuzz clones under my belt, but no programming experience and no delay pedals or anything along those lines. And I don't have a ton of money to throw down.

What is needed to make this a full blown delay pedal?
Do I have to have the master controller to build and use this?

Thank you in advance for the response.

Chad,

I applaud your curiosity.  As much stuff as this chip packs in (and it packs in a LOT!), there is a great deal more required to produce a working analog delay.  Enough that it would likely frustrate the novice builder.  My own recommendation would be to hone your chops a bit more with some other projects, and maybe even take a stab at one of the many remarkably simple PT2399-based delay projects floating around (Merlin Blencoe has some terrific ones, and Jon Patton just posted one the other day).  For as many virtues as analog delay CAN have, I have to say that the PT2399 delivers up an amazing amount for very little outlay and few headaches.

Once you've gotten used to building things that fire up right first time, and can manage troubleshooting on your own, THEN take a stab at using William's ingenius chips with some BBDs.

Hi Chad,

Thank you for your interest.

No, you do not need to use the Master Control with MV-64.  You can make a stand-alone delay that has just the features you want, such as tap tempo and modulation.  The MIDI control is optional (but a lot of fun!)

With all due respect Mark, it takes a single wire to convert any BBD delay into a programmable, MIDI-controlled, tap tempo delay with synchronized modulation (or any subset of these features).

I'm in the process of working up a tutorial on how I hacked the Carbon Copy.  Basically remove the delay pot, desolder and lift pins 1 and 2 on the 4047, then run the buffered signal from MV-64 into pin 3 of the 4047.  It's literally a 5 minute hack.

Hacking BYOC's analog delay was even easier.  Simply remove the first socketed 3102 chip and run the buffered signal from MV-64 into pin 6 on the socket (which connects to pin 7 of the remaining 3102's).

As long as the circuits share a common ground, one wire is all that connects them.  Since the Carbon Copy box is full, I put the digital controls into a separate 1590BB stomp box and put a jack where the delay pot went on the CC.  I also used MV-59, the Four Presets chip to store and recall 4 preset settings.

Please let me know if you have other questions.

Thanks again,

- William

If the delay circuit is intact, you are absolutely correct.  My sense of the OP (though I may have read it too superficially) was that he was thinking one might only have to slap on a $5 BBD chip and it was a done deal, not realizing there would need to be buffers, anti-aliasing, mixers, etc.; all the usual stuff a delay includes, apart from the clock section.

If I was incorrect, then my apologies to both of you.

No worries Mark!

It's not clear what the OP wants to do, but in any event, I was able to "pre-hack" the Carbon Copy by looking at some gut shots before it arrived.  If anyone has a BBD delay schematic that uses 3102 or 4047 clock chips, I'd be happy to tell you what needs to be done to hack it and where to connect the buffered MV-64 clock signal.

First, thank you William for sharing your Knowledge and experiences.

I think building a BYOC analog delay is well explained in the pdf instructions, anyway  you can take a look at the videos: http://buildyourownclone.com/advidinstructions.html
I think it´s hard for new builders (like me) but not impossible.

So, just to be ready for the William revelation day ;D, I need to prepare:

-1x analog BBD delay with 3205/8 ic´s (BYOC analog delay, Mxr carbon copy, ) maybe a deluxe memory man?... (it uses mn3008, same terminals assignments  but different supply voltage...)
-1x PedalSync BBD Delay Clock Module (musikding stock? date?)
-1x MV-56B Four Pots Module
-4x Hi-V Pot Modul   
-2x MV-57 Relay Bypass Module ??? I´m not sure about it (sorry, need to study)
-a box, midi conectors, spdt mini switches, bypass footswitch, pots, leds, wire and patience...

Thank you again.

Delaytion will work with any analog delay that uses the Panasonic BBD chips MN3205 and MN3208 and their Cool Audio clones, assuming it is properly modified!  Don't blame me if you fry your delay trying to mod it!

Revelation day has come. Nice. :D. It´s near clear for me.

Time to study....

One question using de mv-64 module.... What is the  input midi clock pin´s in the mv-64 module? 20-21 (label I4-I5)? I suposse they receive the external midi clock signal managed from  6N138 optocoupler and 74F14 Schmitt Trigger... and this clock is sent to the carbon copy by the pin 10 (label14).

Thank you again

Let me one more basic/stupid question... the 6N138 optocoupler and  Schmitt Triggers are soldered in the mv-64 module... isn´t it?

In other words, all I can see in the schematic (except midi jacks) is the mv-64 module?

Sorry again

Hi Pablo,

Yes, the MV-64 module comes with all the MIDI in and out circuitry.

Delaytion is a stripped down project that uses MV-59B (the 4 MIDI Presets chip) to recall Programs 1-4.  Since it's a direct connection, the opto-coupler isn't necessary for Delaytion.  The goal of Delaytion was to make a smaller simpler project for those that don't use an external MIDI controller.

To make an Analog Delay controller that can store and recall 128 programs and sync to MIDI Clock, it's a lot easier to use the MV-64 module, but it will need to be in a bigger enclosure.

Module pins I4 and I5 receive the MIDI Clock and Program Change information, but that data goes to MV-64 (via the opto-coupler and Schmitt Trigger).  The BBD clock output for the Delay comes from pin 14 of MV-64 (labeled 14 on the module) then goes through a JFET buffer to get it up to the right voltage for the Delay.

Post by: Levispeights on March 01, 2013, 03:35:33 PM
First let me say this looks AWESOME and I will be modding my CC and building a Delaytion.

I do have a quick question however. How good does the tapped tempo sync with the actual delay sound?

I only ask because I have build several PT2399 based delays and used the Taptaion chip to add tap tempo, and the problem with that chip is the timing of the delay and the tapped in time doesn't always match up exactly due to the inconsistencies of PT2399 chips.

Is it the same with BBD chips?
Thanks!!!

Hi Levi,

Glad you like it!

That's what's great about the Analog 3205/8 Delay chips, they use a digital clock to set the delay time instead of an analog resistance.

It's kind of ironic that the Digital PT2399 chip can be painfully inaccurate when you use a PIC-controlled resistance since digipots are typically +/- 30% tolerance.  I think that is the likely source of most of your error as opposed to the PT2399.

MV-64's tap timing is accurate to within a 10,000th of a second.

Very promising! Do you think there is way to use something like a 4PDT switch on my MN3205/MN3102 delay to toggle between using the Delaytion and unmodded mode?

Also, is there any stepping when turning the delay time knob?

I think a 3PDT switch would work since you would need to reconnect pins 1, 2, and 3 of the 4047.  Soldering wires to the Carbon Copy's SMT pins would be more than a little challenging!

There isn't any audible stepping that I can hear, although the delay time pot uses 256 increments and the length of delay time (and therefore time between increments) depends on the chip select and delay ratio selected.

Thanks! Sounds good. I'm going to look at my old tokai delay to see if the 3102 is socketed, which would make such a switch easier to implant. If not, there may still be a way :)

OK wait, I just looked at the datasheet and I believe the MV-59 will work, I'll just have to cycle through the presets every time I plug my pedal board in. Right?

Post by: MoltenVoltage on March 08, 2013, 01:51:00 PM
Hi Levi,

Yes, MV-59 will work too.  The only difference is that MV-59 sends the program change message for program 1 on startup, whereas MV-59B does not, it waits until you have pressed the button before sending program 1.

The MV-64 BBD Clock Chip reads the pots on startup, so with MV-59B when you turn it on, Delaytion will read the pots and use that setting, whereas with MV-59 it will recall your first program.

This one is definitely not for beginners! You need to remove 2 SMT parts that are packed tight, and the enclosure is difficult to get apart. That said, it's much brighter and cleaner than the Carbon Copy.

Hi William.

I´m beginning to build a mix version between delaytion and smoke ring delay using my carbon copy. I don´t need all the programable "power" but 4 presets to recall and midi clock is enough for me. I´m going to use MV64 and MV59B modules. Please, let me a few questions:

-I need to connect WR (pin14 mv64 module) to micro-toggle switch (as I can see in the tutorial).... and midi in/out from both modules to the 5 pin DIN jacks... is that correct?

-What´s the connection scheme for chip count select function? Sorry, I can´t find any information about it. In the video, I can see it´s a toggle switch (4 positions?)

-For "Delay ratio select", Do I need to add 2x 1N4148 diodes... Is ,the 4 position switch, a 1P4T?

Thank you very much again.

Pablo

Post by: MoltenVoltage on March 30, 2013, 12:45:09 AM
Hi Pablo,

Sorry for the Delay.   ;)

1) WR is the write switch for MV-64, so yes, that is the one you will use to write programs 1-4.  The other lug of the Write switch will go to ground so when you toggle it closed, then open, the program is written to the current location.

Since you are using MV-59B, you don't need to use a MIDI jack, you can connect MV-59B (pin 2) directly to MV-64 (pin 21) via a 220 ohm series resistor - see the Delaytion schematic:

http://www.pedalsync.com/photos/delaytion/Delaytion_schematic_-_v1.jpg (http://www.pedalsync.com/photos/delaytion/Delaytion_schematic_-_v1.jpg)

If you use 5 volts for MV-59B, use a 330 ohm resistor instead.

2) The chip select table is at page 3 of the MV-64 datasheet.  Which pins you will ground depends on what delay you are controlling.  Which delay are you using?

Chip select is a permanent connection, you will connect neither, one, or both of the CS pins (23 and 24 of MV-64) to ground to make the selection.  No switch is needed.

3) If you want to use all 4 delay ratios, then you will need to use the signal diodes (4148) as shown in the MV-64 schematic at page 11 of the datasheet.  I used a 4 position rotary switch for the Smoke Ring delay, but you could use 2 toggle switches (one for each pin) if you prefer.  Either way you need the diodes for all 4 ratios.

Here again is a link to the MV-64 datasheet:
http://www.pedalsync.com/documentation/PedalSync_MV-64_BBD_Delay_Controller_Datasheet.pdf (http://www.pedalsync.com/documentation/PedalSync_MV-64_BBD_Delay_Controller_Datasheet.pdf)

Let me know if you have other questions.

Thanks again,

- William

Hi William.

I think it´s clear. I was confused because, in the video, I can see you pushing the 1/4 BDD toggle and the led goes green. I supposed it was an option (using BYOC delay).

I use a carbon copy... I will proceed as you say in the delaytion tutorial:

"...Ground the correct pins for chip select (CS1 and CS2 in the Layout Diagram). For the Carbon Copy, ground CS2. For the BYOC Analog Delay, ground both"

Thank you very much again, really.

Best regards.

In the Smoke Rings video, the 1/4 BBD switch actually controls a relay to choose between 1 and 4 BBDs which is already on option on the BYOC delay.  I just automated it with a relay, then used the Four Pots chip to store the status.

Sorry William, I haven´t checked the Byoc delay features  ;)

I´m thinking about adding a CV to the features. I suppose the best way is using a vactrol (led-LDR) and TAP tempo pin...
I can see a "mod switch insert" jack in the prototype... I suppose it´s for bypass the mod features. What´s the best place to add the bypass switch?

I promise you this is the last question... next post will be your child in action :D

Hi Pablo,

On the Smoke Ring delay, the inserts on the back are just 1/4" jacks so you can use a remote momentary footswitch instead of pressing the panel buttons.  There is no control voltage involved, instead the pins are grounded when the switch is pressed.  No need for a vactrol.  You can just run the 1/4" jack in parallel with the existing button, then either will work.

If you want to control the tap tempo with another control signal, you will need to limit it to 3.3 volts.  One easy way is to use your control voltage to drive a 4066 analog switch.

Very cool, nice work. Would be interesting to fuse it with Madbean's DMM clone. Can the MV-64 cop the LFO type that the DMM has?

Glad you like it!  The MV-64 LFO is a sine wave.

Brian at madbean has been experimenting with the chip, but I haven't heard from him lately.

Since the Dirt Bag Deluxe uses a 4047 for the clock chip, the same hack as the Carbon Copy should work.  You'll just need to match the buffer voltage to whatever the dirtbag needs at pin 3 of the 4047.

Hello,


Mv-64 seems very promising!

Is There any hack around deluxe memory man with mn3005 chip to only control tap tempo?
Thanks

Hi William.

Midi clock/tap tempo delay, all mod possibilities, 4 delay ratios, 4 presets to store... I hope.

The beast is in the oven. I hope, next weekend I´ll be enjoying it  ;D ;D ;D

Thank you again, William.

That's awesome Pablo!!

It's a re-housed Carbon Copy, Matthew.

Here's a link to the Carbon Copy mod tutorial (it got moved when we re-did our website, http://www.moltenvoltage.com/ (http://www.moltenvoltage.com/)):

http://www.moltenvoltage.com/pedalsync/MXR_Carbon_Copy_Hack_for_Delaytion_PedalSync_MV-64_Analog_Delay_Control_Station_DIY_Project_by_Molten_Voltage.html (http://www.moltenvoltage.com/pedalsync/MXR_Carbon_Copy_Hack_for_Delaytion_PedalSync_MV-64_Analog_Delay_Control_Station_DIY_Project_by_Molten_Voltage.html)

Pablo went the extra mile and used the MV-64 module which has some features we left off Delaytion.

Delaytion tutorial:

Pablo, with MIDI In, you will have 4 local presets with MV-59, but can store 128 presets using MIDI Program Change messages (MV-59 will recall program 1-4).

Keep us posted!

Hi William. Sorry, I have a doubt.

I´m using Carbon Copy and I need to ground Chip count Select 2.  For this (using the mv64 module), What ground do I need to use?,  Common ground, analog ground? I suppose common ground is correct but I´m not sure.

Thank you in advance

Thanks William. Let me another question ;D.

In order to connect the  mv59 module with the mv64 module for program storage.... I must connect the o5 pin (mv 59 module) with the T1 label (mv64 module pin 24) and I don´t need 220/330 resistor... is that correct?
I´m trying to find the correspondance between mv59 chip pin2 and mv64 chip pin21, using both modules.

Sorry, hope this will be the last question.

Hi Pablo,

Connect the o5 pin of the MV-59 module to the I5 pin of the MV-64 module.  There is already a 330 ohm series resistor on the MV-59 module.

Hi William.

It works and it´s AMAZING!!!!, MAGIC!!! All the settings  stored in each pedalsync master control program... and the amazing carbon copy analog sound... and the infinite modulation possibilities... and the tap tempo for standalone use... in a memory man type enclosure.

Really, it´s fantastic. Thank you very much.  If it´s ok for you, I will try to post a little demo.

Cheers.

Pablo

I have just finished, (With help from William/Moltenvoltage (thanks for that!)),a Delaytion to work with an Aquaboy deluxe with mn3101 and either 2 or 3 mn3005's. It works very well for both and is in fact very easy to do.

So using the mv-64 wih a mn3005 delay is possible.

I posted on how I did set up the delaytion on the Madbean forum some time ago. So here is what I posted.

"I have been correponding with William (Moltenvoltage) who has kindly helped me out setting this up.
So here it is:
At this moment I have the Aquaboy deluxe (MN3101 and 2 MN3005's) and the delaytion boxed up and running for a couple of days.  It is working fine now. I had some problems with voltage regulator of the delaytion getting too hot. You really need a To-220 version of the regulator as the delaytion draws 90-100ma. It still gets hot but that is also because I run the whole combination on 9 volt. The ABDX runs from that on 15 volt with a roadrage. The Delaytion needs to run on 9 volt as the buffer sending the clock to the ABDX needs 9 volt (this is a part of the delaytion). It would be better to run the digital part of the delaytion on 6 volt as that would make the 3.3 volt VR of the digital part not get so hot. I might change that later on, but there is no pads for that on the delaytion pcb so I will have to see how I can do that elegantly. There is room so eventually I will change this.
The clock out from the delaytion goes to pin 7 of the MN3101 and pin 5 and pin 6 should be not connected. I did this by using an extra socket for the mn3101 and cut of pin 5 and pin 6. I then desoldered the resistor going to pin 7 on the ABDX board and solderded the clock out on the pad that was now free of that resistor so it connects straight to pin 7.
The clock of the delaytion controls the mn3101 now and that means that the whole modulation part of the ABDX is not working.
I have experimented quite a bit and decided that that is the best working option for me. The modulation on the delaytion sounds great and is programmed in the delaytion presets.
I etched my pcb from the delaytion documentation. I think it would be worth getting the fabbed board. There is quite a lot of jumper wires and of board wiring with the one-sided etch. The fabbed pcb is much cleaner.
The clock is now slower then I had the clock running on the original ABDX build. Delay time is even longer but there is also some clock whine coming in then.
I had the ABDX also running on 3 MN3005's before I started with the Delaytion. That worked fine although much darker.
It works with the Delaytion also. You have to set the chip select different then.
For now I have decided that the two MN3005's works fine.
If I will switch to three MN3005's then I would also put in a switch to switch to two MN3005's. In that case the switch will also have to switch the chip.
Hope this helps."

I used a board that I etched from the layout that is part of he Delaytion docs. It is a nice board but, as it is single sided, has quite a lot of jumpers. Next time I would order the fabbed board. There is already enough of board wiring without those jumpers..  ;)

Some of the parts might be hard to find, so I've put together a kit with the internal parts for Delaytion plus an extra RCA jack for the modified delay:

Hey William,
Are you guys still selling the Delaytion kit? The site has been moved, where can I find it at? Thanks!!

Hey there.  I am working on using the MV-64 as just a tap tempo for the MXR Carbon Copy.  I have modded the Carbon Copy as per the instructions on the Molten Voltage website.  For the MV_64 chip, I have breaboarded the following layout, based on the schematics provided on the Molten Voltage website. (http://i18.photobucket.com/albums/b145/jrallman/SCAN0015.jpg)
I am having two problems at the moment and was wondering if anyone could assist.  First, the rate LED blinks and I can change the rate of the blink using the tap tempo switch, but can can't make it slow down as much as I should be able to.  Seems the lowest is somewhere around 140bpm or so.  Second, it doesnt work.  What I mean by that is, I hook it into the modded Carbon Copy and there is no effect.  The Carbon Copy sounds the same whether the effect is on or bypassed.  No delay at all, and yes, I have made sure the controls were moved to all different positions as well.  Thank you all for any assistance.

Hi first of all thanks for all the great info you guys provided
I have a question , I have two malekko ekko 616 mk ii  pedals and I would like to mod one using the the delaytion thatI'm currently working on
And the other I would like to just add a simple external tap tempo . About
Setting up the malekko ekko with just the simple external tap tempo
What needs to be done . What parts do you guys think I need and where do I plug
Them . Would you shine some light on my project thanks

Hi,

I finished my delaytion (mv-64 and mv-59) and observed a strange behaviour.

All functions work properly, but when the preset is at the first position (LED off) the lowest clock frequency is 35 kHz (Delay pot at minimum). When I increase the speed of the clock it goes up to 200 kHz (at 0.16v at pin 2) and jumps back to 70 kHz at 0V, pin 2).

If I change the delay ratio switch from the 1:1 position to a different one, i.e., ground either pin 6 or 9, and switch it back the clock drops to around 12 kHz, which is what I see at the lowest setting for the other presets.

I am not sure why this happens, but it always happens when I'm at the first preset.

I would also be interested in the voltages at the pins of the MV-64, since the CPU pin (pin 20) is only at 2.58 V.
The other pins are either at 3.33 V when connected to the 3.33 rail. Pin 6, 9 and 11 are either at 2.94 V or at 2.57 V, but it slowly changes. It looks strange, since there is no cap connected to those pins, that would create the slow build up in voltage and the drop to 2.57V. It seems, that it does not affect the operation (except at preset 1 anyway).

Anyone experienced something similar?

Post by: thomasha on December 01, 2021, 01:14:55 PM
So, trying to fix this I though about adding a way of shortly grounding pin 6 when the presets are changed.

My first instinct was to tie pin 6 to the presets pin, but that fails when pin 6 is grounded by the switch.
1- With the presets pin always grounded it will either not change the preset when the footswitch is activated or change it continuously. I haven't tried it, but already identified some problems.

My second guess is to use a diode to overcome the problem above. Pin 6 would only be low when the presets pin is low. With pin 6 low the diode would not conduct. But then, there is the 0.6V difference. I have to test this one.

A more appropriate solution would probably be using a transistor to switch pin 6 to ground when the presets are changed. Now I am not sure, if the longest delay of the tap function is also affected. It seems I cannot tap slower than a certain value that produces a clock signal of 20 kHz (btw, I am using 2 MN3005 with the 4047 chip, so pin 23 is high and pin 24 is low, the lowest clock frequency of the delaytion is about 12 kHz).

Any suggestions on this one?
