Sounds really cool. Looking forward to the updated schem, not that I'll understand it all.

Looking forward to the updated schem,

Will try to put it together this weekend...

I think I should draw it a bit less confusing..... ;)

Here's an updated schem including the LED/LDR gain control, programmable divider and sine generator.
I hope it's not too confusing....

That's quite a schem you have there...impressive.

Greetings from sunny Mar del Plata, Argentina!! That looks a very interesting circuit.

Here's nother update for the schem:

http://www.aronnelson.com/DIYFiles/up/Harmonic_Ring_Modulator_current_sch_15-04-07.pdf

Still missing: a two-band tone control. Any suggestions would be highly appreciated  :)

Next steps will be to make sine and sqaure wave blendable so you can have everything from pure sine to square wave as a carrier. Also a distortion stage a la Ring Stinger for the dry signal as well as some blend pots for mixing dry, ring mod, and maybe distorted guitar signal still have to be done......

I was already thinking about which controls might be useful with expression pedal and what other outputs to add as jacks (e.g. the AMS100 pluck detector ouput). Any ideas?

Will try to do some soundsamples for the sine octaves in combination with the RingMod next week.....


Regards,

Markus

Although I'm utterly intimidated by the complexity of the schem (I'm just an amateur, amateur I tells ya!!!) I vote for Baxandall tone control, popularized by SansAMP, and seen i nthe schematic by Tonepad.com:  http://www.tonepad.com/project.asp?id=22

Hi M,
for a tone control-- i'd go 4 a PAIA 4730
it's a voltage controlled multimode filter..LowPass BandPass & HighPass.
all available at same time.!.  U can combine the HP & LP and make a NotchFilter also   ;)
Sine waves have nothing to filter, but the SQuare waves certainly do.

As for pedal controls---
changing the fuzz changes the timbre of the RingModulation.
Since your carrier, now, is an octave multiple of the fundamental,
using a VoltageControlledFilter (VCF) will allow control via a pedal.   ;)
So,....how about another 4730 here(??)  --after the fuzz...

Since U have most of the circuit(s) for an envelope follower, using an EF to "gate" the RingModulation
or the fuzz, might be interesting....(?)
Kind of like a hybrid of a Meatball-meets-RingO-thru-a-Filter-thingie...

I like the word "thingie" ......verrrrrry "technical".

How big did U say the pcb was going to be????    LOL!!!

I forgot to say I need a "simple" two band tone control  ;)

Thanks for your vote  :icon_biggrin: This one gets my vote too :)

The 4730 is too complex for my purpose. I want to finish that thingy soon. So additional modules will have to wait  ;)
Nevertheless, thanks a lot for your help toneman!!

The voltage controlled low pass (LM13700) works fine for getting a rather pure sine wave. I just need a "post-ring-mod" tone control... :)

Considering that the PCB will be pretty large with the circuit in it's present form I fear I have to skip additional " Meatball-meets-RingO-thru-a-Filter-thingie..." modules  ;)

Impressive project and realization.
I think I'll have to go through all that once or two times more.
Pretty thick indeed.

Sounds really good to me

thank you all

Glad you like it  :)

I think it would help if I made a summary on how the circuit works, or at least I think how it works  ;)

Obviously it would... as far as I'm concerned . I did not went through my second reading yet so I'm still stuck in the maze of those trigs PLL VCO S&H  ??? but I know I 'll make it(Wonderfull hope of the noob  ;) )

can anyone here help me understand this schematic? the lf398 doesnt make much sense to me (the pins are what?) and there is no input processing shown. is there a good low pass filter schematic i could put in front of this project?

any 4046 experts out there? (thats the main section i am interested in is the 4046 and diviiding part

thanks!!!
