score one hen's tooth!!! maestro r&s

Love this! Even a super scaled-down version of this would be sweet. I imagine the filtering is familiar but that drum triggering/looping is making me drool. Hilarious, perfect for live shows. I have a Synsonics drum machine from 1980ish that has a giant DIP chip that basically does everything. I'd love to find a CMOS or discreet way to do something like this, even if it's pointless, meaningless, inefficient, etc. Maybe a ground-up design would be more realistic...

Maestro's sense of style is badass. Those colors and fonts are friggin' awesome.

of course - dunno how much the community would be interested in a gadget that allows you to play would be 70s "electronic percussion" sounds from guitar

That's a joke, right?

haha, well, I have to say that the Maestro "drum" sounds really sound about as far away from drums as you can get. The sounds are all based on white noise filtered differently. I have a Maestro Rhyhm King - a standalone drum machine that has some similar "drum sound" circuitry. Interesting thing about that is that you can run audio THROUGH the drum machine and the logic-based sequencer provides some filtered rhythmic gating effects - like a tremelo with preset patterns and a little modulated lowpass...But the drum sounds are basically the same as what you can hear on those old cheezy organs you find at garage sales.

The Rhythm and Sound circuit must trigger the white noise blasts with some kind of envelope/amplitude detector so when you play on the guitar if it hits a certain level then the "drum" sound is triggered...

I don't doubt that people here will embrace it but be prepared...Maestro Rhythm is an "acquired taste!"

PS Maestro Rhythm King is the drum machine you hear on all the killer Sly & the Family Stone tunes...Family Affair etc.

it actually doesn't sound bad. not RIGHT, but not bad.

[garcho]

I wonder if it's similar to some of those Thomas Henry designs?

[Strategy]

Maestro stuff is way more primitive sounding, but yeah, not "worse" sounding or "wrong" the TH stuff is closer in a way to later Roland, Simmons etc. and in many ways, more complex in terms of sound - check out the TH Mega Percussion Synthesizer PCB you can get through the electro-music.com forum.

The Maestro things sound similar to the Roland CR-78 which was like a rudimentary predecessor to the TR series...

More primitive = more fun to mess with on the breadboard.  )

Just picked up one of these at an out-of-business organ store and the functions seem to be working but the output is extremely low, I have to use all the gain available on my Overstayer Ampeq-02 DI input and it's still very quiet. I'm assuming there's a transistor that is blown or electrolytic cap that has gone bad in the output mix section. I can't seem to find the G1 schematic posted anywhere except a "pay me $20 for a PDF" site, did it ever get uploaded here?
I'm new to the site, so apologies if I'm not looking in the right place.
Thanks!

(EDIT: just found the "Schematics" link above but don't see it there)
