Nice! I’m interested (and it’s good to see you’ve explored the Ambika as well).
Cheers

Of course

Gene really seems like an awesome and original machine. It’s the power section that scares me. I would actually have preferred a wall wart.

Interesting! I appreciate the effort.
Cheers

The price for the Virtual CZ was just increased 72 Euro's. Ouch.

I’d just like to add that there are still tons of useful information and guides related to Shruthi/Ambika/Anushri on the legacy Mutable Instrument pages for discontinued products:

Wow,

all of the above sounds great! Any reason for going with 6n138 instead of 6n137?
Edit: the reason I’m asking is that I’ve seen several recommendations for 6n137 over 6n138, e.g. https://forum.mutable-instruments.net/t ... plers/5255

Happy (better) new year

Yes, this looks fantastic! Happy new year!

Agreed. In this case the required patching is so minimal that a small chiclet adapter that plug into the 4n35 together with bridging/removal of the then unnecessary R1/R17 resistors will work a charm (but it will add a little height). The good thing is that the majority of the existing pcb wiring fo...

Yeah I meant a small adapter, like a midi in chiclet.

Below are some excerpts of the Opera Rotas current use of 4n35 vs common use of 6n137 optocoupler. As I proposed, a small adapter and some hardware patching would be needed to re-assign pins and some of the output circuitry, but I guess it should be manageable using a small protoboard. Then of cours...

That's what I'm referring to as hardware patching. That part is not hard to do. B If I'm not mistaken (I may very well be) it could be feasible to replace the 4n35 with the more commonly used 6n137 optocoupler. This would of course take some hardware patching, but it would not have to be a completel...

Hola! If I'm not mistaken (I may very well be) it could be feasible to replace the 4n35 with the more commonly used 6n137 optocoupler. This would of course take some hardware patching, but it would not have to be a completely separate board (more of an adapter), right? I'm sure I will enjoy the Oper...

Thanks, I totally understand. I was mostly curious about the tweaking capabilities (e.g. bass drum and clap) compared to the stock dr-110 sound. Cheers Any chance of a demo? Cheers I’ve got a track finished up utilizing the prototype of this module where I’m manipulating the kick pitch and it makes ...

Any chance of a demo? Cheers I’ve got a track finished up utilizing the prototype of this module where I’m manipulating the kick pitch and it makes a world of difference. Also the spread function on the clap is just fantastic. It really opens up the prospect of church claps and similar sounds. This ...

MIDI will be great even if it's done via a separate board.
Cheers

An option mat be to use the Highly Liquid UMR2 board. From what I know it was originally designed for this kind of task but I guess it’s somewhat old, unsupported and poorly documented by now.

Interested in presoldered SMD.
(I bought 5U 606 PCB’s from JanneI previously and they are absolutely beautiful in quality and layout.)
Cheers

+1 for Hal Chamberlin ”Musical Applications of Microprocessors” and Mutable Instrument source code!

Hi,

I just noticed that 4250 is also available from electrokit.com (Sweden) and Banzai music (Germany) and I'm sure many more...

Cheers

Hi,

An alternative might be to go with the original Polivoks chips and some modifications of resistor values as mentioned in https://mutable-instruments.net/archive ... /polivoks/ (not sure about what does values should be though).

Ericasynth sells k140ud12 (corresponding to UA776).

Cheers

Thanks,
do you plan to provide schematics for those that buy PCB’s (in case I want to try to figure it out for myself)?
Cheers

Indeed, I always do!

Nice! This surely looks like an instense but great build. I wonder if/how feasible it would be to skip the controller pcb and replace it with only sound modification pots and midi trigger inputs for non-euro usage - is the routing between PCB’s clearly defined? Apologies if this doesn’t make any se...
