Re: OPERA ROTAS, a DIY mutant drum machine BUILD THREAD

Just finished building mine, it sounds great.

just a warning to others - Don't push the random button if you are using headphones, the volume is seriously unpredictable. (Probably worth running the output into a limiter if you plan on experimenting with the random mode)

Hi everyone, just testing and tuning my kit. Can someone please confirm whether the VCA should completely close when no gate is applied? Mine seems to have a continuous low level bleed. Thanks

Hi I'm after a bit of advice. My midi still isn't working properly, my keyboard triggers the same note on every key. I don't have much experience with atmega or any digital circuits, but it seems that the crystal isn't oscillating (no reading with frequency counter at pins 9 or 10) I've replaced th...

Hi has anyone got midi working correctly? I've finished my build and everything sounds great using an analogue sequencer, but when I try to use a midi keybord I'm only getting gate (no cv). I suspect a dodgy 4922 as I get 0v at pin 10 and pin 14 when sending midi in, but just want to check if this i...

Thanks for your replies. I've not added additional filter caps, looks like I need to search this thread to find out more about that. It hadn't occurred to me that the issue could be with the input, I just assumed it was the switch. I've not calibrated the VCOs yet as I don't have a reliable cv sourc...

Electronic Switch

Hi, I'm finally putting the finishing touches to my TTSH, this thread has been invaluable to me during the build. I have noticed some strange behaviour from the electronic switch. If I patch an audio signal to c and then patch a and b to the right and left speakers I get the expected ping-pong effec...
