Hi Stefan

I've built the Drum, Delay and VCA modules over the last few months and they are all great. However, the Pyxis won't work. I soldered the crystal on the wrong way round so I changed that and the STM chip is a bit messy but the rest of the soldering looks ok. The lights come on but no sound.

I realise it is discontinued (I bought it for a discount on Pusherman) but what do you think? Would sending me the schematics help?

Any ideas welcome.

Thanks.

Hi there!

I am building the sum v2 at the moment, but I cannot find the pot meters for the pan levels.

Thonk does not stock them..

Mouser I can’t find them..

Any alternatives or should I just settle for the non detent ones?

Hey Stefan,

Just a FYI about a couple of mistakes.

• The BOM has the incorrect link for the 10K V/OFST trimmer.

• The iBom has the incorrect value for R32. Should be 220K not 100K

Regards.

I have built two push modules, one works correctly, the 2nd won't increment with a button push. The reset works correctly as when I power it on the starting step is somewhat random and pressing reset returns it to step one.

If I jump from pin one of the cd4024 to either of the upper pins on the switch the switch glows dully and the step increments / cycles. When i press the switch it does glow and I do not believe the switch is at fault. What is the signal path from the switch to pin 1 on the CD4024? I havn't been able to beep it out with my multimeter.
