just wanted to bump this and ask Fonik or anyone else how they set the offset trimmers?

thanks!

thanks for the bump, i totally missed that.

i think this has been asked quite a few times int he past, and i should have added something to the documentation...

anyways, i set the trimmer so that the LEDs are only just not lit.

another approach would be to set the trimmers according to the internal LFO, so that you get the nicest sweep/range.

BTW on my current prototype for the upcoming fonitronik eurorack module i lowered the input resistors for the external CV and the trimmers to 100k (!) to get more control. this is running with 12V though, and i have attenuators on the CV inputs...

Got my build done today and it works great! Setting the trimmers is still a little funky depending on where the freq pots are at, but ill mess around with it a bit more. Just a heads up, JP7 has v+ and v- switched on the silkscreen. Luckily I checked with my continuity tester before I hooked it up to the power supply Smile

Thanks again matthias! Let me know if you want to share some of the upgrades hehe

Also, I did the timing cap mod and while I get great variation between the cap selection, there is very little variation on either extreme of the rate pot. Is this normal?

Has anyone made Eurorack panels for these?

I have a spare unpopulated board ready for action if someone can offer me a panel to buy Smile
