some trigger sources can't trigger Karp / DU-KRPLS module.
to fix, simply clip off this resistor on the core pcb (bottom pcb).
trig led won't work after this but it is not needed.
Then new Karp / DU-KRPLS core circuit provides a better, louder outputs. We'll provide free assembled core PCB to owners, please email me with your proof of purchase (emails that did the purchase, or a picture with your email on a paper with your module, etc), shipping will be 10$ airmail. Or purchase from shop and let me know in the comments.
Below is the method of replacing core board.
Yesterday I've seen a great way to use Voltage Memory module, utilizing all banks, pages and outputs, to set up a variaty of scales and pitch layouts.
We can see it's not only great for manual triggering, but also equally nice for generation with multiple sequencing modes - a supreme touch keyboard for melodies and harmonies.
And once set, it doesn't need to be reprogrammed, yet still providing as much variaties as any music keyboard with the advantage of deep customization. I remember Tony from Make Noise told me about meaningless obsession for modular over-repatching - indeed, as musicians we can customize musical tools over time, and it doesn't need to be redo too often, right?
It's inspiring, so click the button below to have a look :
