Hallo,
Ik heb een x0xb0x gebouwd. het analoge gedeelte lijkt in orde, maar de sequencer doet raar.
Ik heb er al een hoop tijd in gestoken, maar loop vast in de mogelijkheden.
Hieronder in het engels (vanwege copy paste) mijn situatie,
Als iemand de problemen herkend, of wil helpen, nou dan graag!
I've build my x0xb0x, checked the VCO and VCF, and checked all the polarities, and IC's. Power is fine, there are no shorts, and there is no trash. I looked over the board several times. The wire connectors(IO and main board) are also fine.
But the problem:
-when i power up, all the lights go on, but there is no sound or interaction possible. When I power of and on again within a few second, a section of the led lights is off. After a few of these reboots, all leds are off.
When i try to connect with the CPU with USB/conbox, the CPU isn't there.
I bought a new CPU, with sokkOS 1.9.1 on it, so that should be fine (first CPU had no bootloader).
I checked the analog voltages, but havent checked the digital section, because I haven't got them(reference).
I spent a lot of time measuring and looking for errors, but didn't find the error.
My hope is running low. But I won't give up. This monster will work!
Does anyone recognize this problem?

Als je met reference bedoelt dat je geen juiste aarde weet dan kun je gewoon de analoge GND gebruiken. Je zit er dan misschien een tiental mV's naast maar dat zou niet erg moeten zijn.
9V zou het einde zijn geweest van je uC. Het had wel verklaard waarom je sequencer zo raar doet
