Re: Yocto 2 makes only 1 bass drum sound on startup in test
The promissed update: The CD4049 was replaced by one ordered from Conrad, and that solved the problem. Now all the voices that are allready built trigger happily in Test mode. The outputs of the 4049 now toggle between 4v and 15v instead of 9v and 15v, probaply good enough to get the 4051's to do th...

Re: Yocto 2 makes only 1 bass drum sound on startup in test
Currently, only the parts needed to trigger voices in test mode are installed. And by looking at the schematic, that's indeed all you need to trigger voices in test mode. The rest is basically just shift-registers for controlling the Led's and switches. But I'll build that soon. I did try forcing a ...

Re: Yocto 2 makes only 1 bass drum sound on startup in test
A small follow-up after some more elaborate measuring: Triggers from Trig-shift registers (IC 112 & 113) are working giving nice 5v 1ms triggers. DAC seems to work, giving 13V at the output of the DAC buffer (IC6). But this 13V is not getting through the multiplexers (IC 11 & 114). Data is g...

Yocto 2 makes only 1 bass drum sound on startup in test mode
Hi there, In the process of building the Yocto 2, I've finiched PSU, IO board, PSU busses, Noise, Kick Drum and sequencer parts needed for test mode. Now when I switch it on, only 1 kick drum sounds on startup, and then remains silent. I've been probing araound a bit and found the trigger outputs (I...
