Yocto 1.0 won/t play, multiple pattern select buttons light
Posted: Dec 17th, '17, 22:20
Ok, so the story goes last year all of a sudden my Yocto started playing the cowbell on every step, I eventually got that corrected and then all of a sudden it started acting like the shift button was permanently stuck on. That was traced down do a dead shift register IC 7 thanks to help from you guys, after that it more or less worked well, but I couldn't use it in expander mode as a module, it would trigger a few sounds but it did not behave the way it is supposed to. That led me to now: I am pulling all of the original shift registers, socketing them, and replacing with new figuring that if the one went bad earlier another one may be responsible for the MIDI weirdness. Well, I've just replaced ICs 2 and 3, and after turning it on to test, now it will not play at all, multiple pattern select buttons can be lit at once, I cannot use init mode... it's totally crippled. I've tried several of each chip, I can't see any shorts, I've reflowed everything... this makes no sense to me
Does anyone have any suggestions? The digital part of this thing has been super buggy since I finished it, it has never worked reliably for long, so if anyone has any insight I'd love to hear it. I'm quite frustrated.
Thanks
