Hi Everyone,
First, I want to thank Wilba again for this amazing project. This is my first post just wanted to say hi and ask for some help with my sammich. I soldered everything and loaded the midibox application, but the sids only play very muffled sounds. All the voices respond, they are quiet, the pitches are all the same and the noise floor is quite high. Also, the encoder does not respond and the shift button introduces more noise when pressed. The up and down buttons do not seem to work as well. The voltages all checked out except for the 12V rail which was only 11V. Maybe this is the issue? Do any of you midi masters have any suggestions?
