Hi dean sounds like amazing news 
Looking forward to see the V2 progress. Will keep an eye here and your blog to test the processing GUI or any guide to incorporate those lovely Encoders and LCD to the Sidaster!!
I think there might be an issue with MIDI, I definitely get a sound when pressing the a5 button. Also can see the Midi interface responging correctly, and I managed to switch on and off an led with Midi so that part is correct.
My other issue is the Power supply I think, I got my SIDs from two commodore 64 shiped from America, and had 110v supply which I can´t use here in Spain. So Im using different 12 V transformers for the 6581 with more or less same performance.
Will keep trying things and will let you know.
Keep up the good work!
Cheers,
Julian
