Hi all,   Please go easy on me, I am new to MIDI and Sammich!   I have built a Sammich a few months ago now, and was having problems flashing it, Rowan kindly had a look at it and between him and TK it was fixed (bad optocoupler)   Rowan flashed the MIOS and patches for me and I replaced the opto coupler, and bought 2 new SID's as the existing ones were both slightly faulty, now its up and running and the Sammich sounds great triggering the patches from the buttons on it's front panel.
