Can someone clarify for me. What can/can't this version of the midibox sid do? What about patch storage? I have been using a C64 with MSSIAH and dual SIDs and like the 6 note poly, 3 note/3 track or 6 track modes but don't like having to have a monitor. I've been wanting to build a midibox for ages and this one sounds like the push I've been needing. If it would have had a filter option my head would have exploded. :o
