My project is to midify a 3-manual TO console which began its life as an Artisan Oriental model in 1969. Despite its age, the unit is in pristine condition with pipe organ appointments throughout, wooden key desk, and a most substantial 32-note AGO pedalboard. The completed project will consist of the following: Solo manual ~ 61 notes Great manual ~ 61 notes Accomp manual ~ 61 notes with second touch Pedal ~ 32 notes with second touch 158 Reisner SAM stop controls Main/Solo swell shoes Crescendo 10 dedicated pistons per manual 18 General pistons 1 General cancel (velocity control is not desired; second touch derived from contacts) I may opt for direct keying rather than scanmatrix to lessen potential latency as I do not know how much the PC relay will introduce on its own. Having laid out the basic recipe, what does the collective braintrust recommend in terms of the number of MBHP Cores and MIDIO128's to achieve MIDI communication with the PC? I do understand that SAM magnet controls is a different beast altogether but have a rudimentary understanding how MIDIO128's handle this with respect to keying electro/mechanical devices through MIDI-out from the PC Relay. One final question ~ does Smash provide the 128 Kits ~ I did not find it listed on his website (or I don't know where to look) but did find the MBHP Core kit listed. I have read....and read....and read....(and am still reading) the forum for clues and completed designs on previous projects of this type. My forte' is not programming but I can build anything electronic that sports good schematics. Therefore, I'd like to begin construction of the modules as I broaden my knowledge base through the forum and individual member contact from time to time. Any comments, directions, or suggestions will be welcomed.
