Program Change Nr. Selection of requested MIDI Program for definition.
Accept Program Selected Pgm Nr. can be accepted or ignoreg when that number is received from MIDI. If the Pgm Nr. is ignored, no changes will occur after that program number is received. In this case, all other parameters have no signification.
Clock Source The parameter selects source of clock for internal sequencer of TR-808. If "MIDI Clk" is selected, tempo of TR-808's sequencer is derived from MIDI clock. For "Internal Clk", the sequencer is driven by internal tempo generator of TR-808. If "None" is selected, internal sequencer of TR-808 is turned off - it can't be started anyway. *).
Instrument Source The parameter selects which method is used for triggering of TR-808's sound generators. They can be triggered by acceptable Note On MIDI commands only (parameter = "MIDI") or by internal sequencer of TR-808 only (parameter = "Sequencer") or by both ways simultaneously (parameter = "MIDI + Seq."). If "None" is selected, TR-808's sound generators can't be started anyway. *).
Transport Control The parameter selects control source for START / STOP functions of TR-808's sequencer. For "MIDI" value of the parameter, START / STOP functions are controlled by Start / Continue / Stop MIDI commands only. For "Str/Stp Button" value, START / STOP functions of TR-808's sequencer are controlled by START/STOP button on TR-808's panel only. For "MIDI + Button" value, START / STOP functions are controlled by MIDI commands and START/STOP button simultaneously. *).
Note *) : There is only 14 valid combinations of three previous parameters setting:
