8. MIDI

8. MIDI-CPU

Musical Instrument Digital Interface is embedded in the system in the form of MIDI stops and MIDI volume.  These options, required to be wired to Stops1 Input card address assignment, have to be assigned and captured in this routine.

The Stops Mask Assignment is a group capture or snapshot (subset) of the 64 input pins assigned to Stops1 that are wired to MIDI stops.

The MIDI Volume is again this idea of a group capture or snapshot (subset) of the 64 input pins assigned to  Stops1, group captured in every incremental contact roller position, that is, from no contacts made incrementing to all contacts made.

Enter the Power Up Programming Sequence as instructed in Power Up Programming Overview.  ‘Increment’ with key 3 to 8. MIDI and ‘enter’ with key 8.  The LCD will display “MIDI Setup”  “Stops Mask”.

Use key 3 to choose either Stops Mask or Volume and enter with key 8.If Stops Mask, then the LCD will display a line for what has been stored in memory and an active line for what stop actions are physically on.  This is done with a number for the total number of pins followed by a S1-xx number which indicates the lowest pin number of this mask assignment subset of Stops1(S1).  To capture the MIDI stops mask assignment, physically turn on all MIDI stops at the same time.  You will see the total number on followed by the S1-xx.  To see all of the xx pin numbers that are part of this active total, use key 5.  ‘Enter’ the active stops into memory by using key 8, this changes the memory line to look exactly like the active line.  To see or verify all of the xx pin numbers that are part of this memory total, use key 3.  When the memory line reads exactly as the active line, exit or escape with key 1.

If Volume, then the LCD will display the choice of AtoD, Swell box roller, or Disable(d).  If you are not using the MIDI volume feature, this must say or be disabled.  Choose with key 3 and enter with key 8.  If AtoD or Disable , then the LCD will proceed to 9. C.A. Fields.  If Swell Box Roller, then the LCD will display the memory and active lines to be used for the total number of contacts on the roller.  Engage all contacts in the full open position and ‘enter’ with key 8, this changes the memory line to look exactly like the active line.  Then select key 6 to proceed to the individual stages of the swell box roller, beginning with stage 1, and with repeated hits of key 6, incrementing to the number of contacts + 1.  At each stage number, activate the contacts desired to be on and ‘enter’ into memory with key 8.  At any time keys 3 and 5 can be used to display the pin numbers that make up the total on.  When completed for all stages, exit or escape with key 1.
