Midi Channel 9 (offset 0)

'-------------------------------------------------------------
PIC1: Motor, register and lights control:

Motor: The midi mapping is on volume controller (7). We have a single phase motor switched by a zero cross triac solid state relay.
So we use 1 bit as 100Hz slow PWM controll:
midi volume 0 = BIT = 0, permanent OFF
midi volume 1 = 1 pulse ON, 99 pulses OFF
midi volume 20 = 20 pulses ON, 80 pulses OFF
midi volume 50 = 50 pulses ON, 50 pulses OFF (0.5s ON, 0.5s OFF)
midi volume >= 100 = BIT permanent ON

[kode voorbeeld: motor Ake, maar daar werkt het met controller 1].
[nota: de motor is eigenlijk een 3-fazen motor en zou dus ook via een PIC gegenereerde 3-fazenstroom
kunnen geregeld worden, of via een standaard industriele motorcontroller, waarbij de PIC dan 0-10V moet opwekken.]

Registers:
midi mapping on program change command: (range: 0-15 other prog.changes reserved for selection of velo-scalings, progs. 122-127)

bit 0 => register 0 ON/OFF bit
bit 1 => register 1 ON/OFF bit
bit 2 => register 2 ON/OFF bit
bit 3 => register 3 ON/OFF bit
bits 4-7 must be %False

PIC's 2 tot 8: player piano design boards (version 1).

PIC2: Note ON/OFF + velo for notes: 29-38
PIC3: Note ON/OFF + velo for notes: 39-48
PIC4: Note ON/OFF + velo for notes: 49-58
PIC5: Note ON/OFF + velo for notes: 59-68
PIC6: Note ON/OFF + velo for notes: 69-78
PIC7: Note ON/OFF + velo for notes: 79-88
PIC8: Note ON/OFF + velo for notes: 89-98
                                    note 90: bell: pulse only - no hold 
                                    notes 91-98  : hold only (lights) 

Velocity default pulse range: 0.5 - 60ms
Bell:
midi mapping on Note 90. With velocity. Pulse only, NO hold. (Hold will burn the solenoid!)
pulse duration range: 1 to 30ms.

Lights:
midi mapping on NOTE ON/NOTE OFF for notes 91-98.
