MS-plus - Midi Control of system/patch/effect parameters

[mungewell]

Quick check of MS-plus to ensure we can access the effect/patch parameters in the same way. Patch with single EQ effect, parameters set in a 'wave'.

Control seems to be using a different '0x64 0x20' command.

First turn on editor mode, turn off effect, turn on effect in slot 0.

$ amidi -p hw:2,0,0 -S 'F0 52 00 6e 50 F7'
$ amidi -p hw:2,0,0 -S 'f0 52 00 6e 64 20 00 00 00 00 00 00 00 00 f7'
$ amidi -p hw:2,0,0 -S 'f0 52 00 6e 64 20 00 00 00 01 00 00 00 00 f7'
                                                   ^^ 0=Off, 1=On
                                                ^^ Item 0 = Effect Enable
                                             ^^ Slot 0

[mungewell]

First turn on editor mode, set lowest value in First Parameter

$ amidi -p hw:2,0,0 -S 'F0 52 00 6e 50 F7'
$ amidi -p hw:2,0,0 -S 'f0 52 00 6e 64 20 00 00 02 00 00 00 00 00 f7'
                                                   ^^ 0=Lowest Value = -12dB for BassEQ
                                                ^^ Item 02 = First Parameter
                                             ^^ Slot 0

Note: Effect parameters are 'Item 02' for left most, through to 'Item 09' for the right most ('vol' for BassEq).

Note: 'Item 01' is effect type and requires 32bit value to be split into 5 7-bit values

Changing patch Name

                                                 ^^ 20 = ASCII code, ie space
                                              ^^ 00 = First Character, through 1B last

Changing 'R Position' (where in the effects chain that the R output is fed from) - This may only work for the MS-60B+

                                                ^^ 04 = R Pos
                                             ^^ 64 = System Setting

This appears to be patch volume, but it's not controllable via the UI on the pedal

Changes the PPRMv2 block we (/I) have been too lazy to decode

    PPRM = Container:

[shooking]

A new midi mapping for later pedals? Maybe to fix some of the inconsistencies on the "*Four" implementation?

[mungewell]

@shooking Side question; did you/'we' ever figure out how to remote control the drum machine. See #85
