Title: how to map 2 events to other events
Post by bibmidi on Sep 14^th, 2018, 4:57pm

I want to map GM2 patch list to selected patches of my Synth, but only GM2 patches with LSB=0.

how to make folowing:
If
LSB=0 And PC=0
Then
MSB=87 And LSB=64 And PC=0
====================

and so 128 times for PC=(0.....127)

Hi

You only want a altered bank change message when CC32 = 0
Using CC32 = 0 (LSB) as the trigger to change the bank...

Create a Data Map with 2 lines

The first line causes CC0 87 to be output - select "Clone"
Channel x: Event=Ctrl : Ctrl# = 32, 32 : Amount= 0, 0
Channel= Match input : Event=Ctrl : Ctrl# = 0, 0 :Amount= 87, 87

The second line causes CC32 64 to be output - NO Clone
Channel x: Event=Ctrl : Ctrl# = 32, 32 : Amount= 0, 0
Channel= Match input : Event=Ctrl : Ctrl# = 32, 32 :Amount= 64, 64

The "Clone" directive in the first line passes the CC32 0 message to the next line and this line then finally discards it.

The PC messages are passed though.
Note: No bank change occurs until the PC message is received.

Of course if you send a CC0 = x and CC32 = 0 you will get
CC0 x
CC0 87
CC32 64
The extra CC0 should not be a problem as the synth should just ignore it.

Of course once you have sent a Bank Change (CC0 CC32) the synth remains in that bank and only the PC messages need to be sent.

Hope that helps
Royce

does not work because BOTH conditions are not met (cc32 AND PC)
i want change MSB, LSB, PC only if (LSB=0 AND PC=0)

this change CC0, CC32 and PC

*,Ctrl,32,32,0,0,Y,0,*,*,0,0,87,87 (CC0)
*,Ctrl,32,32,0,0,N,0,*,*,32,32,64,64 (CC32)
*,ProgChg,0,0,0,0,N,0,*,*,9,9,*,* (PC)

BUT also change every PC=0
0 121 2 --- CC: Bank MSB
0 87 2 --- CC: Bank MSB (it is OK, we have change because cc32=0)
32 64 2 --- CC: Bank LSB
9 --- 2 --- PC: Glockenspiel (change 0 to 9)

0 121 2 --- CC: Bank MSB
32 1 2 --- CC: Bank LSB (it is OK, no change if cc32 is diferent from 0)
9 --- 2 --- PC: Glockenspiel (but pc is changing always)

Sorry, you can't have a trigger condition with more than one message using the Data Map.

You could write a script to do it.
Check out the Script in Help and have a look at the couple of examples in the MidiOx program directory.

Bome's Midi Translator might be of use.
Check out his free 'Classic' edition

It is a very cut down version, but it might be enough.

Otherwise you will have to pay for the commercial version.

All the best
