Title: Mapping Program Change to NoteOn gives NoteOff
Post by rkwb on Sep 17^th, 2004, 8:18am

Hi Jamie !

Still (or again) working on my old topic "total recall" for a live band, I tried to map an incoming Program Change to NoteOn, which is what would help me to achieve what I want in Cubase.

So I set up a Translation Map in MIDIOX:

MOXMAP Version 5

[Map]
1,ProgChg,*,*,*,*,N,0,*,NoteOn,*,*,*,*

[Options]
WaitForFullNRPN=0
MapNRPNDataIncr=0
SendFullNRPN=0
ReverseDataEntry=0

However, when I monitor input and output I can see that the resulting output is NoteOff

Input:

TIMESTAMP IN PORT STATUS DATA1 DATA2 CHAN NOTE EVENT
75267909 2 -- 192 2 --- 1 --- PC: Electric Grand Piano

Output:

TIMESTAMP IN PORT STATUS DATA1 DATA2 CHAN NOTE EVENT
75267909 2 2 144 2 0 1 D -1 Note Off

What am I doing wrong as I can tbelieve that this would be an undiscovered bug ;-)

Thanks and best regards
RKW

When you issue a Note ON, you also have to specify a velocity. It also happens that a velocity of 0 equals a Note OFF, so you'll want to prevent that (although I suspect you'll want Note OFFs at some point?).

Program change is a 2 byte message, while Note ON is a 3 byte message, so all your mappings will have 0 velocity (and thus be Note OFFs). To fix this, specify a velocity:

MOXMAP Version 5

[Map]
1,ProgChg,*,*,*,*,N,0,*,NoteOn,*,*,100,100

This will map Program Change into a Note On. The Pitch will be the patch number and velocity will be 100.

YAPADAPADOOOOOOOOO !!!!!!!!!!!!!!!!!!!!!!!

That was the final little thing !!!!!!!!

I'm now able to remotely control Cubase to load the complete setup for any song of our five piece band with a any MIDI controller within a second !!!!!

Thanks a lot !
