I am trying to read in a midi file that I generated using Finale 2012 on OS-X 10.8.3. At first I get the usual message:

midi channel 1 using instr 1
midi channel 2 using instr 2
midi channel 3 using instr 3...

etc. corresponding to my massign statements.

But then after "Reading MIDI file 'myfile.mid'..." and other messages, I get the following on the console:

midi channel 1 now using instr 1
midi channel 3 now using instr 1
midi channel 2 now using instr 1
midi channel 4 now using instr 1
midi channel 5 now using instr 1
midi channel 6 now using instr 1
midi channel 7 now using instr 1

I am using Csoundqt 0.9.3 and Csound 6.09 (I first had the problem in 6.08).

I tried resetting the assignments by calling an instrument with the massigns in it, but the same thing happens. Thanks for your help.

Hello Bill,

I wonder if there are “Program Change” channel messages in your MIDI file which cause this to happen.

Best regards,

Jacques
