Configuring Midi Instruments
« on: January 28, 2021, 17:51:18 »
Hello,
I have a Roland RD700GX keyboard.
I managed to configure OpenMPT to play some of the instruments, but some, including the drumkits need MSB/LSB bank configuration, and I didn't figured out how to set it in the software.

Looking at the instruments library, I was wondering if there was way to have a MIDI GM library for an external MIDI device?

Thanks,

Nelson.

Take the MSB and LSB values from the manual, and compute the MIDI bank number to be entered in OpenMPT's instrument library as follows: MSB * 128 + LSB + 1.
For example, assuming MSB = 93 and LSB = 2, the corresponding MIDI bank in OpenMPT would be 93*128+2+1 = 11907.

In case you have SRX boards installed and want to access them in addition to the internal sounds, here are the MIDI bank numbers:
- SRX-01: 11905
- SRX-02: 11906
- SRX-03: 11907
- SRX-04: 11908
- SRX-05: 11909-11911
- SRX-06: 11912-11915
- SRX-07: 11916-11919
- SRX-08: 11920-11923
- SRX-09: 11924-11927
- SRX-10: 11928
- SRX-11: 11929
- SRX-12: 11931
- SRX-97: 12002
- SRX-98: 12003
- subtract 128 from each of those values to access the corresponding drum kits

The MIDI Library is only used for loading MIDI files (they will use the instruments defined in the library).
