Is there a way to change instruments in drum patches (for example change bank 128 preset 0 #80 to #81 in the standard kit) using the config file?
You can change any instrument you want in a drumset. If you are using soundfonts then this is an example of how you would change instrument #80, the triangle in the room drumset 8 to be the same as triangle #81 in the same drumset. To use a different drumset, just replace the 8 in both lines with another drumset, like “0” for the standard set, and of course you can change the volume and panning as desired as well: drumset 8 80 %font “MyDrum.
