General midi instrument allocation to program numbers is well known and documented on the web, however, I use a Roland R5 drum machine and so needed to work out which pads to hit to get the right midi note numbers generated to be able to build a drum track which would work OK on any general midi compatible instrument - including of course computer music cards such as the Soundblaster. And the reason? So that I could use my own music in my own DOOM II WADs.
So, after a bit of work I came up with the table which you see below. Here, Each of the standard midi note numbers and associated drum sound is given, along with the equivalent pad bank and drum sound on the Roland R5. It proved invaluable to me and I hope it is of some use to others.
Although Roland were effectively the originators of the standard for midi drum note assignments, things have moved on since those early days, and a number of the general midi note number sounds simply do not have equivalents on the Roland R5; notable examples are the Guiros, Cuicas and Triangles. However, it is obviously possible to generate the required note numbers just by using the appropriate pad in the correct pad bank. For this reason, I have included all the drum sound equivalents, even where the actual sound on the R5 is completely different.
R5 sounds marked with an asterisk (*) apply only to my system and are not available on the R5 as shipped.
