I find sometimes when I've recorded on one track a certain drum sound, playing it using my PC keyboard, and then I go onto another track and select another set of drum sounds from the list in Impulse, I find the previously recorded drum sound has changed to match what the corresponding PC key is on this new drum set. It rarely happens but particularly seems to occur when using the vibro type drum instrument.
It's really annoying as I want to keep that instrument in there, and I can except if I go to a certain set of drum sounds. Then it switches weirdly to another one on the same PC key.
Anyone else encountered this? It means right now that I can't select a drum sound from the next set or whichever set makes this happen. Grr.
