yes I wanted that also, but in real band when bbw2.exe generates up multiriffs it writes them to wav in C:\Users\Band In A Box\AppData\Local\Temp - in band in a box all the tracks seem to be running in memory - it would have to write the whole track to wav first then generate up multiriffs - this way you could also edit them in the Audio Edit windows - being in ram I suppose this is where the speed comes from, play while still generating the rest of the song ?
