The problem with hydrogen is it can't use the wealth of drum samples out there in sf2 and gig. I need control over eq/level/reverb of each group when I mix. There was some talk a while back of a midi filter for alsa that might do this sort of thing. Does anyone known if it got written ? Does anyone known how chanllenging the ALSA midi API is ? Is this the sort of thing I could knock out in an afternoon or is it a project ? Cheers, Bruce.
