I know this sounds kinda dumb, since most of the time, when using sequencers and the like, we like to stay as far away from the General MIDI stuff as possible, as it tends not to sound the best, but I am running tracktion and it doesn't recognize Quicktime MIDI player as an output. And GPO is the only sample library I have. Not that that is a bad thing, but I have no standard drum set or other stuff. I need something that is either really inexpensive or free.
I know next to nothing about VSTi's, so I am sure there is a freebie GM VST out there somewhere, I just don't have a clue where to look first.
