...what are some non-tracker options? Besides a DAW, of course.
Try any MIDI sequencer. Most DAWs are decended from sequencers. Why do you want to avoid them? You are already working with Audacity, right? It is an obvious progression.
Well, I can't really RUN a DAW right now, I'm running ubuntu linux as my only os because my hard disk is so fcked up with bad sectors windows has a nasty tendency to take hours for moving files around, when it's not having blue screens. Lmms crashes just playing some notes on my laptop keyboard after a few minutes, on the native vst's, not recording. Yeah, not the best situation, but I can't really afford a new laptop at the moment, student costs and all.
Plus I'm a little overwhelmed by DAW's. Once I tried Ableton and no amount of forums or youtube videos ever managed to teach me anything that stuck.
