An 8 bar loop done in fl studio 7 using silverbox 303 clone vst. No effects used just automted cuttoff/env mod/decay. Got a few of these. Done in 32 bit 96000khz so you might want to resample for your project.
Two measures of squelchy acid bass with piercing synth chords. Created in lmms, further effects applied in audacity with valhalla supermassive. 140 bpm, a flat hungarian minor.
Generative modular acid line sequenced with my own custom script that is specialized for non-quantized sort of strings of notes. I mangled the envelope quite a bit though so it just sounds more swingy than anything i guess. Not sure what the bpm would be. Would be better if it were cut up for one-shot sounds maybe.
A basic beat using acidmachine beta online. Tempo 70. Here's a link to free the web browser program from use with google chrome: http://www. Errozero. Co. Uk/acid-machine/an interest kick pattern.
