ok i've uploaded the test project if anyone is interested to try it out. the project is saved in Ableton Live7 format, but the recorded audio files from my TI are there (pay no mind to the start points). the MIDI is just a repetition of the same 8-note chord quantized to 8th notes. also included is the sysex of the single test patch i created to illustrate the issue:

for each recorded audio file, i changed OSC1 to a different oscillator type, starting with a classic sawtooth. oscillator balance is at 50%, and OSC2 does not change at all. i turned the filter cutoff down and set the filter envelope to a quick decay (sustain at 0) and moderate release. same goes for the amp envelope. otherwise, there are no effects, no doubling, etc. just plain-jane synth sounds that should not be taxing the DSP at all.
i've sent the same project along to Access support, but i'd be curious to know if anyone else has the same issue.
