Well I was fooling around last night with my ESX and I came across a cool little technique. If you're new to the ESX you'll quickly find out that there are two keyboard parts in which to assign and play synths (single cycle waveforms etc..), I think I may of found a cool little work around to this though-that is aside from resampling

What I discovered last night was a way to play (chromatically using the pitch knob or pitch modulation) a 'synth' on one of the normal sample parts using the roll feature as a sort of loop function (with 'roll' set to 4). I trimmed a saw wave down to about '001' in the sample menu until I had a pretty fat self-oscillating sound going, I then assigned it to a sample slot (slots 1-7B, time stretch parts etc..) in which I triggered the sound live in real time into a sequence while tweaking some LFO's and filters and adding envelopes. Low and behold I had a pretty sweet synth lead in a matter of a few minutes.
This may be old news to some, and something new to others-nevertheless I thought I'd share this tip with you all. Give it a try!
