Load in up to 4 samples, visually edit the spectrum, filter and modify. Most folks start with a preset, then mod it. Most interesting for me starting with something I've recorded myself. Make sure the synth is in Mono mode if driving from the bass. Cleans up the attack slightly. The synth is a substantial CPU load with the interface open. Cool sound reminiscent of the neat overtones of an old school sampler, but a bit too squirrely to do any kind of horn line other than a reinforcing long note. Ends up being used more as a sound effect. Limited general use.
