More than a sample playback module, less than a real synth. Has samples of classic synths, and new waveshapes to mix and match. Also includes portamento, a nice chorus, and really nice low pass filter (settable: 2 or 4 pole, frequency, and resonance). All effects can be used simultaneously on all 32 voices (with different settings for every wave within a patch). Extensive modulation routings. There is "reverb space" to add reverb to the drum kits. 4 of the outputs can be used as effects send/returns. This is not a replacment for an analog synth. It is however one heck of a lot of fun, and has the ability to make interesting sounds fairly easily. The modulation routings alow incredible real time control over sounds with the use of sliders, wheels, pedals, etc.
