Hi,

Welcome to the Synth Zone.

I checked out the manual on Peavey's website and discovered several things. First, while it is possible to transmit MIDI control change messages to the Spectrum Bass Module to adjust things like filter cutoff and resonance, envelope generator values, velocity curves, LFO shape and rate, etc., the edits made here can ONLY be held in the buffer memory and NOT saved to a permanent preset location. The manual states that edits within the buffer will remain at power down but my question would be "for how long?". I certainly wouldn't take a chance on expecting your edit to be there when you get to the gig. And keep in mind that even if the buffer memory was absolutely dependable, you can only have that one edited preset.

The Soundquest editor will make it easy to edit presets for the Spectrum Bass, but you will still need the computer with you and connected to the module in order to select multiple custom presets (Soundquest can store an unlimited number of edits and transmit one at a time over to the module).

In looking at the System Exclusive and Voice Architecture in the back of the manual, there is a lot of versatility there. a total of 52 waveforms, good control over filter and amplitude envelopes and so forth. This would be a fine module for home or studio use, but unless the factory presets are perfect for your needs as is, it is a limited for live use.
