Isn't ams a soft-synth that is controllable by MIDI?  I don't think it's 
capable of doing anything with PCM audio input, you'd need a MIDI keyboard or 
something like Rosegarden to control it.

If you want to build an effects rtack for your bass, you should use jackrack -- 
it's lets you stack up LADSPA plugins like you would an effects rack and 
process audio.

That would be a real trick.  MIDI is easy because it is a defined protocol with 
a finite set of instructions... you are basically doing a digital-to-analog 
conversion of MIDI control instructions to a defined set of voltages to control 
a synth.  There might be something out there, but I daresay it's probably not 
software-based.  You are probably better off getting a bass or guitar MIDI 
interface and using that.
