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.
