I know I mentioned on IRC yesterday that you could probably do this with 
Pd easily enough, but I've just done it in SuperCollider for a laugh:

{SoundIn.ar(0, LFPulse.kr(10, 0, 0.7, 0.5, 0))}.play

This is just taking the incoming audio and modulating its amplitude with 
a pulse wave; the "10" there is the frequency in Hz, and the "0.7" is 
the pulse width.

A better approach might be to set up a very simple synth in AMS with 
just an audio input, an envelope, and an output. Then, you can feed it 
both audio, and a MIDI signal from an arpeggiator to get the effect 
you're after.

Thanks
