RE: guitarists: triple play?



Per, do you have a preferred one of them?

I've started with "MIDI guitar" in the late eighties, with the first 
models and have recently been using the GR-55 (+ GK3 pickups), but I still 
prefer none of that but rather playing my usual audio signal into some 
audio-to-waveform converter. These are available as software plugins for 
those who play through a computer and then there are some new digital amps 
sporting these algorithms as well. This gives you a direct monophonic 
synth tone with immediate musicality, i.e. no latency and accurately 
following how you're shaping the tone on the physical instrument.

Some might not like playing monophonic lines but I think that's great for 
live looping because in a few seconds you can build any chord in a looper 
by layering the required number of notes.
