Re: guitarists: triple play?



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.
