TG100 is YAMAHA's 28-polyphonic 12-bit PCM (called AWM - Advanced Wave Memory) playbacker.
CBX-T3 is an identical model without an LCD.
They are the most editable (though limited) synth among YAMAHA's AWM playbackers.

I made a 'Performance Editor' for TG100 that can layer 2 Voices (4 oscillators), with SoundDiver.
