I use Roland GK-2A divided pickup on a Yamaha steel acoustic guitar with an older Roland MIDI guitar gear GI-10 (no synth, just pitch-to-MIDI converter) for recording guitar strummings into MIDI sequencer. Lately I purchased a Godin ACS-SA nylon strung guitar with built-in GK-2A pickup which has both the GK-2 13-pin connector (for MIDI) and 1/4" out for amplifier/effects. It is very interesting product and the mix of its own amplified sounds and synth sounds it triggers is very amusing. Uncle Dave is correct, even the old GI-10 has a hold (sustain) pedal connection that allows you to sustain a particular chord as long as you press down on the sustain pedal.

Clif's idea of using Roland PK-5 should also work especially using PK-5's poly mode in which you can step on multiple pedals representing the components of a chord. You will need to have a MIDI merger device like MIDIman 2x2 to merge the MIDI out of Roland GI-10 or GR-30 etc. and the MIDI out of the PK-5 pedal board to the MIDI in B of say, Yamaha 9000 Pro/PSR9000, Roland G1000/EM2000, or MIDI in 2 of Solton X1.
