since long time I am thinking of buying a guitar with a Midi-Pickup (Frame works), but was not sure if it is the real thing to me. Now with the Strad and the Cello perhaps things may change.

Has someone used a midi-guitar to control the stringed instruments? I thought that the expression control with a guitar is comparable to a violin (of course without bow ) or am I mislead in the sense that the rmc-pickups do not transmit these kind of data.
