hi! i found within my father guitar gear an old (not that old) Roland GR-30 guitar synthesizer, with a GK-2A guitar pup. since i was looking for a midi keyboard controller for recording midi data in my pc, y figuered out i could i could use my bass to recrod the midi data , cause i feel much more comfortable with bass than with keys the problem is that the GK-2A is meant for guitar. and also, i remember it for being very slow tracking the lowest stings of the guitar. my question is: is the tracking done in the pup, right? so if i get a newer BASS GK style pup, it will actually track better... so i can use the roland synth just to convert data and send it midi into the PC, right? my question is: is the GR-30 compatible with iny GK style pup? is the tracking in the PUP or in the GR? is the GK-2B pup tracking fast enough for funky playing? will the GR-30 work exactly the same as a Roland GI20 module? well thancks for any input!
