I can't find any MIDI switch on my Yamaha PSR3000.... there WAS one on my EZ-30.

I'm not getting anywhere with the MIDI cables so I have tried the USB again. I had to install the driver for a second time.

This allows me to get sound in and out but I don't get the voices that I want - a step up from the MIDI cables (I just don't understand why they don't do anything).

I chose the PSR-3000 for its great voices and would like to use them in an environment that is much more visual than that provided with its numbers-based on-board sequencer.

I thought to get access to those voices using a PC I would need an "Instrument Defintion File" for my particular model.

I've requested a Piano voice and am getting "WahClavi".....

I can't believe this isn't more straightforward.
