However, it doesn't change the channel, but I don't think you really need to given your setup. I've had a look at the manual( ) and the list there shows that the PCR can transmit program change, which should change the sound on Garageband or any midi synth/sound module. Standard midi supports a total of 127 programs, there is a default set of instruments assigned to these programs, but you should be able to modify and tailor it to your needs, assuming Garageband is worth it's salt. There is a midi message which changes the instrument called "program change". Midi has support of 16 simultaneous channels, which means it can transmit 16 sets of 'sheet music' if you will. Like sheet music instead of the actual music being played. as compared to the actuall analog sound wave that results once you feed a midi piece into a synth or module.

In laymans terms, it is what is being played, in terms of which notes, how long, how hard, with what changes over time etc. Well, I don't know anything about Garageband, but I have looked at the PCR-800 before and plan on getting one myself once time and money permits.īut, the basics of midi in a nutshell: Midi is a digital abstraction of music information.
