Hi there,

I've got a new PowerBook G4 with GarageBand, Logic Express and an Edirol PCR-30 keyboard plugged in via USB. I've run the installations for Logic and the keyboard (these weren't pre-installed), but, for some reason, the I'm not getting any sound output when I play the keyboard, through Logic or otherwise.

Signals appear to be being transferred, according to both the transport bar and also the MIDI setup in "Audio MIDI setup".

I'm not entirely convinced that the MIDI is correctly set up, since the only entity in the MIDI devices is "Edirol PCR" - should this
have an external input as well or is it an "all-in-one" affair?

I'm not hugely experienced at setting up Mac's like this so I'd really appreciate any advice you could offer me!

Thanks a lot,

Polly

The Edirol PCR-30 does not have any sounds itself as it is a controller keyboard.

If you have MIDI information on the transport bar of Logic then the Edirol PCR-30 is set up correctly. You just need to play a track that has a vitual synth assigned to it. e.g. ES1 etc....

You are either playing MIDI tracks which don't have any external MIDI sound source assigned to them (do you have any hardware synthesizers or modules?) or an audio track which is used for playing audio files or an Audio Instrument track which does not have a Virtual synth loaded.
