Mark, your problem with using the Korg editor on a Mac is not with OS 9. I use 9.1 and have no probs. I put the Korg driver straight into the System folder & set up as normal - making sure that the setting on the Korg is correct for a Mac. The only difference is that I have a Beige G3, and so don't use the USB MIDI, only thro the serial port & to host connectors with a standard Mac printer cable. I use the Korg (05R/W in my case) as my MIDI interface for the computer. I know that this is not very positive, but it shows that the Korg can work on OS 9.1 (I have also used it successfully on OS 9.0). I am about to upgrade to 9.2... Who knows! My wife has a G4 on OSX and 9.2 - but no MIDI interface, otherwise I would try it for you. Best wishes Clive. ---------------------------------------------------------------- This message was sent through the Korgy Park mailing list.
