Here is some background.
This brand new section of the Yamaha PSR-500 / 400 user's website is under development. If you would like to contribute ideas, suggestions, help, or instructions, please contact us.
A personal note from proclus-
The reason for this move was that I wanted to run Linux and do midi. As a musician, LinuxPPC was not cutting it for me. Instead of trying to reinvent the wheel, I simply changed platforms. I'm a coder, but, I didn't have the time or desire to write a midi driver for LinuxPPC. Flame me, if you want. If the LinuxPPC midi driver situation has changed, please let me know, and I will remove this rant. Until that time, these instructions will be for the platforms that already have adequate midi drivers. I am fairly satisfied with my x86 music machine.
Linux Midi ConnectivityFirst, hook up your PSR-400 or 500 to the midi port on your computer (sound card may be required).
If you want to do something more sophisticated than play midi files, you will probably need a new driver. In my experience, the native kernal drivers are inadequate for the serious musician. Here are the links for the two major providers of Linux midi drivers. One is open source, and the other is not.
I am using the commercial OSS driver for my Creative 128 card. It cost
me $30. The open source drivers do not yet support /dev/sequencer for this
sound card. If you know of an inexpensive and proven sound card for
serious Linux musicians, please contact
us. Of course, it must interoperate with the PSR-x00 series.
