And now we can sing the MIDI-buff theme song! "Heeeere I come to save the Daaaaaaayyy!"
Hi fellas! What seems to be the trouble? Out of powdered toast? Ah yes... *scrape scrape*
Now, MIDI stuff...
First thing first, connect these cables PROPERLY- they are usually labelled, so joystick part in normal spot, MIDI IN and MIDI OUT. These should be labelled plainly - be grateful you're not dealing with pure MIDI-only cables where you have to cross from in-to-out... Moving on;
DRIVER: Music be the MPU-401 (or similar MIDI device... It doesn't look like Cakewalk is seeing ANY MIDI drivers installed at all. I presume your keyboard is General MIDI compatible?
You're not worried about drivers for the keyboard, since it's CONTROLLED by the MIDI output of your motherboard - that's what you need.
For example, I have the following MIDI output options on my system:
Roland MPU-401
Santa Cruz (internal synth)
Santa Cruz External MIDI
Roland Serial MIDI Out A
Roland Serial MIDI Out B
See anything in the list at ALL for MIDI output?
