Thanks to you all for the responses. 905133... Thanks for tracking down the .ins file. Ridiculously, I had found that myself but due to downloading it incorrectly, Windows 10 decided to turn it into a text file. Anyway, I downloaded properly this time and IT WORKS. I now have a proper list of Banks and Patches I can use in the track setup, so many many thanks!
If the forum is not dying of boredom with this topic, I am afraid the other methods of inserting a bank/patch change event defeated me. Based on what I read, I decided the bank select method should be Normal. The Help file seemed to indicate it should be "Normal" because the Korg didn't respond to only one of the methods. The formula said the bank number should be CC0 x 128 + CC32, which in my case =2051. I put this in the bank select (not sure if it was accepted) but then the patch box just showed normal GM patches and my PC event changed the patch to a Rhodes Piano, not the guitar indicated in the Korg manual.
Education would be welcome... Can I put in three events - one for CC00, One for CC32 and one for PC?
And Bob, thanks for interesting idea regarding the conversion to audio. Something I will follow up.
