I was able to see much more info from my old PSP diskette. The newer diskettes and downloads from Yamaha do not show as much info. Which leads me to conclude the protection scheme has been beefed up.
midi2CD does work very well, for me. When I program with it I remove the SysEx data as it isn't needed. (Unless I'm missing something.) I inspected several PianoDisc CD's using the Midi Monitor program, none of them seemed to supply SysEx data. And if you are just syncing to audio, patch information isn't needed. The timing data is on the CD.
This SRS recording feature is a bit "dark" because it will not allow you to edit the SRS sequence once saved on the DK. Yes, you can "live record" and add as you go, but will not work if you have a polished sequence that you would like to pair with a CD using SRS. The identity of the file is "orphaned" once you modify it using an external editor. It changes the file's name. I've tried to edit it to reflect the same name, but it will not work. This is something I would like to see if we can change.
