Problem with some MIDI files with MO8

[Martosax87]

Hello Victor,

From today I have very strange problem: some MIDI files (which I usually open very often) don't open properly and MO8 don't plays them anymore.
Please, check the attached screenshot for more info.

Hi Martosax,

exactly what version number has your Optimizer?
Please send me some of the files that don't open anymore and the settings.

I sent you e-mail with the files.

I want to inform the users that the problem is resolved. Victor helped me immediately.
If someone has same problem in the future, just deactivate "Check program changes" in the options. This can occur when you load files which have been set for Yamaha, but now you want to adjust them for your Korg instrument.

the problem comes from the midifiles as there are some unsupported XG drumsets by the Korg Pa900: "Cherish.mid" has Patch 87 and "Crush.mid" has Patch 5, both not available as a XG Drumsets (Controller 0 = 127).
If you have activated the setting "Check program changes" then the Optimizer tries to replace with a supported XG drumset but fails to do so and aborts loading the midifile.
Deactivate the above setting, open the midifile, chage the drumset to some supported one and save the midifile.
The next version will behave if it finds some unsupported XG-Drumsets.
