Good afternoon Lisa73. Most likely it's not the version of the USB port driver (versions are backwards compatible), but in the file itself. Try to convert the file in the program. Most likely, the table of assigned CASIO 900 tools does not match the data in the file. The synthesizer is very simple, so there are such nuances. I, for example, also did not "enter" a good midi file. After the conversion, the file went in, but its sound was already completely different!
Goodmorning Hant,
Well tried to convert a SMF file in the program itself.
But even that would not load it in to the memory, and the same error message appears that the MIDI Time out was the problem even that the good drivers are selected.
I can tranfer sounds and DSP settings as long that it's not bigger then 100 KB, when I tried that then I get the MIDI Time Out message again.
Can not even load the ALL DATA file, so there's something wrong with the MIDI to USB cable.
To examine that further I connected the 900 with the cable with Cubase and when I played notes on the 900 and the notes where not taken over correctly.
Played in A key but the keyboard started in D and was forgetting notes in the beginning, after a few bars the right notes would sound but out of sync.
When adding more MIDI tracks there where signals in the up following MIDI tracks that where not played and where not coming from the 900 but the cable kept blinking.
Disconnecting the USB cable resulted in a blue error screen in Windows 10.
So I think why the 900 refuses to work with the cable.
Ordered a new one and hoping that it will work beter then it does now.
If not, I really have to consider that there's a fault on the motherboard of the keyboard itself.
Thanks for your reply.
Lisa
