Hi everybody,
my PSR8000 has a strange (and annoying) problem.
It seems impossible to send correct sysex messages, but it will recognize perfectly sysex arrived as input.
If I start recording into a sequencer (I use cubase) what I play (included DSP on/off, change sound, equalization, etc...) I get a long list of sysex messages(besides the notes, of course), but if I play them back it doesn't sound like I played.
Effects do not switch on, etc...
I DO NOT filter any sysex, I play in Local Off (using Cubase Thru).
This happens both with MIDI and with serial connection.

Does anybody have the same problem??
Or how did you bypassed it?
Could it be a misfunction of my PSR??

Please, help!
Thank you,
