Prophet X MIDI SYSEX requests ignored when MIDI Channel is not set to ALL or CH

Hi,

Just thought I would flag a ticket I have just raised with Sequential Support. It is an issue I was aware of but had forgotten about as the other MIDI SYSEX issues I had reported (now fixed) were more severe.

Just wondering if anybody has seen the same behaviour or knows a little more about it. Keen of course to see what Sequential themselves say!

Basically MIDI SYSEX Comms is fine when the Global Setting MIDI Channel is set to ALL or 2, but not any other setting.

I recalled this issue because I have had my Prophet Channel set to 1 for recent recording, and when I tried backing up some data into my px.factory librarian the other day I was getting MIDI Timeouts when requesting data and not receiving anything back from the synth.

I set the channel back to ALL whilst investigating and found it was all working again. On further investigation this morning, I also found it works when the MIDI Channel is also set to CH2 but not any other channels, which is a little strange?

As a general comment, all of my experience with MIDI SYSEX (primarily Yamaha devices) is that there is usually a SYSEX Device ID number to set, which can be ALL or a specific device ID (seperate and not to be confused with MIDI channel), but there seems to be no equivalent in the Prophet global parameters or SYSEX format? Or not that I can see.

I forgot to say that this is on the USB interface. I have not tried the DIN MIDI, which may also be worth checking when I get five minutes....

=== UPDATE ===

Same problem on DIN MIDI

Sequential have added this to their bug list, although no promise of fixing it, which is disappointing.
