I have an external controller that I’m programming various SysEx commands for controlling some of the MOXF configurations.  One of them is to toggle the MIDI I/O setting from USB to MIDI (i.e., Utility>MIDI>Other>MIDI In/Out). Based on the documentation in the Ref Manual, p. 125, MIDI Parameter Change Table (System), I’m trying to execute the following commands:

F0 43 10 7F 1C 01 00 00 18 01 F7 USB
F0 43 10 7F 1C 01 00 00 18 00 F7 MIDI

The MOXF is not responding to either of these commands.  I’ve tried sending them from the PC as well as from the external controller.  Any ideas? 

Thanks

Mark

In case anyone else is trying to follow along, that would be in the MOXF Data List.

I’m trying to execute the following commands:

F0 43 10 7F 1C 01 00 00 18 01 F7 USB
F0 43 10 7F 1C 01 00 00 18 00 F7 MIDI

The MOXF is not responding to either of these commands.  I’ve tried sending them from the PC as well as from the external controller.  Any ideas?

There are two considerations.
1)
F0 43 10 7F 1C 01 00 00 18 01 F7 USB
F0 43 10 7F 1C 01 00 00 18 00 F7 MIDI
The emphasized byte should be 00, not 01.

2)
The following might be obvious, but I’ll mention it anyway…
The MIDI In/Out Parameter can only be changed via SysEx when the MOXF is receiving via the port not being selected. That is, when the MOXF is set to receive via 5-pin MIDI, you can send the message to select USB via 5-pin MIDI, and the MOXF will switch to that. Once done, the MOXF will only respond via USB.

Conversely, when the MOXF is set to receive via USB, you can send the message to select 5-pin MIDI via USB, and the MOXF will switch to that. Once done, the MOXF will only respond via 5-pin MIDI.

In other words, you can’t toggle the setting back and forth just by changing the data byte, unless you keep switching the port you’re sending the message to as well.
