SysEx not working

[batata004]

Hi,

This library is awesome and I managed to make everything I need to work, except SysEx. I have an Arturia midi controller and I got in touch with then to know how to send the command OCTAVE UP. They told me the SysEx message should be:

`F0 00 20 6B 7F 42 02 00 00 11 7F F7`

Then I used webmidi library to send the message. I used this simple code below, extracting the device ID and data from the command above (provided by the manufacturer itself).

WebMidi.outputs[0].sendSysex([0x00, 0x20, 0x6B],[0x7F,0x42,0x02,0x00,0x00,0x11,0x7F]);

But nothing happens after executing this code. I used {sysex:true} and got no errors, everything looks fine. But the SysEx message looks not being understood or sent. Any other messages (notes, command change...) work pretty well with webmidi library.

As far as I can tell, WEBMIDI.js is behaving normally. I tried your code and directed the output to MIDI Monitor (a Mac app to troubleshoot MIDI communication). As you can see, the output is as expected

I'm tempted to say that the problem is either with your device or with the command itself. Let me know if I can help any further. In the meantime, I'm going to move this issue to the discussion section.
