MIDI Designer is modifying my sysex strings!

Question

This is from a user comment here.

What's happening is that MD appears to insist on modifying the strings after I've typed them in. For example, I reckon that to tell Auria to PLAY, I need to send the SysEx "F0 00 00 06 05 00 B0 77 7F F7" so, ignoring the first F0 and last F7, I type "00 00 06 05 00 B0 77 7F" in to SysEx properties field and apply it. However, MD has actually saved it as "00 00 06 05 00 7F 77 7F " so it doesn't work as intended!

Answer 1

Unfortunately, that sysex is invalid, because each sysex byte can only go from 0-127. The B0 is 176, so that won't fit in one byte. If you're sure that this values need to go there, but could occupy more than one byte, use the MIDI Byte Calculator to figure out your bytes:

in two bytes, it's 01 and 30.

I hope this helps, comment back if you have other doubts.
