Sysex

Error, the second photo does not show the command sent by OnSong but the response from the VLP, I believe. I'll check...

The message in the second photo is indeed from the VLP, when it apparently received the sysex from OnSong. I am currently unable to obtain (in the monitor) the sysex sent by OnSong. I'll try again later, I have to go to work.

One other thing worth checking out could be to only send one sysex message at a time and see if that is processed correctly. Some devices need a bit of time to process sysex messages.

Yeah, that is something I'm definitely focused on testing. Especially given SYSEX messages are a lot larger than other MIDI messages and so I might have to be more careful about how much time I leave between each message.

For example, on my X32 mixer, to load a specific effect into one of the effects block and then set all the parameters (e.g. maybe I use the same timed delay, but with different delay time and decay time, in different songs) is generally 12-13 SYSEX commands.

Hello Peter, here is what I get from OnSong with the MIDI Monitor when I send the sysex sequence.

The same message sent by ST4.

Oh... There are some zeros missing in the one sent by ST4, and I just figured out why. It's the tool I used to remove the spaces. I'll try again by doing it manually.

jfduval In case it is relevant, don't forget that you no longer need to remove the spaces between the bytes which removes the risk of 'bad' search & replaces. Peter made this change to allow the spaces a few builds ago.

Thanks Anthony, I missed that information. I was about to give up... Unfortunately, it still isn't working, so maybe I'm doing something wrong. That's enough for me tonight. I'll take a fresh look at it this weekend! Thank you.

I just did a bit of research on SYSEX for the TC Helicon VoiceLive stuff... OMG, what an absolute shitshow. I though having to deal with OSC to SYSEX conversion with my Behringer X32 mixer was bad! All this 'the commands have to be packed a certain way and certain size' mularchy with the VoiceLive stuff!!

Maybe someone else in this community using one of these devices that also wants to move to using native SYSEX commands from ST4 (might have previously used MIDI remapping with ST3) might want to join the party.

So, am I correct that this issue just resolved itself? If yes, I would leave the thread open for further discussion but mark is as "closed".

Yes, of course. Thank you, Peter.

Thank you too, Anthony. I'll keep looking into it, and any help will of course be appreciated!

If anyone has any ideas, here's where I'm at right now.
My SYSEX command is this (it contains 3 blocks):

F0 00 01 38 00 69 20 00 01 01 2A 45 46 46 45 54 53 20 4F 46 46 00 00 00 00 00 00 00 00 4D 01 F7 F0 00 01 38 00 69 21 00 7F 7F 7F 62 00 00 00 00 00 00 00 05 00 00 00 03 00 00 00 00 7F 7F 7F 77 7F 7F 7F 7E 7F 7F 7F 7B 7F 7F 7F 6C 7F 7F 7F 6E 00 00 00 64 00 00 00 64 00 00 00 64 00 00 00 00 00 00 00 01 00 00 00 6E 00 00 02 10 00 00 02 10 00 00 00 32 00 00 00 02 00 00 00 0E 00 00 00 6A 00 00 00 00 00 00 00 00 00 00 00 00 0D F7 F0 00 01 38 00 69 21 01 7F 7F 7F 79 00 00 00 3B 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 05 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 36 F7

When I connect my iPhone or iPad, I get this:

When I send the command with OnSong, I get this:

And when I send the same command with ST4, I get this:

It seems that the first set of 32 bytes is not being sent with ST4. However, I have exactly the same command (copy and paste) in both applications. As a result, my device (VoiceLive Play) responds as it should with OnSong, but not with ST4. Any ideas?

P.S. Sometimes ST4 stops sending the SYSEX command (both with the iPhone and iPad). However, other MIDI commands continue to be sent correctly.
