MIDI CC commands don't work on first select of song

Hshevitz

I am using ST3 to send midi commands to my Boss GT-1000 to select patches and then turn on specific effects on song select. When I select a song the commands are being sent and the appropriate patch is selected, but the CC command is not turning on the effect. If I run the same commands a second time it works just fine. If I test this from within the song lyrics, it does the same thing where I have to run/test the midi commands twice from within the editor.

Here's the midi command line:
[midi: PC0@1,CC4.127@1]

We have discussed this issue a couple of days ago. Seems like some devices are not able to process a program change immediately followed by a CC command. I guess they need a bit of time to reconfigure the device after switching to a new program. That's why it works the second time (it does not need to change the program as it is already selected).

peter Thanks Peter! What about a midi command to "wait"? This is a similar problem that I have with OnSong and resolved that by adding a 200ms wait between some commands.
OnSong midi line:
MIDI: 0@0, WAIT200, 0@1, CC4@0

In ST3 this can only be done by timed midi messages. But that requires the playback to run.

The midi world is a strange place, I use a program called Showmagic on pc, it indicates on its midi monitor that it’s receiving info from st3 and touch osc etc, but I have to send some commands 3 times to get a result. It’s annoying but there’s little we can do, as often it’s impossible to duplicate an issue 😀

try putting the same command in a few 100 ms after the 1st command so basically your putting the same command twice with a time gap it may work

That does not work if both commands should be sent before playback starts.

well can't he send the command once he's hit the start button. you always have a lead in to the song,of a few seconds has long has it changes before the audio starts should be no problem
