Mainstage + Qlab Program Change Issue

Hi guys,

We are using Qlab over the IAC MIDI bus to send MIDI Program Changes to MainStage.

HOWEVER we have a huge issue where MainStage is interpreting the message incorrectly and when we send for example

Program Change #001 MainStage is changing the patch to that assigned one higher (as if we have sent Program Change #002)

I've verified using a MIDI monitor that the message from Qlab is correct; has anyone seen this issue before where the program change is one value off?

There are 2 different MIDI program numbering standards: 0-127 and 1-128.

In the MIDI pane of MainStage’s preferences, you can configure which numbering system it will use.
