Change VST presets from Midi?

Hi,

I’m using Ardour 6.5.0 64 bits with windows.

I’ve got a midi track with Synth1 on it.
At the beginning of the track, synth1 is using the Program 01 on bank 01. I’d like to make it select the program 19 on bank 01 automatically after a while.

I thought about a basic idea of “If notes are on channel 01, keep program 01; if notes are on channel 10, change to program 19” but I don’t know how to achieve this?
I have the X42 “Midi not to PC”, but I don’t know how to use it.
I see the option to filter the channel, I think I understand how to chose the note to trigger the program change, I see the velocity option, the only thing I don’t see is the program change itself.
Where do I enter “use program 19 on bank 01” ?

I’m not very good at using Control Change. :confused:

Thank you.
