Some manufacturers show MIDI program change numbers starting at 1 while other show them starting at 0. In the H9 they start at 0. So, perhaps, the device you’re using starts program change messages at 1, and your 125 corresponds to Eventide’s 124?

thanks for your kind reply.

you’re absolutely right. However it seems to be correct to send PC#124, even though the controller actually outputs PC#123, since it brings up the “TUNER” label in the H9.

If I try instead sending PC#125 alone (PC#124 in H9) it just toggles the H9 state from active/bypassed, which is correct according to the default H9 midi map. No tuner. 

However I observed that repeatedly sending just PC#124 (H9’s 123)  causes the H9 to cycle through these four states:

1- just TUNER label displayed but no guitar audio 

 2- back to effect sound 

3 – perfectly working tuner 

4- back to effect sound 

 and so on…
