Issue assigning midi to a keyboard note

I´m trying to switch presets in a plugin by pressing keys in my midi controller.

Assign a midi track to the audio track with the plugin. In the plugin I set cc110 and 111 to next and previous preset.

In the midi track I set input transformer to track with 2 rules: Transform note A1 to controller 110 and note B1 to controller 111.

it works but the problem is that increments and decrements are doubled, i.e. I press B1 and next preset is executed twice, same for decrements,

I’m guessing that you are triggering on both note on and note off. Add a transformer rule to filter one of these for each note.

It seems that there is a note off event with velocity 64. Adding a Velocity bigger than 64 condition it triggers only 1 event.

Also, using Midi Inserts Transformer it works fine without any velocity condition.

Is this an Input transformer bug? why they behave different?

P.D chatgpt at rescue. I´ve been using it quite a lot and it helped me to solve many issues.
