Avoid Pitch Response from the Sampler's Part Inside FL Studio's Patcher

[Domenico KVR]

Greetings. I don't know if I should have posted this in the VST section instead(?) Tell me if this is the appropriate place.
Anyhow, I'm trying to make a combo in FL's patcher. I want one or several synths layered with a percussive sound that does not change pitches according to the note.
An example could be a kick n' bass, or a synthesized mallet sound.
Thank you!

P.S. Doing this in Kontakt would also be quite useful, if anyone here has scripting skills.

Cheers.
