Op1 hidden fx?

Hi! first time poster here :slight_smile:
i find an hidden filter fx while loading a preset from op1.fun (the preset is called piano)
i can’t find a way to use this fx on my own preset… somebody can help me?
(sorry if it has been asked before… i search in the forum but i found nothing)

No direct way. Just use that patch you downloaded and replace the synth by pressing Shift + 1.

No idea why they still haven’t added this Filter FX to the menus. It’s very useful.

Iter engine is okay too.

u can unlock them in your menus for normal use by using the firmware repacking tool

see this thread for info

This is the hidden “filter” FX?
In OP1 there is an hidden “ITER” engine and “FILTER” FX that can be found in (and unlocked through copied/pasted from) this patch:
