How to Make Oxygen Pro Pitch Knob Go Full (100%)
If your M-Audio Oxygen Pro Pitch Wheel does not fully go to 100% and -100% percent, then I will quickly share how you can fix that for your Virtual Instruments in FL Studio.
This isn’t a perfect fix, but it does allow your pitch wheel to fully go up and down on virtual instruments in FL Studio for normal operation.

The answer is to increase the pitch range on the plugin window.
Here’s an example with reFX Nexus virtual instrument (see why I like ROMplers):

Once you increase the Pitch Knob Range of the Virtual Instrument, you will see the Pitch Wheel start increasing and decreasing at larger values.
You will have to play with how much pitch range to increase. The image above shows 8.. but you may want to go 12 for some Virtual Instruments.
If you increase pitch range too much, the pitch wheel becomes way too sensitive, so you’ll want to set pitch range at a lower number where you can fully max out, but still have control for powerful operation (12 seemed to be a sweet spot).
I will share, I do not use the Pitch and Mod Wheel when making beats. I prefer to automate stuff with the mouse in FL Studio.
