Tx Biohazard No Mod Wheel Vibrato

[midiguru]

In the MIDI page, the LFO2 to Pitch Destination cannot use Mod Wheel as the Source, even when the amount is set to 100. So, no vibrato.

I know the mod wheel is routed correctly to the synth, because I can assign it directly to a parameter using the standard right-click "Link to Controller" command.

Am I doing something wrong, or is this a bug?

Also, by the way, CC types 2 through 5 cause all sorts of Toxic B. parameters to change, even though I never assigned them. What's going on here?

For reference, FL Studio version is current. I'm in Windows 11 Home.
