Knobs & Sliders

This is normal. If the knob moves, the Patch or Effect becomes edited - and you wouldn't want to edit your sound every time you moved the mod wheel. SysEx Parameter Changes do edit parameters, and so the knobs will move correspondingly (though you can disable this if you wish, using the Preferences window). MIDI changes to the mixer windows (volume, pan, etc.) edit the Multi, and so the knobs and sliders will move there as well. Top of Page Control Panel knobs are jumpy when moved Control Panel knobs can be jumpy when moved if you have all of the following checkboxes enabled simultaneously in the OASYS PCI Preferences: "Send MIDI parameter change messages" "Receive MIDI parameter change messages" "Update control panels from MIDI" or "Update Mixer Windows from MIDI" "Editor responds to OMS/Freemidi Controllers" (MacOS) or "Editor responds to MIDI controllers" (Windows) This combination of settings can cause knobs (and other Control Panel objects, such as sliders) to respond strangely, because the settings create a SysEx feedback loop. To eliminate the feedback loop and solve the problem: Turn off the Send and Receive MIDI parameter change messages when you are not using a sequencer, OR Turn off "Editor Responds to OMS/Freemidi Controllers" (MacOS) or "Editor responds to MIDI controllers" (Windows) when you are using a sequencer.
