Dorico using CC21 and CC20 to nudge playhead forward and back? How?

[Jon_Magill1]

It seems that I have somehow set Dorico to interpret CC21 and CC20 as nudging the playhead forward or back. I have no idea how this as happened and only worked it out when trying to work with Spitfire libraries and adjust Vibrato and Variation parameters using my MIDI controller. All other parameters from the controller work as expected but CC20 & CC21 are not passing through to the VST and so do not change the parameters. The movement in the playhead is very subtle and it took me ages to work out what was going on .

Can anyone help me with removing this mapping/configuration ?

I am running Dorico 6.1 Pro and both SSO and BBCSO libraries. My midi controller is an Alesis Vi49 keyboard.

Ok . Solved it. Somehow I had set a Key command using MIDI Learn and assigned it to “Next Frame” . Traps for young players.

I’m curious how you managed to set this by accident. Or was it deliberate and you just forgot that CC21 is needed for vibrato in the SSO (which I use all the time)?

Ha, Ha. About a year ago I was messing around with a Behringer control surface , trying to map some switches to Dorico commands and I used CC20 and CC21. This was before I knew that they were used in sample libraries. I completely forgot about them and only realised when I was looking to set another key command yesterday. I’m a year older and a year wiser.
