Midi learn didnt work I think when I tried it on with my nektar midi controller in arturias vst for changing presets.
Tried CC 0 and CC 32 was not able to change presets in arturias vst. Maybe you need to use some other message?
CC0 and CC32 is in standard midi used for Bank select.
Keep in mind that a midi CC only work if the messages can be used by an recieving part.
In Arturias synths i would use other midi CCs than CC0 and CC32 fto assign to a previous or next preset button.
Keep in mind, that applications can have reserved midi CC parameters that can't be assigned freely. Arturias does have reserved parameters.
Arturias applications shall be set in Midi Learn mode to assign controls. That you - as with other things - can read about in the manuals.
I don't know if your Nektar controller also need to be set in a certain Midi learn mode for this to work. You have to look in the manual for your controller. Can't you find an instruction video or guide for this?
Normally when a Arturia application is set in Midi learn mode, then you just have to select the parameter you wish to assign a control so a dialog box open, then move the the knob or slider or press the button on your midi controller, that you wish to assign to the applications parameter, until you see the applications parameter respond.
In the mentioned dialog box in Arturias application you also can see which midi cc it allready have assigned, if it has a parameter assigned. Some parameters has allready a midi cc assigned according to generel midi mapping for certain controls.
You can find many midi cc implementation list on the web. Lists like this:
http://www.nortonmusic.com/midi_cc.htmlYou'll find that many parameters that are mapped and used in applications and hardware still stand on this.
When you assign midi CC to something like a next or previous preset button, then i suggest you use a undefined midi CC number.
With automap I mean that it automatically maps to the right parameters on the vsts, or something like automap from novation.
It doesnt seem to map anything automatically with the other vsts other than arturia that i tried.
Keylab MKII does'nt automap to other manufactors applications.
Keylab has the speciel relationship with Arturias applications, that the Analog Lab integration (that's pre mapped), and the Browse preset settings offer.
Novations last top controller SL MKIII also did'nt have automap like my SL MKII have. Still with that kind of automap it depended on if the manufactors created automaps layouts,as the automapping otherwise is quite random. I have allways needed to create layouts my self to get some order. But i still think that in example the many pages is good - or was, as Novation say it's not needed anymore.
Native instruments have the NKS system, but that also depend on the manufactors or your own layouts. It's not a automap as such.
Perhaps in the future with midi 2.0 this will change.
