setting pitch bend range for Kontakt

[woggle]

I have a specific compositional problem - I want to smoothly raise the pitch of a note from Kontakt (violin, duduk, whatever) by a semitone over a period of time up to a minute. Add I want to do this for hundreds of notes

However I have had no success finding an easy workflow. In Kontakt I can assign a CC controller to "tune" and then draw an appropriate envelope. But I can find no method (in reaper) to easily ensure the pitch moves only one semitone.

It has been suggested that I go into Kontakt and set(Instrument) Options
PB Range.

But apparently that is not an option in the instruments I want to use (KH Concert Strings for example)

any suggestions?

thanks, woggle

Go to Automation tab on the left side, select your MIDI CC assignment, scale it with From: and To: controls in bottom left to ensure that CC range of 0-127 goes only a semitone up or down.

But I would suggest using host automation instead of MIDI CC instead, since it will provide much more resolution than 128 CC steps.

thanks - I had hoped to lock the automation to an individual item but this does not seem to be possible so I will go down the host automation route. 128 steps is good enough for pitch - that is changes of less than a cent, which is less than discrimination thresholds, but I take your point

If you go in both directions (semitone up AND down), then the changes are more than a cent, because you have 128 steps, but 200 cents in the range...


You can lock the automation to a single item if you use MIDI CCs, though. Your choice.

thanks again, just up a semitone so 128 is fine, I think render to audio then process might be the way to go for this specific problem

MIDI Pitchbend is 14-bit which is 8192 steps, + and - (0-16383).
I do long bends which I want to be more or less smooth, 128 isn't going to do it. YMMV -
But I would not expect a semitone over a whole minute to be smooth at all at that resolution.

So, you can set the Kontakt instrument to have a total range of a semitone if you like and use the pitchbend lane.

[EvilDragon]

That's true. However if the library doesn't have pitch bend modulator set up and is locked for editing, automating the master tune knob is about the only thing you can do...

[jancivil]

Oh huh, yeah I failed to read that
I saw Kontakt & duduk. Which allows you to set it.

I wouldn't use CC in any case, not fine enough. You have answered the question already.

For quick changes they might work. For long bends/slides, yeah, it wouldn't quite work, but host automation would.
