Transpose Poly Pressure

Hi guys!,

I have recorded many MIDI parts with Poly Pressure (using Hydrasynth).
The poly pressure is correctly recorded into the correct pitches, but any attempt to transpose the notes, leaves the poly pressure data in the original pitches :sob:.

Does anyone knows how can I transpose the notes with/or the poly pressure?
Is it possible maybe using the logical editor?, can anyone help on how to go about that?

Here is an screenshot just for reference. Some random note PP assigned to C3. But I want to transpose all the notes; copy pasting one by one is definitely not an option :wink:

Iā€™m in total love with polyphonic AT/PP, and also considering getting into the PolyBrute 12, so this is gonna be an everyday problem :confused:

Appreciate any help!

Just if anyone is interested, I ended with this for now, but would love to know if there is a better way.

I think your approach is the right one and Iā€™m hard pressed to think of a better way than what youā€™ve done.


Polypressure is a weird concept and MIDI message.

The raw MIDI message is a lot like a CC:

  • there are 127 CCs, that impact everything on the sound processing device, including all of the notes.
  • polypressure is a bit like having a single CC for every note

polypressure could also done by having 127 mod wheels or 127 knobs or 127 faders. But of course, that wouldnā€™t lend itself to playing live in the same way as having it on a keyboard or drum pad.

So you could do wild stuff, like having polypressure change the cutoff frequency for some notes, while it would change the attack time of the sound made by other notes.

And just like a CC value stays ā€œactiveā€, even when thereā€™s no single note being played or any other sound happening, polypressure also stays ā€œactiveā€ without any notes happening.

A single polypressure event for note 60 at the beginning of the song could stay valid for an entire song for whenever note 60 gets played. ā€“ Of course that wouldnā€™t normally be happening from a keyboard or drum pad, since they send polypressure value 0 when letting go of a key or pad. But it most certainly could be programmed in Cubase. Or someone invents a latch function for polypressure on keyboards or drumpads.

Itā€™s entirely up to the sound making (or manipulation) device to determine what do do with those polypressure events. So a fancy soft synth could have truly wild implementations.

As polypressure keyboards seem to be gaining in popularity these days, Iā€™m looking forward to some innovative synth implementations.

And potentially in FX modules, too, because arguably thereā€™s a whole world of note aware audio FX to be explored beyond what weā€™ve seen so far.

Have you checked if anything changes when using Note Expression? Maybe you get lucky and you can carry the Poly Pressure data together with the note event?

I just gave it a try, but it appears to have the same issue. Once the pitch is changed, the PP does not apply to the note anymore.

I would at least expect it to work similarly as to when ā€œAuto Select Controllersā€ is enabled.
In the same way you can move CC left and right when selected, it would make sense to apply the same idea vertically.

In the end PP, is still a contineous controller as any other CC, it just carries with it the value of the pitch associated with the event (which would need to be transposed).

Are you sure? I checked earlier today and the Poly Pressure note expression was following the note. I guess it must be specific to how this poly pressure is recorded. I was just drawing by hand.
