Or... maybe this search for 'aftertouch' from within these forums?

Larry Schaeffer wroteFrom what I've been able to gather searching the forums, it doesn't look like S1 supports poly after-touch. Am I wrong in this assumption?

It's a bit more nuanced, but you are basically right.
Studio One does recognize Polyphonic Key Pressure messages, however it isn't able to record those on Instrument tracks. In other words you can use Polyphonic Key Pressure to play instruments that support it, but you can not record it as musical data to reproduce it within Studio One.
Currently Polyphonic Key Pressure messages can be merely used withing Control Surface configurations.

There where numerous feature requests in the past, one of those can be voted on here: Will Studio One support polyphonic aftertouch?

For the future you could ask yourself if the support of Polyphonic Key Pressure messages shouldn't be incorporated in MPE (Multi Polyphonic Expression) messaging. MPE was initiated by a group of developers (among those: Apple, Linn, Moog, Bitwig, McMillen, Roli, Haken & Madrona) which will probably bring the concept of Polyphonic Key Pressure to a much higher level.

If PreSonus will adapt MPE is impossible to say.

Thanks for the link, niles! Voted!

Thanks also for the MPE pointer. Never heard of it before.
In addition to that approach, I hope that more manufacturers will support CopperLan which is available NOW and comes with high-resolution, bidirectional control out of the box. CopperLan is not only great for controlling (sound) parameters but also for musical data like notes/pitch and expression.

Speaking of the VAXMIDI, I wonder if Studio One can handle 14-bit velocity...?

Just bumping this feature request for V4:

Simply amazed that a serious DAW has this missing, also amazed that there is only 146 votes on it. I notice out there in internetland people talk about sticking or moving to cubase because of this.

Even though I don't need it, voted it up anyway.

I noticed these pricey midi controllers use polyphonic aftertouch.

But I read that it shouldn't matter here:

I got the impression that the OP was basically saying, "we're at 4.1 and we still don't have polyphonic aftertouch, so here's a bump."

Could be right but wasn't the OP.

The OQ (originally quoted - at least in this context)?

You know who I meant...

Doesn't matter. Still no polyphonic aftertouch.

Bump.

Here is hoping for 4.1.3, good gravy. BASIC MIDI

Damn right. Here is to hoping.
Right let's see how this update goes.

I dont think it will ever show up. I could be wrong but Im not
