Is there a way to use aftertouch in OPMT?

Nahkranoth · May 28, 2009, 15:04:17

Just as the topic says, for example I want to pass it to VSTis like MIDI CC, or volume or whatever. I would like to know, and of course use it. As I understand it's not a MIDI CC.

Aftertouch? Shouldn't that be calculated from the volume the current note has?

Maybe this could clarify: http://www.midi.org/techspecs/midimessages.php

The plugin must support aftertouch too, and if thats not the case, it will not work at all.

If it does support aftertouch, it might also support custom mappings, making it possible to use midi CC's to control that parameter seperatelly.

I don't know about OPMT, but in OMPT, in addition to possible ways given by plugs, I'm not aware of any other way than sending the message using custom macro, and that doesn't seem like real option. But anyway in case you want to test, I think the custom macro should have value AKnnaa, where nn is the key(note) number in hex and aa is the pressure parameter in hex. If you want to control either of the parameters with the macro parameter, replace aa(or nn) with z.
For example Z70 used in pattern under active macro AK40z would send message AK4070.

I guess not, but it would be great if volume commands without a note changed aftertouch value of the instrument.

Oh, gawd! Or further confuse me

But thanks for this, I remember some time ago finding some table like that, but I couldn't find it again.

Thanks for this mantra, I will try

But aftertouch (aka "expression") is based on the velocity (how hard you touch the piano for example) of the note, so this should actually be realized through velocity.

Isn't "expression" for pedals? And aftertouch is for pressure, not velocity.

Jeez, had a fight with my wife, so haven't tried if it works yet :oops:
Have anyone tried this, lads?

Shyte, it's not working. Even if it would, it will be a PITA to use it the way Relabsoluness told. So I'm off to make a request!
