Variation by Note /Pitch Length (Envelope Filter sorta..... on Note Length)

Vmusic

I am looking for a AUV3 plugin that measures (pun intended) the length of a the same pitch and provides or sends out a MIDI CC message based on the length pitch, and some settings of course.

EXAMPLE: I play a C note, and let's say I hold out this note for 4 beats (however long that happens to be); the plugin starts sending out MIDI CC values 1 - 127 and for this example, in the settings 4 beats is set to go up to 64, so it sends MIDI CC values 1 - 64. The second or subsecond the plugin tracks a new note or pitch, "the clock is running" so to speak.

Then after 4 beats, I change the note to a D note. Once the plugin senses and tracks this new note or new pitch, it starts all over again sending out MIDI CC values from 1 to .... however long I play this new note, based on the settings. This time I only play this note as a 1/4 note, so again based on the settings described above it sends out values 1-16.

As soon as the plugin tracks a new /different note or pitch, it starts "running" and starts to send out MIDI CC values, starting from 1 (or zero ..... whatever) based on the settings, and the BPM in the host.

Certainly - the plugin doesn't know in advance - how long I will play a note; but it does know when I start a new note or pitch, and it DOES KNOW based on the settings, and based on the current BPM, what rate to start sending MIDI CC messages out at. [[ is this true? it seems possible, correct? ]]

The output from can be used to control other fx plugins. For example: especially modulation fx, where if I hold a note out longer, where longer is relative to other notes, but also taking into account the settings and the BPM - then I would get MORE modulation fx (or more wet mix vs dry mix).

Again to follow up in my example; in my settings 127 (or the max) is for 8 beats. So IF I play a single note, or a single pitch CONTINUOUSLY for 8 beats, the plugin will send out all the way to 127. IF I play a whole note, or play the same pitch CONTINUOUSLY for 4 beats, then it sends all the way up to 64 as I get to the end of the the 4 beats, etc.

Is there anything like this???

Not​​ sure but you would need to be only playing one note at a time for this to work. It sounds to me like just picking an mpe instrument paired with an MPE controller would be a better solution, allowing you to assign pressure or y axis movement or whatever to do the modulation you want to do here.

One way is with Drambo using the Graphic Envelope and a Midi CC Generator. You'd have to rig up something to block the CC messages on note-off though. I'm sure one of the drambo experts could help with that.

If you don't want to involve Drambo, there's a Mozaic script that's fairly close to what you want, though it's not tied to the host BPM. You seem like you know something about coding, so you might be able to adapt it to your purpose. It triggers an ADSR envelope on receipt of a midi note. You're only interested in the Attack phase of that envelope, so you'd set the level and the attack time, turning the others to zero.

I knew it..... I have Drambo!! (don't know how to use it)

I believe that when you say "play a note", you don't mean send a note from a keyboard, you actually mean play a note on your violin. So the first problem will be detecting notes of different pitches in an audio stream. You may have already tried one of those "guitar to MIDI" apps. That could be a front end to a script that generates a CC ramp from note on to note off.

I was assuming "play a note" meant play a midi note. If not ...

If not, then FAC Envolver is one choice that might work, though not tempo synced. [edit] nvm 2 seconds max duration is probably not enough.

Drambo could do it with addition of a transient detector module to generate the envelope trigger.
