bump!!

Sorry for no replies. I'm afraid there is just no simple convenient answer to it. Reaper has no direct offline conversion between automation envelopes and MIDI CC or vice versa.

A workaround you could try is to copy the points of that envelope to an (empty) envelope that controls your desired target CC in ReaControlMIDI (or another MIDI plugin that lets you spit out the CC you need with an automateable slider). Then record the MIDI output of that track in realtime.

I never needed to do that yet, so I don't know how accurate the result will be.

thanks Gofer,

try but not work

I will make a function request.

may be a good idea?

Maybe. or a specialist JS FX might be simpler.

I would like to ask a few things:
-- where did the Automation Envelope come from?
-- what was it automating?
-- what do you want to control with the CC messages?

[planetnine]

Seem to remember a query v recently asking for the other way round ie automation from CC lane; I think the answer there was ReaControlMIDI.

I did a quick test of the workaround via ReaControlMIDI and it seems to work. Still don't know how accurate it is. Of course resolution is down to 128 steps (I figure this can be upped to 14bit by using combined MSB/LSB CC pairs in ReaControlMIDI, but they are ugly to edit, as they are using two CC lanes in the editors and it's not certain your destiny device makes use of the 14bit at all).

Here is what I did:

- select and copy all points of the original envelope
- create a track with ReaControlMIDI
- create an envelope lane with my target CC (I used CC74, cutoff freq)
- paste the envelope points of the original envelope into the CC74 lane
- set the target track to "Record: Output (MIDI)" and arm for recording
- start recording

=> the result was an item with CC74 events recorded following the envelope



It also works using the original track and inserting RCM right there, but might be a bit confusing if there are already items existing.

Coming soon

Installation:
-- download the attachment, remove the .txt extension
-- put the file in (a sub-folder) in your App Data/REAPER/Effects folder

// ================================================== ======
// This JS FX converts up to 4 Automation envelopes to MIDI CC messages

// Load the FX onto a track
// Show the automation lanes for the CC_value parameters
// Copy / create an automation envelope for each lane
// Set the desired CC numbers and MIDI channel in the FX
// Record the MIDI output of the FX
//
// ================================================== ======

Now increase the playback rate; some way to avoid real time?. - just kidding...or perhaps not...

Thanks, sorry for my bad English.

REAPER es fabuloso.

[DarkStar]

You're welcome - I hope it encourages you into the world of JS FX development.

As for rate changes, stretch or contract the recorded MIDI clip.

[ProFête]

thank alot for your script

i don't know why but reacontrolmidi overload my hardware (same in raw mode) but your script don't

[mschnell]

Anyway, generating a bunch of Midi messages should not use a considerable amount of CPU.

Put an empty MIDI item on the track with ReaControlMIDI (or the JS) and "Apply Track FX..." to do it faster than playback.

Parameter Link might be faster/less messy than copying Automation, but only works on the same track.

Why are we doing this again?

Oh yeah! Was gonna mention there is at least a couple actions/scripts out there...
