Writing Parameter Modulation (via sidechain) to envelopes

[IDDQDSound]

Hello!

I wish there was a way to write parameter modulation onto the envelope of the parameter being controlled. Let's say I'm controlling the rate of my delay using the incoming audio signal via side-chain. Works well!

What I'd love to do though, is to then be able to set my automation mode to write, and have that parameter's values written to the envelope lane as if I was tweaking the knob manually. This would be awesome as it'll allow you to generate envelopes very quickly, and then disable the parameter modulation and fine-tune the envelope.

There are workarounds if the param is linked or modulated via LFO but if you're modulating with audio signal, there's not currently a way of writing that afaik.

For some reason I thought this is already possible. Even if you touch a parameter, it still won't record any automation. Yes, it makes perfect sense.

I just thought of a workaround but it takes forever:
-JS Loudness Meter on the audio signal controlling the Parameter.
-Have it write out the loudness reading as volume envelope.
-Draw Automation item around the envelope. Drag it to the other parameter.
-Adjust the baseline & amplitude until desired result.

This work alright but takes too long and if you're limiting the min & max volume, you need a double gate set-up to write that to JS Loudness Meter, and of course, you get less control since you don't have attack and release. Best you can do is select all envelope points and adjust their curve. Much easier if this arming and writing them was possible

Did you try latch mode? Not sure what is not working? Latch mode, touch the parameter you linked to once (so automation item is generated), and it writes here.

I tried write mode earlier and it didn't work. It did now! Thanks and sorry! The reason I got tripped up is that when you're in write/latch/touch/latch preview and you physically move a parameter, the parameter becomes armed and visible. With Param Mod this doesn't happen, but if you manually arm and make the envelope visible it does write it. My bad

Interesting idea! Still the FR is relevant.

And if you want to leave writing further, stop, play.

Probably there are some secret Reaper settings, where you could tell if Reaper should write even to non-visible envelopes, not sure, but could be more than 50% I guess.

UPDATE:
You could try this: Preferences, Automation, Hidden envelopes: Allow writing automation (checked)

Can you share a few more ideas what could be modulated using live audio signal, like playing guitar/bass as in your case for example?
- delay rate
... ?

This thread can get a collection of cool ideas for live-audio-modulating as well, if Reaper users participate. And we can check each time, best way of routing or using Reaper possibilities how it could be done using "best possible approaches", currently. You never know if tomorrow some magic script will appear, doing all this automatically for you.
