req: eel for input of env point in various formats

[babag]

i'm working with a template for which i have reacomp set up as a side-chain. i want to be able to adjust the envelopes for its parameters by dropping in a new point and entering a value for it. the placing of a point is fine but there is an issue with setting the values. reaper sets envelopes in its own numerical system but the reacomp parameters are displayed (and thought of by probably just about all users) in varying formats:

threshold = db
precomp, attack, release = ms
ratio = i don't know what (db?)
lowpass/hipass = hz

other plugs my have others. i could really use a simple script that would set a point's value based on each of these types. could be one script with choices, could be a series. as a series they might integrate better into custom actions.

anyway, any help on this would be much appreciated. maybe such already exists?

thanks,

This is actually quite difficult, but seems to be possible:

Set formatted value for envelope point under mouse cursor



It's not working yet - I'll try to post something this weekend

I was looking at this after seing babag post, but didn't find how to set from formatted value, but it doesn't seems possible...

I wanted to update my script from ReaScript: Set/Offset selected envelope points values with this feature. :P

Let me know if you find a way !

[babag]

hmm. i'd have expected there'd be a formula to translate each value type to/from reaper format. didn't mean to open a can of worms!

X-Raym, I'll let you know
(I'm not 100% sure if it's possible to set from formatted value...)

VST3 actually has native support for converting a formatted value back to a normalized parameter value, so it should work automatically for any VST3, assuming the plugin supports it.

Additionally, the REAPER extensions to VST2 support this via effString2Parameter. Some 3rd party plugin developers support these extensions (Voxengo for example, I think). Somewhat embarrassingly, among REAPER's built-in plugins, only ReaEQ, ReaSurround, and ReaControlMIDI support the 2-way extension. We'll add support in ReaComp as well.

@schwa
thanks for the infos !

is there any way to make this work for any kind of plugins (js, au etc...) ? maybe via a function in ReaScript API ?

[babag]

what are the formula for the various conversions? are they listed anywhere?

thanks,
