Not a bug but a featutre ?

But to let those know that might be affected.
seemingly since some version of Reaper's this has changed, and it broke my live setup, so that I needed to modify a JSFX of mine.

Topic: Midi Link (CC) to plugin parameter.

Former behavior:
When loading the project, the parameter was used as stored in the RPP file. It only was modified with the first Midi CC that was detected on the track.

Current behavior:
When loading the project, the Midi Link to the plugin parameter hits at once, even if no Midi CC had been received yet, overriding the default setting from the RPP file. In my tests the Value "assumed" for the CC status seems to be Zero.

Testing:

I have a JSFX that features a slider and sends out a CC when the slider is moved, but not when starting the project. This CC is acknowledged by a ReaEQ parameter. While the EQ was in default state after starting the project, now the parameter is forced to zero. I needed to modify the JSFX so that a CC is sent when starting the project.

Hmm can you post a minimal test project+jsfx to demonstrate this?

mschnell · 03-04-2021, 11:31 AM

I found the issue in my huge live project. And it definitively changed some weeks ago.

I'll do a test in a new small project later this day.

What is the desired behavior ? Should a Midi Link only do anything when a Midi messages arrives, or should it already be "active" at Reaper start ?

(BTW did yout see the fork done with OSCIIBot ? Seems a very interesting issue, and an optimized version in the trunk might be appropriate. )

IIRC midi link should only happen on incoming MIDI events, but perhaps there's something sending MIDI events (e.g. pitch-reset on playback start, etc).

This seemingly is not the case.

Test project below.

The JSFX "Slider and Midi CC" (available in ReaPack) is deactivated and hence does not send Midi messages
The ReaEQ Gain is set to 0 dB (corresponding to CC 64 with the default Midi Link)

If you start the project the gain is set to -inf (corresponding to CC 0 with the default Midi Link) nonetheless.
You can activate "Slider and Midi CC" and move the gain via the slider just fine (and see the midi messages in the ReaMidiControl Log).
Saving and then starting the project with the JSFX enabled results in the JSFX sending a message according to its saved state and hence correct gain.

Ah thanks, I see. Yeah, that's the way it has always worked. Perhaps it would be useful as an option, to only change the state when a CC comes in...

Funny. I needed to add some code in a JSFX in my setup to make this work (i. e. use the state saved in the project file on project start) again. Unfortunately I don't remember when exactly this stopped working, but I am sure that it did work fine when I created this setup some years ago, otherwise I would not have been starting using it.

MIDI CC link was added in 5.11, I tested that version and it behaves the same... It’s possible that there’s some version in between where that changed, I guess, but i haven’t found it.

Learn of course has the other behavior... the CC link is designed to be used with midi items etc, which chase and thus provide a way of automating via MIDI...

mschnell · 03-06-2021, 11:52 AM

In a live setup - always in stop mode - chasing is obviously not done.

Of course I should have been more careful and send the CC after start up. Thanks for listening....
