How to control Flex AHDSR Decay time with Velocity?

[dannytaurus]

How do I control a Flex AHDSR module's decay time with note velocity?

With a regular AHDSR it's easily done by adding Velocity Modulator in the Module Tree, but the Flex AHDSR doesn't expose modulation slots for Attack Time, Decay Time, etc.

@dannytaurus You could script it, but the lack of modulation slots is a bummer

@David-Healey Great, thanks. I didn't realise it was okay to set attributes like that in the noteOn callback. Proper noob!

[David Healey]

@dannytaurus Yeah it's fine, but I wouldn't do it from the Interface script in a real project. That script should be deferred. Add another script (midi processor) for this kind of thing.

[dannytaurus]

@David-Healey So in general, you defer the main interface script and not use the noteOn/Off/etc callbacks at all? And put all MIDI stuff in separate, non-deferred MIDI processors?

Still wrapping may head around the way scripts are compiled at export.

[David Healey]

@dannytaurus said in How to control Flex AHDSR Decay time with Velocity?:

not use the noteOn/Off/etc callbacks at all?

I use them when I have something on the UI that is affected by note events, such as keyswitches to change articulation and updating that visually on the UI.

Interface script for non-realtime.
Separate processors for individual realtime tasks.

If you always defer your Interface script by default, which I think is a good habit, HISE will give you an error if you accidentality try to do any realtime stuff in it.

@dannytaurus
You could create a velocity modulator in the GlobalModulatorContainer and give the UI button that controls your envelope a matrixTargetId. Then you can do it via the modulation system.

[dannytaurus]

@Oli-Ullmann Thanks. I looked at the GlobalModulationContainer. I haven't used one yet so might be a time to try it, however I ended up getting what I needed with a simple TableEnvelope. It gives me great control over the curves.
