Here's my updated release trigger script. I've added a mute button so that release triggers can be disabled. I've also added a legato button: when this is enabled release triggers won't be played for each note of a legato phrase, they will only play when the last key is lifted.

Aha that's interesting, I tried with longer note delays and got stuck notes - now I know why :)

Nice. Another way using a Slider as scrollbar:

Although you could add the scrollbar logic also to the viewport ScriptPanel (and also support mouse wheel scrolling).

Yeah, I had to get another server for the forum, but I'll migrate back to my original hoster and resolve this DNS mess soon.

I thought emails worked (I am using a Gmail account for the mails), but I'll investigate.

Everything you mentioned could be also changed via scripts. I would recommend a JSON file with all instrument definitions which contains the parameters for all envelopes, sample maps / filters, etc.

Another possibility is to embed everything into your app. In this case you can actually swap out the whole preset on the C++ side by calling MainController::loadPreset().

To purge a whole sampler is pretty simple (but impossible to know until there is some documentation):

Sampler = Synth.getChildSynth("Sampler"); Sampler.setAttribute(12, 1); // 12 is the index for purging attribute and '1' is purged ('0' is normal and '2' is disabled)

I wouldn't call this in a MIDI callback because it blocks the audio processing, but for control callbacks it is perfectly fine.

You can also purge selected samples within a sampler. This procedure is a bit more complicated and I'll decide the next blog tutorial to it (you can also automap the samples with these API calls).
