Keyswitch extension

[jpcima]

Hello, this is a request for a keyswitch extension.
It's functionality usually found in samplers, which makes certain keys of midi keyboards switch to a different timbral variation.

The keyswitches can be packed together in groups, which are usually adjacent keys with a same color.

The purpose of the extension would be to expose the keyswitchs to a host, such that they can appear on a virtual keyboard, and/or have the switch names appear on the notes of a piano roll. (similar to clap_plugin_note_name)

This exists in vst3, with a severely lacking documentation.
https://steinbergmedia.github.io/vst3_doc/vstinterfaces/classSteinberg_1_1Vst_1_1IKeyswitchController.html

In essence, I believe it should be

• list of keyswitches, having a name, and the key + channel + port as identifier
• keyswitches can optionally refer to a keyswitch group that contains them
• keyswitch group can have a name
• plugin can invoke host's changed to reload the switches

Hi,
Thank you for your submission.
Just to let you know, I'll take a look at it later as I'm currently trying to finish what I consider the core design and fundamental extensions.
Cheers,
Alex.

Hi,
I actually have no interest myself in this extension at the moment. Does anyone wants to look into it and make a PR for it?
Thanks,
Alex

Is there any consideration for such a feature now that the core is done?

Also I skimmed through some docs and I'd like to ask if there is any way in CLAP to query midi events or audio (in a track) ahead-of-time. This would allow virtual instruments to automatically play various expressions in a smart way depending on note context (is note surrounded by shorts, does it lead to another long note, does this part look like a glissando...) and adjust the playing style or samples in a way a real player would. Technically this could be done by hacking around the transport control but that is a very inefficient and dirty way to do it.
