[FR] adding cue/recall for specific effect slider configurations

[nulltrope]

It would be really neat if there was some way to "save" the current state of your effect(s) sliders etc. into some persisted memory so it can be quickly recalled/switched to later, ideally via a hotkey/MIDI control command (if using VST). For example, OsciStudio lets you do this via it's "Cue" functionality, where you can save a large number of configurations to various cues to immediately be switched to, or even a way to smoothly "fade" or transition between cues.

This would especially be useful for live coding scenarios, where you have some presets ready to go and can quickly switch between them on the fly.

My current workaround when using a VST in Bitwig is to just save the entire VST state as a preset but switching between presets requires (to my knowledge) re-creating the entire Plugin Device in Bitwig to change to it. Having something native would be way more flexible!

If you're open to contributions, i'm happy to take a stab at this as well, just need to familiarize myself with the codebase/JUCE. If you have any pointers to where I should get started in terms of files, let me know :)

+1 to this idea.

Also that's a neat workaround. I wonder if I can do something similar through Ableton.

On a semi-related note: I started working on a extremely very janky, untested (programmatically), osci-render-midi version of this plugin last night. I also wanted something like this + to be able to record notes & play back in my DAW. Sorta works, but also sorta crashes sometimes during save/load. Crashing may be due to my laptop offloading files though.. Also I don't know if I've broken the normal audio plugin in my branch, since I've only been dev building the new midi-instrument setup 😅 I too am new to JUCE and the codebase. Also haven't used C++ in years lol, so my code is certainly not prod-ready.

(little demo video of me using it as instrument, loading in a previously-saved preset, creating a new one and loading it, plus using the DAWs sequencing to play as instrument)

@inFocus7 what do you mean by recording notes and playing back in your DAW? Just checking you are aware of the MIDI functionality already in osci-render by clicking on MIDI settings and enabling MIDI?

Ahh, after a bit more testing I see what happened on my rack setup -- at least when I thought it wasn't supported. I believe I had an instrument/midi plugin loaded on my rack; since the plugin is an effect plugin, the MIDI was routed towards the instrument, instead of osci-render during recording 🤦🏼

I'll remove my local updates that creates the midi/instrument plugin version, but shall keep my local setup for presets -- unless that's actually supported through some lua loading 😅.

The preset idea still is really great. I stripped off the portion of my code that handled midi stuff and kept the preset handling (ref). There are still some bugs needing resolving though.
