I modified Jan Ostmans Solina code so that it can be used with GRAINS. I use the "Hairless MIDI to Serial Bridge" (https://projectgus.github.io/hairless-midiserial/) which enables me to use a MIDI keyboard to play the GRAINS strings module:
It already sounds good without effects. But it sounds just great when you use a Phaser. In my video I use VCV Rack as DAW and I use the VCV Host FX module with a VST Plugin. But the AE Modular Phaser module is now on my wishlist
The code can be found on Github: github.com/duddex/GRAINS-Strings This is still work in progress. I have some difficulties because sometimes the notes don't stop. And the control knobs P1, P2, P3 should modify the envelope and modulation. They don't work yet. But I already had a lot of fun with the module.
