I try to do quite often something similar with Scaler Chords and Spitfire instruments. However, I don’t do it so good as you do.
I use Reaper with ReaLearn to control CC with my MIDI controllers, KORG NanoKontrol2 and AKAI MPD 218. The former is used for expression, dynamic, reverb and vibrato, and the latter to select on the fly different articulations.
I like that, sounds great, just goes to show how versatile Scaler can be. I to have been experimenting with classical themes but nothing as good as this, my effort of (for want of a better title) “Epic trailer” can be heard at Listen to Epic Trailer by Sprocker Rock on #SoundCloud https://soundcloud.app.goo.gl/QAtXc.
Recently, I started publishing on Youtube. My first tries (of any kind of music) with photos - mine or form Unsplash. My last published orchestral song, based on Scaler progressions, is called On the Banks of the Quiet River.
