Thanks so much for the feedback! I considered just making one really high-quality track, but opted to go for a larger OST to test myself and see if I could come up with a 'complete' sounding OST in a limited timeframe. Regarding the first track, yeah I could definitely see it being expanded. I'm a huge fan of Bach's Preludes and Fugues, and building upon the foundation I have with a multi-voice composition could be really cool, as you mentioned. I didn't know much about partimenti, so thanks for bringing it up! Do you know any good textbooks or databases I could use to learn more about it?
