Thanks for the tips! Yes, sometimes I render highly intensive synth tracks to audio to save CPU usage. However, I often receive requests from customers to modify the tune or create alternative melodies. Because of this, I frequently need to reopen the MIDI data and tweak it to meet their requests, which is why I prefer not to render audio. In terms of VSTs, the drum and orchestral tones come from Kontakt libraries, while most of the melody tunes are crafted using Serum and Pigments synthesizers.
