You’ll be excited to know that Noteflight now offers the option to open your score in Soundtrap, the amazing online DAW! That gives you immediate access to a lot of the things requested here.
Just go to Export and choose “Open in Soundtrap” (requires a Soundtrap account).Anonymous commented
I agree. Synthesizers are among the greats of electronic instruments, and it would be greater if Noteflight would support synthesizer parts.
