Blue Melody 2.6 is here
The biggest update since launch, and it’s free for every subscriber.
Copy and paste with FL Studio. Select notes in Blue Melody, press Ctrl+C, then Shift+Ctrl+V in FL’s piano roll. Going the other way, use FL’s Copy to MIDI clipboard and press Ctrl+V in Blue Melody. You can also drop a .mid file straight onto the roll, in any version of FL.
Instrument Link. Pick an instrument from your Channel Rack and your pattern plays through it, with no MIDI routing to set up.
Learn. A built-in tutor and composer for when you want to know why something works. Turn on Blue Melody AI to ask questions and get melody and chord ideas you can preview before they touch your roll. It’s optional and stays off until you switch it on.
Older FL Studio. Blue Melody runs in any 64-bit FL that hosts VST3, and its FL helpers now work back to FL 20.7.
To update, download the new installer from your Lemon Squeezy order email or My Orders, run it, then rescan plugins in FL Studio.
