MIDI has no sound

Importing MIDI in Audacity works but there is no sound.

Which version of Audacity? (look in “Audacity menu > About Audacity”).
Which version of MacOS?

Have you installed / configured a MIDI playback device?

See: Missing features - Audacity Support


I just installed sforzando. What do I do next?

Shut down Audacity completely, and restart.

Run it and keep it running BEFORE launching Audacity.

It opens with no “INSTRUMENT” selected - on my Macbook Pro with Catalina I only have TableWarp2 as the available choice - but selcting that and then running Audacity with 2.3.2 or 2.3.3 test RC01 build plays the MIDI just fine.

You may also need to tweak MIDI Devices Preferences to ensure that sforzando is the selected “Device”


I’m using Audacity 2.3.2 on macOS 10.15.1. I use terminal to launch Audacity. I closed Audacity, sforzando and terminal completely before restarting them but still no sound.

Sorry @waxcylinder, didn’t catch your last post. Anyway, it appears sforzando does not have instrument choices suitable for my use and SimpleSynth has not been updated for macOS 10.15. Would linking something like GarageBand be possible?

Isn’t Garageband another stand-alone audio production program? How would you like them linked?

Can you program in Garageband?

Why not do everything in Garageband?
