Fugue Machine has received a bunch of updates in the last week; following the inclusion of iPhone and AUv3 support. Today's update now lets you set per-playhead MIDI channel destinations when used in AUv3 hosts, as you can when Fugue Machine is used standalone.

What's new in Fugue Machine v1.5.3:

Fugue Machine 1.5 — iPhone support, AUv3 support, more scales, piano roll gesture improvements, and more! See 1.5.0 Version History for more info.

1.5.3 CHANGES
MIDI OUTPUT SETTINGS (AU)
Similar to the standalone app, you can now set per-playhead MIDI channel in the AU. For more details, in the AU, go to More Menu > Settings.

NOTE-LENGTH CHANGE DETECTION
Improved one-finger note-length change detection. Much better at higher zooms now. As before, simply pan-right at a note's right-edge to change its length.

CHANGED AU NAME
The AU is now simply named 'Fugue Machine'. Some users were having trouble finding the previous name, 'FM.au'. Please note, depending on your AU host, this may cause issues. If you experience any issues, simply open the Fugue Machine standalone app and go back to your AU host. If that doesn't work, try restarting your iPad.
