MadMapper 6.0.1 not working with Focusrite Scarlett 18i20
Posted: Tue Nov 25, 2025 11:51 pm
I am desperately trying to get MadMapper 6.0.1 to work with my Focusrite Scarlett 18i20 audio interface before a big show I have planned for this weekend.
I am on MacOS Tahoe 26.1. My Scarlett works fine with MadMapper 5.7.1. When I select the Scarlett as my output in MM 6.0.1, and I drag a simple movie with audio onto the stage, and enable Audio checkbox, the movie freezes. In Audio preferences, in the Audio Data window, it reports this:
>Active Audio Input device: Focusrite: Scarlett 18i20 4th Gen
Status: Running
26 audio channels
Opened with 26 audio channels
Sample rate: 44100Hz
Mixdown level: 0
Channel 0 level: 0
Channel 1 level: 0
Channel 2 level: 0
[...]
Channel 25 level: 0
Active Audio Output device: Focusrite: Scarlett 18i20 4th Gen
Status: Failed to start
Is this a bug? Anything I can do to troubleshoot on my side? I updated Focusrite driver to latest version, rebooted, tested the interface with Ableton Live and other software. I can't think of anything else to do and I'm worried this is a bug on MadMapper's side.
I have a performance that makes extensive use of the new Timelines feature so I am worried that I am in big trouble if I can't get this working before Friday. Help!
