At this time there is a bug in Braaass that prevents you from keeping the midi configuration in memory. Fortunatly with Unify. there is a way to get around this issue.
With this layout you can control the Braaass plugin even if you do not play a keyboard. The chords section that we open by touching the Mididesigner logo allows you to transmit chords without touching a keyboard. Thanks to JKHiser for his inspiration.
If you use Unify from PluginGuru (https://www.pluginguru.com/products/unify-standard/), you can control also the Key, Speed and Sync parameters. Just drag the preset in your Unify.
Enjoy!
