External MIDI controller and synth

[dwrae]

Thanks for your extensive explanation of the problem. Please go into the app's preferences (More -> Preferences) and scroll up/down to 'MIDI thru'. Here you can route MIDI inputs to MIDI outputs. There is a slight chance that changing the setting causes the app to crash since there is still a bug lurking in there, but please try and let us know if it works.

I'd also be interested to hear what happens if you press the 'Next' button 3 times from the main screen. Do you end up back on the main (time line) screen or does it display mixer hardware controls of your Steinberg?
