Hi @beatssparks welcome to the forum. Sorry hear you are having trouble with Scaler 3. There is a bug which is currently being addressed regarding the tempo of MIDI Capture, which is currently fixed to 120 bpm. This may be what is causing your frustrations.
We have this error logged in the known issues page, and do plan to have it resolved in the upcoming Scaler 3.1 update due later this month. Apologies for the inconvenience.
You can confirm if this is the bug you are experiencing by setting your tempo to 120 bpm and seeing if the MIDI Capture results look correct.
