Is there any chance of updating the editor so we can transpose. Like a select all function. This would probably be my biggest wish so that I can change keys with beats that have bass 
Hey there,
Unfortunately there is currently a stall in improvements to version 1.x.x of the BBM, we are going to be making a BBM 2.0 however, and once the MIDI editor is being made, this can be considered.
We apologize for any inconvenience and hope to have good news soon!
Thanks for the suggestion
