Hey all just want to point out that beta version 5.1.0 is out and has Expression pedal control as well as MIDI filtering. Read more about the major expansions also available in the current live version 5.0.3. EXP control has been working since version 5.0.3.
The wheel is the best option here, in version 5.0.x and later the Aeros buttons are not used to scroll through songs one by one but you can still do so via MIDI
