1/ color the "flat/sharp meter" with "flat side as yellow" and "sharp side as bright red" and "spot on as green"...the large letter name could the scheme follow as well...
2/ include the octave number with the large letter name...
...when recording I use an ipad remote for control and MT does not open in GUI/Cocao mode, but rather in Control, and the computer/monitor maybe thirty feet (aprox.10m) away...sooooo...the visuals would be a great help...
