I needed to use the KeyMidi Extra but I couldn't figure out why I wasn't getting any sound in my project. I foolishly realized that I wasn't in the range of midi. I decided to add the following features:
- Clips to the range of midi.
- Shows what octave you're in.
- Tells you when you need to go up or down if you're out of range.
Simple features that might save you the embarrassment I endured.
