Redesign tapping
Tapping doesn't work very well for the moment.
It could be improved by:
- using a tap history to smooth the BPM out
- ruling out the first tap as it can't be used alone
- ruling out taps older than a given time frame
- giving visual feedback about the remaining time to tap
Maybe the visual feedback could replace the BPM display while the we are in the available tapping time frame.
