Rhythm to play along to when transposing or change pitch of play back
When I use the transpose option (I have upgraded to Premium) it would be nice to be able to mute the now out of key music and not hear the generated chords either since they often don't play at the right time, and just have a basic rhythm beat to follow. I'm also a singer besides a guitarist and would like to practice the songs in the right key for my voice and not hear the out of key music but just my guitar and the beat to keep me in tempo with the displayed chords as I play along to the notation. Changing the playback pitch to follow the key change would work even better of course.
Changing the playback pitch is unfortunately impossible in general (we stream from YouTube, for example, so we can only do what their API allows us too). A clicker rhythm, however, would be possible. If enough users ask for this, we will implement it.
Here, I found implementations of your impossible task:
