This is what musicians care about. We don’t give a rat’s ass about fancy LED colours, iPhone synchs, beats etc. (this is for kids and bedroom musicians who practice the instrument once a week if their mom/wife is pleased with their school grades/salary). We need perfect tempos and time singnatures to play along. Period. Nothing else really matters.
Thanks for the great comment - I merge it with the tempo changes feature since we would likely develop all this together!
