Hey !
Even if I spend too much time in the algorithm’s realm, I’m still attached to good old traditional instruments made of wood and other outdated physical materials 
!
And I don’t doubt those who also do on this forum spend a lot of time piously working along they’re old friend : the metronome 
.
So here’s a little metronome interface you might like to work with :
The main idea is to provide a configurable piano roll to get more versatility than the ‘tic - tac - tac’ digital metronomes offer.
2 octaves range (starting from the fifth of the scale), tunable, 7 western modes, 1 - 16 steps.
There’s a simple ‘BPM rule’ algorithm that allows to increase the BPM by X every Nth cycle.
Current state of the soft can be saved as a preset to be loaded back later.
You can download it from here.
Don’t forget : relaxation is the key,
