Have you made one that can either step edit or record say an 8 bar pattern?

Documentation:
This application is controlled by both touch/click and keyboard. The higher a key is, the lower its velocity (making, for example, the quietest Kick trigger the letter Q and the loudest trigger the letter Z). Three stages of velocity are available for each pad. I started developing this drum pad as a mobile-exclusive application until I realized it could be more useful with a keyboard for velocity control.
Controls:
Q A Z: Kick
W S X: Clap
E D C: Snare
R F V: Crash
T G B: Open Hi Hat
Y H N: Closed Hi Hat
U J M: Rim
I K ,: Tom
O L .: Clave
1 2 3: Cowbell
Bonus: 909 Edition
