This is an attempt to emulate some of the "cinema drum" libraries that let you combine various drum loops in sync to create a percussive "epic" soundtrack.
Play notes starting at C2 and up to choose a tom drum pattern. Slider B does the same thing - I just assigned the keys to ones I liked. Below C2 is a bass drum pattern. Above C4 is other percussion. Use the sliders to adjust the patterns as you like. Zone 2 adds an orchestral sound
Sliders :
A- tom brightness
B- choose the rhythm of the toms
C- choose the range of the tom pitches
D- rhythm of the percussion
E- Vary the choice of percussion
