Granite can create vintage drum machines drum sounds and effects using
both it's built in oscillators and 16bit .wav samples

Granite uses kits each composed of 8 drum presets with the ability to
load/save/copy and paste sounds to create your own kits. Each preset can be sent to one of four stereo out channel and can be part of a choke group. The preset are organized so it's easy to change the sound's name, volume, pan , output channel, choke, and sample.

Each drum preset uses two oscillators each with 12 waveforms or 16 bit
.wav samples (the position played of each sample is controllable with an
envelope so you reverse or time-shift them) , a 12/24 db low/high/band
pass/band reject/ring mod/ comb filter, and frequency & ring modulation.

Each drum preset has it's own decimator & distortion filter to further
alter the sound.

The drum preset's parameters can be controlled using a vari-slope
envelope with upto 16 section and a definable loop position.

Any drum preset's parameters can be controlled using midi commands via
the midi learn function

100 preset and a full manual are included with Granite2,
