The GMSN! Pure Sequencer is used for creating melodies, hooks and riffs. The 8 sliders set the note to be played, which can be played in turn, randomly or pendulum (forward, then reverse, then forward, etc). Each step also has a gate out, which could be used to trigger drums or notes on specific beats.
The module can be in run mode, or in pause. In pause mode each step can be selected and adjusted. There is also control over the speed, which can also be controlled by an external CV clock, and a slew control. The range of the sliders can be selected to either 2 or 8 octaves.
The design is based on the same chip used in the Arduino Uno, which means the same code, libraries and IDE can be used. Check out the GMSN! Youtube video for how to upload the code onto the module.
