The DRE4MTR4CK is a simple and intuitive Polyrhythmic Organic Melody
Progression Sequencer in 12HP Eurorack format.
Painstakingly fabricated by hand in the USA.
It has 4 steps, and 4 tracks of chromatic scale note quantization.
Each track has its own clock input, clock output, and Pitch CV output.
This way you can send pitch data to four different VCOs.

Unused clock inputs are multed from input 1.
Interrupt clocking for a track by inserting a floating patchcord.
Manually trigger a track step using the TRIG buttons.
Intuitively build evolving chords or poly-rhythmic note progressions.
Simple pattern modes and Octave transpose for each track provide
  seemingly endless note progression.
Mix things up with Step reset and track data Rotate to re-circulate
  CVs among your VCOs.
16 non-volatile memories for program note data Storage/Recall.
