Analog Drum Machine

This module currently being produced by Jeff Lee in Toronto, Canada. Due to be released some time in 2017 if all goes to plan.

808, a classic drum machine for Eurorack

The System80 808 is a 16 voice analogue drum machine reformatted into a 60 HP Eurorack module. It couples 16 analogue drum voices to an enhanced step sequencer. The drum circuits are exact clones of the original 808 schematics using the same semiconductors wherever possible. All operational amplifiers and bipolar transistors are the same as in the original. Each drum voice was carefully compared to two original 808s and small adjustments were made to tune each circuit to match the 35 year-old original reference machines.
