SY0.5 Analog drum moduleA faithful 1: 1 recreation of a single channel of the Pearl Syncussion SY 1. The circuit uses all modern versions of original parts (all the opamps are still in production!) and equivalent parts for out of production parts. Operating Instructions Features 10 HP, 20mm Deep Current Draw: +12V 130 mA, 12V 20 mA Output at eurorack levels CV modulation of Decay Time CV modulation of Filter Cutoff CV Modulation of OSC pitch CV input range + 5V Instructions

A faithful 1:1 recreation of a single channel of the Pearl Syncussion SY-1. The circuit uses all modern versions of original parts (all the opamps are still in production!) and equivalent parts for out of production parts.

Operating Instructions

Features

• 10 HP, 20mm Deep
• Current Draw: +12V 130 mA, -12V 20 mA
• Output at eurorack levels
• CV modulation of Decay Time
• CV modulation of Filter Cutoff
• CV Modulation of OSC pitch
• CV input range +/-5V

Instructions

Mode functionlity: There are two options for mode, one will advance the osc mode with a trigger in the direction it was last selected manually (up or down) or you can select the mode with a CV, 0-5V. You can toggle between these functions by long pressing both buttons 

Power header orientation: This the PSIpower scheme so there is no polarity on the power header, either way is fine.
