Expert Sleepers - ES-6 Mk2 (CV to lightpipe interface)


Expert Sleepers ES-6 converts control voltages into digital, optical signals in lightpipe format. The inputs of the mk2 version are equipped with multicolor background lightning.

Attention: An ES-3 is necessary for using the ES-6!



The ES-6 can convert up to eight control voltages with a range of ±10 V into digital signals that are emitted by an optical output. The analog / digital converter uses a resolution of 24 Bit and 103 dB SNR. It can also be used to expand the amount of inputs of an ES-8.

The module itself offers six input sockets, two more can be provided by attaching an ES-7 expander.

This module bridges the gap between modulars and DAWs. With an ES-6 (or ES-8) you can have fully bidirectional, high resolution CV-communication between Modular Synths and Computers. The possible applications are immense: Controlling VST Plugins with CVs, fully integrating Modular Soft Synths, complex processing loops or combining the power of MAX/MSP and a Modular System.


The ES-6 derives its clock from an ES-3's lightpipe input or ES-8's internal clock, i.e. an ES-3 or ES-8 is necessary for using the ES-6!
