Doepfer’s A-119 module is ideal for integrating external signals into the Eurorack modular realm. The module is comprised of three sections that lend everything one would need synchronize their modular rig with external signals: a dual input pre-amp, envelope follower, and comparator.
Allows for a 1/4th inch inputs with gain staging for interfacing with guitars or other synthesizers
An Envelope Follower provides a CV level that mimics the Amplitude level of the incoming signal
A threshold control and gate output allows the user to decided a level which must be crossed to generate a Gate output. Great for synchronizing rhythms to an external audio rhythm.
