Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Behringer 911 Envelope Generator Eurorack Synthesizer Module.

Setup and maintenance

  • Requires an S-Trigger input; a CV/Gate to S-Trigger conversion is needed for proper functionality with Moog System standards.

    Source
  • Users suggest adjusting the VCA's "bias" setting to control how open it is by default, which can help manage continuous sound issues.

    Source
  • Users recommend connecting the keyboard's trigger signal to the envelope generator and then routing its output to the VCA's control input to manage sound release.

    Source

Mods and upgrades

  • An inexpensive soldering mod can convert CV/Gate to S-Trigger, ensuring compatibility with the Behringer 911 module.

    Source
  • A simple soldering mod with a single transistor and resistor can convert gate signals to S-trig for better compatibility with the Behringer 911.

    Source

Features and functionality

  • The Behringer 911 replicates the S-Trigger format used in Moog System 55/35/15, not the more common Eurorack standard.

    Source
  • Some envelope generators may continuously cycle without a trigger to reset them after the release stage, causing persistent sound issues.

    Source
  • It's essential to convert CV signals on the interface module as V-trigs and S-trigs operate oppositely, impacting the triggering process.

    Source

Software and compatibility

  • The Arturia Keystep Pro can output S-trig signals, solving compatibility issues with the Behringer 911 module when configured via the MIDI Control Center.

    Source
  • The Arturia Keystep Pro is noted as an effective solution for triggering issues with the Behringer System 55, taking only 10 minutes to set up.

    Source

User experience

  • Users report that connecting the inverted output of the envelope to the VCA can lead to constant sound issues, recommending using the non-inverted output for silence after release.
