MetaModule Audio Expander Features

The MetaModule Audio Expander is an expansion module that packs professional-grade audio I/O into a compact 6HP size.

Additional I/O

Adds the following audio I/O to the MetaModule:

  • 6 CV/Audio inputs - 24bit/48kHz, DC-coupled, +/-10V
  • 8 CV/Audio outputs - 24bit/48kHz, DC-coupled, +/-10V

This allows you to build a large-scale system with a total of 12 inputs and 16 outputs combined with the MetaModule.

High-Quality Audio Processing

Achieves the same high-quality audio as the MetaModule.

  • 24bit/48kHz (expandable to 96kHz)
  • DC-coupled - compatible with both CV and audio
  • +/-10V voltage range - fully compliant with Eurorack standards
  • Low-noise design - clean sound generation

Ribbon Cable Connection

Connection to the MetaModule is made via the included 2x5 ribbon cable. A simple design that transfers both power and audio data through a single cable.

Calibration Function

Jack calibration information is stored in non-volatile memory. Settings are preserved even after power-off, ensuring consistently accurate CV/audio processing.

Usage Examples

The MetaModule Audio Expander can be used for the following applications:

Complex Patching

  • Polyphonic synthesis using multiple VCOs simultaneously
  • Building parallel effect chains
  • Multi-track recording/mixing
  • Large-scale integration with external modules

CV/Gate Expansion

  • CV outputs from multiple sequencers
  • Modulation source expansion
  • Additional envelope generators
  • Adding LFOs and CV processors

Mixing and Routing

  • Simultaneous mixing of multiple sound sources
  • Send/return effect loops
  • Parallel processing
  • Cross-feedback patching
