Understanding TRS-MIDI Type A vs. Type B: Compatibility and Usage

by

In the evolving landscape of music technology, the traditional 5-pin DIN connectors for MIDI (Musical Instrument Digital Interface) are increasingly being replaced by more compact 3.5mm TRS (Tip-Ring-Sleeve) connectors. This shift has led to the emergence of two wiring standards: TRS-MIDI Type A and Type B. Understanding the distinctions between these types is crucial for musicians and producers to maintain compatibility and ensure efficient MIDI communication within their setups.

TRS-MIDI Type A and Type B: Wiring Configurations

The primary difference between Type A and Type B lies in the assignment of MIDI signals to the TRS connector’s contacts:

  • Type A (MIDI Standard):
    • Tip: MIDI Transmit (TX)
    • Ring: Voltage (V+)
    • Sleeve: Ground (GND)
  • Type B:
    • Tip: Voltage (V+)
    • Ring: MIDI Transmit (TX)
    • Sleeve: Ground (GND)

These differing configurations mean that connecting a Type A output to a Type B input (or vice versa) without proper adaptation can result in malfunctioning MIDI communication.

Device Compatibility

Manufacturers have adopted different standards for their devices:

  • Type A Devices:
    • Korg
    • Make Noise
    • IK Multimedia
  • Type B Devices:
    • Arturia
    • Novation
    • 1010music

It’s essential to consult your device’s manual or the manufacturer’s website to determine the TRS-MIDI type it employs. For a comprehensive list of devices and their corresponding TRS-MIDI types, you can refer to minimidi.world.

Ensuring Compatibility

To facilitate proper communication between devices with differing TRS-MIDI types, consider the following approaches:

  1. Use of Adapters:
    • Specialized adapters can convert signals between Type A and Type B. For instance, Retrokits offers adapters designed for this purpose.
  2. Standard MIDI DIN Ports:
    • Utilizing standard 5-pin DIN MIDI ports with appropriate cables can bypass TRS compatibility issues altogether.
  3. Device Settings:
    • Some modern devices feature configurable TRS-MIDI ports that can be set to either Type A or Type B, enhancing flexibility in diverse setups.

Conclusion

Understanding the differences between TRS-MIDI Type A and Type B is vital for ensuring seamless MIDI communication in contemporary music production environments. By identifying your devices’ TRS-MIDI types and employing suitable adapters or settings, you can maintain compatibility and optimize your MIDI setup.

FAQ

  1. What is the main difference between TRS-MIDI Type A and Type B?
    • The primary difference lies in the wiring configuration of the TRS connector’s contacts, affecting signal transmission between devices.
  2. Can I connect a Type A device directly to a Type B device?
    • Direct connection may lead to communication issues; using an appropriate adapter is recommended to ensure compatibility.
  3. How can I determine the TRS-MIDI type of my device?
    • Consult the device’s manual or the manufacturer’s website for specifications regarding its TRS-MIDI configuration.
  4. Are there adapters available to convert between Type A and Type B?
    • Yes, companies like Retrokits offer adapters designed to bridge the gap between different TRS-MIDI types.
  5. Is TRS-MIDI replacing traditional 5-pin DIN connectors?
    • While TRS-MIDI offers a more compact solution, 5-pin DIN connectors remain prevalent; both are used based on device design and user requirements.
