A/B 12 Stereo Audio Inputs Switch

Audio Switch 12 Inputs


  • • Switch 12 audio inputs
  • • 3 control modes
  • • Midi switching for live performance

A/B Test your audio!

The pongasoft A/B 12 Audio Switch is a 2U FREE utility that lets you switch between 12 audio stereo inputs using various approaches.

3 control modes for the 12 inputs

  • in single mode, only one input is active at a time and you can switch to another with a single click (or key on your keyboard). Perfect for A/B testing!
  • in multiple mode, any combination of inputs can be active at a time (similar to the Solo concept).
  • in instrument mode, you control the switch as if you were playing an instrument. Perfect for quickly coming up with creative ideas or live performance.

External control

  • 12 Gate In inputs lets you control the switch from another device
  • 12 Gate Out outputs lets you control other devices from the switch (ex: a Kong device).

A/B bank switching

The switch is split into 2 banks of inputs which can be independently turned on or off. A convenient control also lets you instantly toggle between the 2 banks, effectively implementing another level of switching.

Miscelaneous features

  • Each switch can be labeled independently.
  • Each switch has its own volume control.
  • A soften toggle helps in eliminating clicks and pops that can occur during switching.

Although designed as a utility, the switch can be used very creatively as well!

Product details


Check the documentation for instructions about how to use the switch.

Example of usage

  • Have multiple versions of an audio you want to compare (ex: different mastering)? Simply connect them to A1, A2, etc... and use Single mode to instantly switch between the different versions.

  • Want to gate your sound(s)? Connect only one bank, leave the other one empty and use the CV Bank input connected to a Matrix to switch between A & B (sound / no sound => gate effect).

  • Looking for inspiration? Connect any number of loops (DrRex, Audio tracks, etc...) to the switch and use Instrument mode to "play" portions of a loop with your hardware keyboard. This would be equivalent to muting portions of a waveform, except it is way easier to do and dynamic: no need to edit the sequencer track.

  • Easily toggle between various samples in a live environment using the Single mode keyboard switching capability.
