An exact hardware replica of the Mutable Instruments Ears, which is based on the Music Thing Modular's Mikrophonie.

The ridges on the panel are less defined than on the Mutable version, so the texture is a bit more subtle.

4 HP | 25mm deep | 20mA

About the Mikrophonie:

  1. Mikrophonie is a microphone preamp with a piezo contact mic built into the panel. It is an easy way to bring environmental noise and feedback into a modular system, inspired by the early days of electroacoustic music in Paris and Cologne, and by the contact microphone and phonograph cartridge experiments of John Cage, Gordon Mumma, Robert Ashley and Nicholas Collins.
  2. The panel is PCB with patches of raw fibreglass and raised gold-plated traces. Rubbing it with a finger or a plectrum creates quite a wide range of sounds. The back of the panel is plated and grounded for shielding.
  3. The mic will also pick up all the physical sounds in your modular - patching, cables rustling, switches, fingers on knobs - without picking up airborne sounds like the sounds your modular is making. At very high sound levels will pick up vibrations from the speaker output and start to feedback.
  4. Patch Ideas:
    • Gently tap the piezo element to produce a strong trigger, that will open a low pass gate or trigger a Maths envelope.
    • Use the outputs as voltage sources, rather than audio sources; FM an oscillator with the output. Works well with low frequency signals like pinged springs.
    • Use channels 1 or 4 in a Maths as an envelope follower, with configurable rise and fall.
    • The circuit is DC coupled so that very low frequency modulations (i.e a bouncing spring, a flexing piece of wood) might be like an LFO source. However Peizo elements only produce a signal while their stress is changing. Pressing and holding the panel will not produce a sustained high signal.
    • You can also use the mic input as a massively highgain bright op-amp distortion/fuzz/boost for other modular signals.
    • Switches + patching + touching patch cables = fun.
