  • Want to use your USB MIDI keyboard without turning on your computer? The PianoBox Mini is the solution.
  • You can connect any USB MIDI keyboard directly to the PianoBox Mini - without the need for your computer! This unique feature allows you to connect the PianoBox Mini to any keyboard - even if it doesn't have MIDI out! Of course, the PianoBox Mini also includes a MIDI input for keyboards or other MIDI devices that have a standard MIDI out port.
  • The PianoBox Mini is designed for portability and includes a built in rechargeable battery, so you don't have to worry about lugging along a power supply.

Simply use a USB MIDI interface such as the MidiLink Mini to connect the PianoBox Mini to your computer, and use it for playback instead of your computer's soundcard. This will get rid of any delay or latency problems you are having with software such as Sibelius, Finale, PrintMusic, MusicTime, Sonar, Pro Tools, etc.

  • This is a "finish-it-yourself" kit. The surface mount parts are all pre-soldered, and the latest firmware is already installed. The panel and all other parts (including the Rogan knobs) for the circuit are included. You can swap our panel for another manufacturer's panel too! Assembly instructions are available on the Sound Study Modular website.
  • TEXTURE SYNTHESIZER: Clouds is a granular audio processor that creates textures and soundscapes by combining multiple overlapping, delayed, transposed and enveloped segments of sound taken from an audio recording buffer.
  • COMPREHENSIVE CONTROLS: Classic controls such as grain position, size, and pitch are provided. Clouds can superimpose up to 16 grains simultaneously and thus create thick textures. Control over texture density, independently of grain size, is thus provided. An external trigger input allows grains to be seeded in sync with LFOs or rhythmic generators.
  • To provide a richer variety of timbres, Clouds allows the shape of the grains envelope to be morphed from sharp rectangular edges to a smooth bell curve. In addition, a diffusion network can further dissolves the edges of grains into blurry textures.
  • Grain mesh modes automatically adjust grain density, size, and the offset between successive grains in order to generate a continuous stream of audio that can be pitch-shifted / time-stretched in the manner of old-school samplers (or time-domain pitch/time processors).
  • Clouds delay memory ranges from 1s to 8s depending on audio quality settings.
