Keith McMillen Instruments

Keith McMillen Instruments builds compact expressive controllers for musicians and producers. The SynthForSale listing is the K-Board Pro 4, a USB MIDI keyboard designed to provide detailed performance control in a portable form. It should be assessed by key response, pressure or touch sensing, mapping, USB connection, software support and power rather than by oscillator or filter specifications, because it is a controller rather than a sound source. The brand suits players who need expressive input for software synthesisers, samplers and modular interfaces.
