Pocket Pedal is an indispensable controller for the performing musician. With the addition of any volume pedal and footswitch, keyboard 8 guitar-synth players can send MIDI volume, modulation, and sustain controls on all 16 MIDI channels at the same time. For owners of muiti-effects processors, Pocket Pedal" provides a convenient and cost effective way of providing dynamic control over effects parameters. Pocket Pedal" is a handy controller for automated mixdowns - converting any resistive input into MIDI Controller messages for VCAs. Connect a photocell to Pocket Pedal" and control MIDI parameters with a light source. What's more, MIDI retro-fitters can install Pocket Pedal into a guitar, home piano or organ to send pitch-bend modulation or MIDI Volume messages.
