Low frequency oscillator providing phase-staggered multi-channel midi-output control-signals
First Claim
1. A system for generating an adjustable phase-staggered plurality of periodically-varying control signals, said system comprising:
- a low-frequency oscillator for generating a periodic reference signal;
a first adjustable phase-shifting element for applying a first adjustable phase-shift to said periodic reference signal to produce a first phase-shifted signal;
a second adjustable phase-shifting element for applying a second adjustable phase-shift to said periodic reference signal to produce a second phase-shifted signal; and
at least one output element for collectively producing a first outgoing control signal responsive to said first phase-shifted signal and a second outgoing control signal responsive to said second phase-shifted signal, wherein said first outgoing control signal and said second outgoing control signal are signals of MIDI format.

Abstract
Synthesis of time-varying MIDI control signals useful in creating spatial perturbation, chase effects, new forms of rich musical timbre modulation, spatially-distributed timbre constructions, and other types of sonic animation. Phase staggered multi-channel MIDI-format control signals are created using one or more low frequency oscillators, each with a plurality of phase shifting elements. Control signal waveshapers may be included in the control signal synthesis chain. In an exemplary embodiment, frequency and phase parameters are adjustable, with values that may be recalled from stored program control and/or modulated in real-time by incoming MIDI control signals. In another exemplary embodiment, each outgoing control signal additionally may be independently assigned a selectable waveshape, which is determined by values that may be recalled from stored program control and/or modulated in real-time by incoming MIDI control signals.
