The implementation of modal processors, which involve the parallel combination resonant filters, may be costly for applications such as artificial reverberation that can require thousands of modes. In one embodiment, the input signal is decomposed into a plurality of subbands, the outputs of which are downsampled. In each downsampled band, resonant filters are applied at the downsampled sampling rate, and their output is upsampled and filtered to form the band output. In these and other embodiments, a feature of responses of the mode filters have been optimized to minimize an aspect of a residual error after a point in time.

A reverberator based on a room response modal analysis is adapted to produce distortion, pitch and time manipulation effects, as well as gated and iterated reverberation. An example modal reverberator is a parallel collection of resonant filters, with resonance frequencies and dampings tuned to the modal frequencies and decay times of the space or object being simulated. In one example, the resonant filters are implemented as cascades of heterodyning, smoothing, and modulation steps, forming a type of analysis/synthesis architecture. By applying memoryless nonlinearities to the modulating sinusoids, distortion effects are produced, including distortion without intermodulation products. By using different frequencies for the heterodyning and associated modulation operations, pitch manipulation effects are generated, including pitch shifting and spectral inversion. By resampling the smoothing filter output, the signal time axis is stretched without introducing pitch changes.

A sample library for sample notes, wherein each note has been samples at a plurality of dynamic layers, each note having a main sample and a plurality of impulse response samples. Each impulse response sample corresponding to a deconvolution of the main note and one corresponding dynamic layer sample. During playback of a note the main sample is convoluted with a corresponding impulse response sample to produce a simulated target note.

A musical instrument adapted for use with a turntable. Said apparatus uses a rotary pulse generator to create musical tones when in contact with the rotating platter of the turntable. Said apparatus mounts to the turntable in such a way that a rotary pulse generator rotates when in contact with the rotating turntable platter. As the radius at which the rotary pulse generator contacts the turntable platter is increased the frequency of the tone produced increases proportionally, likewise when the radius at which the rotary pulse generator contacts the turntable platter is decreased the frequency of the tone produced decreases proportionally allowing a range of pitches to be sounded.
