Analog Synthesis
rezfiltr.orc rezfiltr.sco
This set of instruments is based on a 2-pole resonant low-pass filter I wrote.
- Table based filter instrument
- PWM instrument
- Distortion filter
- Filtered Noise
- Buzz instrument
- FM Based Rezzy Synth
- 4 Pole Rezzy
- 6 Pole Filter
- Mandelbrot's Snowflake Waveform with 4 Pole Filter
- Flowsnake Waveform with 4 Pole Filter
- Saw Ramp Transform
- Oscillator Sync
Waveguide Physical Modeling
physmodl.orc physmodl.sco
These insturments are based on waveguide physical models.
- Karplus-Strong Algorithm: A csound version of the classic plucked string algorithm.
- A Waveguide Bass: A waveguide bass implementation.
- Stinson's Weird String
- J. O. Smith's Reed Instrument: A waveguide clarinet-like instrument derived from Smith's instrument.
- Perry Cook's Slide Flute: A waveguide flute based on Perry Cook's instrument.
- Perry Cook's Clarinet: A waveguide clarinet based on Perry Cook's instrument.
- Wave Drum1: Bell like tones
Tone Wheel Organ with Rotating speaker effect
Basic Organ without deflectors in the leslie.
rotorlsl.orc rotrolsl.sco
Advanced Organ with deflectors, key click and percussion for use with a MIDI file.
rotormid.orc rotormid.sco rotormid.mid
These are my attempts at simulating the classic Hammond B3 organ sound. The advanced organ is
actually getting pretty close to the real thing.
TB303 with Sequencer
tb303.orc tb303.sco
This is my first attempt at simulating the TB303.
More advanced TB303
tb305.orc tb305.sco
I added some controls similar to a real TB. Still does not have slide and accent and the first note of the sequence working properly. This filter does not sound as harsh as my other one and should be useful in a variety of applications.
Fractal Chaos
fractals.orc fractals.sco
These instruments are based on fractals, chaos or related systems.
- The Lorenz Attractor
- Duffings System or Cubic Oscillator
- Planet Orbiting in a Binary Star System
- The Rossler Attractor
- K A Oscillator
- Feather Fractal
- Simple Chaos 1-5
Parametric Equation Instruments
Orchestra Score
These instruments are based on the epicycloid and the hypocycloid. These are the shapes generated by the popular game Spirograph. Also included is a Banchoff Klein bottle.
- Epicycloid Spirograph
- Hypocycloid Spirograph
- Banchoff Klein Bottle with rotation
Some simple FOF & Granular Instruments
These instruments are based on granular synthesis.
3D Sound
dopplr.orc dopplr.sco
These instruments are based on doppler effects. To run this score you may wish to download the following sample.hahaha.wav
- Filtered Noise Left to Right
- Filtered Noise Right to Left
- Sample Left to Right
- Sample Right to Left
- Buzz with Lorenz orbital doppler effects.
- Velocity doppler
