Valentines Day
A romantic song. valentine.orc valentine.sco
New Age
A flute riff based on a pretty good waveguide flute, some ocean wave sounds and a plucked instrument. newage.orc newage.sco
TeknoBubble
Sort of a techno song. This makes use of some unusual resonant filter techniques. Metal bass passes the resonance portion of the signal through a waveshapping table to add some heavy distortion. Another one uses two resonances tuned 1/5th apart, another tracks the rms of the resonance and uses it to control an FM oscillator, another tracks the rms of the resonance and uses it to control filtered noise. tekbbl.orc tekbbl.sco

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.
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.
