| | | |
If you have run ABox2, you can tell your browser to "Open the file in-place".
Or you can save the circuit your hard-drive.
The bandwidth measurements are for a Pentium2 CPU.
|
|
There are still more circuits in the Library
|

| | | |
Jambots
|
|
Jambots are circuits that play music, jamming robots if you like.
Most of them are based on repeating sequences of random notes.
Changing the seed values results in a different piece of music.
One might imagine each circuit as a sort of a radio receiver...
The dozens and dozens of circuits that follow were all developed by Andy over the past few years.
Naturally, they reflect his own taste in music.
...You might like to listen and enjoy or perhaps try and tune in to another station.

| |
NEW!
Two mutating drums sequence through an echoed rythm pattern acompanied by a pulse bass.
In the background, a stack of tuned resonators swell and ebb into the darker depths.
| | |
| |
NEW!
Two overly warped pianos playing simple phrases create an often pleasing sing song melody.
Although they do seem to get stuck from time to time.
An 1/8 note pump and simple kick snare combo keep the beat.
| | |
| |
NEW!
Resonators driven by band limited noise produce swirling string like drones and plucked leads.
Triangle wave bongos mostly follow a fixed sequence to create a digital meditation.
| | |
| |
|
An uptempo piece driven by a metaloid 16th note bass pump.
A sense of lyric and response is created by fractionalized modulation indexes.
Hi-Q noise filters add a digital panache.
| | |
| |
|
All triangle wave sounds.
Bongo lines are played by two pairs of triangle waves.
Three more sets of triangle waves play swirling themes in a pentatonic scale.
A low frequency triangle keeps the beat.
| | |
| |
|
A swaggering beat and wah-wah synth create a dreamy background for simple descending vibraphone lines.
Occasionaly a slide guitar plays, unsure of wheather it is forwards or backwards.
| | |
| |
|
A best-fit filter creates random sequences that drive a lead synth, abrupt accompanyment and bass.
Several waited bit switches, adjusted by sliders, control the arrangement.
The result is a somewhat groovey comp dialog between the lead and the choir.
| | |
| |
|
A somewhat arid piece wherein a rich sound source drives a bank of tuned resonators.
Slowly sweeping some of the frequencies brings out various harmonics.
| | |
| |
|
Noise, filtered by an FFT/ADSR/IFFT, is funkified by a resonator with variable time delay.
Desynchronizing the circuit every few bars produces even more interesting sounds.
| | |
| |
|
1/f sequences provide notes for a wah-wah synth, organ and bass.
4 bar logic gates switch the arrangement between wandering leads and 7 note phrases with warpy chords.
Panned wind and sloppy drums complete the piece.
| | |
| |
|
ADSR's emit patterns for a random note generator to dance around.
The 3/4 time signature with a simple kick drum create the jig-like atmosphere.

| |
|
A pair of 23-tone triangle waves swing around blocks of cubicals attempting to
keep up with an FM synth babbling nihilisms from on high.

Sarcastic 23 tone bass lines summerize a poor attitude in a hectic office.
| | |
| |
|
Flanged delta guitar accompanied by a classic echoed
random modulated synth and tock block.
| | |
| |
|
A slow day at the lab gave rise to these modal piano stylings.
Adding some key changes may liven it up a bit ...
| | |
| |
|
The logistic equation provides the notes for this relaxed piano synth.
Chord changes peppered with key modulations add an interesting voyage aspect.

| |
|
Three note harpsichord played by an ADSR has a baroque flavor.
| | |
| |
|
A string synth plays stacatto for a few bars
then an FM lead synth takes a straight line to center stage.
An up-down octave bass acompanied by paint jugs completes the piece.
| | |
| |
|
Two note warpy FM synths accompanied by bass, kick and snare play a repeating gospel chord progression.
Changing the pattern and note seeds transforms the piece into something completely different.
| | |
| |
|
A modulated Spirograph formula is used as lead instrument.
Strong Bass, simple hi-hat, and mystic one note vibraphone complete the piece.
| | |

A stacatto guitar and chaotic beat_bass set the background for this
5/4 portamento expedition of two triangle waves.

Components are cascaded to build lines for a guitar and electric piano.
A bass and drum kit get to improvise at the end of the phrase
resulting in a vamp that you might hear in the fade-out portion of a song.

| |
|
Simple 12 bar blues circuit. Might be used as a basis for a larger circuit.
| | |
| |
|
A shanai like sound is driven by a random walker resulting in a repeating pattern that wanders through modal space.
The swing button adds a hipster componemt.
| | |
| |
|
Lead synth and Bass guitar trade introspective licks backed by matter of fact piano lines and flanged electric guitar.
Or, press the button to get a galloping hook.
| | |
| |
|

with a driving bass line that has something to say every now and then.

Acoustic guitar riff and flutes kick back on the porch with a cold one.
The making of this circuit is described in the artical on Jambots.

As the piece evolves, it gets a bit sparse, then slowly picks back up.

| |
|
Somewhat pointless piece trades riffs between a wobling guitar and a lead syth.
A swaggering bass and 3/4 drum beat keep it all together.

After a mournful wail, a synth is besieged in a desolation of cardboard boxes.
Mandelbrot's equation completes the piece by generateing simple riffs for another synth.

| |
|
It's a distortion unit that inverts the portion of the wave that was
clipped from the signal and sums it back in with the original signal
... kind of like in those old guitar fuzz boxes.
| | |
| |
|
A small tool for varying the harmonic content of various waveforms.
It is a full wave rectifier with variable rectification amount.
Useful for sprucing up boring tones.
| | |
| |
|
An elegant groupable implementation of a pulse width controlable oscillator.
This circuit can also be found in the library under /Oscillators/.

With the addition of tremolo, delay effecs, and new seeds,
Jambot #2 takes on a digital dream like quality.

| |
|
Marcelo has developed two Mini-Moog style synthesizers.
Each features a wide variety of controls including glide, tune, portamento,
mix mod and a host of others.
The first circuit can be run by itself or be controlled by a MIDI input.
The second circuit requires a MIDI input, a keyboard or sequencer for example.

This circuit pits high frequency sweeps against a discordant dirge
of digital ramp waves.
| | |
| |
|
An emulation of d-lusion's Rubberduck softsynth with a chorused bass.
| | |
| |
|
This expansion of the previous circuit harshes out the bass to provide
the stage for some life threatening filter squeals.
| | |
| |
|
With enough complexity, even simple sinewaves become chaotic, as this circuit demonstrates.
| | |
| |
|
This circuit uses the concept of the ratio between wave lengths to build an arpegiator.
Lot's of controls to adjust to create a wide variety of sounds.
| | |
| |
|
An example of building a complex wave from multiple square waves.
| | |
| |
|
A truely magnificant offering.
You'll need several VST plugin's to play this circuit,

"... a little tiny chaos synth that I just use as the top to some beats."
Wherein, two VST Plugins are bombarded by notes.
| | |
| |
NEW!
Multitrack console circuit that feeds 8 wav files into VST Plugins and a mixer.
If you don't have the files specified in the circuit, it's fun to replace them with the
Win98 sounds in the /Media/ directory.
| | |
| |
NEW!
A somewhat dark cruise through a realm characterized by melodius tones and drinking glasses.
| | |
| |
NEW!

Sounds
|
|
An assortment of sounds written by Andy. Some are very strange, some are very big, some are ... well you figure it out.
| | |
| |
| |
|
A mildy acerbic ode to times gone by.
| | |
| |
|
A ring of dampened harmonic oscillators create an etherial wind chime feel.
| | |
| |
|
A very huge ambient sound.
Noise drives three low frequency filters feeding a swept delay.
| | |
| |
|
Logistic equations create both noise and subtle patterns.
Two resonators create panning and wind like effects for this low frequency exploration.
| | |
| |
|
A noise source and many types of filtering create a stormy stage
for an ill tempered screech.
| | |
| |
|
A figure-eight feedback loop with many short random tones.
Perhaps the bug people of Mars playing hacky-sack with those missing probes from Earth.
| | |
| |
|
Ramp waves and ADSR's build a spectrum that is processed by an IFFT.
Careful balancing of driving frequencies results in a descending sweep
reminiscent of an inertialess drive.
| | |
| |
|
A non-linear spring is whacked by random position values.
The cash registers at the droid market ?
| | |

Basic realtime pitch shifting using the FFT/Scale/IFFT objects.
Works well for spoken voice but will butcher most music.
| | |
| |
|
