Squark Box
16-neuron feedback synthesizer
Free
Sixteen neurons in feedback, listening and answering each other. Steer it, nudge it, strike it, and hear it find its own rhythms. Now on iPhone, with MIDI Learn.
Squark Box is a sixteen-neuron feedback network you can play, built in the spirit of the analog neural-network synthesizers of the late 1980s and early 1990s.
It is a small cybernetic system where every neuron listens to the others and answers back. Think pulses, drones, chirps and slowly shifting rhythms, held somewhere between equilibrium and chaos. You don't tell it what to play; you steer it, and it steers itself.
• 16 neurons on a live round screen. Tap to rewire them, or turn the seeds for a new network.
• Feedback everywhere: neurons pulse, resonate and pull each other into step or out of it.
• A rungler: a shift-register pattern generator, for patterns that repeat or wander.
• Twin resonant filter peaks that sing.
• Modulation: any neuron can move any knob, so the network can turn its own controls.
• Rest, to break chatter into clusters, and STRIKE, to jolt the whole network.
• A spring tank and a blur, for space.
• Four memory slots.
• Mutate nudges a few knobs; Dice randomizes the whole box, cables and all.
• MIDI Learn in the app: give any knob or button to a control on your MIDI controller.
• For iPhone, iPad and Mac: AUv3 for AUM, GarageBand, Logic and Live, as well as a standalone app.
Free, with no ads, no account and no data collected.
• Now on iPhone
• MIDI Learn in the app: right-click a knob or button on the Mac, or hold it on iPad and iPhone, choose MIDI Learn and move a control on your MIDI controller.
• The rungler gets a patch cable: send its clock from any neuron
• Noise now reaches full hiss, Feedback and Q do much more across their travel, and the box starts lower, with more weight.
• STRIKE moves next to GAIN.
• Any cable can be moved from either end.
• Dice goes easier on the effects.
• Tap the spring tank to strike the springs.
• Map Strike, Mutate, Dice and the tank to a pad or button from your host.
• MOD DEPTH now switches off after one knob; hold it to keep it on.
• On the Mac, the Audio Unit now loads in GarageBand.
• On iPad and iPhone, the app keeps your patch and memories when it closes.
