morpho-snn duet — play with a developing brain

Organism

Dialogue

relatedness = shared pitch material between your call and its answer (0–1)

Mean firing rate

gray band = homeostatic target · ▎births · ▎prunes

Development log

Legend

excitatory neuron (circle)

inhibitory neuron (square)

sensory neuron — your notes arrive here

ringed = musical voice (output)

green ring = newborn structure

red ✕ = pruned

violet ring = walker (melodic agent)

gold diamond = modulator — rarely nudges the key round the circle of fifths

Duet mode: you are the environment this brain develops in. Turn on sound, press run, then play — pads, the letter keys shown on them, or a MIDI keyboard (enable midi). Your notes become spike bursts in the gray sensory neurons, wired to the anatomy that sounds the same scale degrees. There is no metronome here: what it plays back is shaped by what you play, stdp strengthens the pathways you use, and development grows around them. Hit ✚ reinforce when you like a response — it feeds the structures that made it. Amber flash = you, violet flash = the model.
