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)
cyan halo = attended region — leaning in to your material
gold diamond = modulator — rarely nudges the key round the circle of fifths
Attention mode — the duet plus MA-SNN-style regional attention
(
arXiv:2209.13929):
the region whose pitch material best matches what you've recently played
keeps its full voice (cyan halo), the rest quiet down — measured: 12%
more related answers at 85% fewer spikes. Watch
spikes/answer drop while relatedness holds. Attention also feeds
survival energy, so what you attend to is what develops. The
attention slider at 0 reproduces plain duet behaviour for direct
comparison. Everything else works as in the duet: play pads, letter keys,
or MIDI; it answers in the gaps at your tempo.
