Hook FM's play screen: Brooklyn at night, the chord name, the drone and the four knobs

01What's in it

drone	moog-style ladder or arp 2600-style. calm for 5 minutes, then the warble eases in
chords	cs-80 style, two layers a note, filter swell, slow vibrato. always in the city's key
wander	picks the next chord every few bars, so it plays itself
arp	six speeds, four patterns, octaves and gate, on the tempo

fx	two chains, drone and chords: a dj filter (low-pass left, high-pass right) into a tape delay with throws
cities	21, from brooklyn to buenos aires, each with its own scale, sound and skyline
patterns	64 slots that bring back the whole sound
screens	every button opens its own

the effects screen — fx: filters and delays

the world map screen — glo: the world map

in the browser

open try it and press switch on. give it a few seconds to wake up.
the keys A S D F G H J play the chords. drag a knob with the mouse.
9 is arp, Z X move the chords' octave. the rest is in the guide.

on your fm-1

press install. the browser asks once to use midi: allow it.
don't unplug it while it writes. when it restarts, it's hook fm.
