Hardware

The panel as a piece of gear: bat levers, round arcade buttons, gripped knobs on a printed plate.

KEYS/PLUCKPendulum Pluck

A glassy pluck swinging up a pentatonic run and back down again, the sequence running forward then backward, into a ping-pong echo and a plate. Hold C4 for it as written; any key moves the whole swing. Macros: Cutoff, Pluck, Echo, Space. Macro 8, Master, is the output level.

KEYS/PLUCKSkank Organ

The reggae organ skank on every offbeat: a square and a triangle a fifth above it, short and percussive, in a small room, doubling up at the end of the bar. Hold C4 for the chord's root and move it with the changes. Macros: Length, Bright, Room, Fifth. Macro 8, Master, is the output level.

KEYS/PLUCKWind-Up Melody

A little music-box tune that plays itself, high triangle tines with a faint metallic shimmer, warbling slightly like an old mechanism, in a plate. Hold C5 for it as written, or lower for a darker box. Macros: Shimmer, Ring, Warble, Space. Macro 8, Master, is the output level.

KEYS/PLUCKSwing Clav Groove

A quacking clav playing a swung sixteenth-note funk part, the accented steps digging in harder, the lows trimmed so it sits above the bass. Hold C4 for it as written; ride Swing to loosen or tighten the groove. Macros: Quack, Swing, Cutoff, Gate. Macro 8, Master, is the output level.

KEYS/PLUCKTwelfth Organ

An organ built on a stop a twelfth above: a square at the played pitch and a soft triangle an octave and a fifth over it, the knob's end at Range 19. The two lock into one hollow, reedy tone, like a mutation stop pulled out. Steady and unhurried, fast to speak. Macros: Twelfth, Bright, Space. Macro 8, Master, is the output level.

KEYS/PLUCKMinor Third Pluck

A short plucked saw with a second voice a minor third above, three semitones: one finger plays a minor chord shape, the sad little interval inside the old seven-semitone Detune. Left at Range 7, where a turn of the knob still reaches a fifth. Quick and dry, for staccato lines. Macros: Third, Cutoff, Decay. Macro 8, Master, is the output level.

KEYS/PLUCKPaisley Stab

A psychedelic stab: two saws a fifth apart snapped shut by the filter, through Jacuzza on Split, its bubbles and jets side by side and wandering, then ping-pong echoes and a spring, so every hit swirls off into the room. Play short hits and move them around the keyboard; the fifth moves with you. Macros: Swirl, Jets, Echo, Spring, Bright. Macro 8, Master, is the output level.
