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

LEADStarfield Lead

A soft triangle with a quiet saw an octave above it, swelling in slowly, echoing deep and wobbly from side to side into a vast, dark hall: a floating, starry lead. Play slow, sparse notes and leave room for the echoes. Macros: Echo, Space, Bright, Attack. Macro 8, Master, is the output level.

LEADDub Echo Lead

A short, resonant square stab into dark, gritty 12-bit echoes that repeat on and on and fade: a dub lead. Play short off-beat stabs and let the echoes answer; Feedback keeps them going longer. Macros: Feedback, Echo Tone, Cutoff, Space. Macro 8, Master, is the output level.

LEADOrbit Lead

A saw-and-square lead that circles slowly around you: Undertow pans it from side to side, echoes bounce the other way, and a hall holds it all. Play long, held notes, on headphones best, and follow it round. Macros: Orbit Rate, Echo, Space, Bright. Macro 8, Master, is the output level.

LEADSci-Fi Siren

A triangle and a square an octave up that slide into every note and rise and fall slowly in pitch, the LFO starting over on each new note, echoing into a big space: an old science-fiction siren of a lead. Play slow melodies and hold the notes to hear them wail. Macros: Siren Rate, Glide, Echo, Space. Macro 8, Master, is the output level.

LEADStereo Split Lead

Two saws, each pulled apart into the left and right by Osc Spread and the cutoff spread across the sides, widened again by Bedrock with its bass kept centred, in a bright plate: a huge, wide lead. Play big melodies; Width pulls the sides further apart. Macros: Width, Bright, Glide, Space. Macro 8, Master, is the output level.

LEADDistant Signal

A thin saw and narrow pulse behind a little pink hiss, swelling in, echoing and lost far back in a long hall: a lead heard from across a valley at night. Play slow, simple phrases and let the hall answer. Macros: Distance, Echo, Bright, Hiss. Macro 8, Master, is the output level.

LEADSurf Spring Lead

A twangy saw and narrow pulse with a quick decay, chopped by Undertow's bias tremolo and dripping through a second Big Red turned well up: a surf lead with its spring tank splashing. Play picked, staccato melodies and quick runs. Macros: Spring, Tremolo, Rate, Bright. Macro 8, Master, is the output level.
