Chord Sequencer Modular Synthesizer lleqpue9

4-Lane Independent Bounce Ball Sequencer
Unlike typical 16-step sequencers,
this unit employs a physical model where a ball circulates on a U-shaped track, and a Gate signal is generated the moment it passes the bottom.
This creates a unique rhythm where regularity and randomness coexist.

Balls: 1-16
Speed: 1-99 (high-speed random possible)
Octave: 1-3
ARP: OFF / UP / DOWN

Chord Sequencer Function (Chord Edit Mode)
Plays 4 chords sequentially, automatically assigning chord tones to each lane.
Arpeggio-like distributed chords are naturally generated.

Root: C to B
Mod: Maj / min / Maj7 / min7 / dim / sus4 / add9, etc.
Steps: Chord duration
Currently playing chord indicated by @
External chord progression changes possible with TRIG-IN

AutoTune (Independent for each lane)
Automatically corrects the pitch of 1V/Oct compatible VCOs.
Allows for immediate tuning even if pitch drifts during performance.
AutoTune equipped for each lane (Lane 1-4)
Connect VCO output to TUNE IN terminal for use.

BPM & External Clock Support
Internal BPM: Changeable via ENC operation (default 120)
CLK-IN: Fully synchronized with external clock (4ppqn)
CLK-OUT: Outputs clock to external devices
Ball speed and chord progression synchronize with BPM changes.
