• Functional: 100% tested and working flawlessly. All sealed Alps potentiometers, switches, and gold-plated jacks feel tight and responsive.
  

Key Features & Specs:

• Ultra-Tight Timing: Powered by a fast 32-bit RISC processor to generate a 100% jitter-free master clock from its internal generator (30–180 BPM) or derived from an audio pulse/analog 16th-note trigger from your DAW (30–280 BPM).
  Channels 3 & 4: Dedicated Analog Clock & Reset outputs (0/5V) for modular setups, vintage sequencers, and arpeggiators.
• 4 Independent Clock Streams: Each channel features its own dedicated MIDI output.
  
  Channels 1 & 2: Switchable between MIDI Out and 24-ppq DIN Sync (Roland Sync).
  
  Channels 3 & 4: Dedicated Analog Clock & Reset outputs (0/5V) for modular setups, vintage sequencers, and arpeggiators.
• Hands-On Groove & Timing Control: Dedicated, menu-free hardware controls per channel for 16th-note shifting, fine timing offset (great for compensating latency or pushing/pulling the groove), individual swing/shuffle patterns, half/normal/double tempo switches, and synched mute/unmute buttons.
• Memory & Software Editor: Store and recall complete setups directly on the unit, control parameters via MIDI, or create custom swing patterns and time signatures (e.g., 5/4, 7/8) using the free SND software editor.
• Built Like a Tank: Heavy-duty steel chassis (217 x 160 x 68 mm) with calibrated center-click pots.
