BOSS MD-500 Modulation Workstation

The ultimate high-powered modulation hub, combining pristine 32-bit AD/DA conversion, 32-bit floating-point processing, and a 96 kHz sampling rate for studio-grade audio quality. Featuring 12 distinct modes and 28 modulation algorithms—including vintage recreations like the Roland Dimension D, CE-1 Chorus Ensemble, and Script Phaser, alongside modern pitch/filter algorithms—the MD-500 offers virtually limitlessness modulation capabilities in a compact enclosure.

Key Features & Technical Specs:

  • A/B Simul Mode: Run two independent modulation patches simultaneously in series or parallel, or route them to separate outputs.
  • Flexible Insert Loop: Insert drive pedals or external gear directly into the loop to position modulation effects before, after, or around your dirt section.
  • Deep Memory & Display: Graphic LCD screen for straightforward menu navigation, with 297 onboard patch memories.
  • I/O & Control: Full MIDI I/O, USB-MIDI for connection to the free MD-500 Editor/Librarian software, stereo inputs/outputs, and external footswitch/expression pedal jacks.
  • Power: Requires standard 9V DC center-negative power supply (not included) or 4 AA batteries.
