DD-500 Version 2 Software: New and Improved Control Parameters, Routing Options, and Effects for Increased Performance Flexibility

The feature-packed Version 2 software update brings powerful new performance enhancements and unparalleled flexibility to the DD-500. Even more control has been added, with an improved A/B simultaneous mode for advanced routing as well as new Series and Parallel modes. Five new effect types have been added to the current delay algorithms, plus many updated parameters common to all modes. The update also offers lots of user-requested features, including additional MIDI controls, new modulation types, a feedback loop function for inserting external effects, adjustable input and output levels, selectable EQ position, and more.

Twelve Versatile Delay Modes and Deep Editing Options
With the DD-500's 12 delay modes, you can create any delay sound you can imagine, and then some. Everything you need is here, from warm, gritty vintage delays and tape echo to complex modern delay lines that employ pitch shifting, filtering, and other unique processing. With the hands-on knobs, it's easy to shape essential parameters and create great sounds immediately. Each delay type also includes a semi-parametric four-band EQ, modulation, ducking, and many other parameters, allowing you to dive deep and refine tones with maximum precision.

Unparalleled Sound Quality
In the DD-500, every delay mode has been carefully crafted for a unique sonic personality and highly musical tones at every setting, realized by 32-bit AD/DA and 32-bit/96 kHz processing throughout. And while the delay effects are high-end digital, the DD-500 supports analog pass-through on the straight guitar tone, and you also have your choice of buffered- or true-bypass operation. Along with strengthening the analog dry signal, buffered bypass has the added benefit of enabling carryover, so delay trails are not cut off unnaturally when turning the effect off or switching patches.

Advanced Features for Stage and Studio Use
In the world of sophisticated delay stomps, the DD-500 stands alone in practical usability. The large, integrated LCD fully supports the pedal's immense capabilities, giving you clear visibility of delay time, patch ID, and more on one screen, plus sane navigation for detailed parameter tweaks, naming, and system management. And via USB, it's simple to connect to your computer for remote editing and patch backup with the DD-500 Editor. MIDI I/O opens up many additional control options for advanced setups with effects switching systems and other devices.

Intensive Real-Time Control
With its freely assignable controls, the DD-500 delivers unmatched creative expression and performance flexibility. By default, the A, B, and TAP/CTL switches offer intuitive control for two patches, bypass, bank selection, tap tempo, and more. However, they can be customized to operate in alternate ways, such as providing top-level access to three different delay patches, or allowing you to use two patches at once for layered delay sounds. Instead of tap tempo, you're able to assign the TAP/CTL switch to various real-time functions like Warp or Twist for a wide range of expressive effects. Even more parameters can be manipulated via MIDI commands or by connecting an optional expression pedal or external switches.

DD-500 Delay Modes
•Standard-Clear digital delay.
•Analog-Emulates classic analog "BBD" delays like the BOSS DM series.
•Tape-Emulates the warm sound of tape-based delay units, including the Maestro Echoplex, Binson Echorec 2, and the legendary Roland RE-201 Space Echo.
•Vintage Digital-Emulations of early digital delays from the 1980s, including Roland's famous SDE-2000 and SDE-3000 rack units and the BOSS DD-2, the original stompbox digital delay.
•Dual-Two different delay lines that can be connected in series, parallel, or three different A/B independent modes.
•Pattern-Sixteen different delay lines that can be set independently for all types of unique rhythmic effects, with Gate mode for slicer-like pattern effects.
•Reverse-Backwards delay for cool psychedelic effects and other unique tones.
•SFX-"Special effects" delays with highly unique sound characters.
•Shimmer-Pitch-shifted delays with stereo pitch-shifter and overtone modes for lush, heavenly textures.
•Filter-Delay with selectable sweeping or touch-responsive dynamic filter types.
•Slow Attack-Ethereal delays that fade in with playing dynamics.
•Tera Echo-Spacious, animated ambience effect derived from the innovative BOSS TE-2 pedal.
