Resound is an audio delay effect processor.

It emulates vintage magnetic-tape echo units.

A controllable noise level allows the right amount of grit, distortion, and flutter through. The Reverse mode adds further flexibility: by playing each delay backwards, Resound can produce unique effects that magnetic-tape units could never make.

Features:

• Delay time up to 30 seconds when synced to host tempo, up to 2 seconds when not synced.
• Controllable noise level and high-pass filter.
• Reverse mode to produce more complex and interesting delay textures.
• Capable of self-oscillation, even without any input source.
• MIDI Learn mode for easy integration with any MIDI hardware controller.

Changes in v1.6.0

• Native 64-bit VST plug-in for Mac OS X (64-bit VST support requires Mac OS X 10.6 or greater; 64-bit Audio Unit requires Mac OS X 10.5 or greater; all other formats require Mac OS X 10.4 or greater. )
• Integrated undo and redo, with unlimited history size.
• Split mechanical tape emulation controls into separate Noise and Flutter parameters.
• Category support in preset browser.
• MIDI Program Changes are now multi-threaded, and so will no longer potentially stall the audio synthesis.
• Fix for GUI freeze that could occur in certain Mac OS X VST hosts.
• Slightly reduced CPU usage and removed potential audio thread stall that could rarely occur when editing parameters.
• Fix for issue that could cause some presets to be instantly marked as changed after opening them in Pro Tools or Maschine.
• Factory presets now load significantly faster.
• Preset meta data (ie, author name, notes, tags) is now correctly displayed after loading an .FXP based preset or restoring a saved project.
• VU meters now automatically reset their overload status after a few seconds.
• Various host compatibility fixes.
• Now with a printable PDF manual.

Changes in v1.5.0

• Noise parameter is now scaled such that wow, flutter, and mechanical noise of the tape machine are completely absent at 0%. Older presets will still sound identical.
• Reversed delay tempo syncing has been improved with hosts that don't provide accurate PPQ.
• Integrated Preset Browser, with meta-data, tags, searching, and hot-swap support.
• Reduced CPU usage.
• Various host compatibility fixes.
• Additional presets.

New in v1.4.1

• Native 64-bit versions for Windows (VST) and Mac OS X (Audio Unit).
• Compatibility fixes for various hosts.
• Mac OS X components are now packaged with an uninstaller.
• Vastly reduced memory usage.
• Improved feedback algorithm. For 100% compatibility with legacy projects, the older algorithm can be enabled using the Backwards Compatibility options.
• Fix for an intermittent noisy timbre that could occur under certain hosts.
