What DelGrain does

Granular and tape delay lines run in parallel in DelGrain, and the left and right channels each have their own time settings. The granular size control covers 1 ms to 1024 ms, with a tempo-sync mode and a triple option. The developer notes that grain size and grain length can be set in tempo-based values, with a SEMI tune feature covering 12 semi-units. Grain placement can be set to pre-delay, inside the delay, after the delay, or in parallel.

Key features

• Granular and tape delay. Two delay engines run side by side. The granular engine plays audio back as grains, and the tape engine provides a conventional delay with low-pass and high-pass filters on the tape path.
• Grain placement. Grain placement sets where the granular processing sits in the chain: pre-delay, inside the delay, after the delay, or in parallel with it.
• Distortion module. A distortion module processes the audio before it enters the granular delay, with a Rectify mode among its options.
• Filter section. The analog-modeled filter section includes a 12 dB low-pass and high-pass combination, a band-pass filter with a Q control, and a vocal/vowel filter.
• Sphere-Slider and Lazy Mode. The Disrupt Sphere-Slider connects to several delay parameters, and Lazy Mode automates its movement in different directions.
• Audio Follower and modulation. The side chain input drives the Audio Follower, which can influence the Sphere-Slider and other parameters, while the MIDI and MOD 1 to 4 section drives parameters across the plugin.
• Crack, keygen and serial variants. The DelGrain crack, keygen, serial key and working serial are the strings most often typed when searching for this release, and a license key generator is often paired with the plugin name.
• Repack, .rar and .iso builds. The repack circulates as .rar and .iso packages, and a torrent or magnet link is the usual route for the multilingual repack and portable version.
