What RP-Delay does
Basic delay models such as simple mono delay and stereo delay are included in addition to the more complex structures. Delays, filters and the reverser can each be modulated by the built-in modulators, which comprise four modulation sequencers, four LFOs and four envelopes, with several trigger options.
The reverser takes the input and reverses it while simultaneously reversing one of the delay lines, and the reverse sound can be triggered from a MIDI keyboard to produce new material. The plugin is packed as VST2, AU and AAX for Windows and macOS, and a crack, keygen or serial key search often pairs it with the name, while the repack circulates as .rar and .iso and the macOS build as a .dmg crack, with x64 crack and win/mac crack also in use.
Key features
- Six delay lines. Six delay lines operate at the same time, each with its own routing within the delay section.
- Eight multi-mode filters. Eight filters with several modes are active alongside the delay lines, so the delayed signal can be shaped in several places.
- Reverser section. The reverser reverses the input and, in the same pass, reverses one of the delay lines.
- MIDI-triggered reverse. The reverse sound can be triggered from a MIDI keyboard, which produces new sounds from the same delay structure.
- Modulation sources. Four modulation sequencers, four LFOs and four envelopes modulate the delays, filters and reverser.
- Trigger options. The modulators offer several trigger options, which set how they start in relation to incoming audio and MIDI.
Compatibility
RP-Delay is available as VST2, AU and AAX for Windows 7 and later and for 64-bit macOS. Activation uses a serial number, and a trial is available.
