Slip into a Delay-induced Dream
Granular synthesis, wavetable synthesis, stutter generator, flanger, percussion resonator — it's all here and more in Plugin Alliance’s Unfiltered Audio Sandman Pro Delay. These narcoleptic worlds of delay have led many mix engineers, sound designers, and DJs to praise this plug-in. Sandman Pro kicks it in the dream-ether realm with a wide range of incredible delay modes, seven of which are new in Sandman Pro. But the true secret of Sandman Pro is the Sleep button. This can freeze the delay buffer to forge striking loops and grains that await your direction for intense or subtle modulation courtesy of Unfiltered Audio’s flagship modulation system. Slip into a sonic sleep with Sandman Pro’s tones and textures!

Delay modes upon delay modes
Are other delay plug-ins sending you to sleep? Seven delay modes are unique to Sandman Pro, promising to send you on an explorative daydream of delay-induced excitement. Plus, maximum delay times can reach 16 minutes! Sandman Pro treats you to echoes, loops, and grains with virtual tape saturation in Classic Tape mode. The Multi-Tap mode can make vocals and guitar solos sound massive thanks to doubling and stadium-sized echo effects — not to mention, there are 16 simultaneous delay lines and artifact-free audio. Thirdly, Reverse mode traverses you through the mirror to experience ultra-smooth, click-free, haunting reverse echoes.
Next, Modern Instant mode can modulate Sandman Pro’s delay time without audible artifacts, making it easy to transition a vocal effect from doubling to echo trails at phrase endings. The dual-mono Pitch Shifter can create vocal harmonies, shimmer effects, and glorious metallic textures. On the other hand, a Glitch Shifter mode lets you double down on ultra-funky pitch shifting. If that doesn’t tickle your fancy, try modulating the Sleep button in No Echo mode to really taste some mayhem-induced stutter and glitch effects.
Dreamy modulation capabilities
When it comes time to modulate your sound, you can indulge in Unfiltered Audio’s flagship modulation system, filled with eight types of modulators. Plus, if you have a ROLI Lightpad control surface, you’ll love Sandman Pro’s special modulation mode that seamlessly integrates with the controller. Every control in Sandman Pro can be automated via assignable LFOs. If sine-based LFOs aren’t your cup of tea, you can also modulate parameters with a step sequencer.
Tones and textures found within the deepest dream state
Sandman Pro’s incredible range of tones and textures might keep you exploring this dream-state-like plug-in for hours. For example, with high feedback levels, the diffusion network layers reverb with echoes and multi-tap delays. Ping-pong echoes and phase-induced Sleep-buffer loops are also possible when you offset left and right delay times through stereo delays with a little cross-channel feedback. You can also achieve backward envelopes by reversing the Sleep buffer and transforming the grains. It’s easy to sculpt timbres thanks to built-in lowpass and highpass filters. A Soft Clip function packs analog-style saturation for those vintage-sounding soundscapes. An M/S mode can transform Sandman Pro into a mid-side encoder through Width control that blends mid and side channels. From beautiful to bizarre, Sandman Pro can take your music there.
