The ecosystem of natively supported plug-ins for BLOCKS has launched with a bang — a stretched-out, distorted, echo-chamber bang that could add a cool layer to your next track.

Cutting-edge plug-in developer Unfiltered Audio has released Instant Delay and SandMan Pro, the first two plug-ins to natively support BLOCKS. That means a seamless plug-and-play experience when you connect BLOCKS with Instant Delay via DAWs like Ableton Live, Logic Pro X, and Bitwig.

In celebration, Instant Delay (worth $49) is now free for all BLOCKS creators! The plug-in is a powerhouse for echo and delay-based effects. It’s built with Unfiltered Audio’s “Modern Instant” delay mode, which among other things lets you create cool time-stretching effects and varying delay tails by shifting the delay buffer in real time. Filters and saturators let you dial up tons of tone and character.

It already has a cult following, and now SandMan Pro is natively integrated with BLOCKS. The flagship delay unit from Unfiltered Audio is stacked with advanced effects like stereo pitch shifting, reverse echoes and frozen delays. It has a powerful and intuitive modulation system that lets you create and tweak any delay effect you could possibly imagine — in real time.

SandMan Pro is now available for $29 for anyone who has a Block. That’s a deal compared to its usual price of $99.

These Unfiltered Audio promotions give BLOCKS creators the chance to get their hands on $148 worth of top-quality Unfiltered Audio plug-ins for only $29. Both promotions runs for six months until November 25. Don’t delay. Follow the instructions at the end of this article to learn how to download Instant Delay and SandMan Pro.

This is just the beginning of a very cool collaboration. Unfiltered Audio will be re-releasing all of their plug-ins for BLOCKS over the next few months. Fault, Dent, Indent, and others will soon be plug-and-play on BLOCKS. They’ll put all kind of new sounds and effects at your fingertips, and you’ll be able to easily assign gestures on the Lightpad Block to any parameter in the plug-ins.

We’re proud of this collaboration not only for the cool sounds that are coming, but also as a great example of how developers like Unfiltered Audio can quickly build native apps and plug-ins for BLOCKS with our BLOCKS Developer Kits.
