Bastl Instruments

Flexible Stereo Space Delay.

Basil is a compact, yet flexible, digital stereo delay module built on the Bastl Pizza platform. It offers clean delay, as well as lo-fi flavors, and its Space section opens the doors to exploration far beyond simple delay territory. The Basil delay buffer modulates really well, allowing to recreate most classic time-based effects, such as chorus, flanger, vibrato, pitch shifter, reverb, and stereo widener, among others, and navigate between them with just a few performative gestures.
