OkChorale Chorus / Vibrato Plugin (AUv3) OkChorale is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic or GarageBand. Overview OkChorale is a stereo chorus / vibrato effect inspired by classic analog stomp boxes. While not intended to be a model or replica of a specific unit, the processing and features embrace a bygone era of simpler times! Both chorus and vibrato effects are achieved by modulating the time of a delayed version of the dry signal. Typically, these delay times are very short, between 5-20ms. Parameters Active - Toggles the effect On or Off. Rate - Varies the modulation LFO frequency between 0.1-10.0 Hz. Typically, chorus sounds better with slow modulation, and vibrato is more noticeable and natural with higher rates. Depth - Sets the amount of delay modulation, as a percentage of the maximum modulation delay time. Mode - Toggles between Chorus and Vibrato mode. In Vibrato mode, the base delay time is very short and no dry signal is present in the plugin's output. In Chorus mode, the delay time is longer, and the dry signal is mixed with the delayed version. When used in stereo, the left and right channel's modulation is out of phase to create a wide stereo effect. The modulation wave shape is also different, depending on the mode. In Vibrato mode, a sine wave is used. In Chorus mode, a slightly rounded, and more "analog-like" triangle wave is used. Despite the basic design and lack of features, we hope you agree that OkChorale can still sound pretty OK! If the name sounds familiar, OkChorale is a version of the OK CHORALE module developed for Voltage Modular by Waverley Instruments.

Construct evolving sequences. The creative experience of using a constrained hardware system rather than the lazy freedom of just being able to “add another module”. ThreeTuring lays out everything in front of you without the need to keep going back to the manual. No menu diving, no alternative pages and easy to pick up if you haven’t used it for a few weeks or months. Having fun making music. ThreeTuring consists of a dual oscillator monosynth, a clock module for generating trigger patterns alongside a collection of generative modules encompassing a range of modular generative techniques including a turing machine, random generators, LFOs, envelope generators, a quantiser, a note accent and a set of effects modules. Pretty much every control can be modulated via the nine slot modmatrix, including the modulation settings themselves.
