Update for April 13, 2021. We've updated all of our AU's to include better support for saving and sharing presets on macOS. The preset share button will now open a file saving dialog on macOS that will let you export the preset from the app sandbox. As always, to import a preset into the AU, you can drag-and-drop the preset file onto the table of presets in the preset pane. Additional bug fixes have been implemented for the AU's on both macOS and iOS. These primarily have to do with host-AU interactions around preset handling.
Our latest Audio Unit for iOS and macOS, is NeSi xTrem. xTrem is an update of one of our older AU's that has been brought over to AUv3 for iOS. xTrem is a stereo tremolo effect with LFO based FM oscillators. The FM LFO's give you a highly configurable oscillator shape. The stereo channels have independent oscillators, enabling some pretty fun control over the stereo field.
The original version of xTrem was a simple volume based tremolo. This new version maintains that capability and adds a low-pass gate type tremolo. The LPG and VCA based tremolo paths can be freely and independently mixed with the dry signal to yield a broad array of textures.
We are also bringing all of our AU's to macOS. They are compatible with both x86 and Apple Silicon based Macs. These are being ported using MacCatalyst and are available as sandboxed AUv3 implementations. Checkout the Software page for download links.
