Read full descriptionHide full description
Concept: “shortReverse II” is the advanced version of “shortReverse” which was previously released. The second has the same functionality as the first but resolves professional needs, that is, the problem of restricted buffer size (2^N). Now the user can freely adjust the buffer size from 256 to 65536 (in 1 sample unit). Usage: The user can reverse an incoming audio signal in real-time only while pushing the button. "buffer size" slider is text-editable by clicking. Note: Button automation in DAW is not supported. System Requirements: AUv3 host stereo output: just plug headphone/mic or audio interface.
Groovemaker

Groovemaker contains two audio unit effect plugins: Bouncer and Freezer. You can load them into your DAW or other audio unit host. But more than a pure container app for the two plugins, Groovemaker is a fun and inspiring tool in itself. Use it to experiment with audio loops in a simple way, on your iPhone, iPad or Mac, on the bus or train or at the beach and export sketches to pick them up later in your DAW and studio.
