Scatterbrain is a plugin audio effect (AUv3, Audio Unit), which chops up incoming audio into rhythmical steps and sends these slices out to multiple outputs in your plugin host.

Scatterbrain has 2 modes:

SEQ mode...
You can sequence how the steps are scattered over the (maximum 4) different outputs, or leave that up to chance.

MIX mode...
You can live-mix (or automate) how steps are distributed over the 4 available outputs and trigger stutter repeats.

Stutter and buffer effects:
Scatterbrain records the incoming audio onto a hidden internal tapeloop. Using the buffer effects you can specify the probability of randomly triggering slicer or stutter effects for an extra seasoning of chaos and mayhem.

Note: to use the multi-out effect, this AUv3 plugin requires an AU host which supports multiple outputs. If the host does not support multi-out, only the first channel will work.

Also note that due to the multi-out nature of the plugin there is no meaningful standalone functionality. You will need a plugin host to make use of this plugin.

Another top notch app from a great developer

One thing I can always count on with any Bram Bos app is that in the first afternoon of enjoying it I always feel that I’ve got my money’s worth. (So future days of enjoyment end up feeling like I’m getting them for free!) Scatterbrain is no exception. Making music by selectively slicing and dicing a single audio stream and feeding each stream to a different effect opens up such musical possibilities! (Especially if you feed one of the streams to a multi effect like Turnado and spend some time going nuts with the random button.) And of course, Scatterbrain has a random button too! Absolutely delightful!

Another dawless jamming essential

... from the master of dawless jamming AUv3 tools! Simple but deep tool for playing multiple effect chains like instruments. Build your own effectrix! Looking forward to using this in every AUM session.
