Oktabep

The Oktabep VST3/AU plugin is a simple polyphonic octaver effect.

With its quick and intuitive UI, the plugin generates up to four polyphonic octaves from the incoming signal (two upper octaves and two lower ones). Low- and high-pass filter switches allow you to shape the resulting sound. Of course, you can combine this with any other effects in your signal chain for an even broader sound palette. The Oktabep tracks even the most complex signals perfectly, allowing you to quickly inject upper and lower octaves into the mix.

The plugin was mainly designed for guitar and bass, but you can certainly use it with any signal source. Experiment away.

The Oktabep is also available as a standalone app which doesn't require using a DAW.

The Oktabep VST3/AU plugin is almost an exact copy of the Shift Line Oktabep pedal's algorithm. The key difference is that you can use the plugin in your favorite DAW with the sample rate and bit depth of your choice.
