MIDI Polysher

Virtual Patchbay by eaReckon

Free Product

MIDI Polysher is a free VST plugin primarly designed for eaReckon BloXpander users (but it works with other compatible VST host software).

BloXpander is now provided with its own full-featured MIDI filter and therefore, BloXpander users do not really need this plug-in anymore.

However, musicians have shown interest for this plug-in which can be used in other VST DAWs.

This is why MIDI Polysher was rebuilt from scratch and it is now available as 32/64-bit VST plug-in for both Windows and Mac OSX.

With multiple instances of MIDI Polysher loaded into your DAW, you can create "zones" and control several instruments from a same MIDI keyboard (or controller).

For example, you can link the upper keys of your master keyboard to a virtual piano plugin and the lower keys to a virtual bass instrument but there is more to do with it...
