Free Audio Plugins & Softwares for macOS

MIDI Polysher

MIDI Polysher is a free studio tools VST plugin developed by eaReckon. Compatible OS(s): Windows 64b, macOS.

MIDI Polysher is a free VST plugin primarily 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, over the past few years, musicians have shown interest for this plug-in which can be used in other VST compatible DAWs.

This plug-in is a VST MIDI filter that offers the possibility to virtually split your master MIDI keyboard into multiple key and velocity zones.

It also features a transpose option, a MIDI channel filter and three global filters (CC, Pitch Bend and Aftertouch).

Please note that how easy (or even possible) it is to use MIDI Polysher highly depends on the host’s MIDI routing capabilities.

micronAU

micronAU is a free audio and studio utility Audio Unit plugin developed by RetroWare. Compatible OS(s): macOS.

micronAU is an Audio Unit plug-in that allows you to fully control and automate the Alesis Micron hardware synthesizer. As anyone who owns one of these synths knows, it can generate some wicked sounds but it can be a real pain to program via its single knob. This audio unit provides an interface through which the entire sound generation engine of the Micron can be controlled in real time. In addition, all parameter settings are saved when the track/DAW hosting micronAU is saved. When you reload a track hosting micronAU the settings are restored, thus avoiding the “what patch did I use for this track” syndrome. Furthermore, if your DAW supports automation of plugin parameters, all of the Micron’s parameters can be automated and controlled by any of the DAW’s supported control surfaces.

And if that’s too much, you can just hold ctrl and MFreqShifter will only slightly modify existing settings.

Adjustable up-sampling 1x-4x to minimize aliasing and get an even clearer sound.

Easy-to-use user interface. You can easily change all values, fine-tune each control in multiple ways. Easy orientation in a standardized GUI, textual editing and smooth visualization with almost unlimited zooming are standard.

Automatic synchronization to host tempo – every oscillator and modulator in the plug-in can automatically synchronize to the host providing as natural a sound as possible while not offending other tracks.

MIDI controllers with MIDI learn – you can map any parameter to any MIDI controller or MIDI keyboard and control it realtime or record and automate it.

Fully automatable.
