mcfx is a suite of multichannel VST plug-ins for MacOS, Windows and Linux (mcfx_convolver, mcfx_delay, mcfx_filter, mcfx_gain_delay, mcfx_meter)
these plug-ins are very handy if you want to process multiple channels in one go for example * multiple loudspeaker setups, Ambisonics (see ambiX ) * Microphone array post productions (eg. Eigenmike®) ….
currently high channel counts per track are only possible with the DAWs Reaper (Win, OSX) and Ardour (Linux, OSX)
