Voxengo - Sound with a Soul
Professional VST PlugIns and
AU PlugIns

Voxengo SPAN version 2.1 update is now available for download.  SPAN is a real-time “fast Fourier transform” audio spectrum analyzer plug-in for professional music and audio production applications.  For the most part it was derived from Voxengo GlissEQ dynamic parametric equalizer and reproduces its spectrum analysis functionality.  SPAN conforms to AudioUnit and VST plugin specifications, and is available for Mac OS X (v.10.4.11 and later) and Windows (32-bit and 64-bit) computers.

List of changes in version 2.1:

• Global options saving problem fixed.
• Clicking on the control surface now resets spectrums in all channel groups.
• "Show All Channel Meters" duplicate meters issue fixed.
• Incorrect spectrum's power readout on zoom-in fixed.
• Incorrect correlation metering on anti-phase signal fixed.
• Graphics drawing performance improved considerably.
• Scroller positions are now preserved when the user interface closes.

• Internal channel routing
• Channel grouping
• Preset manager

As a side note, Voxengo MSED and Voxengo Tube Amp plug-ins were also updated to versions 2.3 and 2.2, respectively, with fixes to various issues implemented and new features added.

In the "Stereo Mastering" preset, shouldn't the "Right" group have the "Left" group overlayed?

It's not necessary since basically you do not need to switch between groups when using this preset.

Ok ;)
