Indeed, digital mixing needs a learning curve that isn't needed for
analog mixing. An analog mixer provides a trim pot and an EQ, but no
effects for each channel, for effects there are inserts and pre and post
fader aux sends. Most people don't own analog mixers with automation.
Users of Linux DAWs should by default add and activate (even if it's
bypassed) FIL-plugin [1] for each channel. And care a little bit about
old school audio mixing. E.g what's the mind of using a compressor for
each channel and fading in and out and in and out during a song?

All you need is FIL-plugins parametric EQ post effects, pre fader, not
completely equal to an anlog mixer, but exactly what's needed and can be
done for e.g. Qtractor's mixer.


There's one plugin in this first release, a four-band parametric
equaliser. Each section has an active/bypass switch, frequency,
bandwidth and gain controls. There is also a global bypass switch and
gain control.

The 2nd order resonant filters are implemented using a Mitra-Regalia
style lattice filter, which has the nice property of being stable even
while parameters are being changed.

All switches and controls are internally smoothed, so they can be used
'live' whithout any clicks or zipper noises. This should make this
plugin a good candidate for use in systems that allow automation of
plugin control ports, such as Ardour, or for stage use." -
