For those people who need a VST host (chainer) to be able to use several VST plugins at once, but for some reason don't have or don't like
Art-Tekhnika Console (which is getting quite old and is not updated any more), they can use
Blue Cat's MB-7 Mixer (stereo version).
I found out (by using "Bit-Compare" function in Foobar and converting from FLAC to FLAC while activating the processing with this Mixer) that if you switch it to 1 band mode, it deactivates any active crossovers in it, and this Mixer becomes a very good chainer (in 1 band mode it does not change sound at all if there are no activated plugins in it, so it's
truly lossless in this regard. While in 2, 3 or 4 band mode, it still changes audio due to crossovers, even if there are no active plugins in it).
So, once you install it, choose "1 band" mode (circled in red) and click on the button circled in yellow. it will give you two more additional slots for plugins (yellow). Otherwise, you will have only 2 slots (green).
Blue Cat has another plugin, which is a proper chainer, it's called
Blue Cat Patchwork. So, you may ask why use MB-7 Mixer? Unfortunately, you cannot hook up Parchwork to Foobar, because it has lots of input channels (it's designed to work with surround sound) and they are wired weirdly, neither
George Yohng's VST Wrapper, nor
Foobar VST adapter can recognize it (more about this problem of incompatibility
here).
