You will not regret it - Quinto makes some wonderful plugins & I am sorely tempted to try his hardware units because of they have half as much attention to detail they will be awesome.
His Strip/BUS tool has a steep learning curve - it allows stuff neither Slate nor Waves offer and that is a true emulation of a console complete with all the drawbacks as well if enabled. Don’t get me wrong, I love the Slate tool - it is so simple to use there is no good reason not to use it and the cumulative effect is quite something (I hear very little difference on a per channel basis, but to give a test try setting all drum tracks as follows:
1 - Select all drum tracks, hit Q-Link (if using Cubase/Nuendo)
2 - Insert the VCC on each track as second insert
3 - Set to Neve mode, disable Q-Link and create your drum mix (use a subgroup to sum the tracks if you wish - I generally set up 2 groups, one straight & the other for parallel drum compression).
4 - When happy, re-enable Q-Link and play the drum mix, switching between Neve & API modes on any track - Q-Link will (or should) switch the rest at the same time.
I selected those consoles because the difference is very obvious but experiment with others.
The Waves NLS is also very good at what it does & is a little more flexible in VCA routing and often works well on mixes where the VCC doesn’t quite sit right, probably because it models different boards as does the Sknote one.
I like all 3 very much.
Oh - when checking out Sknote, don’t forget to try these as well:
http://www.sknote.it/C165a.htm - a great model of one of the fastest compressors ever built, and
http://www.sknote.it/GTS-39.htm - colourful as all hell, and a lot of fun. Just don’t expect clean output!
