High Pass, Low CPU

I'm looking for a solution for something I want to do, which is have a High Pass filter on every channel in my default template, turned on by default.
 
I know I can use the ProChannel EQ to do this, but I find it takes up too much CPU for such a simple task. Also, I'm going through a phase (no pun intended) where I'm staying away from ProChannel. It's just not fitting my workflow.
 
So again, can anyone recommend a low CPU, simple, but quality High Pass filter that would work well as a staple in my stand art template?
 
Thanks!

Gavin

IF you want that filter everywhere, does that mean that you have an excess of bottom end everywhere?
 
I do tend to put on a high pass whenever I record acoustic guitar just to grab the little thumps that players inadvertently give the top of the guitar when they don't mean to.
 
I'm curious.

Hey Ampfixer!
 
Good question. I'm one who likes to High Pass in order to clean up the bottom end. Of course I wouldn't use it for every track I mix, but I find it's easier to turn it off on a few tracks than to create it on most tracks.
 
This is for a MIX template, not a tracking template though.

I just discovered the FabFilter Micro!
 
I love this thing! Not only a great Hi Pass, it allows for some very creative shaping!

You could route all the tracks requiring high-pass to a bus with a single instance of whatever filter you like at very little CPU cost.

That's really good advice, not so much because it's a traditional steep highpass filter, but because the resonance options let you get more mileage out of its "highpassness." For example, you can use it selectively to get rid of most of the lows, but boost the upper lows or lower mids a bit so you have the option to "warm up" the sound while also cutting out the lowest frequencies. CPU consumption is modest.
 
While maybe not exactly what PilotGav wants, for some signals it could be a better choice.

I wouldn't do that - you want to do HP filtering to take out the rumble at the start of the chain, not at the end ... so I recommend to make use of the low cut button on the pre-amp if recording signals that don't go that low.
 
I never found ProChannel to be resource intensive (use it basically always on all channels, frequently just as a simple low cut). However, there are times when EQ needs to be after FX - there I either insert an EQ plug at the end and keep ProChannel at the beginning, or use BOZ Bark of Dog as simple (sometimes resonant) low cut and keep ProChannel for later ...

Be careful with Micro, or any other filter that isn't completely transparent. Transparency is what you want in a HPF. You don't want to be able to hear it.

I just had an idea (gosh i'm a frikkin geenyous)
 
Mixers have low cut  (hi-pass) buttons on each channel. Not like the gui needs another button but how 'bout that? - about 100hz is it?

The only problem is the ones in mixers aren't as helpful as you might want, because they're limited by being hardware - the frequency is usually fixed and the slope isn't all that steep. The Sonitus EQ or ProChannel EQ is more flexible. You could always create a template that has a Sonitus EQ set for the desired preset in every channel.

I have a Focusrite ToneFactory back in the UK. That was my first intro to haveing both a sweepable high pass (up to 320 I think) and a resonant bump (switch in and out rather than continuous). That really opened up the bass end when all I had was Spirit folio mixers. 
 
There's a feature request for a low and high pass option somewhere in the history. All the time the Pro channel eq is fixed in the chain, I can't see there being a need for it. High and low pass on sends however I think would be welcome (there's another feature request for this too). To help sculp sounds going into reverbs and parallel set ups.

I love the idea of ProChannel and have used it exclusively in the past... however I just find that I have a mental block somehow due to the interface/workflow. One example of many is that if I expand the EQ, it covers up the MSR buttons. I know this seems small, but its just little interface quirks like this which have turned me off it.
 
It's a shame because in concept it really is awesome. I just think it needs a huge interface/workflow overhaul.

On that one aspect I agree with you and I believe there's already a Feature Request to have the MSR buttons visible on the fly-out.

You can dock the ProChannel on the other side of the track view.

Off topic, but thanks for bringing that tip to my attention - it just helped to save a vocal track that was fine except for a couple of plosives in one verse and wouldn't have been easy to rerecord!

You can also float the ProChannel so that opening the EQ doesn't cover up MSR

Thanks :-)


the sontius suite still has its uses. trust me.
the QC EQ I use for almost all my high pass and low pass filtering. for three reasons:
1- because it is low on CPU's
2- because its easy to set up
3- and most important it does the job well.
im not a huge fan of the rest of the QC EQ believe it or not, but the LP + HP functions you cant beat.
I typically still use at least 1 sonitus plug in on almost every project.
 
yes there are better PI's out there, but once you've learned to master a tool, you use it to its highest potential.
that's sonitus. ive been using them so long, ive squeezed every once out of them.
 
I would just give the QC a shot. (you probably have) but if not...try them out.

I forget about the Sonitus.  The QuadCurve is right there in the PC, which is probably why I mostly use it to HPF all the tracks.  What I probably should do instead is use two Fx Chains, with the Sonitus as a HP filter in the first one and then the QuadCurve would be available should I need it later on in the signal chain.  Sounds like a new PC Preset option.  I rarely use the Fx Bin anymore.
