Deja vu all over again?
I am afraid my only tip for mastering tools is 'TURN THEM OFF!' If the arranger sounds like cr*p without them, that's not a good sign....
Look, I do mastering work at my home studio and also at a large commercial facility in my home town. They have a Manley Slam! (mastering edition), Manley Massive Passive (mastering edition) and hardware Waves L2 Ultramaximizer limiter (DON'T confuse it with the software L2's!) through B&W monitors in their mastering chain, at home I mostly rely on UAD plugs and some Waves things (C4, mostly) through Mackie HR824's to do it here.
And the one thing I have learned is, if the mix isn't any good to start with, you are just turd polishing (to use an industry expression!). In other words, the mastering part of the process is just there to 'glue' the mix together a little bit, and help raise it's level to the absurdly high RMS levels that modern CDs are mastered at (don't get me started on this one!
). It isn't supposed to be 'corrective' at all if it can be helped.
So I say to all of you out there with sonic problems, or auditioning new gear... TURN OFF THE MASTERING SECTION...! Listen to the arranger without any of that stuff messing with the basic sound. Of course, be sure you are listening to it through good speakers (we'll deal with getting the on-board speakers to sound better later), or top quality headphones (try Grado's... to die for!). Make sure that your ears are rested, you are calm and focused, and bring along a CD of a well recorded piece of music that is appropriate to the style you are going to play, and that you are very familiar with.
Try to get the store (if you are in one) to jack this CD through the same speakers you are listening to the arranger on (if it has RCA inputs, even better, just connect the CD to the arranger). Now start to listen and compare...
Do you feel the arranger feels full and balanced compared to the CD? A CD of you playing your LAST arranger is ideal, if you have one. Now you can truly see how much better (or not!) this new toy is compared to the old one, and objectively, too.
Now listen to the balance of the arranger. Does any one thing sound out of whack, or is it EVERYTHING? One of the commonest problems many have with EQ is that they will use Mastering EQ to fix a problem with just the drums, or the Bass, or the piano sound. That's what the per-part EQ is for! If you use the Master EQ, you stick that curve on everything, whether it needs it or not. Mostly, NOT....
So..... I think you are beginning to see what I'm getting at, See whether the arranger sounds good and un-hyped without the Master tools. The styles come next....
WITHOUT the mastering EQ and compression, do they sound consistent? Are they similar in volume? Are some bass-y, and some thin? Here lies yet another problem with the Mastering Tools. Are the styles developed with the tools on or off? And are they all developed by the same team, with the same settings? No way to tell....
But if there ARE some wild swings in balance, that's a probable culprit. But let's assume for right now that they are reasonably consistent.
So now you are listening to the arranger, through hopefully a flat PA system, or good headphones. Now turn on the CD. Any big changes in EQ? More bassy, less bassy, too much middle? Hopefully not, but if so (and the styles sound balanced), NOW is the time to use a LITTLE EQ to try and match them a bit closer. OK, let's assume that's done....
FINALLY, now is the time to turn off the PA and change over to the Internal speakers.... Take a few minute's ear break. Now come back and listen to the speakers. Do you hear any noticeable EQ shifts? Now is the time to apply the separate speaker EQ (if it has one) and try to get back to roughly the same tone balance as before, but always consider that you are going to be very lucky to get the depth of bass out of little speakers. Warm it up a bit, if necessary, but don't overdo it. You can't get a quart into a pint jar....
Hopefully, by now, you have a much better idea of what the arranger's TRUE sound is like, and the CD comparison will help you avoid the sin of over-hyping the EQ.
I'll deal with compression later, but suffice it to say, once again, if the arranger needs it just to sound good, that's a bad sign. They ARE useful in low to moderate amounts to stop you from breaking up the Internal speakers, but never at the cost of pumping or breathing (read an article on compression if you don't know those terms).
Sorry to all the pros and knowledgeable amateurs that already know all this stuff, but I am surprised at how many times I've read a post, or listened to a user demo, and immediately heard that the EQ and comp settings are WAY hyped, and fighting the sound. Just keep saying to yourself... Less is more..... Less is more..... Less is more....
