bigramp Posted November 19, 2007 Share Posted November 19, 2007 Hello the manual don't give any info about the new compressor's modelisations in LP8 ... Platinum, ClassA_R, ClassA_U, VCA, FET, Opto ... what to expect from each ? did anyone compare it to stuff like UAD's top notch emulation ? thx Link to comment Share on other sites More sharing options...
Jope Posted November 19, 2007 Share Posted November 19, 2007 Right, some more information would be nice, also about the extended parameters, especially distortion. But I think you would have to try them out anyway... Most important is how they sound. Link to comment Share on other sites More sharing options...
bigramp Posted November 19, 2007 Author Share Posted November 19, 2007 ok maybe i should ask everyone which setting you use the most ? i'm looking for a natural sound to compress a drumkit bus... thx Link to comment Share on other sites More sharing options...
teta Posted November 29, 2007 Share Posted November 29, 2007 yes, it would be nice to get some info about the compressors. especially the output distortion option: im compressing this kick drum and i have the output distortion set to Soft, if i move the gain slider up, volume goes louder but the channel level meter stays at the same level and doesnt go red even if i whack the compressors gain slider right up. when one should use these output distortion options?

Brinnbacka Posted November 30, 2007 Share Posted November 30, 2007 ok maybe i should ask everyone which setting you use the most ? i'm looking for a natural sound to compress a drumkit bus... thx Well, I'm mostly using the analog tape compression but it surely is far from natural, if your natural is same is mine.. transparent. But I dig the sound of that tape compression for drums. Just try out the presets, see which one does what you like and go from there. Link to comment Share on other sites More sharing options...
sayenex Posted November 30, 2007 Share Posted November 30, 2007 Tape compression? which one is that? Link to comment Share on other sites More sharing options...
rob glow Posted November 30, 2007 Share Posted November 30, 2007 I can tell you which it *isn't* by process of elimination: VCA = voltage-controlled amplification FET = field effect transistor (used in MOSFET amps) Opto = (most likely) optical semiconductor My guess is that the ClassA _R & _U are tape compressors, or at least one of them is, a Class-A compressors are generically analogue. I could be wrong here, as I don't know a great deal about real-world compressors (only the software plugin type ) Any info on the Platinum and ClassA compressor settings would be appreciated!

Jope Posted November 30, 2007 Share Posted November 30, 2007 VCA = voltage-controlled amplification ... Or Voltage Controlled Attenuator (doesn't matter, since mathematically spoken attenuation is and amplification by factors <1). Funny name, since every compressor contains inevitably a section with variable amplification. They only differ in the components used for this purpose. FET = field effect transistor (used in MOSFET amps) One of the possibilities. A field effect transistor changes its channel resistance depending on a control voltage. Opto = (most likely) optical semiconductor Or maybe a photo resistor. The control voltage makes a light source (light bulb or LED) glow more or less bright, and the light influences the resistance of the photo resistor. Light bulbs and photo resistors are quite laggard (aside from the attack and release settings). My guess is that the ClassA _R & _U are tape compressors, or at least one of them is, a Class-A compressors are generically analogue. I could be wrong here, as I don't know a great deal about real-world compressors (only the software plugin type ) Any info on the Platinum and ClassA compressor settings would be appreciated! Well, I think some special tests would be helpful to understand the different settings. Maybe I will create a test song when I have got some spare time (i.e. most likely never). For this test, I would use sidechaining as it allows to separate the control section from the VCA section. I would feed a triangle wave into the compressor as you can see nonlinearities immediately and then send bursts of 1kHz sine waves with (from burst to burst) increasing amplitude to the sidechain to watch the dynamic behaviour of the control section/simulated laziness of components. The bursts and the breaks between them must be long enough to allow the result to settle. Maybe anyone else wants to seize these suggestions...

fader8 Posted February 5, 2008 Share Posted February 5, 2008 the manual don't give any info about the new compressor's modelisations in LP8 ... Platinum, ClassA_R, ClassA_U, VCA, FET, Opto ... what to expect from each? We really can't expect the manual to teach the craft behind this stuff. If it did, it would easily be twenty times longer than it already is. The link David provided to the UAD article gives a good overview of the various technologies used over the years, but it doesn't provide much info on usage. It's easier to get to know these based on their limitations and how they sound. For example, the class A, aka variable-mu, tube designs have a soft, fixed knee and a characteristic hysteresis. These tend to color the sound though. The Manley stuff is a good example. The Logic 8 compressor doesn't attempt to emulate any specific model, but it does a pretty good job emulating the basic sound and limitations of those technologies, with some added frills, making it a very versatile plug-in. i'm looking for a natural sound to compress a drumkit bus... Typically, that would be the VCA style. While all compressors have a VCA, this style refers specifically to integrated circuit VCA's which are much more controllable and transparent than their discrete counterparts. There aren't any hard and fast rules for the use of these things. After a while you start to get used to what is going to sound best on what.

davidpye Posted February 5, 2008 Share Posted February 5, 2008 I don't think any are modeled on tape compression, tape compression wouldn't have an attack and release time etc etc. It's more like brick wall limitation. At least none of them sound like tape compression to me. You know the cheapest way to obtain cheap genuine tape compressions is to go buy an old reel to reel machine, the likes of which you'd find for about £150. They're cross platform as well you know, compatible with all audio interfaces without need for drivers or updates, and work on protools, logic, cubase, nuendo, you name it.

Saturation is similar to what is termed compression since higher levels are reduced. Of course saturation means nonlinear behaviour, distortion that adds artifacts to the overtone content. If you like, you can think of saturation as compression without attack and release times; the change of amplification occurs immediately for every moment of the waveform's displacement from zero. You can use saturation for reducing dynamics and thickening sound, if you just don't want it crystal clear. Link to comment Share on other sites More sharing options...
