Parallel compression

How do I send my drums to two separate buss at the same time?
I need to do parallel compression and using a send has latency

    Using a send shouldn't have latency?

    What compressor are you using? - if it has a "mix" control then you can achieve parallel compression with that

    The other option is to simply use a send to a bus that has a lot of compression and blend to taste

    I think we need to trace the source of your "latency" on sends

    What plugins do you have running?

    I would also check that none of your sends are going to a delay bus - I once did this once and the delay was set to 100% wet, which sounded like latency

    this is almost exactly how I parallel compress in Sonar

    There shouldn't be any latency at all. is it possible you are somehow routing reverb (maybe for a snare) to the parallel bus by accident ?
     
    you cant really achieve this effect by using 2 busses, because you need to "Send" some of the original signal to a bus.
    The only way (I know of) to achieve this is by cloning the tracks, then sending them to a different bus. But then your probably going to end up with phase issues.

    Perhaps the "latency" the OP was referring to was the latency within the compressor. Using a Send to a bus, as pointed out above, incurs no latency beyond a microscopic number of CPU cycles.
     
    This would indeed be a problem if not for Plugin Delay Compensation (PDC), which assures that any delay in the parallel bus is duplicated in the main bus, thus assuring that both signals remain in phase. It's one of the many great conveniences of digital recording that we kind of forget is there because it works so well.
     
    Parallel compression can be most easily implemented by using a compressor that features a wet/dry mix control. However, there are times when a separate bus works better because you can then treat the two signals independently, such as applying EQ to the compressed bus or keeping it dry while affecting the main signal with reverb.


    All else is in doubt, so this is the truth I cling to.

    I always create a "master drum buss", and then another 'drum crush buss'.  drum crush is what i call the buss where I parallel compress.
     
    for each individual drum track, I use the track output to route them to the master drum buss.
     
    I also add a post fader send on each track to 'send' to the drum crush buss
     
    I set the output for the drum crush buss to go to the master drum buss.  this is so once I blend in the parallel compressed signal, I can control the level of everything with just the master drum buss fader.
     
    the master drum bus has very light compression just to help glue the kit together.  maybe 3db max of gain reduction with a ratio between 2:1 and 4:1 with a pretty slow attack(30 to 50 ms) to keep the punch.
     
    the drum crush buss has pretty radical compression.  usually 10-12 db gain reduction, at minimum 10:1 ratio, and a fast attack to kill transients and 'round out' the drum and bring its tone out.
     
    when I blend with the mostly dry signal it starts to make the drums sound fuller and with more depth.
     
    I dont always 'send' the overhead or room mic tracks to the parallel drum crush buss because the cymbals sometimes get too splooshy and unnatural sounding with heavy compression.  sometimes it works fine with overheads sent as well, but other times not

    Internal sends should have zero latency. Are you using a hardware compressor?

    I like to create a Drum bus (all drum outputs set to here), then insert a send from the drum bus to another bus labeled Drum bus Comp (add any fav comp.. eg SSL bus comp) set to taste, you know the rest. If you don't want all of the drums or a slightly different drum mix going to the drum bus comp you can always send from an insert on each drum channel to to the drum bus comp. I typically like the ease of just inserting a send from the drum bus. Also, as Bitflipper mentioned the compressors with the wet dry knob (like pro channel) make quick work of parrallell bus compression without eating a bus. Peace!
