    Hi everbody,
    I have a simple question. I'm using Logic on DAW and I would like to buy some Lexicon reverb. I mixed my drum tracks on a stereo bus and would like to exit (D/A or digital) to a reverb for having reverb on drums.

    The only request is that I would like the reverb of my 12" tom to be on the left just like its original panning. That is I would like my panning on drums to be kept even after reverb, and not having it all pushed to the center (even if beautifully stereo).

    Do I need a true stereo reverb? dual reverb? (btw what does this mean?)

    Which one of the reverbs in subject is right for that?

    Thank you,

    Any of those you mention would work fine. The PCM90/91 is of higher quality than the rest. Dual reverb is most cases means two mono inputs into two reverb algorthims (same or different) but both use the same stereo output. In some units/presets it may also be dual mono output. You can use just one output of any reverb and pan it to one side or wherever you want.

    Reverbs are usually stereo, and any one sound (like a tom tom) in a large room will be (essentially & argueably) mono but the natural room reverb will be stereo ..

    I pan toms left to right and add verb ... the tom hits are mono (panned) but the reflections are stereo ... just like in the real world..

    :) The PCM 70 is a mono in, but definately stereo out, it has full control of time, pan, level and repeat of of 7 pre-delays. The early reflections created with these present some very good and realistic space, but the stereo verb programs vary on the type verb you use. Plate, hall, chamber, etc.

    They are programs with many adjustable features. The Gaff loves his Eventides...but I did see some Lexicons in his racks. I think the later models have cleaner sound, and even more convincing space creation. Darn, this thing has been running since the mid 80's. No fans, vents or anything for cooling in a sealed case. Worth every penny of it's original 2k cost, got my use out it for sure.

    Thank you guys,
    ...does this mean, that I could buy a PCM 70, feed it with my summed to mono stereo drums mix and I would obtain exactly the same effect of a PCM 90 fed with the stereo drums mix (except for all quality and preset differences and speaking only of the reverb-processed part of the signal)?

    I'm just trying to find the right way to minimize the reduction of spatiality I get when I add reverbs...

    Thank you again.

    :) Gaff says it all here, I say, not necessarily, for example, let's say you want a nice room reverb sound on the main kit (input one). But on the snares rim shot you want about a 60 to 80ms pre-delay and a longer decay than the rest of the kit (input 2). The outputs of both the combined verb outputs would be providing a left and right. This would be convenient for a real-time mix. But if you isolate tracks, the same effect can be achieved with a single mono input unit, only it would take 2 passes, and 2 pairs of left/right additional reverb return tracks to be combined in your mix. Sure, dual has its advantage, and perhaps some newer verb programs. Just because it is dual does not mean it will create any more of a realistic sound field. From the perspective of a stereo drum mix, how would the verb know where to generate a soundfield that compliments the kit, and convinces the brain?

    I added this later, my 70 allows the unit to operate downstream with the wet/dry mix control, this would benifit a single source. I would imagine the 90/91 allows the same, however your panned drums will maintain the spread, only stereo reverb will be added. In a console configuration, the verb would be set to 100% wet, and controlled with the sends and returns. In a stand alone, or channel insert, then the mix controls would be a must, on either the 70, or 2 channels on stereo subgroup inserts for the 90/91.

    There are times and have been many times when I only use one of the outputs of a stereo reverb because using both is just sometimes too much of a good thing. it may end up in mono or panned to one side or anything in between. Am I missing some of the stereo reverb sound/information and it's attempt at realisim? Ya. So? It still sounds better to me sometimes.

    And as much as I love my three Eventide's, I still usually prefer to use them for other things than reverb and rely more on my Lexicon M300, PCM91 and TC M5000 for reverb chores. I'd still have my PCM70 also but I took the $1300 offer a client offered me a year ago and bought an another API compressor.
