      Comments about Lexicon MX400 Dual Stereo/Surround Reverb Effects Processor:

      I just picked up one of these over the holiday and was super excited. It was relatively easy to set up using spdif for the audio. I use Ableton 64 bit and was surprised that after installing the MXedit software i did not see them show up in my plugins folder. Then I thought of course I can use JBridge to use these plugin because they are probably 32 bit. As you all know JBridge only works on vsts. I ran it found vsts for mx200 and mx300. Turns out there is no vst for mx400 and there is no free bridge interface for AU.

      Contacted the manufacturer and this is the response I got:

      Robert,

      Unfortunately there are no plans at this time to update MX-Edit to 64-bit. We do not have a VST version of the plugin for the MX400, AU only on MAC.

      Sorry it's 2013 everyone has already or is moving to 64 bit. This could have been a nice addition to my studio...

      Comments about Lexicon MX400 Dual Stereo/Surround Reverb Effects Processor:

      Virtually everybody who buys a multi effects unit uses it in a superficial way. It's the same old: "I bought this for the reverbs and delays and they're awesome". What about all the other stuff! That's why you see so many reviews praising this unit and not mentioning the hidden limitations, lack of info in the manual, and bizarre behavior of the thing. I've only had the unit a few days and here's what I've learned about it that you won't find in the manual or in other reviews.

      BAD POINTS:

      One of the main reasons for buying the MX400 (or MX300) over the MX200 (or two MX200's) is for more parameters to adjust for each effect, rather than just the three the MX200 limits you to. To my shock, those extra parameters only show up when you're running just a single effect in one of the engines. As soon as you dial in a routing setup that uses two effects at once, all those in-depth effects parameters disappear and you're bumped down to the same three per effect as in the MX200. So if you want to run all four effects at once, the MX400 turns into two MX200's under one roof, but without the MX200's ease and speed of patch creation. If you want the extra effects features and parameters, you'll have to limit yourself to just two effects total on the MX400. This is unacceptable and totally deceptive and of course not mentioned in the manual. Not why I bought the MX400.

      Adding to the above, the reduced set of parameters per effect also means missing functionality even when it's using the same knob. For example the phaser and flanger lose their ability to do negative feedback, the phaser rate gets limited to a slower rate (not even fast enough to do opening to Gary Numan's Cars), can't select number of phaser stages, two voice pitch shifter becomes one voice and loses it's feedback delay, etc.

      The MX400 manual lists Arena and Studio reverbs, but they aren't available when running a single effect in an engine. They only appear in the menu when changing to a dual effect routing. Just the opposite for the 2 Tap Delay, which disappears altogether when running a dual effect routing.

      A written manual is supposed to tell the user everything about a piece of gear. Not so with the brief MX400 manual (Lexicon's manuals have been going downhill with every new series they release). For instance, the Chorus can be set to 99 voices. But it's not really a 99 voice chorus. So how many voices is it? The manual won't tell you. Had to look back to the MX200 manual to find that the MX400 probably can go to 8 voices. How are those voices positioned in the stereo field and are they in some kind of phase with each other or free running? Even the MX200 manual doesn't say, so I had to go back to the MPX100/MPX500 manual to find out. Does the pitch shifter detect pitch and want only a monophonic input? Had to go back to the MPX100 manual. How many stages is the phase shifter when in reduced MX200 edit mode? Had to do a side by side listening test between MX400 and MX200 to find out (appears to be 8 stage). Can patches be named on the MX400 or do you have to use the PC editor? I had to buy the unit to find out because the manual wouldn't tell me.

      EFFECTS GOOD & BAD:

      (Flanger) Unlike everybody else, Lexicon provides through zero flanging (or a simulation of it) and also negative and positive feedback. Growing up on Tomita, this is what I want. However, if you don't want that climax and near sound canceling result, it doesn't seem like you can get away from it. There is no manual parameter for setting the center freq and no way of stopping the sweep altogether and using it as a fixed comb filter or resonator.

      (Phaser) Also provides negative feedback as well as positive which is rare and can be set to 4,8,12 stage, but as above, no manual freq control so no fixed comb filter.

      (Pitch shifter) Faster response time than older MPX100/500 units, but just about as lousy sounding. Held mic up to youtube video for some solo instruments playing and it sounded halfway decent until orchestra came in, so I thought maybe it was detecting pitch. But after plugging in a synth and running clean tones through it, it sounds lousy on some monophonic notes. So far TC Electronics and Lexicon have the worst sounding pitch shifters of any gear I own. Roland and Behringer do better in this department, though they all are somewhat lousy. When the delay/feedback option is available, you can create rising or falling pitch shifted sounds. Unfortunately Lexicon didn't give enough feedback amount, and the sound dies off too soon. The older MPX100/500 were far better at this IIRC.

      (Delays) There are a number of them and with something like the Tape Delay, I was hoping that one could rotate the delay time knob and speed up and slow down the delay like on a real tape (or analog) delay. You can, but it introduces glitches or bad artifacts making it useless for that kind of thing. I have a lot of free VST plugins that can do that just fine. As owner of a Lexicon PCM-41 I was hoping the Modulation Delay would allow all kinds of extreme stuff like massive sweeps or square wave modulation, but no. The mod amount knob only gives a mild chorusing sound to a delay.

      QUAD UNIT or just DUAL STEREO:

      The MX400 is basically two separate stereo units under one roof. One engine has no clue the other one exists. That means you can't use all 4 effects on one stereo input/output. You'll need to duplicate inputs and mix outputs, or if you want to run 4 effects in series, you'll need to plug MX400 outputs into other inputs. Patches don't save all 4 effects at once, you have to load each half separately. Seeing how the surround reverb can use just 2 inputs and output to 4, it seems like had Lexicon not been lazy, this could have been a more flexible stereo unit utilizing 4 effects at once. The surround capability almost seems like it's there just because they could. There is just one hall algorithm and nothing else. Even just a quad panning effect would have been nice. Would like to have seen a global LFO on this unit for modulation effects in sync.

      FINAL:

      So the MX400 is a mixed bag of good and bad. I wish companies would put more pride and thought into their products rather than just repackaging the same old effects into new products with little attention to detail. If you're looking for a good dual reverb unit that does most of your standard effects (although no EQ), the MX400 should work fine. If you're looking for a powerful and creative effects unit that can create some really strange and original sounds, then this is not it.

      Better than I could have hoped for

      Comments about Lexicon MX400 Dual Stereo/Surround Reverb Effects Processor:

      As I have only had it a few weeks, I will give it an 8 overall.
      This is a very cool effects box. I have been slowly upgrading my much older (and I mean 20+ years) equipment in my PA rack. The effects was the last item I had on my list. I had used a DSP 128+ for the whole time and was happy with the performance (mainly because I did not try anything new). Until one time I was able to see this unit set up in for demo. I tried it out and was blown away. I have only had it a few weeks, but am very happy with my purchase as I am still learning of all the various effects and combination of settings I can make. I'm not sure you would need to wait 20+ years like me to upgrade, but when you do upgrade, this is the box that will do the trick.
      Great value. I thought the proce was very reasonable.

      Lexicon-Can't go wrong MX400

      Comments about Lexicon MX400 Dual Stereo/Surround Reverb Effects Processor:

      I bought this unit because I needed some quality delays. The delays can go for a whole 5 seconds with these things. I wanted some quality delay or the ability ro have reverb that stomp boxes just don't do. But when I explored the Flange and chorus I about dropped a load in my pants. If you were to try and buy this if it were around in the 80's it would cost way bigger bucks! It really compares with high end stuff.

      "It's a Lexicon"
      It programs nicely. Easy to adjust and set parameters within a given effect. Im using it for the loop of my guitar head as opposed to people who may be computer plugging with it. There is a footswitch box that one can get to move up or down within channels. And the only thing that it doesn't do is layer more than 2 effects at a time,but I can live with that compared to it's quality and transparency through my signal. I only use a couple of things at a time anyway really.
      Lexicon pretty much wrote the book on studio reverbs. Lexicon,Eventide...I was using the Rocktron Xpression side by side with this Lexicon MX400. I have ordered another MX400 and pulled the Xpression.
      The Lexicon is actually less expensive and I think it is a better machine depending on what your needs are.
      I would say that Lexicon is to the effects world what Marshall or Fender is to the guitar amp world if that makes any sense.
      For all I use it for it's value and ease of function is stellar. For stage live use and for recording studio.
      I use mine for my amps loop in the back. I mainly use ot for it's delays and reverbs-Modulation.
      I love the flanging.

      FANTASTIC

      By jeff deasel

      from germantown, md

      Comments about Lexicon MX400 Dual Stereo/Surround Reverb Effects Processor:

      i have had this unit for a while now, and every time i play, which is pretty much every day, i am just amazed at how good this thing sounds. i know that lexicon products are known for their reverbs, which of course are fantastic, but i have to tell you that this unit has by far the best chorus i have ever heard, period. the chorus is clean, bright, and adjustable in every way, to suit your taste. i've never really been a big fan of the presets on any of the effects that i have, so i don't really use them at all. not to say that the presets on this unit bad in any way, its just my preference. if you are looking for a multi effects processor with fantastic reverbs and the best chorus,"in my opinion" look no further. and for $300, this thing is a steal. just do it, you will be glad you did.

      Lexicon MX 400-Superb Sound

      Comments about Lexicon MX400 Dual Stereo/Surround Reverb Effects Processor:

      I mainly bought this unit for it's digital delays. It has 5 seconds within some of the Digital Delay modes! The Reverbs are also Stellar,but I didn't really buy this unit for the Reverbs or to record on my PC. I bought this unit to loop through my EVH 5150 III. I use a Rocktron Xpression on my other 5150III so on this side I just wanted more Delay abilities since the Rocktron has only about a little more than 1 second of Delay. The Rocktron sounds really nice and clean through my Other 5150III really, But after looping the Lexicon through the other Head and drifting through some of the programs that are in it I was quite amazed. I called up the Flanger and backed off on the Regeneration and the Speed and I even backed off on the Depth. I was floored to say the least. I think this is the most richest fine quality Flanging I have ever felt through a guitar! The first thing I thought of was Alex Leifson. I also have a MXR Blue Face Flanger Doubler from the 70's and it is very useful but this Lexicon Flanger was shocking and transparent and smooth without touching my amps natural distortion. The Chorus was also the same as well. Many people look for a good quality Digital Delay and for what they sell for in stomp box form compared to what this unit is selling for now is just not even in the same league! Don't settle for a lesser brand,Lexicon is a big name in quality. I have a lot to learn in a sense that Im not one of these guys who knows a great deal regarding studio audio gear. I only used the owners manual to identify the IN's and OUT's. I pretty much just started turning through programs and editing on my own. I found it to be very simple. The three edit knobs on the front adjust anything you edit quickly with ease. This thing has 5 seconds of quality delay. Nice sharp crisp delay unlike a mushy stomp box or a different unit that I have experienced. Even though I can only do two effects at a time thats ok because I probably wouldn't do much more than that in most situations. My Rocktron is still a definite keeper and I can layer around 9 or 10 effects at once with that if I want but I will probably never do that. The quality within this Lexicon for what they are selling it for is something to seriously consider even if your looking for one certain effect you will be pleased with the quality. I still have quite a journey within the Lexicon. I like sitting in front of my rack and exploring the programs and seeing what else I will find. I know there are other Models that run for a great deal more $$ but the quality with this MX400 is probably about the best I ever dealt with! Only thing to maybe consider down the road is a MIDI device now for the future to Govern amp channel switching and effect arrangement. Considering the results I have experienced with Modulation's and Delays,now my Pedals are maybe useless except for my Waw and I do like this MXR Phase 90 still in front. Buy It!!!!!!

      Really nice, versatile device

      Comments about Lexicon MX400 Dual Stereo/Surround Reverb Effects Processor:

      This is a killer box and at the price it's being offered at now, it's really hard to buy an MX200 or an MX300.As one would expect from Lexicon, the reverbs are fantastic. From big, boomy caverns, to a little ambiance, everything you're likely to need is here. Even a pretty good spring with a cool 'Boing' parameter to add a little pop. They're eminently tweakable and not over processed like many reverbs I've tried in the past. They'r plenty lush enough, but not so lush that you have to fiddle with it all day and drop the mix to keep it from being too obtrusive.Editing presets via the knobs is certainly doable, but you'll really want to use the pc/mac editor. Not that you can do any more with the editor, but it's a much more convenient interface. The fact that you can use the editor as a VST is a major plus for anyone doing digital recording. Be aware of what this is though. There is no software version of the processing algorithms in this device. It's simply control. No audio passes through the USB cable. Don't discount the usefulness though. With this plug-in you can do things like add automation and save it in your projects. Very handy. The other effects are surprisingly useful as well. The chorus is very sweet and I personally find the detune effect quite useful. I had expected the compressor and de-esser to be afterthoughts, but they're remarkably well done. DBX code according to the specs. Don't worry about noise. As far as I can tell, there is NONE. This is the quietest device I've ever owned. The final thing I want to mention are the ins and outs and this explains why you really should buy this instead of the slightly cheaper MX300. This is a 'Dual Stereo' device. That means that you have two discreet sets of effects running through their own ins and outs. So, essentially, this thing is, electronically speaking, 2 MX300s. My setups is one set of stereo ins and outs running as an external insert to Sonar and the other side in the effects loop of a Fender Cybertwin. Two completely independent, 2 effect chains running at the same time. At this price, you really owe it to yourself to look at this device. World class verbs - and I mean that as well as several other great effects and very versatile routing both internally and externally. If you're in the market, check this thing out!
