===> i think the kemper output level may be the devil in the details. i will have to check that against the the SM10 and reach a solution...metering kinda weak on such a device as the sm10. I have just read the Kemper manuals.... really horrible documentation... I can't believe I see such a thingh from a German company. What happened to them? Got so soft! Use the XLR output and have a pretty high output level on it. What are the Lexicons input LEDs showing? ===> averaging on the high side of yellow, ever so slightly red at a rare moment of violent aggression. ===> perhaps i should point the Lexicon trimmers to noon, all switches to +4, and work outward from there? Absolutely! ALL mixer channels MUST be on +4dB. Make sure the Lexicons are on +4dB too... if they have a setting for that in the system parameters. Wet/dry is not an issue... why would that be ? ==> what if i work up a watery mod patch with detune, chorus, echoes, etc, but want to balance the respective levels of each (as i would with each module feeding a mixer in parallel)? If i'm running the box 100% wet on an aux, and i balance effects levels in the box, am i not introducing some "dry" in its path? i suspect i lack a basic understanding of how the PCMs work internally, and need to RTFM. Last but not least... actually FIRST... the SOUND! What you get from PCMs is something you have no idea at the moment. With two of them.... Rumba Mamà!!! ==> sigh....its statements like this that started this thread to begin with. now my eye is twitching and shoulder spasms have begun. Where would i even begin to learn to dial these in? are there some boilerplate patches in the community to use as a starting point? Dial what? Start from hundreds of presets! ==> if you have time, please give me a brief rundown on how i would integrate 1 or 2 PCM8x in such a scenario as mine, in terms of basic routing in and out of box. (mod on one and rvb/dly on other, for example.) connect both inputs and outputs of the 2 PCMs from both miser stereo Aux Sends. RTFM... really well. Tweak tweak tweak. You are just way ahead with words of where you actually are with the PCM architecture knowledge. Makes no sense. I have tried YouTube for some Lex MX400 decent demo... for what YouTube can be... man, I can't believe the horrible tones people post. It a bloodbath. I can't say I know about its sounds... the little I heard is just poor... The software is definitely a scaled down version of the PCM92/96 development and some more "Digitech" stuff... which I'm not that crazy about. But I'd need the box in my hands or a decent audio demo of the unit. Don't really know what to say... but for my working on the Lex effects plugins bundle I have no doubt... it would be an 81 right away. It just sounds nicer. I have an 80 and an 81 and together they can do some amazing stuff. Probably "less things" than 2 MX400s at the same time... but what's the point? Quantity? People buy Zoom for that. Me? Nope. Tone is priority! Converters. But... to tell you the truth... when you have 10 delays, some modulated, some glided and a reverb in an algorithm... I don't see much missing there... add another PCM for other stuff... done.
