Let's Get Technical > Routing & Patching
Mp1 + multieffect + poweramp + pedals
anto84:
Oh thank you rnolan..i'm beginning to understand. What if I add a rack unit for reverb/delay like the Lexicon mpx1 ( which has stereo ins and outs) in a rack with the Ada Mp1, the Spx90 and the peavey classic poweramp? Could you please explain me how to connect everything? I had assumed I could link everything in series ( like ada outs to spx in; from spx out to lexicon in...until poweramp). But as you pointed Spx90 has only one input, while the other gear has two :-\ So If I proceed that way would I lose stereo becaus of the spx90 that accept just one Ada input?
So..is there something different in terms of connection when adding a stereo rack reverb like the Lexicon Mpx1 (or 550) in the procedure you wrote?
And if I will use a mixer I have to run the spx90 and the lexicon separate channels or they are connectec each other in series and only the lexicon outs go to the mixer?
I'm tryng to achieve a rack sound inspired by the ones Dann Huff, Landau had when they used triple chorus like sound
vansinn:
Just a notice.. yes, the SPX90 has mono in (had forgotten about that), but this just means that you'll loose stereo-out from the MP1, which really isn't a big deal, as the MP1 doesn't create much real stereo anyways.
The SPX90 will be the device creating your stereo sound field, so don't worry, especially for the very reason that when you play 'dry' i.e. with no effects, it doesn't really matter if this is mono or stereo.
In other words: MP1 (mono-out) -> (mono-in) SPX90 (stereo-out) -> 5050 (stereo-in)
Not sure it'll pay off using yet another rack device for additional reverb; should you feel like it, maybe just a decent mono reverb pedal in the MP1 send/return loop, set to a nice non-intrusive ambiance.

The 50/50 input jacks are just parallel wired so the sound will combine (mix) at its inputs.

When you say MP1 a/b to 50/50 l/r, do you mean MP1 out A to peavey channel ONE first input and MP1 out B to peavey channel ONE second input ? Or MP1 outA to peavey channel ONE first input and MP1 outB to peavey channel TWO first input?
rnolan:
Hey auto84, so the second, MP1 A > peavey chan1 first input, MP1 B > peavey chan2 first input, SPX L > peavey chan1 2nd input, SPX R > peavey chan2 2nd input. This way you are combining the MP1 outs and the SPX outs using the inputs on the peavey channels. The main reason I suggested this patching is because it preserves the stereo of the SPX and MP1 and all you need to buy is another cab. This would be a good interim set up until you add more gear (e.g. Lexicon)
However, if you want to (can afford) a Lexicon MPX1 then you can chain through it to the poweramp as it's stereo in/out. The reverb in the lexicon will be way better than the SPX90 (which were good in their day). If you went this way, you could use the SPX in the MP1 loop and just use its other FXs (e.g. Delay) One limitation of the cheaper Lexicon mpx units is they only give you 2 FXs at a time as opposed to say a quadverb or Intelliflex or TC GMaj2 etc. which give you 4 FX per patch. Chaining through a stereo FX unit to the power amp (MP1 > Lexicon (or whatever stereo FX) > poweramp) is probably the most common way to patch it.
I disagree with Van about the MP1 in stereo, it makes a big difference particularly to the MP1 chorus (which is where the MP1 goes stereo in its signal chain). Also you can do a great sounding trick buy turning the chorus depth to 100 and the rate to 0, this gives a great fattening very short delay (delay is controlled by the depth setting). Chorus is basically a very short delay (~10 to 40 ms) with the delayed signal modulated (rate) i.e. subtlety pitch shifted up and down. So with rate at 0 no modulation, just short delay >:D :metal: .
I've always used a small mixer and run my rig a bit like you would a PA (both MP1 rig and now MP2 rig). I use a Yamaha AM802 8 ch mixer with 3 FX sends. Everything plugs into 2 channels each. Send 1 and 2 go to my quadverb, and I used to use send 3 to my IPX33 smart shift (in your case you'd use send 3 to go to SPX90. So MP1 (or MP2) chan 1&2, quadverb L/R outs to chan 3&4, IPS33 (or for you SPX90) L/R out to chan 5&6, mixer outs to poweramp L/R. Run FX units full wet (no dry signal) and mix it together with the channel sliders to taste.... You can probably pick up an AM802 2nd hand for not much.
There are always lots of ways to patch things and plenty of posts of the way various members do it. The principles that drive my thoughts are: run it in stereo, try to keep it as analogue as much as you can (and mix in the digital FX etc.), ensure the gain structure is good (much easier with a small desk/mixer).
I suggest your next purchase is another cab, preferably the same as the one you have or buy one that can be run stereo :dunno: . I used a Yamaha 4 x 12 quad box initially and wired it stereo, later I bought 2 ADA 2 x 12 slant split stacks, and I also have a single ADA 2 x 12 slant split stack that I wired to run stereo or mono (less to lug :thumb-up: ).
Chip Roberts:
Hey Anto84, when you say you were experiencing lag with the ME5, did you mean with the MIDI program changes it was lagging? How were you switching patches?
I was thinking of getting one of these units for the analog overdrive and flange, but I have a bunch of units that lag already and I'm not interested in having another one collect dust.
