the mpc2500 would record samples in mono or stereo but while monitoring the recorded sound in mono it would send the mono to both left and right ouputs. The ren doesnt do this.... no matter what mode (stereo, left or right) ... am i doing something wrong? im recording some guitar into the left input and i have the mode set to "left" instead of stereo and i get output only to the left .. with this mono mode setting shouldnt i be hearing from both left and right outputs?

yea..that makes sense lol.. the mpc2500 gave it a direction itself because you didn't. vaguely, one can say that mono is pointless if it isn't given a direction.

you have to give it a direction, either to the left or right.. or else it will split itself (such as mics & guitars) and not stay as mono.

Think of it as a block of jello.

ONE block of huge jello is a MONO. Underneath a jello, there is a piece of paper with a line dead center down the middle. that line represents the digital processing before the sound leaves for your headphones. The line is there, but the jello is still MONO (ONE PIECE, together).

a. Now, if you slide the jello to the LEFT, it will all stay LEFT of that line (you will perceive it to be to the left). - what you are doing with your MPC RENN.
b. If you leave the jello AS IS, it will stay 50% left, 50% right (you didn't give it a direction.. So you perceive it to be "stereo").. but it's still kept together!! (still MONO). - what the MPC2500 did.

If you cut the jello following the straight line, now you have physically separated the mono signal left and right.. this represents a y-split cable, or output to your left & right speakers, or output to your headphones. mono -> (LEFT & RIGHT) split

Image

it's so easy that it's so complicating..

MONO is short lived. It's bound to become stereo. The only life span it has is while it's being input'd into a recording. After that, it gets shredded up. Unless you tell it to stick to the left or right. Recording (done through inputs) are all done in MONO signal. I think it's because it's just better quality, and having 2 Left & Right inputs for recording is just impractical. Imagine if you had a drum set and 3 band singers.. a Drum Set would have about 15 microphone connections & each singer would have 1. 15x2 = 30 wires!!! :0...

So let's just keep the quantity of wires half...
I think quality of the recording also has alot to do with it.. but i don't get into that stuff. people's ears can't even tell.

look at your index finger and following it as you move it closer to your nose.

you are now cross eyed..and that finger tip represents mono. even if it's mono mode, if you record to the left, it will still stick to the left. because even if your fingers are at the middle, you still can see with your left and right eye.

what you did with the renn is this:
1. get cross-eyed again with the finger close to your nose
2. close your right eye.
that is what's happening. it's still mono mode, but you see it with your left. the direction you will perceive it from is the left.

do you want another analogy?

why are you recording the guitar to the left anyways?

whoa....thanks for all of that. what im saying is that even changing the "mode" (stereo, left, right) on the mpc ren... i get the same result no matter what.

There is no difference between the left, right, and stereo mode for me as well. I wanted to monitor individual sides to see if what I was listening to was worth sampling. Am I doing anything wrong or is this a glitche?

Does it do the same with the Direct Mon knob turned all the way to Computer?

I don't have one to test with, but you would think it 'should' work the same as the MPC2500, when set to mono, it 'should' output the mono signal in the centre of the stereo outputs.

Open it in an audio editor and check it out.

If both left and right show up and they are the exact same looking waveform then it's most likely a mono sample placed on both sides, still sounds mono.

If only one big waveform shows up it's mono.

If both sides show up and they look a bit different and sound different in the headphones/monitors it's stereo or has stereo processing (giving it movement across the sides, sample can be mono or stereo for this to happen).

You have to check it for yourself, only you can figure out what you wanna deal with.

I think it is more to do with monitoring the input signal in sample record mode, while only having a mono input, rather than the recorded sample?

Pisses me off, too. I'd love to have mono stuff coming from the middle.

Most recording gear, the Left input is mono and usually suited to record mics and guitar. All older MPCs record mono thru the left input.

Capeesh.

No, it doesn't do it like the mpc2500.

I haven't found a way to do it with a condenser mic plugged in to the Ren.

There is a way to do it with a build in Mic of the comp.

"input 1+2" thats stereo I can see that coming in as stereo with audio recorded on one channel, Im not on the mpc right now so i'll have to check later. Can you select a single (mono) input under the mpc preferences from whatever audio interface you're using?

No, you can't.
