Help: How to remove FXs from the Audio Input signal

metallo · Post by **metallo** » Thu May 02, 2013 10:43 am

i already have open in the past a similar but differen thread related to this (http://www.korgforums.com/forum/phpBB2/ ... highlight=)

Basically this is a problem I still haven't fixed...how to remove the FXs from the audio input signal to record a audio track into the sequencer.

When I plug in my V-Synth into any of the Audio input on the kronos the signal is processed by the Total or Master Effects (In Global Mode I assign the signal to L/R and Audio Output LR bus, Inv assign to OFF, but the signal is still effected by the TFXs).

Now, this is not a problem if i just want to play live, i assign the signal to the output 3 and 4 and I solve.

The problem is when I want to record an Audio track in the sequencer.

I did a couple of experiments:

1) i plugged the V-Synth into the Kronos and tried to record into the sequecer, with all the IFXs, TFXs and MFXs off......the sound is different, there is some sort of effect applied but can't figure out where.

2) I recorded a Wav file with the sound of the V-Synth and imported into the sequencer and it sounds correctly, as it comes from the V-Synth....no effects applied.

Can you help me to understand why it happens? currently it is impossible to me to use the audio sequencer wih direct plug....it annoying honestly.

All your help is much appreciated

Any suggestion?

Are you perhaps not panning the tracks correctly? You could get phase cancellation if you record to two tracks and leave them both panned center.

I'm recording mono, so just one track.
The problem is that even just plugging the V-Synth BEFORE starting to record, the sound is effected.

Looks like there is an effect applied at the beginning of the chain, on the input signal, and not at the end on the output.

Does disabling Global IFX/MFX/TFX do anything?

And you're sure there is no input clipping? If you go to the audio tab and play your VSynth, it doesn't flash "ADC overload"?

The TFX will be applied to any output from L/R. The effect is not recorded on to the audio track though. You hear the effect, because the audio track is played through TFX as well.

You can route the recorded audio track to Audio outs 3/4 and listen to the tracks there, you will see they are not affected by TFX.

Or, you can disable the TFX, and see that the recorded audio was not with TFX, provided you didn't have any other effects enabled on the Audio input.

Nothing unfortunately.

Yes, no clipping at all.

As written in the first post, I disabled everything, all the effects, but the sound coming from the V-Synth is still effected.

the only thing i can think of is that you don't sent a mono signal from the vsynth to the kronos, so you will get a different result in that case then you hear from the vsynth.

did you try to record the vsynth in stereo (on two audio tracks panned left and right) and is in still wrong in that case?

I've never experienced something strange during the recording of a mono or stereo signal. That makes me wonder, how do you create the mono signal from the vsynth? (do you just record the left channel (and missing the righ channel), or do you sum both channels to a mono channel before recording it in the kronos?)

i'm using the left channel from the V-Synth into the input 1 of the kronos, using a mono cable.

The only thing i didn't try is to change the cable or to record stereo on 2 different channels panned L and R.

Would it be possible for you to upload an example (or two then, I guess) thar demontrates the difference?

Can you monitoring VSynth in mono, directly from VSynth, without going into KRONOS?

The Roland V-Synth manual strongly suggests using the V-synth in stereo. When using only one output, they say to use the L/Mono output. This implies to me that the system detects when no cable is plugged into the right output, and in that case sends a mono summation to the L/Mono output. This mono summation will generally sound different from the stereo output; just how different depends on the specific audio content. In some cases, it may sound radically different.

Because of this, I think it's best to record the V-Synth in stereo. Try it and see.

As a side point, make sure that the Mic/Line switches on the back of the Kronos are set appropriately, and that the input level knobs are set optimally.

Hope this helps,

Dan
