KORE Deep Reconstruction effect crackling

Forum,

Some effects from the Deep Reconstruction package generate crackling when I morph through the A-H fields. Here is the rather simple procedure: I load in a DAW track a VST synth (any synth) and play. Works fine. Then I choose a KORE 2 Player FX in this track to manipulate the audio. A very simple setup indeed. I choose for instance an effect called The Magic Number from DR. KORE 2 users know that the most profound effects are generated by morphing the A-H fields. By morphing this particular effect, digital distortion is heard. Also, the Amp Mode dial for this effect has the same result, as do some echo and delay adjustments. I estimate that a mere 5% of the Deep Reconstruction effects show this behaviour.

Question: Is this an unsurmountable limitation due to the already complex basic sound from the used synth shuttling through the complex filterings of the Deep Reconstruction routines? Or is this an audio interface artefact that can be solved? Or, thirdly, is this something I don't know and you can tell me?

Are there any KORE 2 Player FX users experiencing the same 'problem'? Perhaps you can try this effect yourself.

Thanks for replying.

My system is much older than yours and less powerful, but I don't get the crackling you noticed.

I put one instance of Kore in a track and ran a dry synth in that track using about 15% CPU.

Then I added Kore FX VST after that in the same track (so it uses the same CPU core) and loaded the Deep Recon preset you mention.

The CPU went up a few percent.

Morphing a-> h sounds normal to me. No digital crackling or dropouts and the CPU does not exceed about 30%.

There are, of course, the zipper-type sweeps when the delay line lengths are changed - that's the nature of the effect and it sounds cool if you do it slowly - but that's not the noise you refer.

Perhaps your VST audio buffer size is too small?

Live uses one core per track, I don't know how Sonar does it, but you could try moving the effect to a send which might use a different cpu core to see if that makes a difference.

Since this is your first post - Welcome!

 

Welcome =)

I'm not seeing this either in Live, Sonar or with Kore as a standalone. Upping your buffers is a good suggestion.

Thanks Jim, ew,

My CPU potential is OK, that's not an issue. I use my my Audio Kontrol 1 interface with ASIO, obviously, and have tried several latency settings. From the highest to the lowest latency. This has no effect on the noisy crackling though. The zipper-type sweeps are of course present in the more heavier effects, but this is normal, and is fun from a creative point of view. Note also that some effects do not work anyway (approx. 5% of the 150 effects). Nevertheless, my thoughts are pointing towards the Audio Kontrol 1. You both do not use this interface in your set-up?

Another thing involves stand alone. I've tried Kore 2 Player (or any available soft synth) in stand alone mode, in instrument mode, and played a sound through the MIDI controller Then I opened another stand alone instance of Kore 2 Player, in FX mode. Unfortunately, the FX instance does not work at all on the created sound. (I tried this because I wanted to check whether SONAR is the source of the crackling in e.g. the The Magic Number effect.) Audio and MIDI routing settings seems OK. This also made me wondering if something is wrong with the AK1, of which I have the latest drivers installed.

Any thoughts?

It's not going to- there's no routing between the two standalone apps.

I don't have that interface.

I went through most of the Deep Recon presets and didn't notice any problems.
