Genos Digital recording glitch noise

[Burtoiu Florin]

Hi , i have in my setul an Antelope Zen Q Synergy Core sound card that has a digital input , and wheen i am recording my Genos with the digital cable ( Cordial CPDS cable ) i hear some noise at 16k - 18 k. Did some one notice this sound ? I will atach audio fils , you can hear it at the end of pattern.

Hi Burtoiu and welcome aboard.

I didn't hear much of a distortion but it wouldn't surprise me if there is some anomaly in the sample itself on the Genos. I have a few notes in mainly the piano voices that have a buzz in them. Over the years, I have heard these noises on various electronic Yamaha pianos I've owned.

Why would you not simply use the keyboard's WAV recorder? That should be the best recorded sound you can get.

[Lee Batchelor]

Very true Drake but if the sample is flawed, the recording will be too. I don't understand why we pay $7,000 for a keyboard that has the odd buzzing sounds in the samples. There aren't many and in a performance environment, they are never heard but in playback through top of the line speakers, they stand out  .

To be fair, many instruments and even VST instruments suffer from noise in a few samples (sometimes more). My Roland organ was top of the line, £25K list price, and that has some noise on some notes in some instruments.

Makers work very hard at de-noising samples (I personally know some of the people who do this at Yamaha and have talked to them about it) but it's often very difficult or impossible to remove noise from a sample which has the noise from the actual recorded instrument.

I have a set of VST strings that retailed at over £1000, and even that has some digital noise in the higher notes.

Nothing will ever be perfect. I wish it could be!

[Lee Batchelor]

Fully agreed, Andy. There's no such thing as the perfect sample...other than the real thing . It's just that some samples are far better than others.

We haven't heard back from Burtoiu. I wonder if the he's found another cause of the distortion?

True that! I sampled a few of the Yamaha Genos electric piano voices last week. (A whole separate crazy project.) The job forced me to listen carefully and critically to the original sounds (samples). Stuff gets through, especially from those old mechanical electric pianos. Part of the "charm"!

If you wait a few years, you won't be able to hear frequencies above 16K and you will no longer hear a problem. That should start to occur when you reach 40.

At my age, I cannot hear anything over 10K, but that is normal.

It might well be that the sound designers working on the samples might be over 40 and could not hear the high frequency noise. Of course, a good oscilloscope would show it.

Burtoiu,

I hear distortion in the middle of the G1 file (from clipping) but if the issue was at the end of the file, I'm afraid my PC speakers aren't good enough to hear any issues. If the issue you're referring to is the sound/clipping, the signal is too hot; you may need to adjust the volume of the voices/styles, or the digital output volume (Utility -> SPeaker Connectivity). I'm not sure if you already know this, but the digital out on Genos is *not* designed for RCA. it's designed for Spdif coaxial cable, which appears like a normal RCA cable, but they're not the same (SPDIF is stereo, for one)

[Lee Batchelor]

Agreed, Mark. I was going to suggest that next - an overloaded signal source.

Pity the OP hasn't replied.
