Hissy delay's in Piano sounds

Night Spirit · Post by **Night Spirit** » Wed Nov 30, 2011 8:45 pm

Hello was wondering if anyone has experienced this in the Piano engines. When I use the damper and let cords ring out, they have a very hissy back round noise. It lasts the entire time I keep the damper down and won't go away till I release the damper. I have the damper noise off since I don't like it, and the key noise off as well since I don't care for that back round noise. But that hissy noise that stays on and is very audible after I play a few cords holding down the damper is reallly irritating. Anyone experience this or know how I can get rid of it, it is messing up my recordings and not allowing me to let accent notes ring out.

No, absolutely not. I hear no hiss at all. Are you sure you do not have a volume/level problem, and that you are not using an effect, such as a compressor, which could cause this?

Yeah I noticed just the same thing a while ago. You'll hear it when you sustain a lot of notes and let them ring out. Didn't really bother me at the time, but I'm interested in the technical reason why this happens.

Can you record the sound? I'd like to hear it.

yes I can record it when I get home and host a file, at work currently so can not. I am using no effects its the standard German Grand on the programs 000 done no tweaks what so ever, other then stopping the damper and key strike noise. But I did forget to mention it happens when you sustain a few notes at a time. Just try doing a couple triads all sustained and let them ring, you will hear what I am talking about immediately. What is the volume/level problem you are talking about?

Sounds to me like this might be the damper resonance: the soundboard & all strings resonating together. That's the sound of the piano.

sorry was unable to make a file of it last night, as did not get home till 3:30am, but it's definatly not the damper resonance. I was tweaking those to try and stop it. It is a long hissing like a static ground hum. It is defiantly not a sound that is trying to make it seam more realistic, it is a nasty hissing. Just go to your german grand hold the damper down and just start pounding away on notes then let it ring you will hear what I am talking about.

I tried this last night. I am not able to reproduce it.

I have just done so again, and hear only the damper resonance. I'll try to post a recording later today.

Here are a few quick recordings of A000 German Grand, using major 7th chords in mid and high ranges with and without the damper resonance. The resonance is particularly noticeable as a separate element on the high notes, since the resonances of the soundboard and lower strings are much lower than the main note's fundamental frequency. As you play lower, or play bass notes, the resonances blend into the timbre. Are you getting a different result on your system, or is this what you were referring to?

Sorry for my major lack of support on my question, I promised audio filed and have failed to deliver. Ended up stuck late at work, and when finally got home just passed out due to major lack of sleep. I promise tonight, I will get the audio files up.

DanatKorg I thank you for your help in this matter it is much appreciated. Now how ever you are playing single cords, which will not cause the hissing sound. Start on Middle c and just play cords, triads heck even just mash a bunch of keys, keep doing that till you have played around 5 cords, or triads or mashed down 5 different areas of the keyboard all while the damper/sustain is on. Once you do that which is the important key you must play multiple notes you will get the sound I am talking about.

I will make a audio file when I get home so you can hear what I am talking about, but for anyone who is reading this post, just start smashing away on keys keeping the damper down the entire time. Make it sound nasty and loud then let them ring out, and you will hear what I am talking about immediately as that hissing starts immediately.

Night Spirit, I have done exactly as you suggested, even going so far as to play and mash every note on the keyboard, and I am unable to produce any hiss whatsoever. It really sounds like you have something wrong with your board.

Is this on all programs or only on a few?

If it's a heavily compressed piano sound, the compression could bring background noise out (notably, it would do this if it were a real recording too)

This sounds more like a problem with the OP's cabling/amplification than the Kronos itself. If you are going through a mixer, and have the pre-gain or master gain thrown up high (either because you have the Kronos level down, or your amp isn't turned up enough) then you'll be amplifying the noise floor which will be a sum total of all the noise in every element of the chain from the Kronos itself, anything picked up by the cables, the mixer (if any) and the circuitry of the amp.

If you turn your Kronos up, and your amp/mixer down, does the hiss reduce noticeably?

Also, check with headphones on. If the hiss isn't present in the headphones then this is almost certainly something wrong with your amplification.

It's ironic that this thread popped up this week because I noticed on Thursday when I was playing at church (just a practice session) that there was a marked hissing noted with all of my piano sounds. I have never experienced this before and never in my home setup. I didn't try to completely debug this issue as we didn't have our usual sound guys around, but I'm quite sure it was that the main mixer in the room was set differently than usual, most probably a compressor was set in the input I was using.

I add this only to say that I too am suspicious that the OP may have something in the amplification side of the setup that is causing this problem. (At least if his problem was at all what I was experiencing this week.)
