Maybe you should make it lauder.
There is a weird noise in this.

What I use:
Ubuntu Xfce 4.12
LMMS 1.1.3
Instruments plugin: VeSTige: DSK Overture: Orchestra Drum Kit


What is it and how should I fix this?

There is a weird noise in this.

DSK has sometimes worked in disappointing ways in lmms
I am not sure...
..But i think that artefact actually is inside the actual sample!
But even if that is so, lmms can aid you to get rid of it.
First you need to learn about envelopes
https://lmms.io/wiki/index.php?title=In ... .2FLFO_tab

The trick is to find a setting of attack (ATK) and release (REL) that will keep the sound, but omit the artefact!

Thank you for the answer. I am trying to fix this with the envelopes, but it will be worse.
Anyway, it is okay that if I set for example the attack of the sound, and it would be lesser noise, but I need the original attack.
So I set the envelopes because of the sound not because of avoid of the noise. Right?

But actually I can set is however the noise is stays,

For example there is noise where the drum starts and where ends:

I have no idea why is that and what I should do.

[musikbear]

what I should do.

imo use a different sound. Try the files in the Drum section in the samples, and use the Audiofileprosessor (AFP), you have full control of the sample, that way.

Two (rather annoying) solutions:

1) Add an Amplifier to the Plugin tab of the instrument, and make an automation of the volume of this Amplifier, i.e. place the volume at 0 at the places where the unwanted click appears.

2) Or edit the sound in which this unwanted click appears using editing software such as Audacity. And then import it into LMMS as a sample.

I setted the release and the amt, which I am not sure what, but it helped.

Thank you for the advices.

Thank you for the advices.

The volume envelope is used to define how the amplitude of the sound of an instrument behaves when a note is played.

When the envelope is inactive (amount or AMT = 0) and a note is played, the amplitude reaches its maximum instantly, and will remain at that level until the note is released. Once the note is released, the amplitude returns to 0 instantly.

When the envelope is active (amount or AMT = 1) and a note is played, the amplitude of the sound:
- will remain a certain time at 0 (delay or DEL),
- will take some time to go from 0 to its maximum level (attack or ATT),
- will remain for some time at its maximum level (hold or HOLD),
- will take some time to decline to the sustain level (decay or DEC),
- will remain at the sustain level until the note is released (sustain or SUST),
- will take some time to go from the sustain level to 0 once the note is released (release or REL).

The release (REL) is a time parameter:
With REL = 0, the sound stops instantly when the note is released.
With REL > 0, the sound takes longer to turn off.

When AMT is between 0 and 1, the result is a mixture between AMT = 0 and AMT = 1.

With AMT = 1, to mimic AMT = 0:
- DEL = 0
- ATT = 0
- HOLD = 0
- DEC = 0
- SUST = 1
- REL = 0

If it can help

EDIT:
- level 0 corresponds to silence
- the maximum level corresponds to the instrument's VOL (knob to the left of PAN)

Thank you for the details! It will be useful.

How old is your computer?

[Ayala]

Quite new.
I have bought it a year ago. Asus X550V.
