I play trough my focusrite forte, the line outs of my keyboard are connected with the line in’s of my focusriteforte, and so on the line out’s of my focusrite are connected with my speakers. But I don’t think my focusrite or the setup could be a problem?
I directly record to audacity, I don’t record as midi-file. My keyboard is a KORG m50 Music workstation.
Well, Audacity is not the problem, because it does not apply live effects or modifications to the audio input you give it.
What do Focusrite say about the problem Contact Us | Focusrite?

Okay I’ll do it.
thanks
I’ve just listened to your “blocky” sample, and it sounds OK to me. 
The piano is playing more gently than in the “not blocky” sample, but both play fine and have a nice piano tone.
I did my best at the two samples and used the sustain pedal correctly. There is still sustain also at the “blocky” sample but it more sounds like the sustain of a toy piano
Does anyone else hear anything wrong with either of these piano samples?

Really my ears are old now, but even to me, the blocky one is far worse, I would call it “muddy and congealed”.
And comparing the almost identical phrase in each sample, look how much of the highest (audible) frequencies are missing in the blocky one.
Why this is happening, I don’t know, but given frequencies are an issue, sample rates were my best guess.

To me, the “problem” one does sound more “muted”, but like a piano being played more quietly (but recorded at about the same level as the other clip)
In this sample, I have taken the common phrase from each clip, lowered the level of the “bad” clip a little, and merged to two into one track. To me it just sounds like a phrase repeated quietly.
I don’t understand what “blocky” means in relation to these audio clips. I don’t hear anything that sounds “blocky” (whatever that means).
I asked focusrite and they recommend to try another DAW and look if the problem still occurs.
The volume reduction makes the congealed sound in the “bad” clip less evident I agree, but the difference is still there for me.
I’m using cheapskate speakers worth about £100 if bought now. You?
Gale
Both floor-standing British made (JPW) floor standing speakers (about £250 if bought now) and cheap but pretty decent monitor headphones.
“Blocky” implies to me “blocks” - what does that mean?
“Muted” I would understand, but “blocky” makes me think that it could be a playback “stutter” problem.
Wow - same manufacturer as mine, but I have “Mini” speakers.
I don’t read it like that, but let’s try that.
@Merlino, restart Audacity.
Make sure project rate bottom left is 48000 Hz.
Generate > Click Track.
Effect > Amplify…, choose New Peak Amplitude -8.00 dB.
Drag in your good track.
Play. Does the piano sound stutter or deteriorate?
Gale
I would be very surprised if it didn’t occur in another app, but let us know.
Gale
What a coincidence. I got the big ones - they were a really good deal from Richer Sounds many years ago. I replaced the tweeters (new ones from JPW) a few years ago because one of them was starting to sizzle a little. I was pleasantly surprised by how helpful the guys at JPW were.
Thanks for all the troubleshooting guys. I’ll try everything above and let you guys know asap!
Sorry let me try to explain blocky: the gentle tones are a littlebit cutted like it sounds more like a xylophone with piano sounds
And I think that is due to the loss of higher frequencies in the “blocky” recording.
But can you try the test at more tracks = sustain/sound problem? - #33 by Gale_Andrews anyway, using Focusrite for playback device, then again using your built-in sound card? It could be that there is playback deterioration as well when there is more than one track, which might be making the problem worse than we hear it (though I can hear what you mean).
Gale
Merlino, please try downloading this short WAV file.

Import it into an empty Audacity project and play it.
It is the same phrase played twice - the second time is played more quietly.
Please describe how it sounds to you.
the second part sounds a littlebit more quietly indeed. Thats what I hear.
Thankyou for all the work you put in there!
