Hi, I am not a linux guru who would be able to help you out with exact commands and so on. But here are some general ideas. 1st : On my Lenovo Ideapad l380 the touchpad works with advanced features only inside the desktop-environment (in my case: KDE). If I use pure X instead, I only get mouse movem...

@khz : For cloud + internet, realtime is nonsense. Here you want a task scheduler such that everyone gets his share of system power. If you have 500 users instead of 50 on a busy day, the system will still work, but slower. With a realtime kernel, the one with the highest priority would get his pack...

the vnc would be for manupilation of the gui, only (modify a volume slider, for instance). Of course not for sound! I have so far only done the following: - use a cheap notebook + usb interface for pianoteq. This worked, but only with no network + cpu governor performance + no desktop environment (I...

Hi, this is not my kind of music, but as you have not yet gotten any answers: I think there is some lack in the lower end. I have listened to some other electronic tracks for a comparison. But my speakers go only down to 50 Hz, so if your lower end is significantly lower than that I might have overh...

Could you point out in which situations exactly you did get xruns with a non-realtime kernel? I had used a 64 bit buffer, and I had no xruns during that gig except when loading / saving files, not while playing. As I said, using network for remote-acces via vnc would be interesting for me, would, fo...

I had a small gig this evening, and we used the setup I discussed here for our mix. Nuri, this might be interesting for you: Instead of small adjustments (which I had expected) rather big adjustments were necessary, because we used a different P.A. than for our rehearsals. This one had much more pow...

I repeat my question: Do you use the scarlett interface again? Did you reconfigure jack to use the scarlett interface?

Ok, I found a solution / a workaround / maybe an explanation. I did not succeed in trying this with ardour. That's probably why I was using qtractor in the first place: I instantly got along with it, while I do not get the basics of ardour (I am a long-time cubase user, have started this on the Atar...

I've always loved my Crate amps. Probably you should just spend some time at a guitar store playing on different amps and see what your ear likes. This is a job for experiential learning, I think. Hey, I had (and still have) a Crate amp, too! Though I don't use it anymore, my ears don't stand a lou...

Short update: For this evenings rehearsal, I used 48 kHz, 64 bit buffer, 3 periods (jack showed 4 ms latency). I switched off hyperthreading and used icewm instead of kde (which is my normal desktop). I used 6 channels out of 8, pianoteq, compressor + eq + cabinet simulation for the bass, reverb + l...

Interesting. At first I thought this must be nonsense (switching off hyperthreading), but I did some research. You are right, it is generally recommended to turn it off for realtime applications (at least on linux). See here: http://linuxrealtime.org/index.php/Hardware_Aspects#Hyper-Threading The re...

So you use the scarlett again?

Then you must use that as jack-device, for input and output (you could use both sound card, but this is an advanced topic and won't give optimal results).

Select your Scarlett as Audio hardware in cadence, then you should get things working.

In my case it was just easier using one virtual instrument and go for extreme low latency to detect problems (in this case, as you said, there were background processes, but not network, which was off) than testing this at the rehearsal. For me when playing piano or guitar, everything up to 128 samp...

I have done some more experiments with pianoteq alone. I started with my normal kde session. If I go at 64 samples (3 periods) at 96 kHz or 32 samples at 48 kHz, I get the occasional dropout. (every minute or so) Then I started an ICE-WM session as an alternative. Here I have no dropouts at this lat...
