Can you give a try with 1.1? And the 1.1 is much better than 1.0.7 by the way

Ace is running fine in bitwig 1.1

Only not that friendly for my old laptop from 2008

.
But good enough to try

Kickass! Never expected this!

GAMECHANGER!

U-He vst for Linux - the reason to manage it spontaneous and installed Ubuntu 14.04 with some KXStudio metas on my older mid 2010 ( iMac 27' i7/16GB Ram) and make some tests with Bitwig 1.1 and Renoise 3.1. I had some probs with my fw audio hardware (Saffire Pro24 DSP), but beside this and with USB-audio (THR5) everything working fine!

I had no deep view now , my first imprint is, the overall performance is not so smooth as with OSX when using the same (host) software - but it is great to have this opportunity and its working much better then I expected. The multicore switch in Diva is more important as in OSX, it makes a really difference (crackles without) I've mainly tested Diva and Podolski. I will report If i find serious bugs.

Thx to Sascha, Clemens and Urs.

Hi Lump,
If you were able to evaluate the slowdown compared to Mac, what would it be?
Thanks.

Thanks.

The overall performance of the audio subsystem - it never "feels" rock stable and fast like on the mac. There are a lot of clicks and pops eg when I turn midi controller (cc) - xruns - in jackd, even with a higher buffer (256 f/p/s) . I was able to record this clicks and pops by capturing the audiostream. With OSX on e same computer, I use a lot of Diva instances with 64 f/p/s without any click.

I've made a lot of tweaks: Installed the recent low-latency kernel, add user to group audio, rtprio for usb or firewire -it helps a bit, but at least I'm not satisfied at this point. On the other side I'm surprised how many hardware is supported "ootb" - Push (in Bitwig), Saffire (now with softwarecontrol), THR5 (Yamaha modeling amp) and the complete iMac hardware.

Can you tell me your cpu model? (cat /proc/cpuinfo).
For me it is rocking stable.

I have this in /etc/security/limits.conf:

Code: Select all

@audio          -       rtprio          unlimited
@audio          -       nice            unlimited
@audio          -       memlock         unlimited
@audio          -       priority        unlimited
@audio          -       cpu             unlimited

Please make sure that you're in the audio group (you can check that with the command "id").

And I don't use jack, just plain ALSA.

Thats the point - I made the same experience; with pure ALSA it working much better then with JACK.

I will make some tests later and report!

nevertheless thx for help.

Yes your CPU is better than mine:

processor	: 0
vendor_id	: GenuineIntel
cpu family	: 6
model		: 30

microcode	: 0x7

So it is mainly some configuration issues

It appears that your CPU cores are throttled, at least in this report.

I think it is just dynamic clock, so when you're idle you don't consume too much power.

Hi Dave

This is not the latest hardware (2010) but still a very fast and beautiful computer. I think if there is something throttled, it must be a feature, that "maybe" the recent linux kernel can't handle properly. But I haven't tested abiques tips for PAM (unlimited) yet because my children don't let me a minute in my studio this WE

So on monday morning, the quiet hour for daddy.... thank you Dave

BTW: I've ordered an Arturia Bundle with Keylab 25 and a license of Bitwig Studio - seemed to be a good value for the money (322 €) what you think?

abique · Post by **abique** » Sun Nov 23, 2014 10:17 am

It is not for PAM, but for /etc/security/limits.conf ^^.
Arturia Bundle is fantastic, you'll enjoy it.

Insist on a completely perfect keyboard, there have been issues at Arturia:

You may have a cpu governor at work. As root user check for this information:

Code: Select all

# cpupower frequency-info
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  hardware limits: 500 MHz - 2.00 GHz
  available frequency steps: 2.00 GHz, 1000 MHz, 500 MHz
  available cpufreq governors: conservative, userspace, powersave, ondemand, performance
  current policy: frequency should be within 500 MHz and 2.00 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 500 MHz (asserted by call to hardware).
  boost state support:
    Supported: no
    Active: no
    Boost States: 0
    Total States: 3
    Pstate-P0:  2000MHz
    Pstate-P1:  1000MHz
    Pstate-P2:  500MHz

Run the command before and during a session to check if a governor has kicked in.

You can then use the cpupower utility to set the min/max for the governor, or you can set the governor to performance, though of course that's going to run your CPU at full speed all the time, so keep the cooler handy.

Hopefully there are no issues with cpupower and recent kernels.

Best,

dp
