New Ubuntu User

Yes, i am very sorry - but my windows crashed! bla bla - long story!

I have linux ubuntu! yaaaah ! and my computer is running again! YES SIR!

But how on earth do i install Renoise.
I thought it was “dobbelt-click” and install…
But i have no idea what to do, after reading :
http://www.neurotix.com/music/renoise_for_linux_howto.html
It makes no sence to me…

I am rly sorry, but can some one guide me?

Renoise Single User Installation

This procedure will install Renoise for Linux in a directory under the user home. At the end of this procedure you’ll get a Single User Installation of Renoise.First of all download Renoise in a directory where you have read/write access (your home directory “~” should be a good place - the example below assumes that you save the archive in your home directory). When you have the Renoise archive open a terminal and type the following commands:

$ cd
[enter]
$ tar xvf rns_x_y_z_reg.tar.gz
[enter]

Once the decompression ended the rns_x_y_z directory has been created. Let’s go in it:

$ cd rns_x_y_z_reg
[enter]

We are ready to try running Renoise:

$ ./renoise
[enter]

Now the Renoise splash screen should pop up while the terminal is filled of log messages (nothing bad, it is all correct). If this is not what happened see the troubleshooting section.

Awesome! So far so good!! ( i tried it before, but that wouldnt work - but i does now?! )
BUT! :)

[i]Failed to create a RealTime priority thread for ALSA. Will create a non RT thread instead…

It is highly recommended to use RealTime priority audio threads with ALSA AND Jack to get acceptable audio latencies, but you may need admin rights to create RT threads. Please see the Renoise for Linux FAQ on http://tutorials.renoise.com for more details.[/i]

I have installed jackd now…
and now i dont know what to do

Realtime Threads

Ho do I configure Linux to enable Realtime Threads for ALSA or JACK?

To allow Renoise to create realtime threads, which are required for low latencies with ALSA or JACK, you have to edit the /etc/security/limits.conf file. A realtime kernel does NOT help here, does not set the required options automatically! To enable RT thread creation via PAM open the /etc/security/limits.conf file as root (or via sudo). Then somewhere at the end of the file add:

YOURUSERNAME - rtprio 99
YOURUSERNAME - nice −10

Alternatively you could also create a group “Audio”, add your user to that group, and use “@Audio” instead of “YOURUSERNAME”.Save. Log Out. Login. Then it should work. To make sure that it works, launch Renoise, select ALSA and make sure the “Realtime threads” option is on. You will get a friendly warning if RT creation failed.You can find a more detailed explanation about PAM and low latencies in Linux here http://tapas.affenbande.org/wordpress/?page_id=73.

You don’t have to use Jack for realtime threads. When you edited the limits.conf file you can use ALSA with realtime priority.

I have no idea what to do, or what you are wríting. Sorry, i aint trying to be rude.
And the link dosent work.
Where do i find " /etc/security/limits.conf "

I can enter Renoise, and listen to music now…
I just have to unmark the "use realtime pri----- because i have no clue, how to set that up…

But where do i install plugs for Renoise in Ubuntu… And if i install windows plugs with wine, where n how do i find the folder? Or how do i find the directory for the native linux renoise plugs…
I rly have no clue. Please help :)

Open a text editor, for example gedit on ubuntu and open the file limits.conf in the /etc/security folder. Add these two lines at the buttom of the file:

YOURUSERNAME - rtprio 99
YOURUSERNAME - nice −10

replace YOURUSERNAME with your own name.

Log out and log in. Now you should be able to use the realtime checkbox in the audio pane in the preferences.

i dont have access to change that,.
Should i try to install Jack?

for all access, use “sudo” before anything that you start and you shouldn’t have any problems changing config files.

Thank you. But the thing is, that i dont know how to get there by the terminal. I am super new to Ubuntu- and all this rly doenst make any sense to me. I have unpacked Renoise in a homefolder called Renoise. I can open Renoise in the unpacked folder, but i get the error everytime.

Now…I know how to get to limits.conf in the /etc/security folder. But not by the terminal…
How do i do that?

I am rly trying to learn, and just got to know Renoise in Windows. But i hate windows n vira and plugins n updates n virusscanners etc–
so i changed to linux. Ubuntu. And i am rly trying to learn it- sorry, but please hang on:)

in the terminal you could simply try “sudo gedit” and then use gedit to browse to the folder.
As long as you start gedit on a priviledged level, you can edit files and save them as well.
I don’t know the new ubuntu release, but perhaps there is a context menu that allows you to start a program with sudo when you right click on it.

In a terminal window, type the following:

  
sudo gedit /etc/security/limits.conf  
  

It will prompt you for your password, which you need to enter, and then it will launch the editor with the correct file. Make the changes described above in the thread, then save the file. I think you will also need to log out and log back in again for the changes to take effect.

After I type the first two commands it just shows this message

tar: rns_x_y_z_reg.tar.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now

What should I do?

Are you sure that you’ve typed the version number, i.e. “rns_2_8_0_reg.tar.gz” ??

I’ve found this script helpful in enacting realtime support:
http://code.google.com/p/realtimeconfigquickscan/

Note you can roll without realtime priority and still be fine, that is if you aren’t experiencing dropouts. If that is the case, make sure your CPU governore is in “performance” mode when using Renoise (the magic CPU usage number will shrink as well). I’m on Fedora 17 now, else I could point you to something Ubuntu specific, can’t imagine it’s much different:
