Re: Linux. How it works.

Greta Thread this,

I have been recording my trials and tribulations getting Linux to work on my Acer Aspire one Net book with upgrade Ram of 2GB and an external Soundblaster sound card.

I hav'de Reaper and amplitube live installed on windows 7 on this machine previously and the machine kept crashing the drives the CPU,s were running at Meltdown and playing hard and live was just not possible.

I experimented with Linux at the beginning of the year but went for the easy route with Windows 7 previously this netbook came with XP installed and I basically broke that, windows Blue screens and eventually a complete unrebootable mess. I installed windows 7 from scratch and then also with VMware had a bunch of virtual machines running inside my Imac which is 5 years old or so with one of the first intel chips used in Macs.

I use Logic in the I mac and run several of the Amplitubes especially Fender Amplitube and ARC for my hoe studio, when travelling I wanted a workable DAW on my net book and after being away from my mac for nearly 2 months I have a stable and working DAW on my Netbook.

Full story of process of Net book conversion here.

It has been a learning curve and Pulse Audio has been a difficulty which endures as to get skype working I tried a few fixes which revlve around this fix.

http://ubuntuforums.org/showthread.php?t=789578

2. Ensure you have the necessary PulseAudio libraries and configuration utilities installed:
Code:

$ sudo apt-get install libasound2-plugins padevchooser libsdl1.2debian-pulseaudio

3. Ensure the evil "libflashsupport" library is not installed:
Code:

$ sudo apt-get remove --purge libflashsupport flashplugin-nonfree-extrasound


Note: If you are greeted with the error "Connection failed: Connection refused", manually launch PulseAudio before opening the PulseAudio Volume Control application:
Code:

$ pulseaudio & pavucontrol

6. Ensure that your sound card's PCM mixer is not muted or set to 0% volume (this appears to be a common bug in Intrepid and Jaunty):

Code:

$ alsamixer -Dhw

Note: When the PulseAudio ALSA plugins are active, you must explicitly specify your hardware device in alsamixer (marked in blue above), otherwise it will open the PulseAudio mixer.

I have now discovered the wonderfull world of open source plug ins I have delved into it breifly in the past having read an article about the top ten amp modeling solutions but this process has led me to a different perspective as to what the Plugin world is all about and where it is happening yesterday I downloaded a fantastic TS808 plug in which I will demo at aome point but is is brilliant and has great graphics as well.

Still left with the final challenge of Getting Reaper to talk to Jackct and get my latency down Iḿ no more than a few mouse clicks away but the clicks are not obvious ones. I found a great article about setting up computers for optimal Live useage of Pluguins and Daws etc so will have another look in there. The same Article or Foru'm thread also pointed me to a lot of Plug in stuff.

Reaper also can be used in wdm or directsound modes, from its audio device preferences. Don't select jackd in winecfg when using reaper, choose alsa, and wine and wineasio should
probably both be installed by synaptic, or both compiled, but not a blend. regsvr32 wineasio.dll command must be run after installing wineasio. Wineasio must be selected in the Device preferences in Reaper, and jackd must be active...all apps run by the same user...

yada yada...no wonder analog is alive and well :)

EXCELLENT SITE AND THREAD:
viewtopic.php?f=49&t=13204

I have been blogging my experience between the Cuckos thread and a private guitar Club forum which I am a member of as The whole Linux concept is very exciting to me and I wanted to keep track of my experience to help streamline the conversion for others.

I still do not have Jack working with Reaper and suffer the latency effects of that but I am confident that I will have that cracked within the next few days.

The Linreaper installer is brilliant and the Lin reaper options loader that downloads with it took me a while to figure out.

At the moment I am using the direct sound set up and not the Wine Wineasio audio option as I can not get it hooked up with Jack as yet.

I have found that the solutions when I find them are easy to implement but the difference makes the process less intuitive for Windows uses ( those that remember and had and retain the facility for Dos, will enjoy the registry as rusk says.

I am a newly popped cherry as far as Linux goes but my experience has been very good and the system I have on this Netbook is a much better one than the windows 7 and windows XP one before it and I can do all the same things. The Native linux sound apps like guitarix and rackarack are brilliant. I am yet to teach myself how to use Ardour but it looks like it will be fun and am looking forward to playing with hydrogen.


As a non programmer but with quite a lot of experience with Logic and the commercial modelling software I have got this netbook up and running I will do a general checklist, bullet point from first to last and demo screen capture once I have the Jack issue nailed. It can be done and I would suggest patience.

I started with the new Ubuntu 11.4 then did the upgrade download through the registry for Ubuntu Studio which is brilliant and more windows like so faster for me to clic'k around in. I am now going to have a look at the upgrade to KXstudio.

My next task is to see if I can interface with my media smart server, it works with my I am at home but I have not as yet managed to log onto it which I will want to do for my Music and video film collection is on there and I need to be able to access it
which as yet I haven't managed . I'm back home to my Mac on Wednesday so should be able to get that all working of the install disc for the server which I don have with me.

I am very pleased with my new Linux based system.
A long first post Iḿ afraid but hoepfully my experience will be an encouragement and help to those interested in doing the Linux Thang!

Roger Lewis7 April 2017 at 12:56 Syria is all about Gas, not poison Sarin Gas but Gas Pipelines. It is also not about Hydro Carbons in themselves but the market for hydrocarbons and which currency contracts of supply are settled in otherwise known  as,  US petrodollar hegemony.

Meet The Fuggers, Brexit, The Euro and Clueless Elites.

Meet the Fuggers or, its the Money Power stupid. Brexit, The Euro and clueless Elites.



The Eastern Roman empire under Justinian saw the seeds of its final fall to The Ottomans when Abd El Melik started paying tribute in Gold coinage under his own Political Branding you might say.

With all the talk of Brexit being the removal of a final obstacle to the deeper federation of a European State transcending tiresome nationalism, perhaps a little review of History, particularly Monetary history, might not be such a bad thing.

In the review of European competences carried out as a consultation by the foreign office regarding Brexit and or reform requirements of the Eu, two of the papers need to be considered in the context of the Money power argument.

The first paper considered is the Subsidiarity and proportionality aspects of the Lisbon treaty and the competences of the EU institutions vis National and regional democratic institutions. This is a trade-off between Centralised Efficiency and …

Turn Out Is Key. Election 2017. High Turnout and Labour Wins!!! #VoteLabour #DriveAfreindtothePollingPlace

Link To Lord Ashcroft Polling.

This Graph Explains the Importance of Turnout to the outcome of the Election Tomorrow.

If Turnout is the 72.2% of the Brexit Referendum last year you can see that the Light Blue line shows That the middle third of the probability distribution curve on Ashcroft's polling numbers has a Tory Majority of between 20 and 60 seats.
The 2015 turnout was 66.1 % overall. around the same as 1997 general election less than the 77% for the 92 vote. Historically the 1950 and 51 elections had over 80% turnouts.

The total number of UK parliamentary electors in 2015 was 44,722,000, a fall of 1.3% from 2014. The total number of UK local government electors in 2015 was 46,204,700, a fall of 1.3% from 2014. Between 2014 and 2015, the total number of both parliamentary and local government electors fell in England, Wales and Scotland, but increased in Northern Ireland. The number of parliamentary electors fell in all regions of England between 2014 and 2015.…
