[LAU] syncing ardour with rosegarden thorn

by Dieter Plaetinck

Hi guys, using: ardour 2.8.7 rosegarden thorn (tried both official release and latest svn version) jackd version 0.116.2 tmpdir /dev/shm protocol 24 (started as `/usr/bin/jackd -dalsa -dhw:0 -r48000 -p512 -n8`) ArchLinux 32bit (default kernel) I try to sync the transports, so that both play at the same time. In rosegarden, "edit->preferences->use jack transport" is enabled In ardour, I set 'time master' on, and tried both the 'internal' and 'jack' sync source. but when i play/pause etc in ardour, nothing happens in rosegarden. How can i make this work? thanks, Dieter

[LAU] RF noise suppression?

by Rick Green

I'm using a FOcusrite Saffire pro 26 I/O with ffado, jack, and Ardour to make multitrack recordings of live concerts, to my emachines M6810 laptop running ubuntustudio. I'm plagued by noise that sounds to me like RF interference from the laptop, getting into the audio portions of the interface. It's most obvious when I'm at home trying to mix down my recordings, as its almost constant in my monitors and most noticable in a quiet room, but it also manifests itself sometimes during shows, showing up on the input lines to the interface, which are plugged 'half-way' into the FOH mixer's channel inserts, so it invades the PA and the performers' monitors. WHen that happens, I've no other choice but to abandon the recording and shut down the laptop. Has anyone else encountered this problem? Got any suggestions how to filter it? I'm going to try some ferrite cores snapped around the firewire cable first. Anything else I might try? -- Rick Green "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." -Benjamin Franklin "As for our common defense, we reject as false the choice between our safety and our ideals." -President Barack Obama 20 Jan 2009

[LAU] Netjack2 and fast/normal/slow modes

by tyranorl＠free.fr

Hello, I'm using Netjack2 between two machines, on a local network (ad-hoc) composed of this only two machines. I only want to send transport and MIDI data over the network. However I configure the slave mode, I receive message on the master telling me that the data are received too late: (slow mode) Warning : 'SCSTAGE' runs in slow network mode, but data received too late (3 cycle(s) offset) (normal mode) 'SCSTAGE' can't run in normal network mode, data received too late (6 cycle(s) offset) sometimes combined with this other message: NetMaster : overloaded, skipping receive from 'SCSTAGE' (only when using a MIDI output port on the slave) I use jackdmp svn turnk version and jackdmp 1.9.5 and 1.9.4 (this problems comes with all of these versions), in realtime mode on both machines, with a self compiled kernel on a Debian Squeeze system. Master is running jackdmp with FFADO 2.1 drivers for a Focusrite Saffire Pro 40 interface, with 64 samples per buffer on 2 or 3 buffers (2 is fine, 3 is safe!) at 48000Hz. RT priorities and permissions are OK. Hardware setup is quite the same on both machines: Proc: Intel Q6600 (Quad Core 2.4GHz) RAM: 8Gb on the master 4Gb on the slave Motherboard: Asus P5K-V, with gigabit network ethernet adapter: 01:00.0 Ethernet controller: Attansic Technology Corp. L1 Gigabit Ethernet Adapter (rev b0) I really don't understand why I get such warnings, as my setup is quite fine (I feel), considering audio, processors/ram, and network. Perhaps something to do with MTU, but I'm not really skilled about this! Any idea of what I should try? Thanks a lot.

[LAU] Linux mastering services?

by Ken Restivo

We're almost done with a 12-track, 40-minute-long CD, recorded partially in Ardour and mixed entirely in Ardour. We should probably get it mastered. However, "pro" mastering houses want like $500 for a CD. We haven't made that much money in a year. I think we spent a total of $80 on recording it. So, not likely that we'll be justify big bucks to get it mastered. I suppose I could run it through Jamin myself, and just hope for the best, but I don't know squat about mastering. Are there any Linux-based mastering engineers around (i.e. on this list) who'd want to take on a project like this, for a rate that we might be able to actually justify? -ken

[LAU] CC for dummies

by Atte André Jensen

Hi I don't understand the CC license at all. I could dig through a jungle starting with google, and I *have* read and understood the basics regarding CC. I'm hoping for some personal experiences in plain language. Here goes: 1) What's the advantages for the artist with CC compared to "All rights reserved". 2) What's the disadvantages for the artist with CC compared to "All rights reserved". 3) What's the advantages for the consumer with CC compared to "All rights reserved". I assume there's no disadvantages for the customer with CC... Thanks in advance for any input. -- Atte http://atte.dk http://modlys.dk

[LAU] audio setup for debian squeeze

by Rustom Mody

Hi folks Ive finally managed to migrate lenny to squeeze. I started the migration because (among other things) ardour seemed to be available only for squeeze and not lenny but got stuck for many reasons In the process I gathered that debian-multimedia is not necessary for squeeze -- so currently its removed from my sources.list So my questions 1. Is this (no debian-multimedia) a right choice? 2. Is there some (small set of) umbrella packages like ubuntu-studio? 3. Any docs recommended for the noob? I want to study jack and ardour. Thanks Rustom
