    4 <p> 
    5 Mark will be demonstrating: 
    6 <ul> 
    7 <li>the Digital Audio Workstation <a href="http://ardour.org/">ardour</a></li> 
    8 <li>the <a href="http://jamin.sourceforge.net/">JAMin</a> mastering tool</li> 
    9 <li>the modular software synthesizer <a href="http://alsamodular.sourceforge.net/">alsamodularsynth</a></li> 
    10 <li>the sample based drum machine <a href="http://www.hydrogen-music.org/">hydrogen</a></li> 
    11 <li><a href="http://freqtweak.sourceforge.net/">freqtweak</a></li> 
    12 <li><a href="http://arb.bash.sh/~rah/software/jack-rack/">jack-rack</a> - Real time effects using LADSPA plug-ins</li> 
    13 <li>his barely passable keyboard playing to demonstrate some of the above</li> 
    14 </ul> 
    15 </p>

    17 <h3 id="PeterChubb">Peter Chubb: Taming your old LPs</h3> 
    18 <p> 
    19 I have around 1000 LPs in various condition, having been collecting 
    20 key recordings for 30 years or so.  LPs are delicate, bulky, and 
    21 inconvenient.  So what to do? 
    22 </p> 
    23 <p> 
    24 In this talk I'll describe how I transfer audio from LP onto digital 
    25 media, fixing the worst problems of the old LP on the way.  I'll 
    26 mention tools such as gramofile, gwc, lame,  and cdrecord.  I'll also 
    27 discuss what to look for at the input end --- the turntable, tone arm 
    28 and preamplifier; and ask for help with  sound card technology. 
    29 </p>

    31 <h3 id="SimonBurton">Simon Burton: SuperCollider and HyperSense</h3> 
    32 <p> 
    33 <ul> 
    34 <li><a href="http://www.audiosynth.com/">SuperCollider3</a> on linux: how to setup and configure with jack output on kernel+2.6</li> 
    35  
    36 <li>Sending code to the SC server</li> 
    37  
    38 <li>A brief introduction to programming SC</li> 
    39  
    40 <li>Sending OSC commands to SC from python</li> 
    41  
    42 <li>a demo of the <a href="http://arrowtheory.com/hypersense/">hypersense</a> 
    43 technology. This is a trio formed in 2003.</li> 
    44 </ul> 
    45 <p> 
    46 We use custom built USB sensor devices to control SC synthdefs over an 
    47 ethernet connection. The demo would show one (or more) of these devices 
    48 working and generating audio events in real time. 
    49 (<a href="http://arrowtheory.com/hypersense/index.html">Pictures</a>). 
    50 For this demo we may need to host the USB devices on a Mac, but SC would be 
    51 +running on a linux box. 
    52 </p>

    54 <p> 
    55 <i>Simon will be assisted by Alistair Riddell (ANU Centre for New+Media Arts).</i>

    58 <h3 id="DaveRobillard">Dave Robillard: Om, OSC, and the "LAD Philosophy"</h3> 
    59  
    60 <p> 
    61 <a href="http://www.nongnu.org/om-synth/">Om</a> is a modular synthesizer, 
    62 built to address some limitations of currently available modular synths: 
    63 subpatching, polyphony, multiple patches, realtime correctness, etc.  A 
    64 major design goal of Om was to avoid duplication of effort as much as 
    65 possible, using standard LADSPA and DSSI plugins for all DSP and 
    66 controlling the engine exclusively through the OSC (Open Sound 
    67 Control) protocol. 
    68 </p> 
    69  
    70 <p>The OSC controlled engine design means it can be used 
    71 in many different configurations, with or without a UI: 
    72 </p> 
    73  
    74 <ul> 
    75 <li>Using OSC bindings in languages such as Python to allow algorithmic patch 
    76 creation and tweaking.</li> 
    77  
    78 <li>Using multiple GUI clients simultaneously running on seperate computers 
    79 over the network, allowing one user to see the changes made by the other in 
    80 realtime, and vice-versa.</li> 
    81  
    82 <li>Building simple effects processing patches and running the engine without 
    83 a UI to perform mundane background signal processing tasks (ie global reverb and 
    84 compression)</li> 
    85  
    86 <li>Syncing effects parameters to jack transport, allowing tempo-synced processing 
    87 with applications such as SooperLooper and Seq24</li> 
    88 </ul> 
    89  
    90 <p>Demos of Om used as a normal graphical modular synth, as well as some of these more 
    91 interesting use cases will be performed.</p> 
    92  
    93 <p>The talk will focus on the advantages of this type of design strategy and  
    94 interoperability between GNU/Linux audio applications, 
    95 extending the modular ideas of Jack and the Alsa Sequencer into the realm of 
    96 OSC.</p>
