<h3>1. Introduction</h3> |
| 41 |
|
| 42 |
The LinuxSampler development team is delighted to announce the release of LinuxSampler-1.0.0 for Mac OS X. |
| 43 |
LinuxSampler is an open-source disc-streaming software sampler that enables the expressive emulation |
| 44 |
of instruments by the means of MIDI-triggered rendering of large sample sets. While the modular design |
| 45 |
of LinuxSampler allows for multi-engine and multi-format features, the present implementation of the Gig |
| 46 |
engine already has the capability for producing virtual instruments with realistic emulations. VST (Linux, Windows) |
| 47 |
and Audio Unit (OS X) plug-ins for digital audio workstations (DAWs) facilitate the use of this sampler within audio |
| 48 |
and MIDI sequencer applications. With its LinuxSampler Control Protocol (LSCP), LinuxSampler can be controlled over |
| 49 |
a computer network so that a cluster can be used as a gigantic sampler. Since this network protocol is ASCII-based, |
| 50 |
frontends for it can be written in any programming language and for any operating system. LinuxSampler itself is a server |
| 51 |
application that can be controlled by GUI frontends like the C++-based Qsampler and the Java-implemented Fantasia. The |
| 52 |
present release can be deployed on Linux, OS X and Windows. The instructions for using the OS X binaries are outlined here. |

| 56 |
<h3>2. Requirements</h3> |
| 57 |
<ul> |
| 58 |
<li>PPC or Intel Mac |
| 59 |
<li>Mac OS X Leopard and Snow Leopard </li> |
| 60 |
<li> For the LinuxSampler(JACK) package: <A HREF="http://www.jackosx.com">JackOSX</A>. Install it before LinuxSampler(JACK)</li> |
| 61 |
<li><A HREF="http://www.apple.com/downloads/macosx/audio/midipatchbay.html">Pete Yandell's MIDI Patchbay</A> </li> |
| 62 |
</ul> |
| 63 |
|
| 64 |
<a name="installation"></a> |
| 65 |
<h3>3. The LinuxSampler package</h3> |
| 66 |
<ol> |
| 67 |
|
| 68 |
<li>Combined binaries of LinuxSampler and its derivatives for both Intel- and PowerPC-based Apple |
| 69 |
machines can be obtained by downloading the "LinuxSampler-1.0.0-OS_X.universal.dmg" disk image |
| 70 |
from the <a href="http://www.linuxsampler.org/downloads.html">LinuxSampler |
| 71 |
Download Page</a>. |
| 72 |
</li> |
| 73 |
<br> |
| 74 |
<li> After mounting and extracting the contents of the disk image on your computer's desktop, |
| 75 |
open the "linuxsampler-1.0.0" volume. The following choices are available: |
| 76 |
</li> |
| 77 |
<ol><ol> |
| 78 |
<br> |
| 79 |
<img src="screenshots/linuxsampler-1-0-0-dmg.png" border="0"> |
| 80 |
</ol></ol></ol> |
| 81 |
<br> |
| 82 |
<li> This disk image contains two sets of universal binaries. The first set designated simply <i>LinuxSampler</i> is linked to |
| 83 |
Apple's proprietary CoreAudio driver while the second <i>LinuxSampler(JACK)</i> folder contains binaries linked to the |
| 84 |
third-party JACK (Jack Audio Connection Kit) audio server framework. In addition there is also the <i>LinuxSamplerAU.component</i> |
| 85 |
Audio Unit plug-in which can be used within OS X-deployed DAWs for loading up virtual instruments. |
| 86 |
</li> |
| 87 |
<br> |
| 88 |
The <i>LinuxSampler</i> folder contains the triple-architecture (ppc/i386/x86_64) universal binaries of "linuxsampler" and the |
| 89 |
"LinuxSamplerAU.component" DAW plug-in. |
| 90 |
<br><br> |
| 91 |
The <i>LinuxSamplerAU.component</i> plug-in should be dragged and dropped into the /Library/Audio/Plug-Ins/Components folder as |
| 92 |
shown by the rightward arrow. In a similar way, place the <i>LinuxSampler</i> folder into the /Applications folder |
| 93 |
<ol><ol> |
| 94 |
<h3>3.1. Loading a Virtual Instrument in your DAW</h3> |
| 95 |
<li> For a basic demonstration, we will load up the LinuxSamplerAU plug-in into GarageBand. First open the "Track Info" window: |
| 96 |
Track / Show track Info. Then in the Track Info window select "LinuxSampler Unit" from the "Generator" tab. |
| 97 |
</li> |
| 98 |
<br> |
| 99 |
</ol></ol> |
| 100 |
<img src="screenshots/garageband-trackinfo.jpg"" border="0"> |
| 101 |
<br><br> |
| 102 |
<li> A gig file can then be loaded using the "qsampler" or "Fantasia" application. Click on the "Add channel" icon |
| 103 |
in qsampler in order to load a gig file. |
| 104 |
|
| 105 |
|
| 106 |
</li> |
| 107 |

| 111 |
<br><br> |
| 112 |
You are now ready to lay down your track... |
| 113 |
<br><br> |
| 114 |
(Note: JackOSX installation is NOT recommended in this setup since the Jack Audio Connection Kit hinders the initialization |
| 115 |
of both <i>qsampler</i> and <i>Fantasia</i>.) |
| 116 |
</ol></ol> |
| 117 |
<h3>5. The LinuxSampler(JACK) package</h3> |
| 118 |
</ol> |
| 119 |
<li> |
| 120 |
This archive contains dual-architecture ppc/i386 binaries of <i>linuxsampler</i> and "qsampler" which function together with |
| 121 |
<A HREF="http://www.jackosx.com">JackOSX</A>. This setup can be used for running various Jack-enabled applications simultaneously: a setup |
| 122 |
that is particularly useful for live situations. |
| 123 |
</li> |
| 124 |
<br> |
| 125 |
<li> |
| 126 |
After opening the linuxsampler-1.0.0 volume, place the <i>LinuxSampler(JACK)</i> folder into the /Applications directory as |
| 127 |
indicated by the leftward arrow at the bottom. |
| 128 |
</li> |
| 129 |
<ol><ol> |
| 130 |
<br> |
| 131 |
<img src="screenshots/linuxsampler-1-0-0-dmg.png" border="0"> |
| 132 |
<a name="setup_midi"></a> |
| 133 |
<h3>4.1 Setting up MIDI Input</h3> |
| 134 |
In qsampler click on the "Device configuration" icon and then on Create. |
| 135 |
<br><br> |
| 136 |
</ol></ol> |
| 137 |
<img src="screenshots/qs_midi_device.jpg" border="0"> |
| 138 |
<br><br> |
| 139 |
If you need multiple MIDI input device, set the "Number of ports" to 2, 3, ... before creating the MIDI device. The multiple ports will be accessible from other MIDI applications as "Linuxsampler_in_0", "Linuxsampler_in_1", etc. |
| 140 |
<br> |
| 141 |
<br> |
| 142 |
(You should be able to create an arbitrary number of MIDI input devices by repeating "Create", but this feature does not work well yet.) |
| 143 |
<ol><ol> |
| 144 |
<a name="setup_audio"></a> |
| 145 |
<h3>4.2 Setting up Audio Output</h3> |
| 146 |
Start the Jack audio server using JackPilot.app. The <i>qsampler</i> application can then be launched by double-clicking on its icon. |
| 147 |
<br> |
| 148 |
|
| 149 |
<ol><br> |
| 150 |
<li> |
| 151 |
Connect audio ports: |
| 152 |
In the "Connections Manager" pane of JackPilot: linuxsampler --> Built-in audio: in1 & in2 |
| 153 |
or |
| 154 |
In the "Connections" window of qjackctl: LinuxSampler --> system<br> |
| 155 |
<br> |
| 156 |

| 159 |
</a> |
| 160 |
<br><br>Intel Mac Note: to use built-in audio in Jack, you need to create an "aggregated device" by using "Audio MIDI Setup". Please look up Jack manual for details. |
| 161 |
</li> |
| 162 |
<br> |
| 163 |
<li> |
| 164 |
Start MIDI Patchbay.app and connect your MIDI Input instance (probably your MIDI interface or USB-enabled keyboard) to the "LinuxSampler_in_0" |
| 165 |
MIDI Output<br><br> |
| 166 |
</ol></ol> |

<a name="load_samples"></a> |
| 174 |
<h3>4.3 Loading Samples</h3> |
| 175 |
Click on Add Channel. A dialog will appear. |
| 176 |
Select the GIG file you want to load, the instrument within the GIG file, |
| 177 |
Audio device, MIDI device, MIDI port and channel. |
| 178 |
Click OK. The user can then save *.lscp files for convenient future use. In this way, the user can automatically set up audio and midi devices and |
| 179 |
load samples into the channel strips when recalling a setup. |

<br> |
| 205 |
Some bugs and problems we discovered so far: |
| 206 |
<ul> |
| 207 |
<li>The current LinuxSampler for Mac OS X binary distribution does not ship with gigedit yet. |
| 208 |
While gigedit works using gtk with X11.app, the large number of dependencies |
| 209 |
on external libraries makes it very arduous to prepare a universal binary. |
| 210 |
</li> |
| 211 |
<li>Overloading the sampler (CPU overload or disk overload) |
| 212 |
produces noise.</li> |
| 213 |
<li> |
| 214 |
QSampler crashes when one tries to create a second port of jack. |
| 215 |
An error dialog saying the device was not created, after the dialog is dismissed the QSampler crashes. |
| 216 |
</li> |
| 217 |
<li> |
| 218 |
Sometimes qsampler fails to quit gracefully; this calls for "Force Quit". After force quitting, the |
| 219 |
linuxsampler subprocess is still running. In this case, simply invoke "killall linuxsampler" from Terminal.app to terminate |
| 220 |
linuxsampler. |
| 221 |
</li> |
| 222 |
|
| 223 |
</ul> |
