31 <h3>1.&nbsp; Introduction</h3>
32 The LinuxSampler development team is happy to announce the release of
33 a new version of LinuxSampler of Mac OS X. More information will be added here soon, so check back frequently.<br>
34 <br>
35 For now the sampler supports the CoreMIDI interface
36 for MIDI input and <A HREF="http://www.jackosx.com">jack</A> for audio out. This means it currently runs only
37 as a standalone application. An AU/VST interface will follow at a later stage, along with
38 a network module to run multiple sampler slaves distributed on OS/X, Windows or
39 Linux machines (Linux provides better performance) all controlled from a
40 OS X or Windows box i.e. running the AU / VST sequencer.<br>
41 Even though LinuxSampler presently runs only as standalone app,
42 thanks to jack you can comfortably route the sampler's audio outs back into your sequencer.
43 <br>
44 LinuxSampler is implemented as a client/server application. This means
45 the sampling engine (the server / backend) runs
46 independently from the GUI (the client / frontend). Sampling engine and
47 client can be run on the same box or on different machines too, connected
48 over the network.<br>
49 <br>
50 The Mac OS X version provides all the features of the Linux version
51 since it is built from the same source code base.
52 This means when new features will come out the
53 Mac OS X version will usually provide the same feature set as the Linux
54 version. This was made possible by the very modular design of both
55 low level, operating system functions and flexible audio / MIDI driver
56 system.<br>
57 <br>
58 The Mac OS X version comes as an easy to install DMG file which will
59 install all the necessary modules to run both the server ( bin/linuxsampler )
60 and the GUI client. For now it installs only the qsampler GUI client
61 as JSampler, the sampler frontend written in Java requires Java 1.6 which is not
62 available on OS X yet. Of course you can run JSampler on a Windows or Linux box
63 connected over the network to your OS X box or you could try to run it in a windows
64 virtual machine. We discourage running a virtual machine along with the sampler
65 as both applicationes are very CPU and RAM hungry therefore the performance
66 of LinuxSampler will be suboptimal.<br>

71 <a name="requirements"></a>
72 <h3>2.&nbsp; Requirements</h3>
73 <ul>
74 <li>PPC or Intel Mac (an Intel Mac should provide much better performance)
75 <li>Mac OS Tiger or later (Leopard should work too)</li>
76 <li><A HREF="http://www.jackosx.com">JackOSX</A>. Install it before LinuxSampler</li>
77 <li><A HREF="http://pete.yandell.com/software/">Pete Yandell's MIDI Patchbay</A> or a similar tool</li>
78 </ul>
80 <a name="installation"></a>
81 <h3>3.a&nbsp; Installation</h3>
82 <ol>
83 <li>Install <A HREF="http://www.jackosx.com">JackOSX</A>
84 (if you don't have it already).
85 </li>
86 <li>Download the latest version of the LinuxSampler Mac OS X installer
87 from the <a href="http://www.linuxsampler.org/downloads.html">LinuxSampler
88 Download Page</a>, and mount it on Finder.
89 </li>
90 <li>You will find a single folder "linuxsampler051-mac". Copy this
91 folder to wherever you like (e.g. under /Applications).
92 </li>
93 </ol>
95 <a name="using"></a>
96 <h3>4.&nbsp; Using the Applications</h3>
97 The folder contains three items, "bin", "linuxsampler" and
98 "qsampler".
99 <ol>
100 <li>Start qsampler.app. The application launches, and you
101 will see messages saying that linuxsampler is now running. After a
102 while, you will also see that the JackPilot application (installed by
103 the JackOSX installer) automatically launches showing the Jack server
104 already running.
105 </li>
106 <li>
107 Since CoreMIDI is sometimes too slow to respond when creating a new MIDI device.
108 so you need to increase "Timeout" parameter in the
109 Options:Server Settings to 10000 msec. (Added note on Jan 7, 2008: this value is now set by default)
110 </li>
111 </ol>
113 <a name="setup_midi"></a>
114 <h3>4.1&nbsp; Setting up MIDI Input</h3>
115 In qsampler click on the device configuration tab.
116 Click on the MIDI devices icon and then on Create.
117 <br>
118 <br>
119 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.
120 <br>
121 <br>
122 (You should be able to create an arbitrary number of MIDI input devices by repeating "Create", but this feature does not work well yet.)
124 <a name="setup_audio"></a>
125 <h3>4.2&nbsp; Setting up Audio Output</h3>
126 LinuxSampler currently only supports the jack driver model for audio output
127 on Mac OS X.
128 Click on AUDIO devices icon and then on Create.
129 <br>
130 You can of course save and load sampler session as LSCP files which will
131 automaticall set up audio and midi devices and load samples into the channel strips.
132 <ol>
133 <li>
134 Connect audio ports:
135 In the "Connections Manager" pane of JackPilot: linuxsampler --> Built-in audio: in1 & in2
136 or
137 In the "Connections" window of qjackctl: linuxsampler --> coreaudio<br>
138 <a href="http://download.linuxsampler.org/pix/screenshots/osx_qjackctl.jpg">
139 <img src="screenshots/osx_qjackctl_preview.png" border="0">
140 </a>
141 <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.
142 </li>
143 <li>
144 Start MIDI Patchbay.app and connect your MIDI Input instance (probably your MIDI interface or USB-enabled keyboard) to the "LinuxSampler_in_0"
145 MIDI Output<br>
146 <a href="http://download.linuxsampler.org/pix/screenshots/osx_patchbay.jpg">
147 <img src="screenshots/osx_patchbay_preview.png" border="0">
148 </a>
149 </li>
150 </ol>
152 <a name="load_samples"></a>
153 <h3>4.3&nbsp; Loading Samples</h3>
154 Click on Add Channel. A dialog will appear.
155 Select the GIG file you want to load, the instrument within the GIG file,
156 Audio device, MIDI device, MIDI port and channel.
157 Click OK.

159 <h3>5.&nbsp; Installation Troubleshooting</h3>
160 TODO
162 <a name="docs"></a>
163 <h3>6.&nbsp; Detailed Documentation</h3>
164 You find more detailed documentation about our software on our official <a href="http://linuxsampler.org/documentation.html">
165 LinuxSampler documentation site</a>.
167 <a name="bugs"></a>
168 <h3>7.&nbsp; Bugs, Problems and Feature Requests</h3>
169 There could be several bugs in the Mac OS X version of LinuxSampler which we hope to root out soon.
170 Please report them using our bug tracking system:<br>
171 <br>
172 &nbsp;&nbsp;&nbsp;&nbsp;<a href="http://bugs.linuxsampler.org/">http://bugs.linuxsampler.org/</a><br>
173 <br>
174 Some bugs and problems we discovered so far:
175 <ul>
176 <li>The current LinuxSampler for Mac OS X binary distribution does not ship with gigedit yet
177 <br>
178 Toshi writes: I tried gigedit with X11 and gtk on my Mac. It worked, but the
179 installation process was too much complicated for ordinary users (so
180 complicated that I cannot remember exactly how I did that myself). We
181 still have a long way before gigedit can be part of binary distribution
182 for Mac.
183 </li>
184 <li>if you overload the sampler (CPU overload or disk overload) it
185 produces noises</li>
186 <li>
187 QSampler crashes when one tries to create a second port of jack.
188 An error dialog saying the device was not created, after the dialog is dismissed the QSampler crashes.
189 </li>
190 <li>
191 Another problem in QSampler. It sometimes fails to quit
192 gracefully, and I need to do "Force Quit". After force quitting, the
193 linuxsampler subprocess is still running and I need to stop it by
194 "killall linuxsampler".
195 </li>
196 <li>
197 JackPilot may not launch automatically after QSampler launches. On the other hand, if it is already running, the screen of JackPilot may not display correctly the current status of the jack daemon. In such cases please quit and restart JackPilot manually.
198 </li>
199 </ul>
