<h3>1. Introduction</h3> |
| 46 |
|
|
The LinuxSampler development team is happy to announce the release of |
| 47 |
|
|
a new version of LinuxSampler of Mac OS X. More information will be added here soon, so check back frequently.<br> |
| 48 |
|
|
<br> |
| 49 |
|
|
For now the sampler supports the CoreMIDI interface |
| 50 |
|
|
for MIDI input and <A HREF="http://www.jackosx.com">jack</A> for audio out. This means it currently runs only |
| 51 |
|
|
as a standalone application. An AU/VST interface will follow at a later stage, along with |
| 52 |
|
|
a network module to run multiple sampler slaves distributed on OS/X, Windows or |
| 53 |
|
|
Linux machines (Linux provides better performance) all controlled from a |
| 54 |
|
|
OS X or Windows box i.e. running the AU / VST sequencer.<br> |
| 55 |
senoner |
1615 |
Even though LinuxSampler presently runs only as standalone app, |
| 56 |
|
|
thanks to jack you can comfortably route the sampler's audio outs back into your sequencer. |
| 57 |
senoner |
1614 |
<br> |
| 58 |
|
|
LinuxSampler is implemented as a client/server application. This means |
| 59 |
|
|
the sampling engine (the server / backend) runs |
| 60 |
|
|
independently from the GUI (the client / frontend). Sampling engine and |
| 61 |
|
|
client can be run on the same box or on different machines too, connected |
| 62 |
|
|
over the network.<br> |
| 63 |
|
|
<br> |
| 64 |
|
|
The Mac OS X version provides all the features of the Linux version |
| 65 |
|
|
since it is built from the same source code base. |
| 66 |
|
|
This means when new features will come out the |
| 67 |
|
|
Mac OS X version will usually provide the same feature set as the Linux |
| 68 |
|
|
version. This was made possible by the very modular design of both |
| 69 |
|
|
low level, operating system functions and flexible audio / MIDI driver |
| 70 |
|
|
system.<br> |
| 71 |
|
|
<br> |
| 72 |
|
|
The Mac OS X version comes as an easy to install DMG file which will |
| 73 |
nagata |
1634 |
install all the necessary modules to run both the server ( bin/linuxsampler ) |
| 74 |
senoner |
1615 |
and the GUI client. For now it installs only the qsampler GUI client |
| 75 |
|
|
as JSampler, the sampler frontend written in Java requires Java 1.6 which is not |
| 76 |
|
|
available on OS X yet. Of course you can run JSampler on a Windows or Linux box |
| 77 |
senoner |
1614 |
connected over the network to your OS X box or you could try to run it in a windows |
| 78 |
|
|
virtual machine. We discourage running a virtual machine along with the sampler |
| 79 |
|
|
as both applicationes are very CPU and RAM hungry therefore the performance |
| 80 |
schoenebeck |
1630 |
of LinuxSampler will be suboptimal.<br> |

<h3>2. Requirements</h3> |
| 87 |
|
|
<ul> |
| 88 |
|
|
<li>PPC or Intel Mac (an Intel Mac should provide much better performance) |
| 89 |
|
|
<li>Mac OS Tiger or later (Leopard should work too)</li> |
| 90 |
|
|
<li><A HREF="http://www.jackosx.com">JackOSX</A>. Install it before LinuxSampler</li> |
| 91 |
senoner |
1633 |
<li><A HREF="http://pete.yandell.com/software/">Pete Yandell's MIDI Patchbay</A> or a similar tool</li> |

</ul> |

<a name="installation"></a> |
| 95 |
|
|
<h3>3.a Installation</h3> |
| 96 |
schoenebeck |
1618 |
<ol> |
| 97 |
|
|
<li>Install <A HREF="http://www.jackosx.com">JackOSX</A> |
| 98 |
|
|
(if you don't have it already). |
| 99 |
|
|
</li> |
| 100 |
|
|
<li>Download the latest version of the LinuxSampler Mac OS X installer |
| 101 |
|
|
from the <a href="http://www.linuxsampler.org/downloads.html">LinuxSampler |
| 102 |
|
|
Download Page</a>, and mount it on Finder. |
| 103 |
|
|
</li> |
| 104 |
nagata |
1634 |
<li>You will find a single folder "linuxsampler051-mac". Copy this |
| 105 |
schoenebeck |
1618 |
folder to wherever you like (e.g. under /Applications). |
| 106 |
|
|
</li> |
| 107 |
|
|
</ol> |
| 108 |
|
|
|
| 109 |
|
|
<a name="using"></a> |
| 110 |
|
|
<h3>4. Using the Applications</h3> |
| 111 |
senoner |
1615 |
The folder contains three items, "bin", "linuxsampler" and |
| 112 |
senoner |
1628 |
"qsampler". |
| 113 |
|
|
<ol> |
| 114 |
|
|
<li>Start qsampler.app. The application launches, and you |
| 115 |
senoner |
1615 |
will see messages saying that linuxsampler is now running. After a |
| 116 |
|
|
while, you will also see that the JackPilot application (installed by |
| 117 |
|
|
the JackOSX installer) automatically launches showing the Jack server |
| 118 |
|
|
already running. |
| 119 |
senoner |
1628 |
</li> |
| 120 |
|
|
<li> |
| 121 |
|
|
Since CoreMIDI is sometimes too slow to respond when creating a new MIDI device. |
| 122 |
|
|
so you need to increase "Timeout" parameter in the |
| 123 |
nagata |
1638 |
Options:Server Settings to 10000 msec. (Added note on Jan 7, 2008: this value is now set by default) |
| 124 |
senoner |
1628 |
</li> |

|
|
<a name="setup_midi"></a> |
| 128 |
|
|
<h3>4.1 Setting up MIDI Input</h3> |
| 129 |
|
|
In qsampler click on the device configuration tab. |
| 130 |
|
|
Click on the MIDI devices icon and then on Create. |
| 131 |
|
|
<br> |
| 132 |
|
|
<br> |
| 133 |
nagata |
1634 |
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. |
| 134 |
|
|
<br> |
| 135 |
|
|
<br> |
| 136 |
|
|
(You should be able to create an arbitrary number of MIDI input devices by repeating "Create", but this feature does not work well yet.) |
| 137 |

|
|
<a name="setup_audio"></a> |
| 139 |
|
|
<h3>4.2 Setting up Audio Output</h3> |
| 140 |
|
|
LinuxSampler currently only supports the jack driver model for audio output |
| 141 |
|
|
on Mac OS X. |
| 142 |
|
|
Click on AUDIO devices icon and then on Create. |
| 143 |
|
|
<br> |
| 144 |
senoner |
1628 |
You can of course save and load sampler session as LSCP files which will |
| 145 |
|
|
automaticall set up audio and midi devices and load samples into the channel strips. |

Connect audio ports: |
| 149 |
|
|
In the "Connections Manager" pane of JackPilot: linuxsampler --> Built-in audio: in1 & in2 |
| 150 |
|
|
or |
| 151 |
schoenebeck |
1630 |
In the "Connections" window of qjackctl: linuxsampler --> coreaudio<br> |

There could be several bugs in the Mac OS X version of LinuxSampler which we hope to root out soon. |

Some bugs and problems we discovered so far: |
| 196 |
|
|
<ul> |
| 197 |
|
|
<li>The current LinuxSampler for Mac OS X binary distribution does not ship with gigedit yet |
| 198 |
|
|
<br> |
| 199 |
|
|
Toshi writes: I tried gigedit with X11 and gtk on my Mac. It worked, but the |
| 200 |
|
|
installation process was too much complicated for ordinary users (so |
| 201 |
|
|
complicated that I cannot remember exactly how I did that myself). We |
| 202 |
|
|
still have a long way before gigedit can be part of binary distribution |
| 203 |
|
|
for Mac. |
| 204 |
|
|
</li> |
| 205 |
|
|
<li>if you overload the sampler (CPU overload or disk overload) it |
| 206 |
|
|
produces noises</li> |
| 207 |
|
|
<li> |
| 208 |
|
|
QSampler crashes when one tries to create a second port of jack. |
| 209 |
|
|
An error dialog saying the device was not created, after the dialog is dismissed the QSampler crashes. |
| 210 |
|
|
</li> |
| 211 |
|
|
<li> |
| 212 |
|
|
Another problem in QSampler. It sometimes fails to quit |
| 213 |
|
|
gracefully, and I need to do "Force Quit". After force quitting, the |
| 214 |
|
|
linuxsampler subprocess is still running and I need to stop it by |
| 215 |
|
|
"killall linuxsampler". |
| 216 |
|
|
</li> |
| 217 |
nagata |
1634 |
<li> |
| 218 |
|
|
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. |
