+                     the sampler's process and provide that application access

+                     time, thus allowing to immediately hear changes with the
+                     sampler made by the instrument editor.

+ <p>Note: consequently instrument editors are always spawned

+ Managing Effects</h3>
+ <p>Audio effects (e.g. reverb, delay, compression) can be
+                 applied to the audio signals generated by the sampler. The
+                 sampler usually provides a set of internal audio effects for
+                 this task. The exact set of effects depends on the availability
+                 of third party effect plugins installed on the system where the
+                 sampler runs on.
+ </p>
+ <p>At the moment only "send effects" are supported. Support for
+                 "insert effects" and "master effects" is planned to be added at
+                 a later point.
+ </p>
+ <p>The following commands allow to retrieve the set of internal
+                 effects available to the sampler, detailed informations about
+                 those effects and to create and destroy instances of such
+                 effects. After an instance of an effect is created, the effect
+                 instance can be inserted into the audio signal path of the
+                 sampler, e.g. as send effect.
+ </p>
+ <p>The sampler allows to create an arbitrary amount of so called
+                 send effect chains. Each effect chain can host an arbitrary
+                 amount of effect instances. The output of the first effect
+                 instance in an effect chain is fed to the input of the second
+                 effect instance of the chain and so on. So effects in one chain
+                 are processed sequentially. Send effect chains however are
+                 processed in parallel to other send effect chains. Audio signals
+                 of sampler channels are fed to send effects by creating FX sends
+                 to the respective sampler channel and assigning a destination
+                 send effect to that FX by using the
+                 <a class='info' href='#SET FX_SEND SEND_EFFECT'>"SET FX_SEND SEND_EFFECT"<span> (</span><span class='info'>Assigning destination effect to an effect send</span><span>)</span></a>
+                 command. The latter allows to route the FX send to the beginning
+                 of a send effect chain, as well as directly to any other
+                 position of the send effect chain.

+- 255). The same group of younger protocols also support
+                 escape sequences, but only for certain, explicitly declared
+                 parts of the protocol. The supported escape sequences are
+                 defined as follows:

+ <p>Notice: due to the transition of certain parts of the
+                 protocol which now support escape sequences, a slight backward
+                 incompatibility to protocols version v1.1 and younger has been
+                 introduced. The only difference is that in parts of the protocol
+                 where escape characters are now supported, a backslash characters
+                 MUST be escaped as well (that is as double backslash), whereas
+                 in the old versions a single backslash was sufficient.
+ </p>
+ <p>The following LSCP commands support escape sequences as part
+                 of their filename / path based arguments and / or may contain
+                 a filename / path with escape sequences in their response:

+                 Note that the forward slash character ('/') has a special meaning in
+                 filename / path based arguments: it acts as separator of the nodes in
+                 the path, thus if a directory- or filename includes a forward slash
+                 (not intended as path node separator), you MUST escape that slash
+                 either with the respective hex escape sequence ("\x2f") or with the
+                 respective octal escape sequence ("\057").
+ </p>
+ <p>
+                 Note for Windows: file path arguments in LSCP are expected
+                 to use forward slashes as directory node separator similar
+                 to Unix based operating systems. In contrast to Unix however
+                 a Windows typical drive character is expected to be
+                 prefixed to the path. That is an original Windows file path
+                 like "D:\Sounds\My.gig" would become in LSCP:
+                 "D:/Sounds/My.gig".
+ </p>
+ <p>
+                 The following LSCP commands even support escape sequences as
+                 part of at least one of their text-based arguments (i.e. entity name,
+                 description) and / or may contain escape sequences in at least one of
