   −
The easier way of connecting your Zynthian is to use the Ethernet RJ45 connector with a CAT-5 cable to connect your unit to your local network or directly to your computer (Ethernet to Ethernet). Your Zynthian box uses the link-local name "zynthian.local" and its files can be accessed with '''sftp''' and '''scp''' (If you are using Windows, get '''Winscp''' - free software needed to communicate using this Internet protocol).

The easiest way to connect your Zynthian is to use the Ethernet RJ45 connector with a CAT-5 cable to connect your unit to your local network (DHCP) or directly to your computer (Ethernet to Ethernet, aka link-local). Your Zynthian box uses the link-local name "zynthian.local" and the filesystem can be accessed with '''sftp''' and '''scp''' (If you are using Windows, use '''Winscp''' - free software needed to communicate using this Internet protocol).

You can also login with '''ssh''' to access the Linux console. see [[Command_Line_User_Guide]] (use '''PuTTY''' for Windows). The username and default password is:
    
  user=root
 
  user=root
 
  password=raspberry
 
  password=raspberry
   −
If the link-local address (zynthian.local) is not found, test that the link-local feature is enabled in your system. Sometimes is disabled and local names are not recognized (i.e. on Windows).
+
If the link-local address (zynthian.local) is not found, make sure that the link-local feature is enabled in your system. Sometimes it's disabled and link-local names are not recognized (windows). If you can't manage to get link-local names to work, you can use the Zynthian's IP address.  The zynthian's IP address can be found int the UI's "Admin->Network Info" menu, and it's also printed on the zynthian's error screen. See: [[Finding your IP address]]
−
Instead, you can use the Zynthian's IP address.  Find out what that is using the "Network Info" utility in the Zynthian's Admin menu. or See: [[Finding your IP address]]  
+
 
 +
== Wifi Hotspot ==
 +
 
 +
You can connect to your Zynthian using the built-in Wifi Hotspot mode. This is less convenient than using Ethernet or an existing Wifi network, and is mostly useful to configure connections to other wifi networks.
 +
 
 +
# Open the Admin screen on your Zynthian.
 +
# Select the "Wifi Hotspot" option.
 +
#* This will take up to thirty seconds to complete.
 +
# Connect to the "zynthian" network with another device.
 +
# In the Admin screen on your Zynthian, select "Network Info".
 +
# Connect to the displayed IP address with the browser on your other device.
 +
 
 +
Note that the wifi network created in hotspot mode allows anyone to connect. If using the wifi hotspot in a public place, ensure you've changed your Zynthian password.

[[Configuring_Audio_Devices]]
+
You can access the MOD-UI web interface using the web browser from your computer:
   −
== Accessing the MOD-UI web interface ==
+
* Create a Special Layer with a "MOD-UI" engine from the Zynthian's UI
 +
* Connect your Zynthian to your local network using the ethernet connector (RJ45) or directly to your computer (ethernet to ethernet)
 +
* Open the browser in your computer and navigate to:
 +
 
 +
zynthian.local:8888
 +
 
 +
The MOD-UI webpage should appear.
 +
 
 +
When a MOD-UI layer exist, this link is also accessible from the webconf's software menu (reload webconf after creating the layer).
 +
 
 +
If the link-local address (zynthian.local) is not found, test that the link-local feature is enabled in your system. Sometimes is disabled and local names are not recognized. You can use the zynthian's IP address instead. See: [[Finding your IP address]]
 +
 
 +
== Viewing Zynthian UI and Synth Engine Native GUIs on your Computer ==
 +
 
 +
Some engines have a native GUI that can be accessed from your desktop/laptop computer. Zynthian provides a VNC viewer for a desktop that allows access to these native GUI. By default VNC is disabled and it is recommended to disable for performance (as it has a small overhead which is best saved for your audio). To enable VNC and access the desktop and engines' native GUI:
 +
 
 +
* Connect via web browser to webconf
 +
* Navigate to INTERFACE->UI Options
 +
* Assert Enable VNC Server option and press Save
 +
* Reload webconf and navigate to INTERFACE->UI-Engines
 +
* Enter the Zynthian password (default: raspberry)
   −
If you have a recent zynthian image with MOD integration (Gorgona or later), you can access the MOD-UI web interface using the web browser from your computer:
+
Note: There is also an option to access the Zynthian main UI by navigating to INTERFACE-VNC UI. This is a mirror of the main UI and may be driven from VNC and/or the physical interface.
   −
# Connect your Zynthian to your local network using the ethernet connector (RJ45) or directly to your computer (ethernet to ethernet)
+
The VNC views may be accessed directly via the URLs:
−
# Open the browser in your camputer and type in the address bar:
     −
zynthian.local:8888
+
* http://zynthian.local:6080/vnc.html (Main UI)
 +
* http://zynthian.local:6081/vnc.html (Engines desktop)
   −
The MOD-UI webpage should appear. Enjoy! ;-)
+
or with a VNC client by connecting to ports:
   −
If the link-local address (zynthian.local) is not found, test that the link-local feature is enabled in your system. Sometimes is disabled and local names are not recognized.
+
* 5900 (Main UI)
−
Instead, you can use the zynthian's IPaddress.  Find out what that is using the "Network Info" utility in the Zynthian's Admin menu.
+
* 5901 (Engines desktop)software can be launched, like ''qjackctl'' or a virtual MIDI keyboard for testing.
   −
== Opening Synth Engine Native GUIs in your Computer ==
+
Tip: You can automatically connnect and login to web-based VNC by appending parameters to the URL, e.g. http://zynthian.local:6080/vnc.html?autoconnect=true&password=raspberry
   −
Some engines have a native GUI that can be accessed from your desktop/laptop computer. There are several methods for achieving this:
+
====Supported Engines with Native GUI====
   −
===X11 Server===
+
Currently ''ZynAddSubFX'', ''Aeolus'', ''Pianoteq'' and ''Pure Data'' have support for remotely displaying their native GUIs, which is launched automatically when layer is created. Other GUI
 +
{{NoteBox|Using an ethernet-to-ethernet (cable) connection will reduce remote GUI latency and improve usability.}}
   −
For using this method, you need an X11 Server running on your desktop/laptop computer.
+
== Uploading your presets/soundfonts to Zynthian ==
   −
* If you use Linux, probably you already have it, so you don't need to do nothing special. Simply login into your zynthian using the ssh with the "-Y" option for forwarding the X session:
+
The easiest way of getting your presets & soundfonts inside your zynthian is by using the webconf's preset manager:
   −
  $ ssh -Y root@zynthian.local
+
  http://zynthian.local/lib-presets
   −
* If you are a "Mac" user, you should install and enable the '''XQuartz''' package. After that, login into your zynthian with the same command.
+
From there you manage your preset & soundfont libraries: renaming, deleting, and uploading, including automatic conversion from some native formats:
   −
* If you are a "Windows" user, then you should install the '''XMing''' package and login into your zynthian using Putty with the "X11 forwarding" option enabled.
+
* DX7 SysEX files
 +
* OBXd FXB files
 +
* synthv1 native format
 +
* padthv1 native format
   −
[[File:Putty-on-zynth-X11.png]]
+
If if this doesn't work for you, or you prefer to do it by hand, you can copy your presets/soundfonts/pedalboards into the next folder:
   −
===VNC===
+
/zynthian/zynthian-my-data
   −
You also could use VNC on any platform, although it's slighty complex:
+
This is the subfolder structure:
   −
* Login into your zynthian box and enter:
+
+ '''presets'''
 +
  + zynaddsubfx
 +
  + puredata
 +
  + pianoteq
 +
  + lv2
 +
  + mod-ui
 +
+ '''soundfonts'''
 +
  + '''sf2'''
 +
    + bank-1.sf2
 +
    + ...
 +
    + bank-n.sf2
 +
  + '''sfz'''
 +
    + bank-1
 +
      + sfz-bundle1
 +
      + ...
 +
      + sfz-bundle2
 +
    + ...
 +
    + bank-n
 +
  + '''gig'''
 +
    + bank-1
 +
      + instrument-1.gig
 +
      + ...
 +
      + instrument-n.gig
 +
    + ...
 +
    + bank-n
 +
+ '''snapshots'''
 +
+ '''capture'''
   −
  # apt-get install vnc4server blackbox
+
SFZ and GIG soundfonts are used with LinuxSampler. SF2 soundfonts are used with FluidSynth. SFZ and GIG soundfonts must be organized in 'bank' subfolders. SF2 files are considered "banks" by itself.
−
  # pico ~/.vncrc
     −
* enter this line to set the desktop size:
+
If you have doubts of how to store your data, take a look in this directory:
   −
    $geometry = “2048x1600”;
+
/zynthian/zynthian-data
   −
* start the vnc server:
+
Here you will find the same folder structure, and could help you to understand.
   −
  # vnc4server
+
Also it's interesting:
   −
* Connect to the vnc server using (e.g.) windows TightVNC viewer.
+
/zynthian/config
   −
===Supported Engines with Native GUI===
+
If you are really interested, you could, for instance, edit the setBfree configuration, and change the CC assignments, etc.
   −
Currently ''ZynAddSubFX'', ''Aeolus'' and ''Pure Data'' have support for native GUI, that is launched automatically when layer is created. Other GUI software can be launched, like ''qjackctl'' or a virtual MIDI keyboard for testing. Support for Soundfont GUI using ''Polyphone'' will be added in the future ;-)
+
{{WarningBox|If you add or change something inside the ''zynthian-data'' folder, your changes will be lost on the next update, or, in a worst case scenario, you could break the update system.}}
   −
'''IMPORTANT:''' Using an ethernet-to-ethernet (cable) connection will reduce latency and improve usability.
+
== OSC ==
   −
== Copying your presets/soundfonts to Zynthian ==
+
Open Sound Control (OSC) is a protocol for networking sound synthesizers, computers, and other multimedia devices for purposes such as musical performance or show control. Zynthian implements OSC in various ways.
   −
You can copy your presets/soundfonts/pedalboards in the next forlder:
+
==== CUIA: Callable User Interface Actions ====
 +
The CUIA is an unidirectional remote API that can be used to send simple control messages to zynthian UI. The CUIA can be accessed in several ways, as described in the [[Zynthian_UI_Users_Guide#CUIA:_Callable_UI_Actions|user's guide]] and this section explains how to access the CUIA using OSC on port UDP 1370.
   −
/zynthian/zynthian-my-data
+
The OSC base path for CUIA messages is:
   −
There are different subfolders:
+
/cuia
   −
+ mod-pedalboards
+
Example:
−
+ soundfonts
+
  /cuia/restart_ui
−
  + gig
  −
  + sfz
  −
  + sf2
  −
+ snapshots
  −
  + zynbanks
     −
In 'mod-pedalboards' you will find your stored MOD-UI pedalboards.
+
Note that CUIA paths are case insensitive, e.g.
−
Use SFZ and GIG soundfonts with LinuxSampler. SF2 soundfonts must be used with FluidSynth. SFZ and GIG fonts must be stored in 'category' subfolders.
+
/cuia/reboot
−
User's ZynAddSubFX presets/banks must be stored in the "zynbanks" directory.
     −
If you have doubts of how to store your data, take a look in this directory:
+
is interpreted the same as
 +
/CUIA/REBOOT
   −
  /zynthian/zynthian-data
+
Some examples using the command line tool "send_osc":
 +
  # send_osc 1370 /CUIA/SCREEN_MAIN
 +
# send_osc 1370 /CUIA/LAYER_CONTROL 2
   −
Here you will find the same folder structure, with some additions.
+
An example Python script to start a MIDI recording:
 +
import liblo
 +
liblo.send(('zynthian.local', 1370), "/CUIA", ('s', 'START_MIDI_RECORD'))
   −
If you are really interested, you could, for instance, edit the setBfree configuration, and change the CC assignments, etc.
+
And finally, the full list of CUIAs:
   −
'''IMPORTANT:''' after adding or changing something in 'zynthian-data', you can’t update the zynthian-library from the Admin menu. (The "git-based" updating system should be improved...)

==== TouchOSC ====
−
  password=raspberry
+
The TouchOSC protocol is supported if the option is enabled in the Zynthian admin menu. This accepts OSC on port 12101 using UDP datagrams and includes raw MIDI data interpretation on OSC path
 +
/midi
 +
This path accepts an OSC MIDI type message. An example Python script to send MIDI note on / off messages:
 +
import liblo
 +
import time
 +
   
 +
cmdNoteOn = 0x90
 +
cmdNoteOff = 0x80
 +
note = 60
 +
  vel = 100
 +
 +
liblo.send(('zynthian.local', 12101), "/midi", ('m', (vel,note,cmdNoteOn,0)))
 +
time.sleep(1)
 +
liblo.send(('zynthian.local', 12101), "/midi", ('m', (0,note,cmdNoteOff,0)))
