There are 3 types of clicks (push-switch actions) that can be performed, depending on how long you hold down the knob (or hold your finger on the touch-display):
* '''long click:''' more than 2 seconds
* '''long click:''' more than 2 seconds
Click actions for each knob are context dependent. Generally, the SELECT knob is used to navigate and a short click on it will select an item on a "Selector Screen". Inside a "Controller Screen", short clicks can be used to rotate between layers (LAYER knob) or between controller pages (SELECT knob). "Bold-clicks" are intended as shortcuts for jumping to some specific screens. Clicking the BACK knob generally jumps to the previous screen in the workflow sequence.

On the top-right corner there is a small area where some useful information is displayed in real time:
On the top-right corner there is a small area where some useful information is displayed in real time:
* CPU-load => A small horizontal bar on the top right.
* Audio Peak-meter or CPU-load => 1 or 2 small horizontal bars on the top right.
* MIDI-IN => Green '''M''' flag
* MIDI-IN => Blue '''M''' flag
* Xrun => Red '''X''' flag
* Xrun => Red '''warning''' flag
* Under-voltage => Red '''V''' flag
* Under-voltage => Red '''ray''' flag
* Over-temperature => Red '''T''' flag
* Over-temperature => Red '''thermometer''' flag
* Recording Audio => Red '''R''' flag
* Recording Audio => Red '''circle''' flag
* Playing Audio => Red '''>''' flag
* Playing Audio => Green '''play''' flag
The Audio Peak-meter is shown by default. The meter covers the range -50dBFS to 0dBFS, i.e. maximum permissible level at full scale (far right) down to 50dB below that at far left:
The CPU-load bar shows the CPU usage as calculated by the Jack Audio Server:
* The green segment covers the range -50dBFS to -10dBFS.
* The yellow segment covers the range -10dBFS to -3dBFS.
* The red segment covers the range -3dBFS to 0dBFS.
There are independent meters for left and right channels which monitor the system output, i.e. the mix of audio that feeds the Zynthian output. Level decays with a logarithmic rule, taking one second to decay to -200dBFS so will decay to -50dBFS (the displayed range) in about quarter of a second. Peaks are displayed instantly, i.e. the attack of the meter is immediate(*). The peak hold bar remains for two seconds or until a higher peak is reached.
(*) Meter is updated 5 times per second so there can be 200 ms delay in peak being displayed.
Alternately, CPU-load bar can be enabled from webconf, replacing the Audio Peak-meter. The CPU-load bar shows the CPU usage as calculated by the Jack Audio Server:
This is a running average of the time it takes to execute a full process cycle for all clients as a percentage of the real time available per cycle determined by the buffer size and sample rate.
This is a running average of the time it takes to execute a full process cycle for all clients as a percentage of the real time available per cycle determined by the buffer size and sample rate.
The green M flag is shown when MIDI messages pass thru the MIDI router. Not all messages are detected. Only CC, Program Change and Note On/Off.
The blue M flag is shown when MIDI messages pass thru the MIDI router. Not all messages are detected. Only CC, Program Change and Note On/Off.
The red X flag is shown when there are Xruns. You should hear clicks and pops too ;-)
The red "warning" flag is shown when there are Xruns. You should hear clicks and pops too.
When the red V or T flag is shown, your zynthian is working in a degraded state, with the CPU frequency capped to 600-800 MHz, trying to stabilize the system and avoid a system crash. You shouldn't see any of them and if you do so, you should consider looking for a better power source (under-voltage) or using a heat sink (over-temperature).

A layer is an '''Audio Processing Chain''', normally assigned to a MIDI channel, that can be composed of one or several Audio Processing Units. This units are chained by default, although you can customize the audio routing. The first unit in a layer is the '''root''' and determines the layer's type:

The rest of units in a layer are usually FX units which process the audio coming from the first unit (root).
All units in a layer receive all the MIDI events coming from the assigned channel. Some special layers (MOD-UI) don't have an assigned MIDI channel and receive all MIDI channels.

Although the '''MIXER''' is shown in the layer list, it's not a real layer. This pseudo-layer allows to adjust the soundcard output/input levels and other audio-hardware related options. Technically speaking, it's a user interface for the ALSA (Audio Linux Sound Architecture) mixer.
You can configure the mixer controllers from the webconf's hardware->audio menu. Simply click the '''+''' button on the "Mixer Controls" text area.

From the Admin menu you can access to the Audio & MIDI recording tools. These simple tools allow you to record Audio & MIDI tracks easily, using the internal SD-card or an USB memory stick for storing the files.
'''WARNING!''' Using the internal SD card to store the captured files will increase the risk of corruption. You should use a USB memory stick instead.
===Recording===
1. Press "Start Recording" to start a new capture.
2. The red circle should appear in the top-right status area, indicating that a recording is going on.
3. Press "Stop Recording" for finishing the capture. The red circle will disappear and the recorded file will be added to the list. The filename is generated automatically and should be something like "jack_capture_01". The prefix "SDC" or "USB" indicates where the file is stored.
===Playing===
You can play files by simply selecting and clicking the file. The "play" symbol will be displayed in the UI status area.
For looping the file, turn on the "Loop Play" switch before playing.
'''NOTE:''' You can play a file at any moment. Recording and playing can take place simultaneously.
When playing audio, a volume control will be shown. When playing MIDI, a BPM control will be shown for adjusting the transport speed.
Recording audio & playback MIDI are transport-bond. If you stop recording audio while playing MIDI, MIDI play will stop, but MIDI playback will remain enabled, so when starting a new audio record, the MIDI playback will start again.
===Deleting===
A bold press will delete the selected file, but you will be asked to confirm the action.
===Managing recordings from your computer===
Audio & MIDI recordings can be managed from your computer by accessing the webconf's captures section. From this section you can:
* rename recordings
* delete recordings
* convert audio recordings to .ogg format
* downloading recordings to your computer
* reproduce the audio recordings in your browser. If .wav files doesn't work in your browser, try converting to ogg.
It is a good idea to rename your recordings so they can be easily identified.

On those screens you can click the '''zynthian logo''' (top-right) to emulate the "snapshot" switch, and you can go back by tapping the '''top-bar''' area.
You can change the controller values by "sliding" up/down over the widgets. (see the green arrow in the figure here) This is the same as turning the knob. If you are using a mouse, the mouse wheel also can be used for changing the controller value.

As you can see, it has sense in a SnapShot context, where a set of layers are defined. Zs3 changing is very fast, as no engine must be started.

2. In the parameter/controller area, slide with your fingernail from '''right to left'''. The tiny number, indicating the current CC assignment, should disappear or change. If the parameter is an engine-specific controlled engine, the number will disappear. If the parameter is a hardcoded MIDI-mapped parameter, then the number will change.

=CUIA: Callable UI Actions=
The Zynthian UI can be controlled remotely using a set of commands called CUIA: Callable UI Actions. These CUIA are available on several interfaces: Key Bindings, MIDI, OSC, etc.
==Key Bindings: Controlling the UI with a computer keyboard==
The user interface may be driven using a USB keyboard, e.g. QWERTY, Dvorak, etc.

==Controlling the UI with MIDI messages==
These actions are available using MIDI messages on the Master Channel (default 16, but configurable with the webconf tool), specifically, note-on messages (0x9) are used so you can use a MIDI keyboard for controlling the Zynthian UI. For instance, to Power Off the zynthian, you send this message:
0x9F (Channel 16 Note ON)
0x00 (Note code for POWER_OFF as below)
0x00 (Velocity/parameter)
or play the C-1 key, if your keyboard has it.
This is the full list:
