First we need to understand some user interface elements. ZynSeq includes a menu that is shown by short press LAYER or touching the top left of the screen. The LAYER or SELECT encoder may be used to highlight entries within this menu and short press LAYER or SELECT will select that entry. Alternatively the touchscreen may be used to select an entry by touching the selection. If the menu extends beyond the bottom of the screen it may be scrolled by highlighting lower entries with the SELECT or LAYER encoder or press and drag with the touchscreen. (Note: When touch and dragging on touchscreen the menu option will be selected when touch is released.) The first entries in menu are common to all ZynSeq views. Entries below the first divider are sensitive, i.e. specific to the current view or action being performed. The topbar shows a button that may be clicked to exit the current view.

Short press BACK to touch the topbar to close the menu without selecting an option.

If a parameter is selected from the menu its title and value is displayed in the title bar at the top of the screen. This is called the ''parameter editor''. The value may be adjusted with the LAYER or SELECT encoder or fine adjusted (if appropriate) with the SNAPSHOT encoder. The value is asserted by a short press of LAYER or SELECT. Bold press SELECT may reset value to a default. Short press BACK to cancel out of the parameter editor. If touchscreen widgets is enabled then buttons appear in the title bar allowing adjustment of the parameter.

By default each pad triggers a sequence containing a single pattern. Bold press SELECT encoder to show the Pattern Editor for the highlighted pad or press and hold the pad on the touchscreen. There is a grid on the right called the ''Step Grid''. On the left is a representation of a piano keyboard, scale or drum map. Each row represents a note and each column in the step grid represents a step in the sequence.

Step sequences are a quantised collection of events, i.e. each event occurs at a discrete time and the available discrete times are equally and evenly distributed across the pattern. This means the difference in time between step 1 and step 2 occurring is the same as the difference in time between step 2 and step 3 occurring.

One of the cells in the step grid has a coloured outline. This is the ''cursor'' and identifies which cell is currently highlighted. Rotate the BACK encoder to move the cursor up and down (between notes) and the SELECT encoder to move the cursor left and right (between steps). To add a note, move the cursor to the desired step and note then short press the SELECT encoder. A note may be removed in the same way. Alternatively press the touchscreen on the cell you want to add or remove a note. Press and drag to allow more accurate positioning. As a note is added it is also sounded (MIDI sent to engine). All steps in a pattern are always shown, i.e. there is no horizontal scrolling or zoom. Notes above or below the visible area may be accessed by moving the cursor beyond the view with the BACK encoder. The view scrolls as the cursor reaches the edge. Alternatively use the touchscreen to press on the keyboard and drag up and down to vertically scroll the view. Note that as you touch a key on the keyboard it plays that note briefly. This is a useful tool for auditioning notes or phrases before adding them to the step grid.

To preview a pattern, short press the SNAPSHOT button to start the transport. A coloured bar at the bottom of the view will move left to right to indicate the position of the playhead and any notes entered in the pattern will be sent to the Zynthian's engines. To pause playback, short press SNAPSHOT. To stop and recue to the start of the pattern, bold press SNAPSHOT. If touchscreen widgets are enabled, pressing the touchscreen at the top right corner will display the transport controls. Pressing the right pointing arrow play button will start playback. The play button changes colour to indicate it is playing. Pressing again will pause playback. Pressing the square stop button will stop playback and recue to start of pattern. Pressing top right of screen will hide the transport. Playback speed (Tempo) can be adjusted with the SNAPSHOT encoder or by selecting "Tempo" from the menu.

The MIDI channel used by the Pattern Editor will be chosen from the sequence / track from which it is launched, e.g. if you selected the first pad (without changing default settings) it should play on MIDI channel 1.
