To access the sequencer, select '''Sequencer''' from the main menu or long press LAYER encoder. The first time you access the sequencer you will see a 4 x 4 grid of rectangles organised as 4 columns of colours. This view is called ZynPad and provides a live performance interface to ZynSeq. Each rectangle represents a pad which may be used to play a sequence. This operation is similar to clip launchers in many DAWs (e.g. Ableton) and on hardware devices (Akai APC and Novation Launchpad devices). Use of ZynPad is described later but first there are some terms that will help understand the structure of ZynSeq.

An event represents a MIDI command, e.g. Note-on. It may have parameters such as velocity, duration, etc.

'''Pattern'''<br>

'''Pattern'''<br>

A pattern is a collection of MIDI events, e.g. notes. Each pattern has a duration in steps and may include as many simultaneous (polyphonic) notes as desired on each step. We will see how patterns are manipulated in the [[#Pattern Editor | Pattern Editor section]]

A pattern contiains zero or more events. Each pattern has a duration in steps and may include as many simultaneous (polyphonic) notes as desired on each step. We will see how patterns are manipulated in the [[#Pattern Editor | Pattern Editor section]]

'''Track'''<br>

'''Track'''<br>

A track contains a pattern or collection of patterns which may be played and looped. Each track plays out to its own MIDI channel. We will see how sequences and tracks are manipulated in the [[#Arranger | Arranger section]].

'''Sequence'''<br>

'''Sequence'''<br>

A sequence contains a track or collection of tracks which play in unison. By default each sequence has a single track.  

A sequence contains one or more tracks which play in unison. By default each sequence has a single track.  

'''Group''' <br>

'''Group''' <br>

A sequence is a member of a group (indicated by its pad colour). Several sequences may be played simultaneously but those in the same group do not play concurrently.

====Pad Layout====

====Pad Layout====

Each pad displays information split into an upper and lower part. The top part shows the current loop setting (loop all - [[#Sequence_Modes | see Sequence Modes]]), the midi channel of the track it will play on and the sequence identifier (A1). Currently the track uses midi channel 1 which is assigned the 'Poly Dreams' preset from the OB-xD instrument. The preset is used as the default name (it can be renamed) and shown in the lower part of the pad. This pad is currently empty, when the pad has content, a stop button icon will appear in the top right corner. When the pad has no sequence at all, it displays dark grey.
