It is possible to use a MIDI controller to add notes to a pattern, e.g. MIDI keyboard connected to Zynthian. Select "Input channel" from Pattern Editor menu to adjust the MIDI channel that ZynSeq listens for input. When the Pattern Editor is shown, any note sent on this channel will add a note to the pattern at the current playhead cursor position with the a duration of one step and if the pattern is not being played, move the playhead to the next step. To add longer notes press the sustain pedal whilst adding notes. Each press of a note whilst the sustain pedal is pressed will extend the note by one step. The playhead does not advance until the sustain pedal is released so chords may also be added whilst the sustain pedal is pressed. The playhead may be advanced without adding any note by pressing and releasing the sustain pedal. It is also possible to assign a note that acts as a rest, i.e. will not add a note to the sequence and skip to the next step. Select "Rest note" from pattern editor menu to select which note will act as a rest. None may be selected by rotating SELECT encoder to the end of the range, i.e. below C-1 or above G9.
