Sequencer; Time Signature - KETRON SD1 User Manual

Sequencer

The internal sequencer of the instrument allows the user to create or modify midi sequences in a rapid and functional manner, being provided
with advanced functions that are typical only to sophisticated computer programs. Press the SEQUENCER button to access the main page. Note.
All operations performed on the sequencer must always be saved on disk (see LOAD/SAVE) before exiting the menu or turning the keyboard off.
Otherwise, the recorded data will be lost forever. When in the Sequencer mode, the first track out of the 16 available is selected. All the tracks
are empty, including the MASTER TRACK. The various functions can be accessed from the main page.
NAME:
Use the Cursor<> buttons to access this box and give a new name to the sequence ("SEQUENCE" by default). Press the
Save/Name button: an edit window will appear, bearing the current name of the sequence. Every letter that is highligh-
ted by the blinking cursor can be changed by typing on the keyboard. Each key corresponds to a letter that is clearly
marked in the serigraphy on the ketyboard. After each letter entry from the keyboard, the cursor automatically moves
forward by one letter (you may enter up to 8 letters). As an alternative to the keyboard, the Value-/+ buttons may be
used. In this case the cursor will not move forward automatically. If the Value-/+ buttons are pressed together, all edi-
ted letters, starting from the current cursor position, will be cancelled. The Cursor<> buttons can be used to move the
cursor from one letter to another. Press F10 (Execute) to confirm the new name, press F5 (Escape) to cancel editing.
TEMPO: It is the speed, expressed in quarters per minute, with which the sequence will be played once it has been recorded. The
tempo default value is the one of the last style selected. Use the Cursor <> buttons to access the TEMPO box and chan-
ge the tempo value by pressing the Value-/+ buttons. When the recording starts, the tempo is memorized in the MASTER
TRACK. During recording, use the Fast/Slow buttons to register any tempo variations on the MASTER TRACK. Tempo
events can be entered, modified and cancelled after recording, by using the MASTER TRACK menu functions as explai-
ned below.

TIME SIGNATURE:

It is the bar musical division. The default value is 4/4, i.e. each bar is divided into four quarters. Use the Cursor <> but-
tons to access the SIGN box and change the numerator/denominator values by pressing the Value-/+ buttons. When the
recording starts, the SIGNATURE is memorized on the MASTER TRACK. As with tempo, the SIGNATURE can be entered,
modified and cancelled by using the MASTER TRACK menu.
POSITION: It indicates the current position of the sequence. It is divided into three areas that can be accessed by means of the
Cursor<> buttons or by pressing the F1 button in succession. The first value indicates the bars, the second value indica-
tes the quarters, the third value indicates the steps making up one quarter. Each quarter is made up of 48 steps. Once
the position has been selected, its default value [1 1 1] can be changed by pressing the Value -/+ buttons. Pressing the
Value -/+ buttons together will reset the default value.
TRACKS: The sequencer is divided into sixteen tracks, plus one MASTER TRACK. Track names are given in the center of the page,
preceded by a progressive number. Track default name is "TRACK_n". Single track names can be changed by means of
the OPTIONS menu described hereafter. Recording is performed on the highlighted track; therefore, the track on which
one wants to record must be selected before recording begins. Tracks are selected by pressing the Page<> buttons. The
display will show only the group of tracks from 01 to 08 or the group from 09 to 16. Therefore, every time you scroll the
tracks, passing from track 08 to 09 by pressing Page> or from 09 to 08 by pressing Page<, the display is updated with
the new group of tracks. Tracks can be selected also by using the Cursor <> buttons, but in this case you must pass throu-
gh the field [Chan.] reserved for playback midi channels. In any case, even if the midi channel field stays highlighted,
the selected running track is the one on the left-hand side of the highlighted area.
CHAN: The playback midi channel is shown on the right-hand side of each track name. Use the Cursor <> buttons to access the
channel box and the Value -/+ buttons to change the playback channel. By default, the channel is set on [All]; this means
that when playing back, the midi channels will be reproduced on the originally recorded channels. Instead, by selecting
values from 1 to 16, all the midi events recorded on the related track will play on the selected channel. For example,
events belonging to the same midi channel can be recorded on different tracks (for example, by playing on the right-
hand side of the keyboard), and different midi playback channels can later be set for each recorded track.
