Selecting a Sequence
The 3650 has 7 sequence memories available. If the entire row of white keys is lit or flickering, you are in
SEQUENCE mode. The steady LED indicates the currently selected sequence. Whichever sequence you have
selected is the one you are modifying when you enter PROGRAM mode (steady STEP LED. The selected
sequence will play to the end then loop back to the beginning.
To select a different sequence, press the white note key corresponding to the sequence you want to select. If
the sequencer is running, the newly selected sequence LED will flash until the sequencer reaches the end of the
current sequence (or on the next clock; see CHANGE ON CLOCK mode), and will then switch to the new
sequence.
Another way to select a sequence, even while the display is in another mode, is to hold down the RESET/PROG
button then press the desired sequence button. The display will automatically change to SONG/SEQUENCE
SELECT mode.
Selecting a Song
The 3650 has 5 song memories available, which can be used to string together up to 16 sequences in any
order. If the entire row of black keys is lit or flickering, you are in SONG mode. The steady LED indicates the
currently selected song.
Each song step contains one sequence. When running and the current sequence has completed, the sequencer
will advance to the next song step and play the sequence it contains.
To select a song (and switch to SONG mode), press the black note key that corresponds to the song you want to
play. If the sequencer is running, the newly selected song LED will flash until the sequencer reaches the end of
all the sequences in the current song (or on the next clock; see CHANGE ON CLOCK mode), then it will switch to
the new song.
Another way to select a song, even while the display is in another mode, is to hold down the PROG/RESET
button then press the desired song button. The display will automatically change to SONG/SEQUENCE SELECT
mode.
Programming a Song
Each step in a song contains a sequence. To program sequences into song steps, first make sure the keyboard
display is in SONG/SEQUENCE SELECT mode (press OCTAVE UP and OCTAVE DOWN at the same time if it’s
not). Press one of the black keys to select the song you want to work on.
