VI.2. USING THE POSITION GATE SWITCHES
Set the SKIP/OFF/RESET switch to SKIP. Move various
GATE ASSIGN switches to the lowest position and notice
how the rhythmic and melodic effect of the sequence chan-
ges as you skip different notes of the sequence. By elimina-
ting all the major thirds from the sequence, for instance, you
can change the modality of the sequence so that it can be
considered either major or minor. When you have finished
experimenting with the SKIP function, change to RESET and
observe the effect of the sequence when it is shortened. Noti-
ce, for instance, that by resetting after 3 steps (GATE ASSIGN
switch 4 down) you create triplets. By raising switch 4 and
lowering 5, you change to a 4/4 rhythm.
When you have finished experimenting with the RESET
function, change the SEQUENTIAL/RANDOM switch to RAN-
DOM. You will now be hearing the same 16 notes, but in ran-
dom order. Change to the SKIP function and you can elimi-
nate any notes from the sequence using the GATE ASSIGN
switches.
VI.3. CLOCK FM
As you will recall from earlier discussions, the CLOCK
in the sequencer is actually a VCO similar to the VCOs in
your synthesizer. It is designed, however, to operate only at
subaudio frequencies. The CLOCK FM input on the sequencer
works in much the same way as the FM inputs on the VCO
in your synthesizer. The CLOCK FM input on your sequen-
cer is normally connected through the jack to the output of
GATE BUS 1. The output of GATE BUS 1 will be 11either zero
volts or +10 volts, depending on whether the GATE ASSIGN
switch for each position is set to GATE BUS 1 or not. In other
words, if the sequencer is in position one and the GATE AS-
SIGN switch for position one is up, then a +10 volt signal will
appear on GATE BUS 1. If the GATE ASSIGN switch is in any
other position, then GATE BUS 1 will show zero volts.
Start with all the GATE ASSIGN switches in the middle
position. Raise the CLOCK FM slide attenuator half-way up.
Start the CLOCK and set the CLOCK FREQ for a fairly slow
tempo. Move the first four GATE ASSIGN switches up to
GATE BUS 1. Notice that the sequencer steps through those
positions about twice as fast as through the others. Try to
adjust the CLOCK FM slider so that the first four positions
are exactly twice as fast as the others. Then move different
combinations of GATE ASSIGN switches to the GATE BUS 1
position to get different rhythmic effects.
Using the method described above, try modifying the se-
quence you have tuned to create the following rhythm:
