I.Using The Module
A. What is Auto-Seq?
"Auto-Seq" is shorthand for "Automated Sequencer." It is a unique step sequencer hich
programs it's o n sequences. There is a small selection of controls to help refine it's sequences to
the taste of the composer. There is no ay of storing and recalling the sequences hich it rites,
Auto-Seq is an improviser. If you're interested in random composition, or if you're just tired of the
hand cramps that come ith programming traditional step sequencers, then this is a module that
you might find useful.
B. Controls/In uts/Out uts
Controls
1. Mode - The Auto-Seq has a built in quantizer, this knob selects hat musical mode it ill
quantize to. From least clock ise knob position to most clock ise, the modes are Major, Minor,
Major Pentatonic, Minor Pentatonic, Fifths and Chromatic.
2.Length - This knob controls the length of the sequence. This is measured by the number of input
clock pulses before the sequence resets itself. The range of pulses before reset is 1 to 256.
3.Rhythm Subdivision - The input clock pulses are run into a 4x clock multiplier and then through
a divider. This control selects hat division of output is used by the sequencer for functions other
than Length. The range is from 4x input to 1/8 input. This knob is only read at the start of a ne
sequence.
4.Range - This selects the range of pitches that Auto-Seq can output. It selects by octave, ranging
from one to five octaves. When the sequencer is choosing notes, it ill check to see if a note is in
range, and if not it transposes the note do n an octave. So hen increasing range, you ill hear
the same notes, just in different octaves.
5.The "One" Switch - When activated this s itch ill make sure that a note is played on the first
note of the sequence (the "one" of the sequence) and that the note ill be the root note of the scale
being played (the "one" of the scale).
6.Portamento - This s itch ill turn on portamento or glide bet een notes. Not all notes ill be
played ith portamento. The effect becomes more noticable as the range of pitches is increased.
7.Keychange - This s itch sets hether or not the next sequence to be ritten ill be in a ne key.
When this s itch is disengaged, all sequences ill be in the key of 0V as their root note.
8.Straight Rhythm - This s itch, hen engaged, sets the sequencer to play a note on every beat.
There ill be a minor variation on the note length from the gate output. This s itch is only read at
the start of a ne sequence.
9.New Sequence - This pushbutton tells the sequencer to rite a ne sequence. The ne sequence
ill be played hen the current sequence finishes.
In uts
1.Clock - A series of timing pulses should be input here.
2.Reset - This tells the sequencer to play the first note of the sequence on the next incoming clock
pulse. It's used to help syncronize ith other timing devices.
3.New - This input has the same effect as the Ne Sequence button, but can be activated by a gate
or trigger.
