1.Control Voltage - This is a 0 to 6V CV output to
be used with 1v/oct calibrated oscillators and
VCFs.
2.Trigger - This is a short timing pulse that is sent
out at the start of every new note. It's range is 0 to
5V
3.Gate - This is a timing pulse that is sent out for
the duration of a note's length.
4.End of Sequence - This is a timing pulse sent
out on the last note of a sequence.
C.Sample Patches
For the first two sound samples, the
diagram on the right shows the patch used. A
clock is being input to the Auto-Seq. The Auto
Seq's trigger and gate outs are being sent to
Envelope Generators, which are then being sent to
control the cutoff frequence of a VCF and the
amplitude of a VCA. The Voltage output is being
sent to a VCO and VCF. The VCO's output is
being sent to the VCF, whose output is being sent
to the VCA. For the third sound sample, this same
patch is used, but the clock is also controlling a
pair of drum sounds.
Listen to example 1 here. This mp3 just demonstrates a few different sequences being created by
hitting the "New Sequence" button. No other controls are manipulated.
Listen to example 2 here. This mp3 demonstartes all of the knobs being manipulated. First is the
musical mode knob, then length, then rhythm subdivision and finally pitch range.
Listen to example 3 here. In this mp3 the Auto seq is paired with a pair of drum sounds to help give
context to it's rhythmic changes. The straight rhythm switch, rhythm knob, range knob and the new
button are all manipulated in this mp3.
