AUDIO PLAYGROUND'S ARCHIVES OBERHEIM PAGES
The Oberheim Mini-Sequencer is a quantized dual
output, eight position analog sequencer
with sample & hold and voltage controlled clock. Eight dual
concentric pots are provided
for generating two separate control voltage sequences These two
outputs can be used to
drive two separate synthesizer voices to obtain two melodic lines,
or one of the control
voltage outputs can be used to drive the voltage controlled clock,
in order to generate a
desired rhythm. A rotary switch is provided for setting the sequence
length from one up
to eight steps, and each sequence position is indicated by an
LED indicator.
A sample & hold circuit is an integral part of the Mini-Sequencer.
This circuit samples an
internal noise source and produces a random control voltage sequence.
The sample rate is
detetmined by the voltage controlled clock.
The range which the random samples cover can be controlled by
the Range pot and a Lag
pot is provided to produce a portamento effect between samples.
The noise generator output
is available as an audio signal source.
The voltage controlled clock controls both the sequence rate and
the sample & hold rate. This rate is
controllable over a range of from one clock every 10 seconds to
40 clocks per second. either by front
panel control or by means of a control voltage. A "Run-Stop-Step"
switch is provided to allow
the sequence action to be started. stopped. or stepped through
one position (or one random sample)
at a time.
The Mini-Sequencer is packaged as a module one-half the size of
the Synthesizer Expander Module
(panel size ol 4 1/2" x 7 1/2"). It weighs 3 Ibs.
