OVERVIEW
OPTOMIX
is a two-channel
Low Pass Gate
that utilizes 4 vactrols in order to provide simultaneousvoltage-control over the
Amplitude and Frequency content of a signal. It is in essence, a VCF-A (Voltage
OPTOMIXSUM
ming stage, complete with an
AUX
iliary INput allowing for the chaining of multiple units to create larger mixes (this also works well in combination with the
modDemix).
The new
OPTOMIX
has the same sound and original feature set, save for one Normalization: CHannel 1 Signal OUTput is no
longer Normalled to the CHannel 2 Signal INput. What we have added is the ability to allow
OPTOMIX
to be used as an Audio
Compressor or CV Processor/Generator.
The
DAMP
parameter, unique to
OPTOMIX
, allows the artist to ProGraM the way the
Low Pass Gate
responds to a decaying
control transient, such as an Envelope signal generated by MATHS or a Gateapplied to a CHannel’s
STRIKE
INput (see below).
DAMP
is continuously-variable, allowing anything from a long, slow, ringing to a short, fast, and muted response.
The
STRIKE
INput allows the artist to use a typical 8V Gate signal to trigger the
LPG
(Low Pass Gate) circuit by “plucking” or
“striking” the vactrol, thus allowing it to impart its magically-slow response time to the Amplitude of the signal being processed
(this concept is also featured on the Make Noise DPO, MMG, LxD, and RxMx). Combined with the
DAMP
parameter,
STRIKE
allows for the programming of percussive sounds(i.e. sharp Attack with Voltage-Controlled Decay) without the need for a
Voltage-Controlled Envelope Generator.
As a
VCA
,
OPTOMIX
has a moderate Attack response and slow Decay response, meaning that it turns onsound that is dynami-
cally processed. Folks have often described the sound as “ringing,” and while the circuit is not technically ringing, that does
describe many of the sounds possible when using a
LPG
such as the
OPTOMIX
in order to process complex signals generated
through FM or Ring Modulation.
As a
VCF
, it is a mild, non-resonant
Low Pass
circuit acting to gently reveal (or hide) the sharper edges of asimultaneous loss in
high frequency content that is similar to the natural loss of energy in idio and membranophonic instruments.
PERSPECTIVE
OPTOMIX
, being a vactrol-based circuit, will never have the speed or tight tolerances found in many other
VCA
and
VCF
circuits.
I would recommend that musicians desiring closely matched gain across multiplechannels of
VCA
s look elsewhere! If you seek
to ProGraM extremely short sounds, clicks, pops and ticks,
OPTOMIX
is not the best choice. What
OPTOMIX
smooth, natural
sounding circuit.
