ASHIKO is a quad stereo VCA designed to create multi-directional sounds starting with mono sources.
• To instantly create a stereo image with a mono source and a single CV input.
• To CV switch a sequence and send it alternatively to two different oscillators.
• To direct the movements in a quadrophonic system.
• To control up to 4 sources with independent CVs and send them to 8 different outputs.
• LFOs perfect as CV inputs. –
• Oscillators enhance them in the stereo field. –to
• Delays instant ping-pong effect. –
• Samples manipulate their presence in the mix with addition modulations. –
Plug an input into “I” and a LFO in “V” onnect the two outputs “O” into a mixer / output module. . C
The switch at the bottom is used to set the mono – stereo mode of the VCA. The other toggle is to select between
a hard and a soft pan curve. Visual feedback of which of the two output is currently open is given with two blue
“It’s called see-saw VCA because when an output is linearly opening the other one is alternately closing
following the behaviour of the CV source. Different kind of controls pulses, envelopes, complex waves - –
will make the VCA react in a distinctive way .”
With stereo mode active bottom toggle switch on - connect a triangle wave from LFO in the V input. Rise –an
the frequency of the LFO to speed up the opening-closing action of the VCAs, resulting in a faster stereo and
phasing effect. Make this panning harder or softer with the other toggle switch.
Experiment with all kind of input waves get unique results. to
• 4 Stereo full range VCAs.
• Transistors based CV inputs designed to give the best results with LFOs.
• Individual toggle switches to activate mono or stereo mode.
• Selectable hard/soft switching curve.
• Input and CV are normalled and they flow top to bottom when no jack is inserted.
• Works with audio and CV sources.
• “ hatever” don’t W power connector a.k.a. mind the polarity.
• current draw +12V 85ma, - 70 12V ma
• dimensions width 6HP, depth mm 25
