Analogue Solutions Cranial Saw - Manual

GLIDE Control / Switch
The rotary control sets the Glide
(portamento) time for both s. VCO
But if the Toggle switch is up, then
Glide is only applied to 2. VCO
The normal mode would be down
so Glide works on both VCOs.
Scaling for VCO1 will be a little
out when Glide for VCO1
removed since a whole circuit
gets disconnected - but this
should not be an issue since this
mode is more for sound effects.
TUNE Slider
This slider sets pitch for both
VCOs
MIX Output
This is the audio output from
the mixer. Signal sources for
the mixer are each
and VCO
the Sub Osc.
VCO VCO 1 / 2 Square Wave Outputs
These are the square ( ) audio PW
outputs from each , pre-mider. VCO
PITCH CV input
This is the main pitch CV
input. It will affect both
VCOs, and is sent pre-
Glide.
MOD CV Inputs
These input sockets allow the pitch of each to be CV VCO
modulated. The lower socket is a direct input.
The signal sent to the upper socket can be attenuated using
the slider. BOTH
SYNC
When the switch is
up
Sync is VCO
enabled. When
enabled the Detune
range is increased
to allow extremee

Power connector as found on Medic Modules
Specification;
Width: 38HP
Depth: 25mm
Weight: 285g
Voltage: -/+12V
Power Consumption: +12V, 15mA / -12V, 28mA
Doepfer style power cable included.
Screws not included.
Mounting/Connection tips;
The supplied power cable is keyed.
That means it can only be fitted one
way! (Unless you use excessive force).
Pin one is at the top on our modules
(Doepfer fit their sockets upside-
down).
Medic Modules use a 14 pin 'boxed'
header on the . PCB
The two ends of the power cable are
different. Plug the 14pin socket end
into the Module power header.
Plug the larger 16pin socket into
your case power supply.
Note: Physically disconnect your
power supply/case from the mains
electricity.
Ensure you connect up the module
correctly!
Ensure it is screwed into the case.
Ensure no metal parts can short out
the solder joints on the rear.
Ensure your case is 100% functional
before fitting the module.
It has been found over the last 15
years of making modules, that around
90% of module problems have typically
the following user problems;
Power cable connected wrong,
faulty power supply, other poor quality
modules fitted in the case affecting
other modules.
cranial saw dual vco
Cranial Saw is a dual with Sync, Sub Osc, Glide, Cross mod and more! VCO
It is based on modified old circuit designs from the mid 1970s - giving a very full and vintage
sound.
VCO VCO PW 1 / 2 Inputs
Each has a Pulse Width input, to allow VCO CV
external control over the pulse width of each
VCO's square wave.
VCO FREERUN 1
When this switch is up,
then will no longer VCO
track the input PITCH CV
socket.
PW PW 1 & 2 Sliders
These two sliders allow the
pulse width of each
's VCO
square wave to be manually
set.
DETUNE Slider
This slider is used to
detune
2 relative to VCO
VCO1.
SUB OSC Output
This is the audio output from
the Sub Osc, pre-mixer.
WAVE Switches
The position of these swiches
determines whether each
VCO's saw or square wave is
sent to the mixer.
VCO2 Mod Slider
This slider is used to
attenuate the
signal CV
patched to the VCO CV 2
socket below.
VCO VCO SUB 1 / 2 / Sliders
These sliders set the level of
the above audio sources that
are sent to the mixer.
