Oscillators 1 And 2 Vc Shape; Sample & Hold; Filter Slew/Unslew; Inverted/Controlled Matrix Red Pins - EMS iVCS3 User Manual

be converted to be the same as Oscillator 2. Please note that when the VCO3
is switched in 'High Range Mode', the Ramp Shape does not work anymore
with 'Phase Sync Oscillators'. Also we've noted it's a bit more CPU intensive.

Oscillators 1 and 2 VC Shape

This modification is often done with cheap Cliff 3.5mm jacks on the front
panels, but cable patching is not really in the spirit of the VCS3. The toggle
switch converts the matrix columns 'O' and 'P' (i.e. 'Output Ch. 1 and 2
Voltage Controlled') in 'Oscillator 1 Shape' and 'Oscillator 2 Shape' Voltage
Controlled. The sensitivity range is ±3V.
Sample & Hold
This modification brings a Simple Random Voltage Generator or a Sample &
Hold to the iVCS3. You can switch between S&H to generate random
numbers and hold them for a period of time and also Glide to generate a
user-controlled random number series with interpolation between each new
number. When enabled, the COLOUR parameter is the frequency with which
new random numbers are generated in the range 0.016 ÷ 10 Hz. The LEVEL
parameter is the range over which random numbers are distributed.

Filter Slew/Unslew

The novel glide parameter was introduced to enhance the sound quality of
the VCF and optimize the smoothing of the cutoff frequency control. You can
adjust and trim this parameter to get the most concise sound. We've found
that the lower the glide threshold, the better the sound when the VCF is
frequency modulated by oscillators. In other words, when high frequency
controlled voltages are applied to filter, they are low-pass filtered by the C31
capacitor. This means that the filter will not respond to high frequency CVs,
and respond slowly to rapid changes in incoming CVs. The knob parameter
sets the C31 cap from the CV input circuit, so the filter will respond to high
frequency controlled voltages.
N.B. Old parameters will set automatically to the maximum Glide amount
(left), this parameter is saved for Snapshots, HVPad and will work with
Control Manager.
Envelope Shaper Attack and Decay Time Extension
This modification will give you an attack of 5 seconds and decay of up to 3
minutes. Press the ATTACK button and play!

Inverted/Controlled Matrix Red Pins

Tap over the Recovery Pins (Matrix bottom) to change pin color: white, green
and red. White pins are 2.7K Ohm resistance and green ones are 68K Ohm.
