The Panther ESxxx Series is a collection of SERGE
modules (re)designed to fit the EuroRack module
system offering the euro-rack user access to the
extensive and unique range of modules designed
by Serge Tcherepin.
The ES114 Universal Slope Generator
The ES114 USG as an oscillator
1. Patch the [END OUT] pulse to the
[TRIGGER IN] jack
2. Turn the [RISE RATE] and [FALL RATE]
knobs fully CW.
3. Patch [BIPOLAR OUT] into an audio mixer
or Output Module to monitor the output.
4. There should be a 5000 Hz triangle wave
present which can be changed to a
sawtooth wave of lower frequency by
turning down either the [RISE RATE] or
[FALL RATE] knob. The frequency and
timbre will depend upon the settings and
the shape as set by the relationship
between the Rise and Fall times.
5. Patch a control voltage from a processor
or other source into the [CV IN] jack. Note
the effect on the Rise, the Fall, and the
Rise+Fall times with the position of the
switch
6. Patch a 1.0V voltage into the [EXP CV]
jack. The USG will produce a doubling of
frequency (halving of the Rise and Fall
times)
The DSG may not track as well as the NTO's and PCO's when used as an oscillator.
Remove the patch from the END and TRIG IN jacks, and apply a control voltage from a
keyboard, Stopped Function, or Stepped Random Voltage Generator. Turn the RISE and
FALL knobs all the way up (clockwise, and apply the output to the control input of an
oscillator. The signal should be the same as the input. As the RISE and FALL knobs are
turned down, there should be a portamento or slowing Effect on the changing stepped
voltage.
