"This is not to unveil and explain the mysteries of this module. It is still a bit of an enigma to me. This is only to give a very little idea of what can do this module.
The patch is this one : The two LFO1 of the two Dark Energy delivers two low-frequency signals that modulate the A-136 through an A-133 (in order to attenuate and control the two low-frequency signals before they reach to the Ext.Level of the A-136). An A-110 delivers a sawtooth audio signal that is waveshaped by the A-136 and the result is send to the Ext.Audio input of one the two Dark Energy.

Thanks for watching and listening. Wishing to be somewhat helpful..."

"SpheroSampler is a unique sampler that records and plays audio using two touch controlled 3D spheres. It has a simple but effective synth that is played using an XY pad, and also records through the mic. You can also use an adapter to plug in a mic or even your guitar. I really like the whole concept of this app, especially the way you can record and play back at any speed, both forward and reverse. You can create variation in the speed, and constantly direct the play head to new places on the recording. This is a free app, with a $0.99 in-app purchase for saving and exporting recorded and mixed wav files through iTunes. At first I was disappointed that only iTunes exporting was offered, but soon heard back from the developer that Audio Copy & Paste will be supported in the next update. I've really enjoyed using this app and love the endless creative possibilities it offers. It's great to see new concepts for sampling like this, and with Audio Copy & Paste coming soon, I have to rate this ... A Killer App!
Review by Nick Trass"

"SpheroSampler is new-generation music instrument which records and plays audio tracks onto two 3D-spheres.

It is new idea for sound making. Using SpheroSmpler, you will obtain new surprising sounds and loops.

Playing SpheroSampler is resemble dj and violin-player work. You vary speed and do smooth morphing of sounds, for making new unique music!

You can record your sounds via microphone or using build-in synth.
Also, you can export your mixes into wav-files.

We love spheromusic. And hope you will too."

"Quadrature Oscillator (QUO)

The QUADRATURE OSCILLATOR (QUO) provides signals and features which make it ideal for controlling the Quad Panner . It generates two sine waves which are always displaced 90 degrees in phase from one another . This phase difference provides exactly the correct relationship for swirling a sound through quadraphonic space in a circular pattern (using the Quad Panner) . Since the Oscillator has a basic range from longer than 20 seconds per cycle to 500cycles per second, many effects can be produced . Swirling a sound at an audio rate produces interesting spatial and modulative effects. Additional features include linear VCA's for each of the outputs. so that spatial swirls can be made to decrease in size, effectively spiralling inward . A HOLD input"freezes" the outputs whenever pulsed high . Thus a swirl can be stopped at a given location, with the sound just "hanging there"until operation is resumed . Switches on the Panel allow disabling the oscillator, a feature which has been found to be useful for live performance .The use of this module is not limited to Quad Panning . The phase separation between the oscillator's outputs provides for many interesting cross-fading effects when they are used to control other Serge modules.

Dual Transient Generator (DTG)

The DUAL TRANSIENT GENERATOR (DTG) provides two independent outputs with voltage controllable rise and fall times. This module is identical to the Dual Universal Slope Generator except that it does not have all of the front panel features. This module is a useful, space-effective unit to be used for many of the same functions as the Dual Universal Slope Generator. Common uses of the Dual Transient Generator are for simple "AR"-type envelope generation, as a dual voltage-controlled low frequency oscillator, or as a voltage-controlled clock (especially suitable for clocking the Touch Keyboard Sequencer or any of the Sequencer Programmers). These functions can be patched with the Dual Universal Slope Generator, but since many of the features are left unused in these patches, the Dual Transient Generator provides the same function while using less front Panel space.

"VCTimeGen Clock (TGC)

The VC TimeGen Clock has the left cell "blue" out being an asymmetrical tri wave & "red"out being a 50% duty cycle square wave output which stays constant through the manual "freq' POT range in combination with the "both" position selected w/ external CV -- BUT with the ability to modify the duty cycle (pulsewidth) of the output(s) using external CV source from either the front or the back ofthe pulse by selecting "rise" or "fall" on the CV source select switch. That way you can create syncopation in the rhythm patches & pulse width mod in the audio range use.

The right cell has DTG functionality, just like the CV TimeGen OSC.

÷N Comparator (NCOM)

The ÷ N COMPARATOR (NCOM) consists of two sections: a comparator and a voltage-controlled pulse divider. The divider section outputs a pulse once every "N" comparator pulse, where "N" is a number from 1 to 31, settable with a control voltageat the divider's VC input (or manually via the divider's control knob). Additionally, the Divider outputs a staircase wave with "N" steps.This will produce whole-tone steps when plugged into the 1 V/Oct input of aVCO.

This module has two distinct areas of use (in addition to the normal functions of the comparator):

For audio frequencies, the divider can be set to output sub-divided frequencies with digital precision. Output frequency depends on "N". If "N"= 2, 3, 4, etc., the output frequencies will be an octave, an octave and a fifth. or two octaves below the input, respectively. Because "N"is voltage controllable, arpeggios and various melodies can easily be programmed. The nature of this type of division (integer division), results in frequencies that fall along the sub-harmonic series, a series that has great tonal charm.
For sub-audio frequencies, the divider acts like a counter, outputting a pulse only after "N" number of input pulses. Input pulses can be fairly random, or regular. This capability is especially powerful for determining tempos and rhythmic patterns when using several sequencers (especially if the "N" vc input is taken from one of a sequencers rows of controls). In a more random situation, using a microphone preamp/detector as input. the divider might be set to count how many times a sound of a certain loudness will have occurred, and be set to trigger an event upon reaching the count. Since the count can be made variable (from 1 to 31), fairly complex and subtle inter-actions can be generated.
Wizardry: With feedback, this can be patch-programmed to oscillate.You can vary the frequency by turning the divider control knob. Using this module to divide clock pulses is an obvious application; it is also useful for dividing high-frequency audio.

DualAnalog Shift Register w/ input attenuator pot (2ASR)

The ANALOG SHIFT REGISTER (ASR) is a sequential sample and hold module for producing arabesque-like forms in musicalspace (see diagram). Whenever pulsed, the previously held voltage is sent down the line to three consecutive outputs to produce the electrical equivalent of a canonical musical structure. A pulse output permits linking two or more Analog Shift Registers together to form longer patterns.

Quantizer(QUAN)
The QUANTIZER (QUAN) provides a simple means to turn any control voltage into voltage steps corresponding to well tuned (equal - tempered) tones of the musical scale. It is scaled to 1volt per octave. Thus, a zero to +5 volt envelope at the Quantizer's input produces a staircase of voltages corresponding to a chromatic scale spanningfive octaves.

If patched to the 1 volt per octave input of an oscillator tuned to "E", a gradual slope of 1 volt applied to the input of the Quantizer will produce the following steps of the musical scales:
E - F - F# - G - G# - A - A# - B - C - C# - D - D# - E. (normal chromaticscale)

If the 1/6 Scale Select is HIGH, then the scale produced will be:
E - F# - G# - A# - C - D - E. (whole - tone scale)

If the 1/3 Scale select is HIGH, then the scale produced will be:
E - G# - C - E. (scale of major third steps)

If both the 1/6 and 1/3 inputs are high, the scale will be:
E - F - G# - A - C - C# - E. (alternating half - step/minor third step)

Since the Scale Select inputs can be activated very quickly, the Quantizer can produce a very wide variety of tonal effects, quickly moving between four different types of musical scales(chromatic, whole - tone, the augmented triad, and a six - step major - minor scale often heard in certain oriental musics).

The Quantizer features six channels, as a "stand - alone" module, and takes up two inches of panel space. Accuracy of the Quantizer is 3 cents maximum deviation from the ideal equal -tempered semi - tone over a five octave range (i.e. just about the limits ofpitch sensitivity of the human ear). Response time for all channels is about 8 milliseconds."

Dual Comparator (COM)
The DUAL COMPARATOR (COM) provides several often useful house-keeping functions within the Serge system:

Logical Decisions: If the + input is greater than the - input, then the output will be high. If not, then the output will be low.
Level Detection. A pulse will be generated whenever an input voltage reaches a pre-set threshold. For example, when an envelope detector reaches a certain loudness level, it can be used with the Comparator to generate a pulse to activate or de-activate other events programmed within the synthesizer.

Voltage variable pulse width modulation of any of the Serge oscillators.
"Squaring" audio signals, whereby frequency related pulses are derived from an input signal. These pulses can be used for frequency sub-division (via a Dual Slope Generator or Sequencer), or as raw audio, rich in harmonic content.
In addition to the +/- inputs, eachof the Comparators include a front-panel knob to manually set a threshold.

"Audio Mixer w/ phase switch (3x1) (AMX)

The Audio Mixer is a three-in/one-out manual mixer with a phase switch on input 3.

Variable Q VCF (VCFQ)
The VARIABLE Q VCF (VCFQ) is an excellent general-purpose VCF offering simultaneous low-pass, high-pass, band-pass and notch (band-reject) outputs.The resonance (Q) of this filter is dynamically variable by manual or voltage control. The VCF Q has two signal inputs. One incorporates an automatic gain control to prevent the filter from overloading at high Q settings. The second input has a level control so that the percussive effects of overloading the filter can be exploited. When a pulse is applied to the Trigger input, the filter will ring, producing a damped waveform similar to that produced by striking a resonant object. The nature of this ringing is controlled by the Q and the filter frequency. Percussive effects ranging from clicks to the soundof wood blocks and bell tones can be produced and controlled. This ringing effect can be used in conjunction with signals applied to either of the audio inputs to achieve highly controlled complex tonal qualities.

Other comments:
A nice bit of flexibility is the "LO" setting that turns it into a CV processor! ... Recent updates to the filter's circuitry are noticeable as well- Its much easier to get tube-type harmonic warmth just by nudging the gain control. The feedback and overdrive characteristics have also been tweaked to be more musically useful... This filter will not oscillate unless you patch it up for feedback... Hi-Lo range switch for fantastic and unique audio/cv applications - hit it with a pulse, get an unbelievably slow damped sine wave.Calibrated 1 v/oct and attenuated cv inputs, just like the oscillators... Since it's a multi-mode filter, it's 12 dB/oct roll-off. You may want a LPF with more 'bite' in some applications. I think the bandpass and all pass sections of this filter have 6 dB/oct roll-off.
