Modulo Magic by Ken Stone , page dedicated to this circuit is here : http://www.cgs.synth.net/modules/cgs40_modulo_magic.html ,description given by Ken on the site :


A CV and signal processor based on the mathematical modulo principle

In the mathematical world, modulo gives the remainder after an integer division. For example 7 divided by 4 would give a result of 1, with 3 remainder, so 7 modulo 4 would be 3. 11 modulo 4 would also be 3, as would 15 modulo 4 and so on.

This module allows a similar principle to be applied to a voltage. If the modulo (Step Initiation CV) is set at 1 volt and the step size also set at 1V, the output would follow the input while the input remained between 0V and 1V. As soon as 1V was reached, 1 volt would be subtracted from the output, so for an input varying between 1V and 2V, the output would track at a volt less, i.e. between 0V and 1V again. There are 8 stages to the module, so this process would occur again as the input voltage passed 2 volts and so on up to 8 volts. Of course, the Step Initiation CV and Step size are adjustable.

This can be used to constrain a CV to a single octave or similar interval as needed.

Now consider if the step size is greater than the Step Initiation CV (SICV) - each time a multiple of the SICV is passed, the greater step size voltage will be subtracted, resulting in successive negative offsets to the output. A smaller step size will have the opposite effect, with successive positive offsets being added. When a rising voltage is fed via this particular setup to a VCO, rising "bubbles" will result.

There is also an offset adjustment to adjust the initial value to which the modulo will be applied. An optional switch will allow the number of modulo cycles to be limited between 8 and 1.

Of course that is not the only way this module can be used. It can also be used as an audio frequency wave multiplier. A triangle, sine or sawtooth waveform at audio frequencies can be modified to produce some pleasant reedy type sounds. As the inputs can be controlled by CVs, these timbres can of course be swept.

Serge Wave Multipliers ,visit http://www.cgs.synth.net/ for details on this module ,construction guide , bill of materials and pcb's .


From the Serge 1982 catalog :

For generating and modifying sound, the typical synthesizer patch is VCO-VCF-VCA, linked in series, with suitable control from keyboard, sequencer, or computer. The VCO generates the raw sound, the VCF dynamically varies the timbre (sound quality). and the VCA controls the amplitude and produces the envelope on the sound event. The Serge Modular WAVE MULTIPLIERS (VCM) provide a new link in this chain, representing an advance in synthesizer technology. In this typical patch, the Wave Multiplier could be placed just before the VCF. Like the VCF. the Wave Multiplier affects the timbre. Unlike the VCF, whose action is a subtractive process of filtering frequencies from the input waveform, the Wave Multipliers are able to dynamically process the input waveform to produce new harmonically-related overtones. This function should not be confused with Ring Modulation, since it is a non-linear process using a single audio input. Although it is possible to describe the effect of a VCF by saying the sound gets "bass-heavy", makes a "wah-wah" effect, or sounds "thin" to describe the sound of a Wave Multiplier is much more difficult. The input sound comes out richer in harmonics, somewhat similar to pulse-width modulation and to linear frequency modulation, but with a new characteristic timbre. The nearest we can come to describing the unique sound qualities (there are three different sections) is to say that they alter the timbre in exciting new ways, producing interesting alternative forms of signal processing which are unique in the Serge Modular Music System. Since there are three entirely separate and different types of Wave Multipliers in this module, an enormously varied palette of new effects can be synthesized.

The "Wavolver" Waveshaper by Ian Fritz as he present it here on this thread : http://electro-music.com/forum/post-323577.html ,visit his home page http://home.comcast.net/~ijfritz/sy_cir6.htm for full description on this circuit ,scope shots and demo , the brief description from there :


The waveshaper circuit described on this page produces a wide variety of evolving waveforms in response to an external control voltage. Driven by a triangle wave, it can produce an output wave that continuously evolves from a triangle to an antisymmetric pulse waveshape. In addition, the section of the antisymmetric waveform that is at a zero-volt level can be replaced by an evolving series of successively folded triangular sections, somewhat in the spirit of the popular Serge Wave Multiplier.

The "5Pulser" Waveform Generator by Ian Fritz ,presented in this thread http://www.electro-music.com/forum/topic-19084.html along with a demo of this module ,visit Ian's homepage for http://home.comcast.net/~ijfritz/sy_cir8.htm details on this module ,second version ,more demo recordings ,and a stripboard layout ..this short description is taken from there :

The "5Pulser" waveshaper produces a train of pulses whose number (and widths) are varied with a control voltage. At the lowest control voltage a single square wave is put out, whereas at the highest voltage a train of 5 pulses spanning less that half of the total wave period is produced. Two versions of the circuit have been implemented, one for a 0-5 V driving signal (appropriate for use with a VCO core), and one for a +/- 5 V signal (for use as a general purpose module.)

MFOS Wave Freaker Module by Ray Wilson ,visit the MFOS Synth diy headquarters for details on construction of this module ,demo ,and PCB's . http://www.musicfromouterspace.com

From the description by Ray Wilson :

If you're looking for some new waveforms for your synth you've definitely come to the right place. I have been asked several times to come up with a circuit that takes a basic waveform like a triangle or a sine wave and takes it in a new harmonic rich direction. This circuit takes a triangle or sine wave (or other non-square wave) and allows you to turn it progressively inside out yielding a totally cool sound (peak inversion). Additionally the triangle, sine (or ramp/saw) is converted to what I refer to as a step waveform which has a cool hollow harmonic-rich type of sound. The modified triangle or sine wave output is further enhanced by the addition of a mixer for pulse wave, sub octave square wave and sub-sub octave square wave for very interesting harmonic rich sounds. You'll love the dry sounds you get but when put through a resonant filter your ears will get a real treat. Finally some new waveshapes beyond sine, tri, ramp, saw and square.


Features

Turns a Triangle or Sine Wave Into a Harmonic-Rich Waveform.
Provides several waveforms:
Inverted Peaks Wave (CV modulation capable)
Stepped Wave (CV modulation capable)
PWM Rectangle (CV modulation capable)
Square Sub-octave of fundamental
Square Sub-Sub-octave of fundamental
Voltage Controlled Wave Shape Modulation
Voltage Controlled Step Wave Modulation

Dual Sine Suboctave (og3) by Scott Bernardi ,this is his description given on the page dedicated to this module http://www.bernacomp.com/elec/og2/og3_sine_suboctave.html :


I got the idea for this circuit from a Synth-DIY thread. This suboctave unit accepts a +/-5v sawtooth and generates the following waveforms within the circuit:

Inverted saw
-1 octave saw
-1 octave square
-1 octave sine
-1 octave triangle
-2 octaves saw
-2 octaves square
-2 octaves sine
-2 octaves triangle

The sine suboctaves have the advantage of adding a big bass boost without adding a lot of buzzy harmonics.

The output mixer has pots to mix in the original saw with the other waveforms. This implementation mixes in the square and sine waveforms only, but it would be a pretty simple matter to mix in the suboctave sawtooths (sawteeth?) and triangle waveforms also.

The circuit is designed to handle a +/-5v sawtooth at the input. I added the INV switch to be able to handle either up-ramp or down-ramp saws. You can also get some very interesting waveforms by purposely having this switch in the "wrong" position.

Diode Function Generator (a la Analog Computers) by Ricko ,presented in this thread http://electro-music.com/forum/topic-32388.html ,here is his description on this circuit :

I was looking at Analog Computers a couple of months ago, and worked up this version of a Diode Function Generator. Think of it as a more variable version of a diode waveshaper. (There is some interested archival material on the web, from the 50s and 60s!)

It would be easier to use if it could be used like a graphic EQ (like the bar display with dither circuit). As it is, each step effects every step to the right of it.

I haven't built this, just simulated it in TI-SPICE. There is a full version. (It is also a simplified version at http://electro-music.com/forum/topic-28527.html )

Cheers
Rick

CV Twister / Wave Warper adaptation by Grant Richter . From the description on the site http://www.musicsynthesizer.com/diy/grant/CVtwister2.html :


This is a circuit adapted from the Sandin Image Processor. The original circuit was used to give "solarized" effects to video signals.

With some redesign it also makes a nice low parts count control voltage twister / wave warper circuit for audio. The bandwidth is limited by the op-amp type, and should extend above 20 Khz with this design.

The basic idea is to use diodes to split the input voltage into three sections - plus, minus and "near zero". Each section is then run to a scalable follow/invert circuit. Since the breakpoints are fixed by the diode voltage drop, an input "span" control allows adjustment of the breakpoint relative to the input voltage range. The output "Gain" control then allows boosting the signal back up to the 10 volt range. The sections could also be 3/4 of a quad op-amp. The 5.1K resistors and 10K pots could also be 47K or 51K and the pots 100K. The higher current of the 10K makes the breakpoints a little sharper, but it should still work with the higher resistances.

Serge Positive Slew ,more information on a classic Serge modules as well as PCB's at http://www.cgs.synth.net/

From the page dedicated to the Serge Positive Slew http://www.cgs.synth.net/modules/cgs83_positive_slew.html the following short description :

This module is a variation on the 1973 Classic Serge Positive Slew module. It is a forerunner to the popular Dual Universal Slope Generator. It is presented here for those who want to build themselves a classic Serge. There are two Positive Slew modules on the PCB. It can be used as both a rising slew rate controller, or a upwards sloping ramp LFO by hooking the lower pulse out into the Start input. In this configuration it also operates as a utility oscillator, suitable for fixed key sequencing and general sound effects and noise making. It is not suitable for tracking a keyboard.

Dual Universal Slope Generator by Serge
Visit http://www.cgs.synth.net/ for detailed information ,construction guides on Serge modules as well as PCB's

From the original Serge kit assembly instructions the description :

The DSG can be used as a slew limiting processor to change discrete voltage steps into gliding voltages (portamento). Voltages from a keyboard, sequencer, or other sources can be applied to the IN jack, and the RISE and FALL knobs will now determine the rate of glide in the positive and negative direction, independently.

The slopes from the DSG are linear (equal voltages per unit of time), but they can be altered using feedback. If the OUTPUT is patched to the VC IN jack, then the slope can be given an exponential or a logarithmic shape determined by the amount of feedback set by the processing knob. Since both the RISE and FALL can be switched to be controlled separately or together, the slope of either or both can be shaped using this technique. This is useful for producing slow, gradual amplitude changes with the Equal Power VCA modules.

If the TRIG IN jack is connected to the TRIG OUT jack, the DSG will oscillate with a waveform and frequency set by the RISE and FALL knobs. A series of pulses will appear at the TRIG OUT jack, and the duty cycle (the time the pulse is high compared to when it is low in each cycle) is set by the RISE and FALL knobs. The FALL knob determine how long the pulse is low. When the DSG is in the RISE part of the cycle or when the output is zero or less, the output of the TRIG OUT will be high. In some applications, a pulse with a very long duty cycle will cause erratic triggering in other modules. If such a symptom occurs, try increasing the FALL time and decreasing the RISE time to get the same pulse rate.

The DSG may be used as a positive peak follower by setting the RISE time to minimum (full CW) and applying an audio signal to the IN jack. Adjust the FALL knob for a compromise between response time and the best filtering of the audio component at the DSG output. If the FALL time is turned to minimum, and the RISE knob adjusted for optimum response time and filtering, then the unit will function as an envelope, follower-producing a negative envelope corresponding to the negative peaks ofthe input audio signal.

Adjustments on the DSG board are set to obtain a 0 to +5 volt level when the unit is cycling, producing a 100Hz triangle wave. An oscilloscope is required for this adjustment. This should not need to be adjusted unless components are replaced.

Triangle thru zero VCO by René Schmitz ,visit his page for more details on this VCO , demo sounds , other synthesizer modules designs as well as OTA Tutorial and in depth guide on exponential convertors and temperature compensation http://www.uni-bonn.de/~uzs159/index.html the short description on this Oscillator by René Schmitz :

A thru zero oscillator is one that can go forward and backward. This allows for deeper frequency modulation. Sonically there are interesting a little yamaha-ish sounds possible. This oscillator sounds somewhat dirty when the modulation index is time variable. But clean non-time-variant timbres are possible.

Voltage-controlled digital oscillator VCDO1 by Tom Wiltshire ,visit Electric Druid homepage http://www.electricdruid.net/forums.html for a full detailed PDF on this Oscillator ,and more digital based synthesizer modules along with ASM code and assembled HEX code .
From the description on this Oscillator given there :

A single chip 1V/Oct voltage controlled digital oscillator, with 20 waveforms in a scannable wavetable.

The VCDO uses a PIC 16F1847 microprocessor to create a versatile and simple voltage-controlled 8-bit digital wavetable oscillator. All oscillator parameters are controlled by 0-5V control voltages. The chip has a native exponential control response, making interfacing with 1V/Oct control voltages very simple, even without an exponential convertor.

Main features of this Oscillator :

- Exponential frequency response with no exponential convertor
- 10 octave note range from 8.18Hz to 8372Hz
- Main Oscillator with 16 waveforms arranged as a wavetable
- Separate Sub Oscillator with 8 waveforms at four octaves
- Bitcrushing effect
- Glide/Portamento
- 8-bit, 62.5KHz sample output rate
- Easy interfacing to control voltage mixers

PLL FREQUENCY MULTIPLIER MODULE By Scott R. Gravenhorst
Originally designed for PAiA FatMan

From the description Scott gives on his page http://home1.gte.net/res0658s/fatman/4046pll.html :

This circuit is a multi purpose phase locked loop designed for frequency multiplication (harmonic generation). Although it was designed around a PAiA FatMan, it should be adaptable to almost any analog system. The circuit is based on a 4046 type micropower phase locked loop IC and uses a divide by 12 counter inserted in the loop to force the PLL's VCO to run at 12 times the input frequency. It's output is provided as a set of 7 different square waves representing octaves and perfect 5th harmonics of the input signal. If you build this for a system other than the PAiA FatMan, you must design an appropriate attenuator or amplifier, whichever is necessary for your system or mixer. This should be fairly simple, being not much more than a voltage divider (attenuator) or an Op Amp buffer.

Much like a VCO (or in this case, 7 VCOs), this is a sound generating module, intended to enhance a synth by tracking a VCO to produce it's own waveform at 7 different harmonic frequencies. Wherever the source VCO's pitch goes, so does the phase locked loop. Because it is a phase locked loop, it has characteristics of it's own, such as controllable lag and over/undershoot when the input frequency changes.

The circuit works for a FatMan as designed and drawn. If you are building this for a system other than a FatMan, you may need some kind of conditioning for the 4046 input, such as a schmitt trigger or op amp or both. This circuit works well with a -12V pulse or square wave (pulsating DC, negative going) input.

Here is a list of some harmonics and their interval relationship back to the fundamental:

2f 1 oct
3f 5th + 1 oct
4f 2 oct
5f maj 3rd + 2 oct
6f 5th + 2 oct
7f min 7th + 2 oct
8f 3 oct
9f 9th + 3 oct
19f minor 3rd + 3 oct
27f 6th + 4 oct

WaveThing Multiply/Divide Wave Shaping Circuit by Scott Stites ,as he present it on the following thread http://electro-music.com/forum/topic-33149.html&postorder=asc , from his post :

For the past number of weeks, I've been designing a series of VCO embiggeners that I call the "WaveThing" series. Here's an offshoot of one of the designs that might come in handy for someone. I figured I'd break this one off before it turned into one of my more complex designs, as they are all wont to be. This one is fairly simple yet very effective.

It's a design that derives octave-down sawtooth, triangle, and pulse width modulated waveforms from a single downward ramping sawtooth input. I didn't take the extra step to put in a triangle-to-sine converter on the triangle, because I personally prefer a triangle wave as the "unobtrusive" sub-oscillator (the smooth add-meat-but-not-buzz signal). Sawtooth is a great sub-oscillator waveform, and a nice break from the standard square wave sub-oscillator. The pulse output can put out square waves, or fixed pulses of any width, or (really meaty-beaty-big-and-bouncy) a pulse-width modulated waveform.

The circuit should run on either +/-12V or +/-15V. I'm using 15V; 12V may require different values for R14/R15 to get full 10Vp-p output. It *must* be fed with a downward ramping sawtooth. The sawtooth output is also downward ramping. If you don't have a downward ramping sawtooth, an inverter or a switchable inverter for the input can be easily put in. You would want to keep the sawtooth output the same phase as the sawtooth input that you are using (mixing an upward sawtooth with its downward one octave down counterpart can dull the sound). An inverter for the output and input can easily be accomplished with a SPST switch, I believe. Or, if you never intend to put in a downward sawtooth, just put an inverter on the front end and connect the Q output of the flipflop to Q2 (instead of /Q), which will cause the circuit to generate an upward ramping sawtooth.


Note the power connections on the two CMOS parts. Half the flipflop is not used and two thirds of the CD40106 is not used, either. One could probably put in an extra octave down with those parts. I haven't, because that's not the direction I'm going with this series. Wink

The one trim on it is easy to do - you just tweak it until the sawtooth output has a smooth, unbroken ramp. Very easy - just connect the dots.

Cheerios,
Scott

Voltage Controlled Divide by N by Juergen Haible (from JH-3)
comment by Juergen Haible on this circuit :



I prefer this way of clock division to the "digital" FlipFlop / Counter method. The circuit works nicely for both clock division and at audio frequency (subharmonic generator).
