1517 THE MUTANT MACHINE Dynamic Analog Percussion Engine
MICROCONTROLLER FREE ANALOG PERCUSSION SYNTHESIS
unique Inverter Core oscillators form the MEMBRANE. Each analog oscillator has three waveforms to select from
capable of synthesizing everything from heavy-hitting bassdrums to classic 909-style snares and other complex timbres
modular design gives the Machine many auxiliary purposes, great for modular sound design of many varieties, and not just percussion
the SNAPPY section is comprised of a voltage controlled noise oscillator, for modelling the noisy part of drum timbres
both MEMBRANE and SNAPPY elements have an external input for replacing the built-in sound sources, opening up many avenues of possibility
13 control voltage and audio inputs, for a fully modular drum experience
7 audio and CV/gate outputs for maximum integration with other modules
dedicated outputs for each WAVE and NOISE oscillator mean you can use the Machine as a complex VCO in your system, when not synthesizing percussion
WAVEFORM SCANNING FEATURE GENERATES COMPLEX TIMBRES
the MEMBRANEâ€™s waveforms can be scanned through automatically by the wavescannerâ€™s voltage controlled clock generator, or an external clock or VCO can be used
SCAN FREQ CV forms a unique form of timbre control, making the Machine act like a complex oscillator at its WAVES output
the ENABLE input allows you to gate the wavescanner on and off with a CV or gate signal
ARCHITECTURE OF THE MACHINE
The Mutant Machine is a dynamic analog instrument capable of generating a wide palette of sounds, ranging from various forms of analog percussion to complex drones and oscillations. To achieve this, the Machine features two synthesis sections which are summed together at the final output: MEMBRANE and SNAPPY. Like the other Mutant Drums, the MEMBRANE and SNAPPY circuits began their mutation as classic analog percussion techniques and have been reimagined for 21st century modular synthesis.
The MEMBRANE forms the main body of the sound by way of two analog VCOs, and the SNAPPY section further adds to the timbre by contributing noisy elements to the mix. A noisy CLICK which occurs at the beginning of the SNAPPY sound can have its volume adjusted independent of the main decaying SNAPPY texture.
The waveforms which make up the MEMBRANE can be selected manually by button press, or the WAVESCANNER can be used to automatically scan through the available analog waveforms. By modulating the frequency through which waves are scanned, unique, complex sounds are created.
Experimentation is encouraged by the many modulation inputs and outputs available to you. The Machine features 8 CV and gate inputs for modulation as well as two external audio inputs, for bringing other modules into the Machineâ€™s core. There are many audio outputs for maximum versatility, allowing you to use the Machine to create drones and alien timbres for use elsewhere in the modular analog system.

I have started to build a (slightly) updated version of the Korg PS-3200 synthesizer.
The PS-3200 was the last of three fully polyphonic, semi-modular analogue synthesizers offered by Korg in the late 70's. (See Ben Ward's excellent Korg PS site for detailed information, including user manuals.)
The concept of the PS-Synthesizers was different from other manufacturer's early polyphonic instruments. Instead of using a small number of voices and a clever keyboard assigning circuit, the "PolyKorgs" had a complete synthesizer circuit, hard wired to each key. That makes a total of 48 VCFs, 48 VCAs and 48 voltage controlled ADSRs even for the smallest of the range, the PS-3100. The largest of the range, PS-3300, even had 144 of these circuits.
The sheer number of synthesizer circuits called for an extremly economic circuit design, and it's a joy to look at Korg's design ideas which led to building blocks that almost did the same as in the better known "classic" synthesizers. And after many years of engineering and reverse-engineering electronic music circuits, I have learned to look at odd solutions not as "substandard", but as a source of creativity an individual character. Here's a list of some highlights:
Function Implementation Side effects
Single-Transistor Waveform Converter creates triangle, saw, pulse and PWM from saw input, using one (!) transistor, one diode and two resistors per voice, plus two global control voltages Pulse height also changes with pulse width
5-Transistor-VCF (Korg-35) A Voltage controlled 2-pole (Sallen&Key) LPF built from 5 transistors rather high CV feedthru
Single-Diode VC Resonance The dynamic resistance of a simple diode is used to alter the feedback gain of the VCF limited range of Q
"Expand" function instead of VCF Envelope modulation depth Instead of scaling down the ADSR with a VCA, the a variable portion of the Envelope is just clipped with a single diode. It's so remarkably close to ordinary VCA function that apparently nobody takes notice. At least I have not read about it anywhere.
At slow Atack times, the Envelope appears delayed at the VCF (no effect until th eclipping point is reached). Usefull for Brass sounds, and not easy to emulate with conventional synthesizers.
Minimum parts count Voltage Controlled ADSR Three transistors, 1/2 of a LM324 and one CD4007 per voice. Plus some more involved control circuit, shared by several voices Transistors must be selected in 13-tuples, not just in pairs.
ADSR detail (1):
One-opamp control logic 1/4 LM324 is used as Flipflop, which is dynamically set by Gate-ON, dynamically reset by Gate-OFF, statically reset when the attack peak voltage is reached, and whose set/reset sensitivity is altered by a CV Very odd "Hold" function, depending on the "Attack"-value. But very useful in practise.
ADSR detail (2):
Single-Transistor, exponential slope VC-Decay Using a single transistor per voice for VC Attack and Release is remarkable already, even though the A and R slopes are linerar. But the Decay slope is exponential, and this is achieved with a single transistor and two resistors per voice! The Decay time range is rather limited. No ultra fast Decay, and no ultra slow Decay either.
Single-Transistor VCA That's the "Korg standard" VCA, well known from other instruments like the MS-10.

347 Pixelh8 - Multidisciplinary Artist and Techno Anthropologist Â» Software
The Pixelh8 Music Tech Master Stroke DS is a real time synthesizer for the Nintendo DS system it allows for extensive sound design and is the natural evolution of the Music Tech Series allowing for the classic chip tune sound on a modern device.
The new system allows for keyboard style play by pressing â€śXâ€ť to bring up the 2 Ocatve Xylophone or classic Music Tech mode by using the directional pad to control the sounds in the same way as the Music Tech Game Boy and Pro Performer Game Boy Advance.
Loads of new combinations are possible as you can now combine interval settings with time based effects as well as using the noise channel instead of tone and the easy change between menus allow for quick change during performance.
All sounds are produced via the on board sound chip and no samples or sample manipulation is used, this is a real time chip tune synth for the DS.

300 YAMAHA CS-30 SYNTHESIZER
This page is dedicated to the Yamaha CS-30, the monophonic top-of-the-line of Yamahas CS-series synthesizers. This synthesizer series comprised of the CS-5, CS-10, CS-15 and the CS-30. These were all monophonic. The polyphonic series comprised of the CS-50, CS-60 and the classic CS-80, Later came the CS-30M and CS-40 monophonics as well as the CS-70 polyphonic with some patch saving capabilities and different design.
All the units of this series of vintage synthesizers are very nice and collectable, but the CS-30 was the largest and most flexible of the monophonic series. If Yamaha had ever decided to build a large modular system they could have done so using some of the designs of the CS-series.
In this page I will go through the features of the CS-30, for anyone interested.
235 MATRIXSYNTH: Alesis Andromeda A6 Aurora Mod
This was a custom mod. I originally put a post up in August of 05 here. Anyone know the website where more info on this mod is hosted? I accidentally lost the link when mucking around with Blogger's settings a while back.
This image via Photobucket
Update: I found the original site but it is down. Some info and additional shots pulled from the Internet Archive Way Back Machine. You can find some thumbnails there, but most give you a 404 if you click on them for the larger shot. I pulled the large pics below before they are gone forever.
"Alesis made Synthesis History when they released their Alesis Andromeda A6, an analog polysynth bred with new technology and classic analog sound! Sixteen awesome voices with two types of filters, a vast modulation system, and enough bells and whistles to make the Andromeda A6 THE most highly featured analog polysynth in existence. If it only had a sloped panel...
* Take one Andromeda, lightly used (but out of warranty - very important!)
* Add one black on blue BETA Panel - because the pre-production beta panels were lacking the Pre- and Post-Filter Mix VIEW buttons, either the buttoncaps must be pulled off of the switches on the PCBs OR two holes need to be carefully drilled through the panel to accomodate. I drilled the holes after measuring about fifteen times each.
* Tilt that panel at approx. the same slope as the Korg MS-20. Requires the extending of a couple of ribbon cables inside, and some pop-rivetted braces. Not too hard.
* Custom wood endcheeks of nice Oak, plus a wood accent over the keyboard. I chose to go with thick, high quality wood to make Aurora more of a beast.
* Replace all green LEDs with red high-intensity ones. This also required changing some resistor values to increase the brightness.
* Replace the LCD with a Hantronix Blue-on-White display. Also, some resistor changes are needed.
* Have a very agreeable Alesis burn a custom Boot EPROM with the custom-designed bootup screen below.
* Build a custom top panel, complete with several additional controls (two joysticks, several switches and knobs) as well as a full 16-channel mixer with level and pan per channel, one for each of the 16 individual outs on the Andromeda.
* Add lots of careful, hard work and time, and PRESTO - you have the Aurora A6!
The Name: I went with Aurora for a couple of reasons.
1. Alliteration - AurorA - AndromedA - get it?
2. There is some legend/lore as to how the Alesis Andromeda got its name. Could be related to the Greek mythos. Could be related to the Andromeda galaxy. Could be darts thrown at dictionary pages :-) In any case, Aurora fits with the mythology bent because in Roman mythology, Aurora was the goddess of the dawn (Andromeda was rescued and married by Perseus in Greek mythos). Aurora also fits the 'celestial' thing as well, as the Aurora Borealis. Either way, it kept with what might have perhaps been Alesis' reasons for naming the Andromeda.
3. I just liked it.
4. The A6 is kept because this fits with Alesis' naming convention (QS8 = 81-key QuadraSynth, A6 = 61-key Analog). There is some rumor that A6 was a play on ASICs, the custom chips within Andromeda, but I'm assured this is just rumor :-) "
