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 MEMBRANE’s waveforms can be scanned through automatically by the wavescanner’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 Machine’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.

1043 Monotribe, MIDI and me
synth When I heard about the monotribe, I had my doubts. Mostly that there’s only one pattern, which is 8 steps long. Well, there are 8 extra steps for the drums, as well as a “flux mode” which records your movements on the ribbon continuously. In that sense, it is limited, and is an instrument made to be played with your hands, rather than be programmed. But as it turned out, this was a design choice, and not a technical limitation. I can easily imagine why. They wanted it to seem as analog and playful as possible. Same thing with MIDI. Officially, the monotribe doesn’t support MIDI. It does however offer a sync pulse output and input. This allows it to be synced to other monotribes, modular synthesizers or even Korg’s own virtual iMS-20/iElectribe, using a special sync app on a second iPhone/Pod/Pad. However, the lack of MIDI is still a slight limitation.

884 jh_polykorg_clone
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.
