FusionLab ION Synthesizer

video upload by Toine Scholtz

"A little video demonstrating the Ion, a digitally controlled analog monosynth that I built a while ago. All the music in the video was created using the synth only (sequenced from and recorded into Ableton Live).

I started sketching the concept for the synth nearly 10 years before I began the build, but had a great deal to learn about analog and digital electronics before I was capable of actually building it. I arrived at the final design around mid-2020, began the build late 2020, and completed it a few months into 2021.

The synth is controlled by MIDI over USB. I used a PJRC Teensy 3.1 microcontroller and several DAC ICs to generate control voltages.

The Ion has 3 VCOs, each producing a slightly different selection of waveforms, and a noise source with its own state variable filter. Each VCO can produce a pulse width waveform, and each has a dedicated LFO to control PWM. There are two main resonant VC filters, each with continuously variable responses between LPF, HPF, BPF and notch. The filter configuration can be continuously faded between series and parallel.

The synth has a main VCA with dedicated envelope generator, and each VCF has a dedicated EG controlling cutoff frequency. A dedicated LFO can control the frequency of one or all three VCOs. Three other modulation sources, an EG and two LFOs, can be routed through the modulation matrix, a two channel matrix with 7 sources and 8 destinations available on each channel. Each VCO output can be also used as a mod source, as can the noise source. The matrix destinations include VCO pitch, VCF cutoffs, and AM of one of the VCOs and the main VCA.

The synth uses a Doepfer DIY synth board, which provides one of the VCOs, one of the VCFs and its envelope generator, the main VCA, the pitch modulation LFO, and the slew limiter used for the glide control. All the remaining modules are either completely discrete or make use of dedicated synth chips.

The design of VCO1 is adapted from Thomas Henry's astoundingly good VCO-1. The second VCF derives from Thomas Henry's beautiful VCF-1 design. VCO2 uses the AS3340 clone of the classic CEM chip. One of the mod source LFOs is based on a very elegant Ray Wilson design, and the other mod source LFO and envelope generator (as well as the main EG and the EG modulating the other VCF) are build using the fantastic modulation chips designed and supplied by Electric Druid. The noise source is also based on the Electric Druid noise generator IC.

In practice, the synth architecture is predominantly subtractive, but the mod matrix means it's also possible to do basic FM, although that's fairly limited by there being only two mod matrix channels (mod matrices are difficult and expensive to implement).

The synth cost about 5 months of spare time, more money than I have the courage to calculate, and some intense stress and frustration in getting it to work properly. Debugging hardware is much more difficult than debugging software.

It was an amazing journey of learning, and I'm one step closer to knowing how not to build a synth. It also gave me an even more acute and humbling appreciation of just how astounding is the work done by the synth electronics pioneers, and indeed contemporary designers. I stand, diminutive, on the shoulders of many giants.

Alemanlabs OSEG - One Shot Event Generator by Tom Wiltshire

Published on Dec 24, 2019 Pete Aleman

"This is a fun module designed by, Tom Wiltshire. The pcb and panel are designed by Alemanlabs. 10hp

'Here’s something slightly different! Is it an LFO? Is it an envelope generator? Well, it’s a bit of both. It produces a one-off event like an envelope generator, but it has a selection of waves more like an LFO.'

New Alemanlabs Tap Tempo LFO and M-172 Phase Shifter Eurorack Modules

Published on Jun 16, 2019 Pete Aleman

The modules are currently for sale by Alemanlabs on Reverb. Note this is the first Alemanlabs post on the site.

"This is a quick demo of two Alemanlabs modules. The two modules are the, "Tap Tempo LFO" by Electric Druid, and the other module is a clone of the 6 stage Phase Shifter from the Roland 100-M modular. Im using one of the LFO's to modulate the Phase Shifer and the other LFO to modulate an SH-1 filter. I am also using an LFO to modulate a VCO.

One of the key features of this LFO is the ability to sync the LFO to a beat. In this example im syncing the LFO's to a trigger out from the Arturia Beat Step Pro."

Features

Simple “Tap Tempo” control button.

The TAP TEMPO input can measure the time between two taps of a momentary switch or button, and uses this time to set the LFO’s basic tempo.

Ability to synchronize LFO to external clocks

The TAP TEMPO input can also accept 0-5V pulses. This allows the LFO to be synchronized to an external clock. The module also produces a CLOCK OUT which can synchronize other TAPLFOs.

LFO range from 0.025Hz to above 50Hz

The basic range of the TEMPO CV allows the LFO to produce frequencies between 0.05Hz (a 20 second cycle) and 12.8Hz. However, in conjunction with the MULTIPLIER CV, this range is extended to 0.025Hz (a 40-second cycle) to 50Hz.

Sixteen output waveforms, in two sets. The chip can produce 16 output waveforms. These are selected by the “A/B” switch.

The MULTIPLIER selects a tempo multiplier which is used to determine the final LFO frequency. This allows the LFO to produce changes at double or half-speed, or produce triplet times.

Wave Distort. The selected waveform can be distorted using the DIST pot. This modifies the duty cycle of all LFO waveforms.

Smoothing filter switch. This applies the digital equivalent of a single pole RC filter to the waveform before it is output. The filtering removes the abrupt edges that tend to give clicks in some applications and gives the waveforms a softer rise and fall (about 20msecs).

Built in fuses on the power input protect the module from over current conditions. If the module experiences any kind of over current condition the fuses will over heat protecting the module. The fuses will reset once power is recycled.

The panel is laser cut, drilled and silk screened with epoxy based ink."

ARP 2600 configuration of a Synthesizers DotCom portable 22 cabinet

Published on Dec 27, 2015 O.Z. Hall

"This is a brief overview of a DOTCOM modular system in a Portable 22 cabinet. It was configured to have the capabilities of an ARP 2600 (minus the pre-amp, envelope follower and voltage processor sections). It features a normalized signal path and a "programmer" which supplies a mix of envelope generator, LFO, bias (cutoff) for the VCF. It also provides voltages to control the resonance, tuning of VCO3, Envelope generator controlling the SYNC effect (from the IAN Fritz 5 Pulser), and the "Fat" CV for the Synthia Saw Animator module."

Radio Music in the Clouds

Published on Sep 14, 2015 Modular Cult

"First experiment with the Mutable Instruments Clouds.

The Music Thing Radio Music is patched into the Clouds module via a CGS/Serge 1973 VCF. The Radio Music is patched almost exactly like my previous video, but I am also modulating the Station input. The output of the Clouds is set to 100% wet and I am modulating the Reverb amount via the Ian Fritz Chaos module.

The bass drops are an Electric Druid VCDO. The FM type sound is two Yusynth VCO's inter-modulating each other and feed into a MFOS EchoRockit."
