New Vaemi XFMR VCA

video uploads by Vaemi

"Vaemi's new module XFMR VCA, which is designed for Eurorack systems, introduces users to a transformer-based VCA design.

Turkey-based Vaemi (Volt Age Electronic Musical Instruments), which commercially produces synthesizers and electronic musical instruments, recently released its first module, the Osi-Op (through zero fm VCO), and quickly followed with other Eurorack modules such as Shift Register, R2R Ladder, Buffered Multiple, making a name for itself. Now, it has introduced and brought its users the new XFMR VCA module, which is handcrafted with high-quality, through-hole components and features an audio transformer in its output.
The XFMR VCA is a VCA with linear curves. It has two separate audio outputs, such as the classic Op-Amp and the Transformer Output feature that gives it its name. It is AC Coupled and designed specifically for audio signals, making it a VCA module that you would want to use at the end of your chain. You can use it to add saturation, harmonics, and EQ to your patches made with the Osi-Op and through zero fm techniques, or use it for a clean range if desired. This wide range of options will be loved and make you feel comfortable.
Additionally, the XFMR VCA has an expander that allows you to expand it up to 3 channels. With the expander, you can have two more exponential VCA channels, which you can use for frequency modulation of oscillators or in other places you need them.
In studios, preamplifiers are equipment that can properly raise the microphone or line signals level without distorting or adding noise to the sound. However, when recording analog synthesizers, we tend to lower the sound instead of raising it because they have very high outputs. At this point, we thought that one of the most important things that preamplifiers add to recordings, other than gain, is audio transformers.
The XFMR VCA also has an EQ stage. This will provide great flexibility when finalizing your last patch, especially in multi-channel patches, and will provide a more accurate and clean sound in live performances.
Vaemi aims to create systems that can comfortably be used in today's electronic music and popular synthesis techniques such as additive, FM, Formant, Subtractive synthesis, and will continue to shape and evolve with new module designs that will be released in the coming year.

FM Synthesis Made Easy on Aalto Modular Synth for Your Computer by Madrona Labs

"Try patching in the DAW on Aalto Modular Soft Synth VST today.
Free demo download at

By using two simple waveforms — one, as the audible 'carrier' whose frequency is modulated by the other (our LFO) — we can create harmonic or inharmonic tones using very rapid vibrato, based on the frequencies of these waveforms and the depth of the modulation.

FM synthesis was first discovered in the 1960’s by an ex-GI turned artist, John Chowning, who was initially scorned by his academic composer peers for his desire to make music with an //inhumane//computer. The speed by which a computer can modulate a waveform created new sounds beyond the capabilities of acoustic and analog instruments: the birth of a new sound! ✨

We can thank FM synthesis for the sounds of the 1980’s w the popularization of the Yamaha DX7 which allowed FM synthesis to infiltrate video games, movie soundtracks, and of course the power ballads! (Take My Breath Away! Take On Me!)

Relive the '90s with the Roland JD800: Factory Presets

video upload by Andy Whitmore


The Roland JD-800 is a digital synthesizer that was manufactured between 1991 and 1996. It features many knobs and sliders for patch editing and performance control — features that some manufacturers, including Roland, had been omitting in the name of streamlining since the inception of the Yamaha DX7. The JD-800 thus became very popular with musicians who wished to take a hands-on approach to patch programming. The introduction in the manual states that Roland's intention with the JD-800 was to "return to the roots of synthesis".

The JD-800 employs Linear Arithmetic synthesis (introduced and made famous by the Roland D-50), which combines sample playback with digital synthesis. The JD-800 has 108 built-in waveforms, which can be expanded via PCM cards. The waveforms span a variety of categories such as analog synthesizers, acoustic instruments, and voices. Many of these waveforms are very short and are used primarily for the attack portion of a sound, while longer ones are used for the sustained part of a sound. The JD-800 was Roland's first instrument to have its core presets developed entirely in the United States, under a short-lived branch of its R&D-LA office in Culver City, California. The core sampled waveforms and factory presets of the JD-800 were created by Eric Persing.

A patch, or single sound, in the JD-800 consists of up to four tones. As every tone consists of an almost completely independent synthesizer voice, a patch could be considered a combination of up to four different synthesizers. In Single mode the JD-800 plays one patch at a time, but in Multi mode it is possible to play five different patches over MIDI, plus a "special" patch. The special patch has different waveforms assigned to the 61 different keys on the keyboard, so is used for drums and percussion sounds. The JD-800 has one effects section. In Single mode, seven effects can be used simultaneously, in series, so all tones in a patch go through the same effects. In Multi mode, three effects can be used at the same time, with all patches sharing the same effects, though any of the patches can be routed to bypass the effects.

Tandem random sequences with one-finger performance on Mellotron, Moog clones

video upload by glkibler

"The 5U modulars I'm using here are two prototypes I hand-built in 2014 using mainly Yves Usson's (Yusynth) circuit designs - ones, I might add, that I painstakingly transcribed from his original printed circuit designs to my own veroboard layouts. These were originally housed in cheap Ikea bookshelves but last year I broke down and bought two very nice-looking cabinets, though I retained my own power supplies. The two 960 sequencers above are simply Behringer 960s I had re-housed inside full-size matching panels and cabinets."

"Start with the Side Panels, and add-on any of our available accessories, including the Eurorack Extension Cases. Side panels slide over existing sides and requires zero assembly skills. You can have your system together in 10min out of the box. The side panels are required to use the Eurorack cabinet and are not included with the cabinet. Please see short video for a demonstration on how they work.

The Matriarch Cabinet is one 150HP row of standard Eurorack 3U format and one 150HP row 1U Intellijel.

Cabinet includes one Eskatonic Modular powerboard and customer power plate. You’ll need to provide your own DC Brick to power the system. We recommend this one found at many online retailers:

"Very nice 4 part CV/Gate sequencer with nice features and ease of use.

This unit was serviced:
- the original battery leaked like on many of these units. It was repaired and a 2032 coin battery was installed on socket for easy replacement in a few years
- Power supply was set on 240v for european countries (was on 220v. Other voltage will need a converter)
- switches were cleaned
- full calibration"

Doom approaches

video upload by Richard DeHove

"Not depressed enough about everything yet? Maybe this can help! Here's the DB-01 synth in a single take with a little help from some pedals. No other music or processing. Sampled voices are from the brilliant 1984 UK movie "Threads" a harrowing, grim and completely believable movie about the lead up and aftermath of a global nuclear exchange. There's no happy ending.

(And yes, for anyone who saw my last video this is exactly the same setup - I was noodling afterwards and this just fell out).
