Yamaha FX-1 FM based organ

George Benton

"General overview of the very large and ground breaking FM instrument from Yamaha in 1983. Sold for around 35K or more, it was the flagship of FM organ technology at the time. That same year, the DX-1, DX-7, DX-9 were introduced. This organ weighs 507 pounds. The bench is nearly 154 pounds with the pedals being 55 pounds. That's over 700 pounds!"

PROLOGUE VS. JUPITER-X: Sounds From Scratch + Filters


"As requested!
It's another synth showdown- this time its the mighty (and massive) Roland Jupiter-X up against our favorite regular contender, the cool and confident Korg Prologue 16 (with strength-enhancing low frequency compressor!)

Who will win in this battle of super synth sounds? Are there even such things as winners and losers in the sonic battleground that is the modern music producers studio? Yes there are. And these are both winnnnerrssssss.

Couldn't get rid of that Deepmind12 fast enough, though. Sorry."

TomaTekAudio Demos

This is a follow-up to this post where you will find details on TomaTekAudio's new modules. You can find them on Etsy here.



"Thomas Hopman made an awesome Multimode Filter module for the Eurorack format which he was so kind to let me demo, so here are some soundbits I made using the different filter modes. Hope you like!


A bit more on the signal path:

All audio demos are recorded using the following audio path:

Generator -> Tomatek MMVCF -> Erica Synths Black Hole DSP 1 -> Stereo out to Befaco Hexmix -> Befaco Output v3 -> Zoom H6

Most Demos are recorded using an input gain level of around 11:30 on the dail.

My system is a bit noisey and these demos are far from audiophile quality, but I hope they give the character and sound of the filter the attention they deserve.


A bit more on the module:

The Tomatek Audio MMVCF.

a AS3320 based 12dB per Octave multi-mode filter module, with separate outputs for Low-Pass, Notch, Band-Pass and High-Pass.


- CV control over Filter Cutoff and Resonance, with a fixed V/Oct input, switchable attenuation/attenuversion on the FM input and attenuation on the Resonance CV input.

-Self-resonance with accurate temperature compensated V/Oct tracking over approximately 5 to 6 octaves.

-Input gain control with a soft-clipping circuit that kicks in at around the 12o'clock setting. Allowing for clean tones till unity-gain and soft-clipping and eventually hard-clipping the filter front-end at higher gain settings. When used in conjunction with a VCA before the filter, this will allow for a nice range of extra tones.

"Kawai SX240 in excellent condition, very little use, if you know how these behave when they've gotten a lot of use - Forget it.

It looks almost new apart from a few scuffs on the woodens sides, please see pics.

Screen is bright and buttons react very well, jog wheel perfectly.

Brand new battery replacement and Tauntek chip installed and the original hardcase is included.

Sounds like a dream: fat, versatile, flexible, it's all there - all factory presets except the two that we tried out for an extra memory check up.

Midi checked and fully compatible."

DivKid / SSF Rnd Step Eurorack Module Jam and Patch Walkthrough

Perfect Circuit

"DivKid teamed up with SSF to make the RND STEP module. We used the RND STEP to modulate parameters on both of the voice modules in this patch. The RND STEP is basically six noise generators going into six sample and holds with some clever normalization so you can generate six random modulations with one trigger.

In this patch we used the SSF Entity Percussion module to generate all of the drum sounds and the Noise Engineering Basimilus Iteritas Alter as a voice sequenced by the Make Noise 0-CTRL. The XAOC Batumi and ALM Pam's New Workout clock everything. We used the Future Sound Systems Gristleizer Filter to add some screeching resonance that can be switched in and out with the Afrorack and Ali Modular OR Switch. Everything is mixed together with the Cockpit.

Eurorack Modules by TomaTekAudio

Update: demos posted here.

TomaTekAudio is a new maker from Amsterdam, The Netherlands.

You'll find their modules available at their Etsy shop here.

Details on the first three follow.

Tomatek-Audio MMVCF.

a High-end AS3320 based 12dB-per-Octave multi-mode filter module. With separate outputs for Low-Pass, Notch, Band-Pass and High-Pass. Based on the design of the OBx-A filter, but with several tweaks and improvements.


- CV control over Filter-Cutoff and Resonance, with a fixed V/Oct input, switchable attenuation/attenuversion on the FM-input and attenuation on the Resonance CV input.

- Self-Oscillation with accurate temperature compensated V/Oct tracking over approximately 6 octaves, which allows for a very nice playable sine wave.

- Input gain control with a soft-clipping circuit that kicks in at around the 12o'clock setting, with typical eurorack levels. Allowing for clean tones till unity-gain and soft-clipping and eventually hard-clipping the filter front-end at higher gain settings. When used in conjunction with a VCA before the filter, this will allow for a nice range of extra tones.

- Makes use of high quality parts where applicable (Wima Polypropylene capacitors for timing, Nichicon Bi-polar audio capacitors for ac-coupling, Panasonic and Nichicon electrolytics, Texas Instruments Audio-Grade Opamps and of course ALFA AS3320 filter chip).

- 8HP width.

- current draw: +12V 25ma, -12V 25ma, +5V 0ma.

- Skiff friendly at 35mm deep."

Tomatek-Audio Matrix-4x2.

a 4 input 2 output dc-coupled mixer, capable of mixing audio and/or cv sources. The Matrix 4x2 has several uses, including but not limited to: attenuation, inversion, dc-offset, dual cv-mixer, stereo audio-mixer, audio-mixer with effects send/return


- Switchable attenuversion/attenuation per output channel.

- Switchable dc-offset on input 4: +5V / off / -5V, allows for mixing in dc-offsets..

- Bi-polar led on each output channel for signal visualisation.

- Expansion headers on the back allows for chaining multiple Matrix-4x2 modules. This makes it possible to expand either the inputs and/or the outputs.

- Makes use of high quality parts where applicable (Panasonic and Nichicon electrolytics and Texas Instruments Audio-Grade Opamps).

- Skiff friendly!

TomaTek-Audio MULT

Simple passive multiple configured for 1x6/2x3 operation.

By changing solder jumpers it is possible to change it's configuration to 2x3 without normalisation or 1x7.

The panel is reversible.

see github for changing the default configuration of this multiple.

All made with love in Amsterdam!

Gotharman's Dual Line SSI2140 VCF for Tiny LD

via Gotherman's Musical Instruments

"The Dual SSI2140 filterboard has 2 analog multimode filters. Each of these filters can be assigned to their own Audio Bus, doubling the Tiny LD analog filter power!

Each of the filters has 4 filter blocks. By combining these blocks, using VCA’s, it is possible to obtain a number of different filter modes.
It comes with 25 pre-programmed filter types, but it is also possible to adjust these, to obtain an even wider range of filter types.
If different filter types are selected for morph layer A and B, it will morph between the filter types.

Please note that your Tiny LD must have the VCF connector MkII installed, in order for this to work. All Tiny LD MkII’s, that were ordered with a VCF connector, has this connector installed. Later MkI’s might also have this installed. Please check on your receipt. The price of the MkII connector is currently EUR 170, while the MkI connector costed EUR 150. If your Tiny LD has the MkI VCF connector installed, and you would like to use it with the new dual line filter, it can be upgraded at Gotharman’s for the price difference."

FUNDAMENTAL - New Test Equipment VST by SonicLab In Collaboration with HAINBACH


"In which I am proud to release the VST instrument I have been working on for half a year with Sinan Bökesoy of SonicLab. Crafted with love and care, this is a rich-sounding and exploration-inviting tool for your music. Its steeped in history, but can be adapted to any music style."

Fundamental - the root of electronic music brought into the now.

Sinan Bokesoy

"Fundamental feels like something Stockhausen, Xenakis and HAL 9000 might have dreamed up after a bender. Recalling the past of electronic music and reconstruction of a massive german vacuum oscillator on a modern instrument with immense possibilities. Proudly presenting a collaboration of sonicLAB and Hainbach."

"Fundamental is a sound synthesis software tool combining the different roots of electronic music history. Fundamental wave engine is a faithful sonic recreation of a vintage Rohde&Schwartz vacuum tube oscillator ( having been widely used at WDR by Stockhausen )

Fundamental leaves behind the limitations of the original device by proposing complex modulation possibilities, stochastic distributions addressing the sonic parameters like frequency , gain, stereo panning etc. in continuum, which has not been applicable until now.

Fundamental feels like something Stockhausen, Xenakis and HAL 9000 might have dreamed up after a bender: recalling the past of electronic music through a dynamic modern reinterpretation of a massive german vacuum oscillator,
