OP-1 Deep Dive #2 | Pulse synth engine

video upload by Oblivion Corner

"The Pulse synth on the Teenage Engineering OP-1 synthesizer is described as being a "dual pulsetrain oscillator". This OP1 synth engine works primarily by allowing you to change the distance between the two pulses that form the oscillator. Additionally, a one knob filter, amplitude and modulation control round out the sound shaping options available on this OP-1 synth engine.

Roland Jupiter 8 w/ Kenton Midi Kit & Flight Case SN 030117

via this auction

Additional SYNTH CITY Listings

"This Jupiter 8 is in great working condition and was just serviced and calibrated.

New Kenton midi kit freshly installed, pro job by our in-house tech. However, the previous owner attempted the midi mod and hacked out the rear panel in the process (hence the large metal plate and missing ROLAND logo). DCB port has also been removed.

Cosmetically the synth is in very good condition despite the rear panel. The keys are in great shape and are very white. All buttons are functioning fine and it sounds incredible as usual!

Includes original manual and flight case."

Crumar Bit99 61-Key Programmable Polyphonic Analog Synthesizer

via this auction, also on Reverb

"Black Crumar Bit-99 with a lovely lovely filter sound. All works as it should. The right panel looks like it took a hit at some point, and a key was replaced along the way (see pictures). The exterior is aged but looks pretty good as it’s not a gloss black finish.

Upper and Lower functionality works great, although Upper channel is louder. This may be able to be adjusted by internal trimpots."

"Well, not quite the usual I suppose. Always loved the sound of the saxophone but never got one, alas. In junior high I wanted French and the flute or sax, but they gave me Spanish and the baritone horn. And I suppose that explains everything, ya know? But hey, now we have iPad software! And iFretless Sax sounds pretty amazing. I also have iFretless Brass, used here as well, and iFretless Bass, which to me feels very Chapman Stick-like, which I love. They also have a guitar app but I haven't tried that one yet for some reason. So one day I had an electric piano going in SnakeBud and I was just sitting there playing "sax" and from out of nowhere, or wherever the music comes from, Remembered arrived. Add a synth wash, as usual, and a shimmered trumpet, et voilà, we now have jazz. Or something.

And as always, I thought the video edit wouldn't be a big deal, but somehow every time I think that it's just more and more ridiculous. Which is why I used that screen as the thumbnail for the video. To celebrate it, of course.

This one is sort of both how-to and also music, so again, not quite the usual as more often it's either one or the other. But today it's both. And also, putting together the "stuff used" list for something that sounded like it was "simply" using just four instruments, it somehow turned out to be, well, rather lengthy.

Remembered: 02:22
Very fast hardware setup: 08:28

Wavefonix W314 First Jam & 1847 Wavetable VCDO Sound Demo

video upload by Molten Music Technology

"Just got the W314 from Wavefonix plugged in and here's a recording of my first patch. The two 3340 oscillators are being sequenced by the Wavefonix 8-Step Sequencer and the Wavetable oscillator is getting two notes from a Varigate 4+ (both off-camera). There's some reverb on the output module. Otherwise, it's all the W314. More to explore!"

Wavefonix 1847 Wavetable VCDO sound demo

video upload by Molten Music Technology

"The 1847 module is part of Wavefonix's W314 Eurorack system and here's a handful of minutes of moving knobs and enjoying the sorts of sounds it produces. There are 16 waveforms in the main oscillator with 8 in the sub-oscillator over 4 octaves. The main oscillator morphs whereas the sub switches which gives it an interestingly different effect when modulated."

Runningonair - Sometimes (Music Video)

video upload by Runningonair

New bitterweet track by supporting member, Runningonair.

Warning! Adult Language included!

I started this project as a demo for the Wasp synthesizer, but as usual it developed into a full blown track. It's inspired by some of the darker emotions, those moment where someone says just the wrong thing and pushes exactly the right button. I've include Fortnite footage, which often inspires strong feels and meltdowns. Seemed appropriate.

FAST FPGA Audio Signal Processor Demo

video upload by Romain Michon

"This system was designed as part of the FAST project ( and provides a round-trip audio latency inferior to 80us. The various elements of the user interface also have a low latency of 100us."

"What is FAST?
Embedded systems for audio and multimedia are increasingly used in the arts and culture (e.g., interactive systems, musical instruments, virtual and augmented reality, artistic creation tools, etc.). They are typically based on a CPU (Central Processing Unit) which limits their computational power and induces some latency. FPGAs (Field Programmable Gate Arrays) can be seen as a solution to these problems. However, these types of chips are extremely complex to program, making them largely inaccessible to musicians, digital artists and makers communities. The goal of the FAST project is to enable high-level programming of FPGA-based platforms for multichannel ultra-low-latency audio processing using the Faust programming language (a standard in the field of computer music). We plan to use this system for various applications ranging from sound synthesis and processing to active sound control and artificial sound field/room acoustics."

SYNTH-WERK Introduces SW 1630 BODE FREQUENCY SHIFTER & SW 735 Rack Version


"After long and intensive research & development work we are very proud to announce our newest creation, the SW 1630 & 735 BODE FREQUENCY SHIFTER. The first batch of 10 units is already build and sold to our friends from the waiting list.

From today on the Module is available and can be ordered.


SW 735 rack version: 2.150 Euro plus TAX"

A frequency shifter is an audio signal modifier which shifts the entire frequency spectrum of the applied signal by a given amount. The Model SW 1630 Bode Frequency Shifter allows the amount of shift to be accurately and continuously controlled over a span of -5000 Hz to +5000 Hz, utilizing voltage and/or manual control. The relationship between the control voltage sum and the amount of shift may be either linear or exponential. Up-shifted and down-shifted outputs, as well as a continuously variable mixture of the two, are available simultaneously and independently. Variable threshold squelch and zeroadjust fine tuning controls are provided.

The Model SW 1630 Bode Frequency Shifter changes the ratios between the frequency components of an audio spectrum, thus producing a variety of novel sound quality transformations. Applications include a wide variety of tone color modification, P.A. feedback suppression, linear frequency modulation, novel tape feedback effects, and the generation of dynamically varying clangorous tones.

In shifting the components of the input audio spectrum by a given amount, the SW 1630 Bode Frequency Shifter changes the original ratios between the overtones and other frequency components of the input signal. Rather than being a transposing device, this instrument is a means for achieving an extremely wide variety of tone color modification. Whether the amount of frequency shift is large or small, static or time varying, or whether the input signal is simple or complex, the processed outputs will generally be musically interesting."

X1L3 - UWX - underwurlde glitch expander - eurorack module - demo track.

video upload by X1L3

"Demo tune featuring underwurlde and uwx expander.

When in stock - available at:

Pretend AGA Amiga pixelated demoscene-alike outing with track put together by manually manipulating the UW and UWX. Main loop is a sequence put together by grabbing slices of shard. Melodic section is then trashed for the mid section and a vocal grab is torn up before the main loop kicks back in for the outro. Tune does the talking, scroller elaborates on that, story reel - just eye candy for the sake of it really.

UWX is a 4hp module that adds the extra five glitches that are standard on the desk top version of underwurlde. A compromise was made when the main module was created due to space and I/O limitations. By removing the jumpers from the back of UW and plugging in the UWX to the pin header with the supplied ribbon cable you can access all eight points of the glitch array. You get a year zero art is resistance flag on the front panel intersection thrown in when you do this too :D"
