"A resonant pad played with a lower cutoff filter. Applied some external shimmer and high frequency gain with my computer. Also, shamelessly stole a chord progression from a favorite band :)

The Orca Synth - A photocell light controlled digital synthesizer, played like a Theremin

video upload by LunaKraft Instruments

LunaKraft also made The Guitron I. Unfortunately the video there is no longer available, but you will find some pics.

"Digital music synthesizer created in the 'circuit bent' style, uses two photocell light sensors to create synth notes in any selectable key.

Each photocell controls notes for one voice of the synthesizer, each voice can be modified separately.
1. Octave control: selects 1-4 octaves for each voice.
2. Modulation effect control.
3. Control note length of each voice.
4. Waveforms: Square, Sine, Triangle, Ramp, Noise.
5. *Select 12 different keys.
6. A chorus effect.
7. Note pulse effect.

Some of the sounds remind me of the sonar sounds made by whales, hence the name Orca Synth."

Harmonic halls of noise - Prismatic Spray, norns “pixels”, 1010music lemondrop and TX-6

video upload by Arman Bohn

"The Prismatic Spray provides most of the sonic textures here. The notes it plays are controlled by a single pixel grooving along on the screen on the norns. The sound is then chopped up by the lemondrop and played back at various octaves. The Norns also provides five channels of sine wave drones. Everything is mixed in the TX-6.

You can pick up the Prismatic spray on my tindie shop:"

Studio Electronics Omega 8 sound creation

video upload by Ken Flux Pierce Fluxwithit

"Studio electronics Omega 8 is an 8 voice analog synth made with beautiful through hole hand built boards. This model has the stock Minimoog style ladder filters as well as the Oberheim SEM style state variable filters installed (sorry no CS80 , ARP, TB or Jupiter filters in here yet). It is a great joy to program and one of the last of the classic era of analog poly synths that can still be obtained today."

Paul T Schreiber of Synthtech / MOTM Retires From The Synth Business

"After 27 years, I have retired from the synthesizer business. I still have a #day_job which will last until Dec 1st. The last set of 16 modules shipped to Patchwerks in Seattle, including the last E520 Hyperions.

Is there a chance someone will buy my IP and continue the product like? I keep hoping. Thanks to everyone who were friends and customers."


The man behind MOTM and Synthtech/Synthesis Technology retires. Paul Schrieber was making modular synths in the MOTM 5U format before eurorack took off. He essentiall started his own format, 5U in height like Moog's MU 5U but different. See this old post for a pic of different modular formats. He made his modules available in both DIY and finished form. You all should be familiar with MOTM and Synthech if you are regulars of the site. If not, see the MOTM and Synthech labels for posts over the years.

Since the launch of this version of MATRIXSYNTH back in 2005, there have been a total of 831 MOTM posts, and roughly 367 Synthtech posts, including this one. I say roughly as there was another Synthtech that made the Chroma Cult - Rhodes Chroma MIDI Interface, that shares the Synthtech label I used to get the count. The first post to mention MOTM dates back to This EAR post on July 30, 2005, the second to MOTM Madness - Featuring Yamaha GX1 Filter clone on August 4, 2005. Sadly the mp3 linked there is gone. People let their sites go unfortunately. The first post to mention Synthtech is the Epic Son video by John L Rice from back on August 2, 2011. His designs also made it into non modular synths like this Studio Electronics Omega 8 w/ MOTM CS80 & 440 Filters.

Uno Synth Pro X vs TR-909: First Jam

video upload by Honeysmack

"First time play with the Uno Synth Pro X, and the only way I know is to test it with a banging Roland TR-909. All segments are recorded in a single take, no edits. All sounds are running into an Elektron Heat for a little warmth on the master bus. The Synth Pro X is pretty immediate to use and I'm yet to look at the manual. Does it sound like a 303, maybe yes and maybe no -- but there's so much more going on. Love the recordable automation and parameter locking, along with the superb delay and reverbs!! Thanks (grazie) to IK Multimedia for sending this to me to try out.

"Rave All Night - Sleep All Day!" - Hard, Minimal Eurorack Techno Jam

Recording Date: 08/13/2023
Tempo: 152bpm
Key: F minor

"This piece came about from the Hardware Jams Facebook Group's weekly challenge - which was....well, it's really a long story that has evolved over the last 3 weeks/challenges, lol - but it seems some TROLLS invaded last weeks' afterparty, and this week, we needed to jam FOR THE TROLLS for fear of being eaten! TROLLS like Techno, right?! "

John Bowen Solaris Gets An Update - v2.1 OS Adds New Functions to the Sequencer and Arpeggiator

via John Bowen Synth Design

"Here is my documentation describing the new functions in v2.1 OS for the sequencer and arpeggiator. I know many people don’t bother to 'read the manual', but in this case, I think it will really be of value. There’s some special applications of a few functions you need to know about, such as the ‘note pool’ used for random note values, or how the modulation paths work."

The images below are from the PDF documentation John shared with owners of the Solaris. You can click on the images to read. With four oscillators, vector joystick, classic analog models, wavetable synthesis, phase distortion, unique rotors, and a completely modular design, all running at 96 kHz for pristine audio quality, the Solaris remains one of the most powerful synthesizers to date.

SoftPop 2 in Session | Bastl x Casper | Noise Kitchen

video upload by NOISE KITCHEN

"Bastl Instruments x Casper Electronics' SoftPopII SP2 is live: 'a radical subtractive synth under the influence of unconventional digital control. It’s a rare beast that excels at both melody and noise in equal measure, ranging from bassline bangers, angelic chord progressions, distorted beats, and water droplets. It can even process inbound audio through the filter and VCA.'

Pretty words, but how does it actually sound in a live setting? In this video by Noise Kitchen staff Lotus Wash and Niels Aras we get right to it — two Bastl Instruments x Casper Electronics SoftPop SP2, one Eowave Quadrantid Swarm, one Moog DFAM, processed through Valhalla Supermassive, nothing else.

Over the 13 minutes multiple different dimensions of sound are explored, from punchy acid rollers and psychedelic slow-motion dancefloor beats, Niels Aras & Lotus Wash guide you through how the SoftPopII can be weaponised for the rave, away from the more ambient electronica applications of the synth heard elsewhere.

Filming & Editing by Adam Kořínek & Vít Linek — many thanks!"

Moog Grandmother & Classic Piano in Tschechien- Krizovy vrch- Kreuzgang Cvikov

video upload by musentriduse

"Inspired by this special beautiful place in Cvikov, Czech Republik, and the country and its people itself, I had the opportunity to compose this Song and this little movie in Travnic and Cvikov.
I hope you enjoy it, it's my first self-made production.
I play piano and Synthesizer in front of the Chapel on top of the Krizovy-mountain-'Kalvarienberg' (in German)it is shortly after a Thunderstorm, the rain was still dropping from the leaves of the so old trees.

'Kreuzberg' or 'Kreuzweg' means a place where the crucifixion of Jesus Christus is showed in life size 3dimensional frame-pictures to lead to a chapel on top of the hill, where the grave of Christ is imagined. There are 14 Chapels with different pictures."

Yamaha SY-2 SN 3081

via this auction

"Super organic, extremely expressive, warm sounding synthesizer.

It could basically be viewed as a sort of single-voice CS-80.

Those two filters are rather amazing !

In a very good condition.

Included are the original upper case lid, chrome legs, and chrome sheetmusic stand (which is often missing for some reason).

A few flaws:

- Due to age,the filter sliders exhibit some static while beeing moved

(I wonder if there are any SY-2's out there without it - this is my 4th one and the 3 before all had the same to various degrees).

Rherefore, some cleaning might be needed.

- At the bottom of the synth, the compartment holding the power cord is missing a small metal piece, which is used to open the door.

Now a small screwdriver or something similar is needed.

Just minor flaws, but should be mentioned anyway, of course.

Thanks for looking, have a great day ! :-)"

MiniMod 6U Full System Stereo Filter Patch with the Gemini 2412 Dual SEM-based Eurorack VCF

video upload by AJH Synth Official

"Stereo filtering example using the MiniMod 6U Full System, now available to purchase from, pre-installed in a powered case. This patch takes a mono (monaural/not stereo) sound and creates the impression of stereo movement by using the Gemini as 2 separate filters, with their own output VCA, and panned hard left and right in the mix. Each filter affects the incoming audio in opposition to the other, under the control of a single LFO to determine the 'panning' speed. Rather than panning volume levels, it is altering the frequencies allowed to pass through the filter to each VCA (side), but the results can be far more interesting than simple audio level modulation.
Another example of what is possible using just this single, modest-sized case, packed with an incredibly flexible, vintage-voiced, fully analogue, Eurorack modular synthesizer.
For a more detailed, step-by-step guide to using the Gemini 2412 as a stereo filter, and some more example sounds, see this earlier video, which also features a downloadable patch sheet: [posted here] The AJH SYNTH Eurorack range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.

Sound comparison of Lofi-12 and Lofi-6

video upload by SONICWARE

[Japanese translation of the narration]
Lofi-6はLofi-12のサンプリング・レートを6kHzに変えただけの製品ではありません。 それぞれの製品コンセプトは異なり、サウンド・エンジンも異なります。






"Lofi-6 is not just Lofi-12 with 6kHz sampling rate. Each product concept is different and the sound engine is also different.

As you know, Lofi-12 is the point of sound alias noise that occurs in digital recording.

Lofi-6, on the other hand, was developed with the aim of producing the sound that came from old analog gear. In the Lofi-6, each track is specially processed to suppress digital alias noise.
For this process, I had to cut the hum effect of the cassette tape simulator.

Also, in order to reserve resources for the tube amp simulator mode on the Lofi-6, the 12bit sampler mode on each track of the Lofi-12 has been removed.

Now listen to the actual sound. "

East Beast Patching With Bata

video uploads by Bata

"Grabbed the West Pest a few weeks ago and was quite happy with it so decided to try it's sibling as well. Overall I think it's good although the way some of the knobs are scaled is a little peculiar and hard to use. Setting the right amount of vibrato or a subtle attack amount can be quite tricky even for experienced synth rats. The filter, oscillator, and VCA all sound really good though. Audio-rate modulation of the VCO pulse width and vca level sound particularly good on this synth."
