Buchla Thunder + ASM Hydrasynth | Noise Improvisation
video upload by Ryan Gaston
"I recently took delivery of a vintage Buchla Thunder—a MIDI controller I've been dorking out over for years. In this video, I'm exploring a tiny bit of what it can do when combined with an ASM Hydrasynth desktop module...in the form of a mostly noisy/textural improvisation. (Note—the laptop is there purely for the sake of recording. All sounds and effects are coming from the Hydrasynth.)
Released in ~1990, Thunder is bonkers. Like many of Buchla's prior instruments, it uses touch-sensitive plates as a way of interacting with electronic sound engines. There's no "default" setup...you have to program everything that it does from scratch. It can translate touch directly into MIDI notes, or your touches can be used to initiate/conditionally influence programmed strings of events. Keys can even be used to conditionally modify one another's behavior—it's very deep, and things can become complex quite quickly. That's much of its charm: it's very easy for simple interactions to unwind into complex, unexpected flurries of sound.
So it's quite powerful...but given that I've had it for only a short time, I'm still barely scratching the surface. That said, it's already proving to be super inspiring to play, and I'm excited to keep digging in from here."
How to Make Edgar Winter's Frankenstein on Synth
video upload by Anthony Marinelli Music
"In this ghoulishly delightful episode, I'l be dressed in my Halloween finest to transport you to the creepy and kooky labratory of "Young Frankenstein." Our set is adorned with all the trappings of the classic film, setting the perfect ambiance for an up-close breakdown of the iconic synthesizer sounds of Edgar Winter. You'll experience my frightfully-fun re-creation of the mind-blowing synthesizer wizardry that made this song a legendary rock anthem.
With my ARP 2600, I'll unravel the supernatural secrets behind this iconic track. From spine-chilling synth leads to thunderous bass lines, to the iconic "Frankenstein Sound" coming to life, you'll be forever enchanted!
I've also included pumpkin patch sheets for 6 of the sound effects in this video along with the transcribed lead solo. Go to AnthonyMarinelliMusic"
MPG-70 Patch Generator Bass Category
video upload by Retroaktiv Synthesizers
"Some BASS patches generated by MPG-70 patch generator. Sorry for the flickering of the OLED. That's due to the camera refresh rate. In person, the OLED has no flicker and appears solid white. These are tricky to shoot due to the refresh rate of the OLED vs the refresh rate of the camera."

"This vintage ARP Odyssey has just been fully serviced in October 2023 by Synthchaser, the top ARP specialist - recapped, new key bushings, all new LED sliders, fully functional, tuned and calibrated, and sounding awesome! The Odyssey was ARP's answer to the Minimoog, a feature packed scaled down version of the legendary ARP 2600.
A video functional demonstration of this synth that is for sale is at the end of the pictures list.
The synth is in great condition. This synth comes with illuminated LED sliders that correspond to the colors of the original slider caps. I can disable the illumination for the buyer before shipping, upon request at the time of purchase.
Work just completed on the synth included:
Synthchaser Precision LED slider upgrade - All 34 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement. LEDs run off their own power supply mounted inside the synth.
Illuminated slider caps - Slider caps with a translucent plastic stripe that allows the LED illumination to shine through, while giving you something substantial to grip onto. They look and feel awesome!
Power supply rebuilt - All tantalum and electrolytic capacitors in the power supply have been replaced, and high quality, high temperature 105 deg C capacitors have been used for the power supply filter capacitors.
All tantalum capacitors replaced - The tantalum capacitors in ARP synths are ticking time bombs.All tantalum capacitors in this synth have been replaced with electrolytics to help provide stable operation for years to come.
Synthchaser 4023 Voltage Controlled Filter Submodule - This is a very fat 2 pole dual OTA filter. Synthchaser modules are true to the original designs and professionally built using premium components with superior performance and reliability to those found in the original modules.
Keyboard rebuild - New key bushings installed, keys removed and ultrasonically cleaned, bus bars removed and polished, bellcrank caps cleaned and lubricated.
Oscilloscope calibration - Calibrated & tuned using oscilloscope and frequency counter.
1/4" output made High - ARPs of this era had an RCA jack as the high output and the 1/4" jack as the low output. As today RCA jacks are an inconvenience for most, the 1/4" jack has been made to a second high output.

"Access Virus TI2 Polar synthesizer. Synthesizer is like new, it was bought but not used, just kept in storage. There is no damage or scratches on keys or on casing. All keys and knobs work like they should. LCD screen still has plastic wrap on it.
Operating system has been upgraded to the latest version (5.1.7.00). I tested its functionality (local mode, multi mode, sequencer mode) and USB connectivity with software DAW, everything works like it should."

[demo] Old-School Poly Sounds (Quantum/Iridium)
video upload by Synthesizer Video Service
"These are all 100 patches from my new Waldorf Quantum and Iridium sound bank in one go. This package is called 'Classic Poly Layers' and it contains pure VA sounds ('Waveform' oscillator model) for these awesome machines. Of course, all patches use mod-wheel and aftertouch.
The best: these patches are perfect for layering. Just put two of these sounds on both layers of the Quantum or Iridium to create a fat and complex sound. This way, you can create 10,000 (100 x 100) new and exciting combinations!
I modeled these sounds after a well-known synth from around 1980, but I won't say which one to dodge criticism. But maybe you can guess which one it is. It would make me happy in any case. Feel free to post your guess in the comments!
Here you get a continuous mix of all patches, recorded directly onto three DAW tracks, without additional hardware or software effect processing - just pure Quantum MK1 (only internal effects)!
Get these sounds in the shop (EU only): https://www.frequture.net/shop/"
Roland GAIA 2 - Custom patches

"Here's an update on my custom patches I've made on my GAIA 2. So far I can say this digital synthesizer is a success thanks to the hands on and way more flexible modulation."
Lofi-12 XT [Explore the capabilities of 24kHz sampling]
