PlantsSystem-AD-X

video upload by plantssystem

"'AD-X' by PlantsSystem is a sonic work that weaves together analog pulse tones from the Prophet-5 and meticulously arranged noise through the tracker-based DAW Renoise. Eschewing a traditional beat, the piece constructs a weightless soundscape where pulsing electronics and finely textured noise engage in subtle dialogue. It's a quiet yet tense composition that rewards close listening, revealing delicate, experimental layers of sound.

Prophet X | Kawai K3 Sample/Patch bank| Out Now!

video upload by Espen Kraft

"The Kawai K3 from 1986 has always gone under the radar of many. Lush, fat, cold and gritty. It can do it all. It's digitally stored waveforms and analog SSM2204 filters.

The analog filters inside the Prophet X are modelled after the SSM2044 so this is a perfect match for these samples. I've made 32 custom preset patches on my Kawai K3m and focused on a variety of sounds that showcases the capabilities of the K3, yet being very musical and 'ready to go'.

I've then multi-sampled these into the Prophet X.

These are NOT velocity multi-sampled as I don't think that is necessary, but with programming of patches on the PX it's easy to do so authentically as the filters of the PX is almost identical of the real thing.

I've focused on strings, hybrid bells/pads, digital PPG type of sounds and a few basses.
Total filesize is around 550Mb.
All the multi-samples are also available as *sf2 (TAL sampler and Logic compatible) if you're interested. Price is the same.

The price for this pack is $22USD (or €20Euros if you're in Europe) and considering you'll get the absolute best K3 patches and samples directly onto your Prophet X, this price is a steal.

My CONTACT email address is this: espenkraft69@gmail.com
If you want to purchase this pack please send me an email and I'll give you instructions on how to order. If you want a bundled (discount) price for multiple packs just let me know.
I will only sell Prophet X packs directly through email.

I've included 20 patches to help you get going (I you can hear some of these in the video and my browsing through some of them) and you have two options of transfer: Bank U4 P78 – P100 or Bank A4 P00-P21. Both patch banks are included. If you want to transfer the patches SOMEWHERE ELSE on your own PX, you can do so manually, by editing the individual sysex files."

Details via NRSynth (Google translated)

Oberheim Legacy: In 1974, Tom Oberheim imagined a small synth as an accessory to his DS-2A digital sequencer. But it was Dennis P Collins, a gifted ARP engineer, who designed the multimode filter of the Synth Expander Module (SEM). This unique filter is a 12 db filter that cannot deny its lineage with the ARP 1047 (ARP 2500) and ARP 2023 (white Odyssey MK1) filters, 12 db filters also designed by Dennis P Collins. With two very fat VCOs and a devastating sync (also close to the Odyssey VCOs), the small SEM offers a powerful sound, very present in the mix and very different from Moog and other synths with 24 db filters. So despite its simplicity and a filter that does not enter self-oscillation, we can get a lot of sounds out of it. Accessible and easy to use, the SEM is a success. In 1975, Tom paired first two, then four, into a huge keyboard case, creating the first "true" polyphonic instrument in history, the "Four Voices." In 1976, the SEM was even expanded to eight. Nicknamed the "White Elephant," its sound was as enormous as the instrument itself! But in 1978, the brilliant Prophet-5 made it obsolete, and Tom designed the OB-X, whose channel cards were also clones of the SEM. Subsequently, the OB-XA and OB-8 used Curtis chipsets and no longer had quite the same sound. In 2010, Oberheim reissued the SEM identically, but with all surface-mount components. In 2011, the SEM PRO added just a MIDI interface.

NRsynth "Solo": This is an "extended" version of the SEM, handcrafted with traditional through-hole components. Only the envelopes have been modified for a punchier result; the rest is identical to the original synth. Additionally, the Solo features a sub-oscillator, a glide, white noise, and many more modulation options than the SEM. MIDI velocity is also supported. Finally, the white metal case gives way to a luxurious, classically crafted cabinet with waxed oak sides and black tolex, similar to a Marshall amp.

A patchbook of all Séraphin Palmeri's sounds is included with the device.

Specifications:

VCO: Two discrete VCOs with hard sync, saw, pulse + PW (same as SEM)
Sub-oscillator: Pulse wave – 1 octave below VCO1.
Noise: 100% analog white noise
Multimode 12 dB filter: Same as SEM with LPF, HPF, notch, and bandpass mode. VCA: Analog (same as SEM)
LFO: Analog, triangle wave (same as SEM)
Envelopes: Analog (same as Pro-1) with deactivatable "Release".
Digital LFO: 8 waveforms + tilt, 3 frequency ranges, sync.
Sample and Hold: Analog, sync.
Glide: Analog portamento circuit at the input.
Patchbay: 15 I/O points on 3.5mm jacks (Eurorack compatible).
Rear Connections: Audio I/O and sync on 6.35mm jacks. Reset button.
Dimensions: 30x24x15 cm

J3PO King Korg Neo Presets -- Official Sounds Demo

video upload by J3PO

"You can purchase the preset pack here:
https://www.julianpollack.com/shop
The introductory price is $29.

All FX (chorus, reverbs, delays, etc.) are coming from within the patches themselves i.e. there's no other external processing on this demo save for some slight light leveling/compression for the purpose of uploading to YouTube.

The King Korg Neo is an unexpected gem, challenging assumptions about what a compact, portable, digital synth can be. Its sound is both vibrant and complex, weaving warm, analog-like textures with modern digital tones that feel raw yet polished. With a bold 24-voice polyphony and versatile oscillators, the King Korg Neo manages to feel timeless and forward-looking, carrying an unmistakable authenticity.

Introducing the Sequential Prophet-10 Special Edition

Press release follows:

San Francisco, CA – [October, 22nd, 2024] – As part of the 50 Years of Sequential celebration, the renowned synthesizer company proudly announces the launch of the Prophet-10 Special Edition, a tribute to half a century of groundbreaking innovation in analog synthesis. This exclusive edition, with only 150 made, features exquisite lacewood panels that make each instrument a unique masterpiece.

The All-Natural Elegance of Lacewood
While the electronics are identical to the existing Prophet-10 Rev4, the Special Edition is distinguished by its stunning lacewood panels. Sourced from the lush forests of South America, lacewood is celebrated for its intricate grain patterns that create beautiful and varied designs. This exceptional wood not only enhances the visual allure of the Prophet-10 but also honors the long-held tradition of using fine woods in classic analog instruments.

A Collector's Dream
With only 150 in existence, the Prophet-10 Special Edition is a rare opportunity for discerning collectors. Each synthesizer comes with a certificate of authenticity, recording its specific serial number, and an embroidered dust cover, ensuring that this piece of musical history is preserved in pristine condition for decades to come.

The Return of a Legend
The Prophet-10 is Dave Smith’s ten-voice version of the analog poly synth that revolutionized the music world. Known for its warm, organic, and dynamic sound, the Prophet-10 combines all three revisions of the legendary Prophet-5 synth — Rev1, Rev2, and Rev3 — with a Rev switch that allows users to choose between the two distinct filter designs. The Prophet-10 Special Edition also includes the Vintage knob to fine tune instrument’s character, Poly Mod for wide timbral flexibility, and velocity sensitivity and aftertouch for new levels of expression beyond the 1970s Prophets, making it as versatile as it is powerful.

Experience the Prophet-10 Special Edition
Sequential invites professional musicians, collectors, and dedicated synth enthusiasts to experience the Prophet-10 Special Edition. This deeply organic lacewood edition is more than an instrument; it's a piece of history, a testament to Sequential's unwavering commitment to creating inspiring instruments for generations of artists.

"Even more of a classic than the OB-Xa, this beauty from around 1981 has been fully serviced in August 2024. It has a very unusual and useful mod where the cassette level switch is re-purposed as a noise switch and the filter can be multi-mode. ***More info: OB-X filter mod based on SEM. The mod uses the repurposed Noise buttons to choose LP/ Band/ HP Filters. Therefore patches can be saved with filter type setting. The noise modes are now accessible via the Cassette Monitor Switch. The new switch for cassette monitor is now mounted inside the synth. Considering the Memory Protect switch is already inside the synth and needs to be switched when loading patches from cassette (or these days a WAV), this new location is not an inconvenience. Most importantly the mods are all non-destructive and can be removed if desired. Also utilises the Magnetic RAM card so no battery is needed http://www.electrongate.com/dmxfiles/mram.html *** Very similar serial number (804109) to the Radiophonic Workshop OB-X, which was 804204. Unusual, really, to have the full eight voices from the factory, because the 6-voice seemed more affordable at the time and still beat the Prophet-5. The price in today's money would have been 16500GBP. Packing 30GBP to include a UK or Euro mains lead."
