Kawai K5000 — The Legendary Additive Synthesizer From The 90s

video upload by RetroSound

"Welcome to this demo of the legendary Kawai K5000 — one of the most advanced and unique digital synthesizers of the 1990s.

Released by Kawai Musical Instruments in 1996, the K5000 series became famous for bringing true additive synthesis into a hardware synthesizer with an incredibly deep sound engine and expressive realtime control.

Unlike traditional subtractive synths, the K5000 builds sounds from up to 128 individual harmonics, allowing for evolving textures, shimmering pads, vocal-like formants, metallic atmospheres, and complex cinematic soundscapes that still sound futuristic today.

One of its most iconic features is the powerful formant filter, capable of creating animated spectral movement and organic vocal-style timbres rarely heard in hardware synthesizers.

The K5000 was available in several versions including the K5000S, K5000R, and K5000W workstation, and over the years it has gained cult status among ambient artists, soundtrack composers, experimental musicians, and lovers of deep digital synthesis.

In this video you’ll hear original patches, evolving additive textures, classic 90s digital atmospheres and some factory demo and promotion tracks made the K5000 one of the most underrated synthesizers ever created.
I used the K5000 in the years 1998 - 2010."

Oberheim OB-12 Community Archive

The OBERHEIM OB-12 Community Archive is a new site dedicated the to Viscount Oberheim OB-12. It's an extremely well done site. Be sure to take a look.

It includes:

"Everything known to exist online for the Viscount-made virtual analog (2000), gathered here in one place, free."

via the creator of the site:

"I thought it might be of interest to MatrixSynth readers because it includes something the OB-12 community had wanted for two decades: the official Viscount Service Manual with full schematics (49 pages, 2001), recovered and now freely available, along with the CPU datasheet, every firmware version, the OB12Editor for Win98/ME, manuals, sound banks, the Jexus patches and the press reviews mirrored offline."

1/14/26 Simmons SDS6 + TAMA DS200 + Alesis MIDIVERB II + CXM 1978

video upload by Cfpp0

"This is one of two videos I recorded for the great Alex Ball (‪@AlexBallMusic‬) to use in his video about the history of drum synthesizers. I’m using the Simmons SDS7 to trigger the two halves of the TAMA DS200, with reverbs from the Alesis MIDIVERB II and the CXM 1978. The DS200 is running hot through the MIDIVERB II, overloading the preamp. The CXM 1978 has a long predelay in lo-fi mode to create a grainy pitchy echo."

"New Uses for Old Circuits is a series looking at linear and nonlinear processes in the modular system.

In this video we explore the relationship between continuous and discrete signals, and observe how playing with that tension in the context of a feedback loop leads to chaotic behavior.

"A minimal dub techno piece created with Game Boy, FMS, LSDj, and ‪@KORG_INC‬ wavestate.

On the wavestate, the arpeggiator is enabled while the sound is continuously shaped and transformed using knobs and the stick controller.

On the Game Boy Advance, FMS is used to play glitch noise and FM synth phrases.

On the Game Boy, LSDj is used to create rhythms based on TR-909 and 808 style kits.

Each device is matched only by BPM, without wired synchronization."
