"The Kawai K5m is a late-80s rackmount digital synth that uses additive synthesis to create complex, evolving sounds from many harmonics. Its very powerful, known for shimmering, metallic textures and deep sound design potential.
Could be that studio sleeper you’ve been looking for. Tested in great working condition overall with mild rack rash."

KORG LAMBDA ES-50 48-Key Polyphonic Analog Synthesizer SN 230602
Note: links to listings are affiliate links for which the site may be compensated.
via this eBay listing
"For the uninitiated, the Lambda is a fully polyphonic keyboard, brass and string synthesizer with two sections: Percussive (Pianos, Harmonics and Clav) and Ensemble (Brass, Organ Chorus and Strings). The sounds from these sections can be used in any combination and output together in mono or stereo.
The chorus phase effect is rich and sounds great when using the Lambda in stereo. The effect can be set to either or both the Percussive and Ensemble sections and its speed can be controlled with the joy stick. A pair of tuning controls allow you establish the range of the chorus phase, from minimal to lush to seasick.
Everything on the Lambda works as it should and sounds excellent. All the jacks work as well. The expression jack uses a control voltage pedal, not a standard expression pedal. I’ve used an Expressive Touché controller with this (set for 0–5 volts as required for the Lambda), and the keyboard responds with volume changes accordingly.
The sliders work fine, with no noise or stiffness. All the controls turn and function as they should."

Tempest ：アナログの咆哮とリズムの肉体性(2022.03.20) from X
video upload by Suzuki Ryo
"なるリズムマシンを超えた「楽器」としてのTempestの記録です。
OSの不安定さや、アナログ回路ゆえの気難しさはありますが、それすらもねじ伏せて音を紡ぐ瞬間の緊張感がこのアーカイブには宿っています。 特に、フィルターを絞り込んだ時の低域の粘りや、スライダー操作による有機的な音色の変化は、デジタルでは決して再現できない「肉体的な響き」そのものです。
最近、過去のアーカイブをじっくりと聴いてくださる方が増えており、驚きとともに大きな励みになっています。この動画も、そうした音の質感に耳を澄ませてくれる方々へ届くことを願っています。

• 断片的な記憶とProphet X：雨音のデュレイ・グルーヴ
*Beyond a drum machine: A record of the Tempest as a true 'instrument.'*
Despite its notorious OS instability and the inherent temperamental nature of its analog circuitry, there is a distinct tension in this archive—the feeling of wrestling with the machine to weave a sonic narrative.
The visceral 'stickiness' of the low-end when the filters are tightened, and the organic tonal shifts driven by the sliders, produce a raw, physical resonance that digital synthesis can never truly replicate.
I’m surprised and deeply encouraged to see so many people taking the time to explore my past archives recently. I hope this video reaches those who appreciate the subtle, living textures of sound."
