Secrets to Steve Porcaro’s Sound: The CS-80 & More
video upload by Anthony Marinelli Music
"In this episode, I hang with Steve Porcaro for an up-close, hands-on look at the secrets behind his sound, with Toto and much more! Discover the musical thinking that shaped some of the most iconic synthesizer moments in pop history.
You’ll watch Steve perform on the legendary Yamaha CS-80, and demonstrate exactly why its polyphonic aftertouch changed everything. He shows how touch, phrasing, and pressure become part of the music itself, then recreates the iconic Africa brass sound, breaking down how it was programmed and performing it right before our eyes. We also pause to honor David L. Abell and Clark Spangler, two essential figures in synthesizer history whose whose work helped bring instruments like the CS-80 into the spotlight
Along the way, Steve shares stories from working with David Paich and David Foster, and how his collaborations shaped their sound. You’ll also see a beautiful portamento and glissando demonstration tied to "After the Love Has Gone" by Earth, Wind & Fire and 'Serious Music' by Hall & Oates, revealing how Steve approached expressive movement on the keyboard.
Steve then breaks open his 'go-to' CS-80 panel settings and shows how he used them on 'Rosanna' and 'Mama' by Toto, offering a rare look at the real-world musical decisions behind those songs.
Finally, Steve and I talk about the true secret sauce behind so many signature songs from the ’80s and ’90s, from Toto and beyond—the attention to detail, musical sensitivity, and collaboration between specialists, all working selflessly in service of a great song.
This is a rare, in-the-room masterclass with one of the great musical minds of our time."
Buchla Tiptop Audio 258t + 259t FM Patch | Percussive / Wooden Textures
video upload by VoxModula Archives
"A non-spoken modular patch performance focused on FM percussive and wooden-like textures, created using the Buchla TipTop Audio 258t and 259t oscillators.
In this session, frequency modulation is used to shape short, transient-rich sounds that resemble struck wood and organic percussive elements.
The patch is fully improvised and recorded live, no post-processing.
🎛️ Modules used
• 258t Oscillator
• 259t Oscillator
• 292t Quad Lowpass Gate
• 245t Sequential Voltage Source
• 266t Source of Uncertainty
• Buchla / Tiptop modular system
🎧 What’s explored
• FM techniques for percussive sound design
• Wooden / organic timbres
• Transient shaping and dynamics
• Live modular performance"
HWJ - Another 2 Box Jam (rough draft)
video upload by SynthAddict
"Osmose and RC-505
A rough sketch, submitted as is and is the essence of a live HWJ.
Live elements played into a looper, and no going back.
Needed another take but lost track of time... had to upload for the deadline."

"Features and Specifications:
Input: 1/4" Input
Input Sensitivity: 3 volts peak-to-peak maximum
Portamento: Minimum to maximum travel time
Output: CV Out Hertz/Volt Analog Pitch Control (0 ~ +8V)
Output: CV Out Octave/Volt Analog Pitch Control (+1 ~ +5V)
Output: Trigger High to Ground
Output: Trigger Ground to High (+15v)
Modes: 3 Levels of Tracking Response
Range: High and Low range of operation
Output: Envelope Control Voltage
Dimensions: 283 mm (W) x 195 mm (D) x 110 mm (H)
Weight: 2.4 kg, 4W
In the late nineteen seventies, Korg was apparently determined to open the world of synthesizers to more than just keyboard players.
Introduced in 1979 just a year after the classic MS-10 and MS-20 the MS-03 converts incoming audio signals into a range of control voltage signals. The MS-03 can drive just about any monophonic analog synthesizer, with outputs that support both the Moog/Arp/Eurorack standard of one volt per octave, and the less common Korg/Yamaha standard of hertz to volts. The unit also has two different types of gate outputs.
For users of the Moog/Arp/Eurorack standard there is a tuning and width control. The tune control is used to "tune" the MS-20 to the attached synth, and the "width" control adjust the precise range of one octave.
Korg MS-20: The circuitry of the MS-03 is similar to the Pitch to Voltage circuit in the Korg MS-20, but a comparison of the two converters shows the MS-03 is faster and more accurate than the MS-20.
Korg MS-03: The MS-03 has many of the same controls as found on the Korg X911 Guitar Synthesizer without the synthesizer components. Features found on both units include footswitch-operated Portamento, Synthesizer "Hold" and "Cancel" functions.
[Condition]
This MS-03 is in perfect working condition and in Very Good condition.
This unit was checked by professional technician.

Soma Messeiver - Shortwave based ambiant musical instrument

You can find a demo previously posted here.
"From the SOMA website:
MESSEIVER is an irrational device for exploring the world of primal, wild radio reception – the way it was first experienced by the pioneers of radiocommunication.
MESSEIVER – is a shortwave receiver that is capable of receiving different stations from all around the Earth. Its peculiarity is that it doesn’t have the classic input tuning circuit, which lets you select a single station. Instead, it captures a big part of radio ether as it is. This way you can listen to many radio stations at once from around the globe. The set of stations that you can hear, their loudness and sound are defined by numbers of constantly changing global natural parameters. Weather, solar activity, cosmic particles, clouds and dozens of other phenomena define radio waves propagation, turning the world into a global DJ that makes a unique mix of radio stations here and now, exclusively for you. More details you can find in the manual and demo video.
MESSEIVER has a luxury vintage handmade build with brass inlay, wide range old school speaker, custom coil, NOS germanium diodes, vintage neon bulb and other things which make the impression and vibes of it unique."
