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."

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.

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."

ERICA SYNTHS HEXDRUMS 09 // LØSTLVLS


video upload by LØSTLVLS

"A slightly dirtier HexDrums workout today, this time with the Master drive gain all the way down but at 100% for a slight definition boost. I think this is my favourite setting. Definitely makes things sound hairier without going into mangled territory.

Apologies for when my head gets in the way of the camera - will attempt to stay further back in the future. :)

Check out my sample packs on Bandcamp - loads of vintage and modern gear (leaning towards drum machines) with kits, sample chains and presets. All ethically-sourced and locally-grown here in the lab in Bristol, UK: https://lostlvls.bandcamp.com/"

Mos-lab & Scrotum Lab "The 2500 adventure"


video upload by batchas

"I skipped the part about making my matrix and the all process which took weeks and weeks behind the choice of pins instead of switches, but I might come back to it and do a video next year. Time will tell. Meanwhile here I'm looking back at the nice and positive moments I had with this 2500 clone, from receiving the modules up to the latest patch I did this year."
