Synth Rorschach #48: MULTICS is ALIVE - booting MR12.6e 6180 emulation

Published on Feb 19, 2017 Redmartian

"This panel came from the University of Michigan and likely hasn't been driven this way in well over 20 years. Here we see the 6180 Multics emulator reading the switches set on the panel to 024000717200 and the initialize button been pressed to boot the virtual machine. The 6180 Maintenance Panel is being driven by a Xilinx BASYS3 which in run drives two logic boards that are cabled into the 6180 panel wiring harness. All switches and lamps are available to the emulator and you can dial through the scroll to check the various states of the machine. Once Multics has booted you'll see the famous Idle Pattern (or snake). Multics lives once again!"

Reminds me of Digisound meets EMS, meets something else I forget at the moment.

Analogue Solutions Raw Session - Oberkorn, Megacity, Nyborg-24, Nyborg-12

Published on Feb 19, 2017 rezfilter

"Here's another clip from a raw studio session featuring both Nyborgs (12,24), a little SE MidiMini as well as an SE p-five.

Nyborgs are being triggered and modulated via Oberkorn step sequencer. They have nailed the quirky-noise, percussion twinkles."

"Euphonics 1984" - Yamaha Rs-7000, Prophet 6, DW-8000, Minilogue

Published on Feb 19, 2017

"'Euphonics 1984'

Recorded live on February 14, 2017 using a Yamaha RS-7000 MIDI Sequencer and a room full of synths.
The original insipiration started with the Korg DW-8000 and its smooth sounding filter with a plucky guitar-like patch and two other patches. It made up the earliest parts of this piece. Later the Prophet '08 accompanied with brass pads. The Korg DW-6000 embelished melodies in the 4th part. The Novation BassStation II was responsible for all bass duties. 4 patches were used and a lot of automation was applied to modulate its volumes, filters and other parameters. The Art Tube Channel handled its dynamics with a tiny bit of eq. Later the Sequential Prophet 6 was added filling in various bits including melodic accompaniment and a delicious filtered sweep in the 4th part. The Sequential Prophet 6 had six patch changes and was used throughout the entire arrangement. The Electribe EMX played the vintage drum sounds and was assisted by various percussive noises on the Korg Radias and Roland XV-5080. The drum bus was ran through the Alesis 3630 Compressor. The Korg MS-2000 sang the vocal piece in the 1st part using its VOX oscillator mode and later played a high frequency patch in the final measures. The Korg Minilogue played several melodic parts throughout as well as some FX. The Roland JP-8080 played pads from beginning to end. The Roland Boutique JX-03 accompanied a number of melodic notes in the 1st, 2nd and 4th parts. A Mackie 1604-VLZ3 and a pair of racked line mixers connected everything including a number of compressors and outboard effects. The Art Pro VLA II had a lot to do with the overall sound. The video was shot with a Panasonic Lumix LX7 and was edited in Corel VideoStudio Ultimate x9.
