NAMM: Metasonix D-1000 - More Details


via Metasonix

"The first drum machine made with vacuum tubes since the Wurlitzer Sideman of 1959.

Unlike the Sideman, it's a "modern" primitive device--with plenty of inputs, outputs, and flexibility.

Even though it has only four drum sounds -- two tunable drums, a tunable "snare" drum (harder sounding than the others), and a cymbal -- control voltage inputs give great flexibility.

Each of the tunable drums is made from a vacuum tube ringing bandpass filter, and can be tuned to sound from below 20 Hz to over 2 kHz. They are also tunable with external control voltages, allowing complex patterns to be built up with external CV or pulse sources. Resonance of each filter circuit is set by internal trimpots. The cymbal sound is an extremely primitive circuit, with white noise gated by a pentode tube. The cymbal's attack is knob-variable and CV variable, from a sharp click to a soft "whoosh". The four outputs mix to a single tube preamp that allows for overdriving via the mix-level controls.

In keeping with the primitive nature of the soundmaking section, the pattern sequencer is extremely simple. Unlike early drumboxes, we won't subject you to preset nonsense like "waltz", "foxtrot", "swing" or the like. Instead, there is a single 8-pulse sequence with separate enable switches for each drum sound--set a toggle switch up to get the sound at that point, down for silence. Great for house, hardcore or other simple 4/4 patterns. The internal clock is settable from 60 BPM to over 1000 BPM. There is also a "roll" clock signal built-in, to generate a faster drumroll on any drum sound by pressing a button (speed is preset with an internal trimpot). If you don't like the internal sequencer, there are separate trigger inputs for each of the four sounds (the trigger pulse must be 0 to +5v, and less than 40 mS long). These trigger inputs operate in parallel with the built-in sequencer, so the D-1000's sounds may be triggered by its internal sequence and external pulses at the same time. As a bonus, the three tunable drums can also be used as tunable bandpass filters, by feeding a line audio signal to each trigger input.

Ample inputs and outputs: mix output (with overdriveable tube preamp), separate outputs for each drum sound, external trigger inputs for each drum sound, and a main clock output (0-5v) for slaving external generators to the internal clock.

No, it does not sound like a TR-606. It's a beast you have never seen or heard before.

Specifications: Inputs and outputs 1/8" jacks, except main mix output on 1/4" jack. Enclosed in rugged, moisture-resistant ABS utility box with hinged lid, carrying handle and latch. Size with lid closed 12.25"x7.4"x6.5" (314mmx186mmx168mm), weight (minus AC adapter) approx 3 lbs (2.1 kg). Power: 12-16 volts AC, 50/60 Hz, 1.5 amps. Uses Jameco 167151 AC adapter for power in 120v countries. Power inlet: 2.1mm coaxial jack."

TRIADEX Muse + Amplifier vintage sequencer synth


via this auction

"Extremly rare Triadex Muse and Triadex Ampifier module. Two rare pieces from '72. They are in perfect working and look conditions.

Without doubt, a nice piece for collectors and Music / Sound installation artists, search "Triadex Muse" on Youtube! The Triadex Muse is the first digital musical instrument and was produced in 1972. It was designed by Edward Fredkin and Marvin Minsky, the creator of the alien "MONOLITH" in 2001 SPACE ODYSSEY, friend & collaborator of Stanley Kubrick. Marvin Minsky has made many contributions to AI, cognitive psychology, mathematics, computational linguistics, robotics, and optics. In recent years he has worked chiefly on imparting to machines the human capacity for commonsense reasoning. His conception of human intellectual structure and function is presented in The Society of Mind (1987), which is also the title of the course he teaches at MIT. The Triadex Muse it's an algorithmic music generator: it uses digital logic circuits to produce a sequence of notes based on the settings of various parameters. It has four small sliders that control Volume, Tempo, Pitch, and Fine Pitch. It is not known how many were made, but they are considered extremely rare. For years, the Muse was a featured exhibit at the Museum of Science, Boston. The signage explained the device's algorithmic (and deterministic) approach to the creation of its seemingly-random music. Far from being random, its preset "song" played continuously -- and was even given a name, "Museum Musings," by the staff. USA standard voltage of 110 volts Shipping and packing costs to Europe are of 38 euro about. Spedizione e imballaggio in Italia: 14 euro circa"

EMS TKS Sequencer Keyboard for Synthi, VCS3 AKS


via this auction

"Extremly rare EMS TKS Sequencer Keyboard, 256 notes, similar to KS of the Synthi AKS suitcase. This is a very rare version for VCS3 mk2 or Synthi A with a very nice teak-type Danish looking wood cabinet. If you own a VCS3 MK1 old release, you can purchase an inexpensive power supply and modify a VCS3 jack to power the TKS."

ARP 1611 Analog Step Sequencer Anniversary Edition

via this auction

"Very rare ARP sequencer model 1611 anniversary edition. The difference with a normal 1611 are the 16 old school coloured leds down under the steps. It's a great sequencer, one of the best ever made in 70's, it's amazing for drive analog modular synthesizers and of course it is an inevitable part for ARP 2600 and Odyssey. I used it with a big RSF Kobol system...absolutely magic!"

Custom Korg Polysix


via this auction
"Every button, switch, knob, keys, input and output works on this keyboard. I have replaced the original battery about 1 year ago with a rechargeable battery pack as seen in the pictures and also cleaned all the key contacts at the same time. I have the original Polysix cassette, instruction manual and programming manual as well. The lit purple strip you see is EL tape that I added - I think it looks pretty cool but you can easily remove it if you want to."

Studio Electronics MidiMini

via this auction
"This has the MiniMoog Oscillator board, the Filter/VCA board and the Analog board! It is a full MiniMoog in a compact rack mounted unit with full Midi!! This particular unit was down to the fella's at Studio Electronics/Analogia about a year ago for a full tune up, latest OS installed and a 3-prong power cord added. SOUNDS AMAZING!!! The modification adds full Midi with velocity, aftertouch, pitch and modwheel setting, Oscillator sync, an LFO(so you don't have to use a Osc. 3 as an LFO), multi-trigger, sweepable second oscillator, note priority settings(last, low, high) and much, much more!!!"
