ROLAND CR-78 RHYTHM DRUM MACHINE

images via this auction

I never noticed the sliders on the SH-32 are similar until now.

Auction description via wikipedia:
"The Roland CompuRhythm CR-78 is a drum machine launched in 1978.
Although primitive by today's standards, the CR-78 represented an important advance in drum machine technology at the time. The wood effect cabinet and preset rhythms of the CR-78 such as Waltz, Bossa Nova and Rhumba suggest that it was seen by its designers as primarily an accompaniment for an electric organ, but the CR-78 became one of the favorite instruments of New Wave and electronic musicians in the late 1970s and early 1980s. Songs that make prominent use of the Roland CR-78 include Heart of Glass by Blondie and In the Air Tonight by Phil Collins. [2]

The machine and its controls
The CR-78 used analog drum voices, which sounded very little like real percussion instruments, but they instead had their own distinctive sounds. The unit also incorporated an early Intel microprocessor to provide digital control of its functions.[3]

Previous Roland drum machines had offered only a selection of preset rhythms. The CR-78's key new feature was that in addition to offering 34 preset rhythms, it provided four programmable memory locations for storing patterns created by the user. These could be created by using step programming with the WS-1 box, which was available as an optional extra. [4]

EMS RANDOM VOLTAGE GENERATOR

images via this auction
"The EMS Range of Ancillary Studio Modules EMS Modules are designed not only for use with Synthi synthesisers but with any complex of voltage controlled equipment, of whatever manufacture. They are supplied in handsome afrormosia cases, but can be removed and mounted in standard 19" racks, occupying only 1.7" (44mm) of vertical space. They contain their own mains power unit with a very wide range of stabilisation to cope with poor mains line conditions, being operable at anything from +10% to more than—23% of nominal line voltage. Connections to and from the modules can be made either from the jack sockets on the front panel or via the multi-way socket at the back.

TWO VOLTAGE RANDOM GENERATOR [via tripod - click for more]
The EMS Random Voltage Generator produces a staircase type of output, the 'steps' of which occur randomly, but whose voltage range and time variance are controllable in the following ways:

Time: The internal clock which decides the mean rate of events can be (a) freerunning and subject only to manual control, (b) inhibited so that the next random voltage depends on a manual push button or an external pulse (equivalent to external clock control); (c) free-running but voltage controlled so that an external voltage influences the mean rate. In this state the device becomes a voltage/time converter.

If the time variance control is at zero, the mean rate is constant (though subject to change of steady rate if influenced by a control voltage). As the time variance control is tuned clockwise, the mean time random variance becomes greater, and when this control is at maximum the rate will randomly vary in a ratio of more than 100:1. The distribution of chances is rectangular, not Gaussian, so that no part of the variance range is particularly favoured.

Voltage: Two voltage outputs are available and separately adjustable, but both are subject to the same time control — i.e. the steps of the staircase occur at the same time from both outputs. At zero, there is no voltage variance at all, and as the setting is increased the variance about the mean voltage (set at the device being controlled) becomes greater, excursions being both positive and negative of the mean voltage. In addition, a trigger pulse is sent whenever a random selection is made, and a lamp on the panel glows at the same time.

The random voltage generator can be used for quasi-melodic purposes, for interesting timbre and other parametric changes, or at high speeds for randomly varying vibrato or tremolo (very near simulation of natural, performed vibrato), or for producing very dense textures of rapidly changing notes. A very versatile instrument, essential for any well-equipped electronic music studio.

SPECIFICATION
Power Supply:
240 or 115VAC 50/60Hz + 10% to —23%

Control Outputs:
+/- 2.5V max. (this excursion can be offset to accommodate non-EMS products).

Trigger Output:
+4V

Mean Time Range:
0.2 - 20 events per second.

Time Variance:
Max. approx. 100:1 (at mid-settings of mean rate — limited by possible clock range).

Select Input and Inhibit/Free Run Switch:
+ 5V at select input or manual push button operates and inhibits after one event if switch at INHIBIT. +5V will run clock at mean rate set while present at select input, if switch is to FREE RUN.

Voltage Controlled Mean Input:
0.5V/octave ( = doubling or halving rate) limited by possible clock range."

E.M.S. DIY Modular

via satamile on this electro-music.com thread where you'll find more links including a digital release.

"E.M.S. was a NY based Electro producer who actually made his own Modular, Drum Machines, Vocoder and a few other odds and ends. Out of this so far he has produced four Records on Satamile Records to world wide acclaim, being played by the likes of the late and great John Peel and Dave Clarke."

Arp Odyssey MKI with Patch Points

via Noisebug where it is currently for sale.

"Arp Odyssey Mk I (Model 2800). Has CV patch points and Oberheim filter. As the legendary first compact studio synthesizer, the Minimoog, proved to be a runaway success, ARP responded with a compact user-friendly studio synthesizer of their own with the Odyssey. Produced between 1972-74, these original white-faced Odysseys used a 2-pole VCF filter design (Model 4023) similar to old Oberheim SEM modules."

Malekko / Wiard Boogie Filter Episode 2 - Boogie Jam

YouTube via bigcitymusic bigcitymusic.com
"This filter sounds REAL good. Here's a fun one-note jam using the new Malekko Boogie filter. The Cwejman VC0-2RM is providing the drone while the Analogue Solutions Vostok is sequencing the Boogie's cutoff. Drums are provided by the crushing Jomox 888 with it's analog kick and snare.
We're sending the rim shot out, 1/8th notes, separately. That audio is being converted into a gate pulse by the Analogue Systems rs50, a very handy module, which is clocking the Vostok's sequencer. Danger high frequencies!"

Just a reminder, be sure to check out MATRIXSYNTH-C and the other sites in the header links above. I just put a video up from an electronic music performance in Costa Rica. According to Ernesto, the scene is growing there. Pretty cool.

Waldorf Microwave 1 Limited Mean Green Machine

via this auction
"You are looking at a Waldorf MicroWave, the original one with real analog filters and amplifiers. Actually, this is the limited edtion “Mean Green Machine” that was only produced 99 times worldwide. This unit has the number 43 and was treated as collector item.

The Mean Green Machine was produced 99 times when Waldorf announced the OS 2.0 for the Microwave. Needless to say, that this unit is updated to the newest OS available but it is also one of the later run of Waldorf Microwaves.

This practically is the PPG in a rack, with analog filters and amplifiers. 8 voices can be used in multimode with 4 individual outputs as well as a stereo pair outs. Wolfgang Palm himself did the hardware work on the Asic (Wavetable chip). Wavetable synthesis at its best, surely beats the newer MWII/XT series in raw power with 2 oscillators, analog 24db LP filter, analog amplifier with panning, 4 envelopes, 2 lfos, and flexible modulation routings.

The Waldorf Microwave “Mean Green Machine” Limited Editon comes with manual in pdf on CD, newest OS installed, and Step-up transformer (110V to 220V, 50 Watts). The power cord is attached to the unit."
