Tensai rhythm machine, 80s boombox with drum machine

via this auction

"This is a really odd item, can't find any info about it online!?

So what i can tell you is: it's a 1980's boombox with built in analogue drum machine!

I've recorded the output here so you can get an idea of the presets:
http://soundcloud.com/maily/tensai-rhythm-machine

This device can also be used as a 2 track recorder, featuring a guitar and mic inputs.

I think this could make the basis of a really interesting circuit bend or just a super unique addition to the collection of a drum machine/ 1980's/ analogue recording enthusiast.

More photos here"

Update: some additional info via Jan:

"this boombox was also distributed in Germany under the "Lehnert" brand and was called the "Lehnert Studio-5000". My parents bought one in 1978 or 1979, I can't remember exactly. I tried to find more information about it and the company in the web a while ago, but alas no success. And my mother threw hers away some years ago…

More pics on [via this auction]

Judging from the German labeling with the correct Umlaut usage, and the more detailed description of the device's functionality on the lower left of the German front panel (compared to the English Tensai version), I assume that "Lehnert" might be the original (German? Austrian?) manufacturer.

More pics of the machine's guts: [link]

On [link] you can see the manufacturing date of the tape motor is 1977.

The 2 way speaker system sounded really nice, the rhythm section allowed pressing multiple buttons simultaneously to combine rhythms, the external input allowed to use it as an amp for my first synthesizers (Casio VL-Tone and Korg MS-20), and you could use is as a limited 2 track recorder. I had a lot of fun with it 30 years ago."

Mutable Instruments Shruthi 1

"Here Is a Mutable Instruments Shruthi 1 Analog synthesizer kit. It has been hand built by a professional and has the latest firmware. This synthesizer is a monster! With all analog filters and envelopes with digital waveforms it makes for the perfect synthesizer. The OS is constantly being upgraded, adding new features and better performance. These are very hard to get, as they only make about 30 of them every 3-6 months. This has the included case and will be ready to play when you receive it in the mail. Buying this kit from me is a great decision because if you do not have the time or the skills to make it, you can be assured to still get a quality build without potentially damaging the kit.

"Fitted with pitch control, distortion, M-Z3R0 death industrial delay circuit with filter, rate and feedback controls, pitch LFO with rate and depth control and atari punk console square wave oscillator.

Modified to the extreme, this beast can kick out an unlimited amount of glitching, noise and mayhem.

it has loads of internal sounds which can be mashed up with the embedded circuitry i've added as well as merged with the APC square wave for dual oscillator tones.

I've used one of these for some time to create hundreds of drum samples and bizarre incidental sounds.

This is a machine you'll have a lot of time for whenever you require something a bit crazy to drop into your tracks. You could pull off an entire power electronics set using this machine alone.

Don't be fooled by it's cute appearance. Make no mistake, these things are beasts :)"

Synthesis Technology MOTM E560 Deflector Shield

via this auction

"Overview
The E560 is another unique DSP-based module that has no equal in the modular world, in any format.

It is a triple-mode effects module: thru-zero frequency shifter, phaser and ring mod. What sets the E560 apart from other DSP effect modules is the unique carrier wave morphing feature. Traditional frequency shifters and phasers use sine waves as the carrier/modulator, but the E560 has 8 different carrier waves (sine, triangle, square, saw, 16-point random phase, 64-point random phase, cross-modulated triangle/pulse and 3x sine) that can be continuously cross-faded to create never-before heard soundscapes. The 8 carriers are specifically selected to give the widest sonic palette, from simple frequency shifts to 64-note ‘pattern sequences’ to extreme harmonic content.

Technical details
SHIFT: a frequency shifter than can shift thru-zero with 2 simultaneous outputs (DOWN and UP). Like traditional frequency shifters, a sine carrier will generate a smooth shift but the E560’s 7 other waves will generate a vast array of harmonic content and even patterns of evolving timbral shift.

RM: a standard ring modulator (4-quadrant multiplying VCA) with a twist: the 2 outputs are always forced into quadrature (90 degree phase shift). The 8 carriers can produce everything from tremolo effects to gating to high degrees of distortion.

PHASE: this is an E560 exclusive mode. The audio input is applied to an 8-stage all-pass network. The 2 audio outputs are in quadrature, but in turn phase shifted from 0 to 360 degrees relative to the input. Not only that, the ‘vector’ the phase shift follows is the data in the carrier wavetable. The phase shifting can be linear (saw wave), traditional (triangle) or bouncing all over the place (64-random phase waveform).

Not only do you have full control over the effect, but also the wet/dry mix and applying either positive or phase-inverted (negative) feedback. This introduces peaking at certain harmonics or cancellation of those harmonics. Applying a slow LFO to the Feedback CV can produce a wide range of constantly changing spectral content.

Measures and weight
3U Eurorack module.
Module width 14HP (70.8mm)
Module depth 32.5mm
current draw: 110mA (90mA @+12V line and 20mA @ -12V line)"

Creating the Enjoy the Silence (Depeche Mode) bass line via Oberkorn MK3 and Telemark Synthesizer

YouTube Uploaded by rezfilter on Mar 27, 2011

"...by request!

*Watch in HQ for best video/audio quality!

Here's a recreation of the classic bass line from Depeche Mode's "Enjoy the Silence" (Violator!) using DM-style methodologies.

By utilising a step sequencer and a flexible analogue synth (Analogue Solutions Oberkorn & Telemark respectively), you can produce the moving / transitional effects inherent in a complex bass sequence such as this one.

Given the timing of the pattern, the Oberkorn was MIDI-stepped manually (see Midi-Stepping an Analogue Sequencer video for more information) and the pitch transposition was handled via MIDI as well. Alternatively, the pitch could be played live via MIDI.

The key is to take advantage of the precise opening and closing of the filter via Oberkorn CVB.

All settings will ultimately be approximate, as analogue synths will differ from machine to machine. Use the settings as starting points and then tweak away!

Enjoy (the Silence)."

Switches on the right of the machine are used for Damage and Crash Sounds & for creating new instrument patches from corrupted versions of the original patches.

Snow Fall - EMS VCS3 Filter Clone

via AMSynths

AM8071 Module - "Snowfall" Diode Low Pass Filter

"During the exceptionally snowy weeks of early 2010 I built a redesigned version of this classic filter which was used in the EMS VCS3 and AKS synthesizers in the 1970’s. With snow falling and the wonderful bubbly sound of the filter, I named this module - Snow Fall. It was a 4-pole diode ladder low pass filter using all discrete and rather old components. The Roland SH-3 filter (AM8003) and PE Minisonic 2 (AM8050) filters are close copies of this legendary design.

EMS originally (in 1970) described the filter as Low Pass and with a cutoff rate 12dB for the first octave and then 18dB per octave thereafter, with band pass filter response at medium Resonance levels and a maximum Q of 20. From early 1974 EMS updated the filter with an extra capacitor at the base of the diode ladder to provide a steeper 24dB per octave response, this appears to have changed the character of the filter. The filter frequency response is stated as 5Hz to 10kHz.

In terms of electronic design the standard filter is 4-pole but the characteristics of diode ladders makes this sound more like 18dB, and the 24dB version is really 5-pole. No matter, the filter sounds fantastic....
