Drumcomputersystem Dynacord ADD-one/ADD-drive/BigBrain

the description is in German, here is the Googlish translation:

"In this auction to offer you a complete Dynacord Sampling drumcomputer System consisting of one ADD-ADD-drive (including the sampling option), and the Big Brain Sequencer. Who wants to know how the system sounds, should the first edition of the Synthesizer-Magazin care.

Dynacord ADD-one
The Dynacord ADD-one has a hammer in terms of sound, handling and editing. The Samplingdrumcomputer ADD-one was from June 1985 to February 1986 from a Dynacord cooperation with the American team of designers Froward Fast Design (former Oberheim). For example, the spring comes the legendary Oberheim Marix-12 and Xpander.

In 1987, the ADD-drive, a RAM with the motherboard has been extradited. This is one of the ADD-an external analog to digital input jack or XLR and a 3.5 "floppy drive to the external sample storage. Without this board RAM is the ADD-one with up to three sample-ROM Paltinen upgradeable.

Technical:
The ADD-one has eight Drehpotis under the 80-character LCD display. Here are the tools to input analog fashion, it can all editable parameters of a sample arranged on four menu page edit or you are screwed to a parameter for eight sounds simultaneously rum.

The ADD-one samples used as starting material for his sounds. Among the Samples are permanently installed next to bass drums, snares, congas, Hihat, etc. but also waveforms such as sine, triangle, pulse, miscellaneous
Noise and more. The samples have a resolution of 12 bits and a sampling rate of either
25 or 50 kHz. Each of the eight votes through the voltage-controlled, pure analog-based

Modules: filters, amplifiers and Panner. The filter seems to be a 24dB filter to be whose response to the self-sufficient. Modulates the filter as the resonance parameters, last but independently from the filter, through the first Envelope. The filter can also by the second envelope, and the resonance modulated by the LFO will. The samples are about the velocity of a MIDI keyboard in the volume variable. In addition to the panoramic position, the sample on the second envelope or LFO modulated.

Sound:
The ADD-one sounds just generally super gaudy. The slightly dull and a little accurate converter that time, brought it with him, that the attack and Trigger behavior of sounds and samples inaccurate and fails to even more violent. By synthesizer waveforms and analog filters by postprocessing and envelopes is one of the ADD to a normal analog synthesizer off Drum sounds. The layers of sounds allows extremely fat sound or braids Basses depths. Abert also for drum sounds from the genres of house and techno, hip hop, R & B or even
LoFi for the Group, there is no better tool.

Dynacord BIG BRAIN
Sequencer for the ADD-one or PERCUTER /-S. Gründsätzlich, the equation
BIG BRAIN + = ADD-one drum machine with all the trimmings "on.
Up to two PERCUTER / or ADD-S-one can move from one BIG BRAIN control.
Amazingly, the memory of BIG BRAIN: about two billion cycles!
There it is a 16-track sequencer, in addition to programmed rhythms as well as the dynamics could save.
With the combination of BIG BRAIN and ADD-times one gets a great drum machine.
Dynacord BIG BRAIN delivers not only MIDI clock, but also to DIN sync and therefore also works as a MIDI to DIN Sync converter. Of course all other sound generator through the control trigger outputs, eg in an analog modular synthesizer and environment.
BIG BRAIN is an extremely rare to find sequencer.
The program works similar to a Roland TR909: on LED indicators are simply the steps to the desired point in the cycle set.
They are triplets and shuffle pattern is very easy to use."
