Behringer 1004 Oscillator

For some, the ARP 2500 is probably the holy grail of synthesizer history. Definitely rare, extremely impressive in terms of its dimensions, overwhelming in terms of sound and, then as now, a one-off. The dinosaur of analog synthesizers, built from 1970 to 1981, looks very tidy despite its modularity, which is thanks to the crossbar system used. Behringer has reduced the modules to the compact Eurorack format and meticulously adhered to the historical originals in terms of both function and sound.

The Behringer Oscillator 1004 is a clone of the tone generator of the same name from the ARP 2500 synthesizer. The outstanding feature of this analog oscillator is the mixable waveforms. By means of five toggle switches, each of which is assigned to a waveform, all waveforms can be combined as desired, even all at the same time if required. In the center position, the waveform is switched off. The audio range extends over a range of 15.5 Hz - 16 kHz, in LFO mode 0.03 Hz to 32 Hz are achieved. The pulse width of the square waveform can be modulated. There are also two FM inputs with attenuators.
