The Behringer 921B Oscillator gives you an authentic reproduction of the circuitry from “Modular 55 and 35” series oscillators. So you’re able to build your own unique synthesizer that fits perfectly in a standard Eurorack case.
The 921B Oscillator Module is controlled by the 921A, but can also be used as a free-running LFO. Separate frequency and range knobs allow you to adjust the frequency range in semitones and also octaves. The 921B along with 921A modules form the foundation of a proper modular synthesizer.
Ins and Outs
What’s more, the 921B features independent audio outs for each of the 4 waveforms. Including sine, triangular, sawtooth, and rectangular. All of which can be patched out to different modules for even more creative possibilities. A dedicated oscillator sync input and switch can also be used to sync the 921B to a signal introduced in the Sync In jack. While parallel link jacks allow the 921B to link to another 921B in the chain.
921B – Eurorack Ready
Finally, the 921B Oscillator fits easily into a standard Eurorack case. Simply connect the power cables and screw in the module using the included screws.
