In the early 70s, the first System 55, 35, and 15 synth modules hit the market. They were super expensive back then because op - amps cost a fortune, so most had discrete transistor designs. This discrete circuitry gave these modules a unique sound that graced the records of legends like Keith Emerson, Stevie Wonder, and Tangerine Dream. Modular synths were a big step in electronic music, and now it's getting even better! The 921B VCO module offers a vintage sound from the 70s. You can control it via the 921A OSCILLATOR DRIVE module or use it as a free - running LFO. It authentically reproduces the circuitry of the 'Modular 55 & 35' Series. Many famous pop, rock, and jazz musicians have used it. There are separate audio outs for sine, triangular, sawtooth, and rectangular waveforms. It has a dedicated oscillator sync input with a switch for strong or weak sync. Parallel link jacks connect frequency and width to 921A and multiple 921B Oscillators. The frequency and width jacks can also be external I/O for more creativity. It follows Eurorack specs: 8 HP, 30 mA +12 V, 45 mA -12 V.
Using this Behringer 921B Oscillator Eurorack Module is a breeze. First, if you want to control it, connect it to the 921A OSCILLATOR DRIVE module. Or, you can just let it run freely as an LFO. When it comes to getting different sounds, use the separate audio outs for each of the four waveforms - sine, triangular, sawtooth, and rectangular. For syncing, use the dedicated oscillator sync input and switch between strong or weak sync as you like. You can connect multiple 921B Oscillators or the 921A using the parallel link jacks for frequency and width. And don't forget, you can use the frequency and width jacks for external input or output to get more creative. As for maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. When not in use, turn it off properly. If you have any issues, refer to the official Behringer documentation or contact their support team.
