Un bon VCO "vintage" à super prix
БІРОЛ 07.11.2020
La gamme des modules Behringer est un excellent rapport/qualité prix pour démarrer dans le modulaire. Le 921 est simple d'utilisation et efficace, il sonne bien "vintage"... A ce prix là, c'est un VCO qu'il faut essayer!

EL
Works best for modulation
Earl Langoustine 20.01.2021
The Behringer 921 VC Oscillator is an accurate clone of the original Moog unit. Having used this module extensively, we've realized that it makes the most sense if used with the other Moog components. If you plug it into a typical Eurorack system, several things will probably confuse you at first.

- The switchable output comes with a switchable wave shape and a large volume knob, but also with an inverted output. This suggests that you are supposed to use it as an LFO, and use the inverted output to get saw and ramp. It will track with semitones, but it works a lot better in wide mode, where you can go to very slow up into audio rate, and can be used as modulation for very cosmic tones.

- The four waveform outputs along the bottom are much quieter than typical Eurorack level, but can be mixed together with the CP4 mixer (which also saturates). On the similar Moog 901 VCO, these outputs also had individual attenuation.

- Like the original Moog, the oscillator is tuned to F. The user should be ready to calibrate the tuning via trim pots on the back (see instructions in the manual, which is also online if it's not in the box)

- The oscillator tracks over a 5 octave range. Some of the waveforms like the sinus and triangle will lose their character at audio rate if you go too low. Also, the oscillator stops tracking pitch at 0 V, i.e. there is a minimum pitch when using this with CV.

- Pulse width ("rectangular width" here) only goes from 15% to 85% via the knob, but the full range of 0% .. 100% can be had using CV.

- "Clamping Point" is normally called Sync.

To better understand how the Moog modular is supposed to work, look up Daniel Fisher's Moog Model 10 videos. Also helpful is the AM Synths webpage about this module, which goes into much greater detail about this module's technical characteristics, voltages, et cetera!

A
Useless output levels (1/10th of normal eurorack levels)
Andvarc 04.11.2020
I bought this for use in my modular synth. On the surface it is a great oscillator for a bargain price. However, there is a caveat: The main waveform output levels are next to useless.

Raeson: The 4 main oscillators output levels are only -4dBu (0.48V rms). That is roughly equal to consumer level audio output (only 1/10th of normal eurorack levels). The aux output has a variable level and can output up to +/- 5V or rougly +16 dBu which is fine.

The low output level for the main waveforms means that you need to amplify these outputs by 20db to use them in your eurorack where 5V is the standard.
In practice what happens is that when using this module together with other oscillators and modules that output +/- 5V - the signal from the 921 is completely drowned out (unless they are amplified first - which is downright silly). Hence the only part of the oscillator you can really use is the aux output.

Ultimately I found this unacceptable and a waste of precious rack space and have returned the module. I am very sorry about that, because I loved the concept. Behringer: please fix this stupid design flaw.
