The RS-380N Modulation Controller is a versatile utility module. It consists of a voltage controllable LFO with two waveforms, a sample & hold stage, white noise and a VCA. – A great combination for compact systems.
Thanks to its dual bus concept and a front panel with wide mounting holes, the RS-380N can be easily integrated in modular cases following either the Analog Systems or Doepfer standard.
The RS-380N is composed of the following circuits:
A low-frequency oscillator, which can generate triangle or rectangle waves. The LFO frequency can be adjusted manually plus there is a CV input. Via a switch, you can choose between two ranges:
- Low: 0.3 Hz to 6 Hz
- High: 5 Hz to 1500 Hz – Yes, the LFO goes way into the audible spectrum. Therefore, the circuit is well suited for FM experiments.
Via the already mentioned CV input, you can extend the frequency range even further. The LFO output features a level potentiometer.
An analog white noise generator.
Sample & Hold:
The S&H stage of the RS-380N is clocked by the LFO. Material to be sampled can be fed to the module via an input. Without a cable patched here, the noise generator is normalized to the S&H circuit.
A classic VCA with signal input, CV channel plus attenuator and two outputs.
Starting almost in parallel with Doepfer, Bob Williams established back in 1998 his own modular system with fine circuits reminiscent of the British tradition initiated with EMS in the 1970s. Despite offering initially a different power connector and panel width standard (which left a 1,5HP gap), all modules bearing the "N" on their names are adapted to work seamlessly with most eurorack cases. Still, it is worth checking the depth of your case.
