SKU: Radikal Tech -.RT-311 SWARM OSC Maker: Type:


A DSP based multi oscillator module with parameter snapshot interpolation

The RT-311 can store up to 8 memory setups with 8 snapshots each, saving all oscillator settings and memorizing them even after powering down your modular synth. One highlight of this module is the option to interpolate these parameter snaphots. Interpolation can be controlled by external control voltage or with a built in LFO. The speed of the internal LFO can be controlled by external control voltage as well. The interpolator even has an external output to interpolate one parameter of an attached module. Both oscillators can build swarms of oscillator clones. At the highest setting, up to 16 Oscillators are running simultaneously. The detune knob tunes the pitch of all oscillator clones between ultra slow oscillator frequency beating effects and multiple frequency drones and chords. The swarm can be pitched in musical intervals, chords, clusters or fat detunes. The swarm tuning can also be stored into the snapshots. That enables building up to 8 different chords with different sound settings one can change while playing in a setup.
The scale inputs can also get quantized to musical scales. This makes it easy to control the swarm from a step sequencer. Simply select the root key with the tune knob and a pentatonic scale and turn the knobs of your sequencer for always matching tonal sequences.
