The A-147-5 Quad VC LFO from Doepfer is a quad LFO with master frequency and triangle waveforms. Primarily, the module generates four cyclic control voltages whose timing is set with a master controller. If LFOs 2, 3 and 4 are to have a different frequency, this will always be in relation to the master frequency. This is very useful in polyphonic patches or to animate several parameters at once in large modules. The frequency range is from 0.025 Hz to 50 Hz, when modulated by another control voltage (keytracking, Velocity etc.) up to 150 Hz can be reached. With the CV inputs it behaves like with the frequency controls, they are always in relation to the master frequency.
