Looking for a “quadraphonic” LFO? Doepfer's A-147-5 Quad VCLFO delivers 4 interdependent triangle LFOs.
Doepfer's A-147-5 packs a simple but effective principle into ridiculous 4hp! A common frequency knob controls the fundamental frequency of all 4 LFOs. You can then use the ∆2, 3 and 4 controls to adjust the deviations of these LFOs from the first.
The ∆-parameters as well as the base frequency parameter are of course CV controllable, so nothing stands in the way of wild vibrations!
You want to modulate the pulse waves of your quadruple VCO? Or rather sum up all four LFOs in one mixer for a "super LFO"? No matter if quadrophonic modulations or as a simple 4-fold LFO: the A-147-5 finds a place in every system.
WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
