ARP 2600 Filter Modulation Patching

In this video, Meta Function demonstrate filter modulation patching on an ARP 2600.

The ARP 2600 is famous for providing the sound of R2D2 in the original Star Wars film, its heavy use on Stevie Wonder’s early material and providing the main riff on Underworld’s ‘Rez”. This is a V4.0 2600 released in 1974 and features ARP’s then new G-clef logo alongside the sort after Model 4012 filter (which was a copy of Moog’s patented ladder-filter design that eventually led to a legal dispute forcing ARP to design a new filter).

In this video a mix of saw and square waveshapes from oscillator one are run through the lowpass ladder filter. With oscillator 2 and 3 running as LFOs, various filter modulations are patched including Env 2, S&H, the Voltage Processor and the Electronic Switch. Due to the switching and voltage processes, interesting filter modulation can be heard as LFO 1 sine switches or inverts LFO 2 square.

Sequenced via a Sequentix Cirklon.

Audio recorded via Calrec S2 console and SSL convertors. All dry, no FX, EQ or compression. The only post production performed was normalization.

Watch at 1080p with good quality audio monitoring for the best experience.
