ARP Little Brother
The Little Brother is an expansion module for any ARP-System monophonic or polyphonic synthesizer. It has its own built-in VCO oscillator and LFO. Use it to double up your monophonic Axxe or really fatten up the sound of an Odyssey, 2500 or 2600! The LFO can add really new and cool modulation effects to these synths too! Best of all several Little Brothers can be stacked to greatly expand or enhance the functionality of your ARP synths in a modular-like fashion! Though the Little Brother uses ARP's System Interface for interfacing with these other synths, it has CV, gate and trigger inputs and an LFO out as well.
