The ARP Solus is a light and portable synth that lies somewhere between the Axxe and the Odyssey. The Solus is monophonic with 2 oscillators that include pulse-width-modulation and a digital ring modulator. An FM slider allows for an external sound source to be ring modulated through VCO #1 which gives this synth added function as an analog ring modulator perfect for creating wacky sounds. A great sounding ARP VCF (filter) adds a nice touch. Pitch bending is accomplished using a simple knob. Designed for portability this synth comes packaged in a very nicely built road case. It has been used by Tangerine Dream.
