"Although many vintage synth websites describe the functionality of Solus as lying somewhere between the Axxe and Odyssey-- the Solus being a dual oscillator monosynth with osc sync and ring modulation, I'd say it's sound capabilities are much closer to the Odyssey. Like nearly all Arps, the Solus VCOs, VCF, VCA, and Env are all derived from 2600 and Odyssey designs. Being the last monosynth Arp created, the Solus is probably one of the most stable Arps insofar as tuning and scaling.

the sound is distinctly vintage and raw, bright and buzzy like an Oddy. The Solus is almost exactly the same size as an Odyssey and is essentially just missing the Odyssey's S+H and AR Generator. It also adds a few features not on the Odyssey, such as continuously variable waveforms (on both osc.s) and reversed envelope modulation to the VCF. The other major difference between the two is the build design of the Solus; Being built into a highly portable tolexed suitcase, this design makes it extremely useful as a performance instrument, or as a portable studio kit. It's relatively light, and includes most every feature you would want on a professional synth kit such as Portamento, VCO Frequency Modulation (FM), Pulse Width, Pulse Width Modulation, Oscillator Sync, External Audio Input, Ring Modulator, 24db VCF, LFO triggerable ADSR (auto-trig), etc. There's much more functionality here than what you find on a Moog Prodigy or Rogue or even Roland SH. It's much more comparable to an Odyssey or MS20. The Solus also has a fair amount of Modularity with both Inputs and Outputs for Gate, Trigger, and Pitch CV; There's also an Audio Input and a CV/Expression Pedal Input to control VCF Cutoff Frequency and/or VCO 2 Frequency."
