I’d be surprised if there weren’t at least a couple of decent monophonic octavers (and maybe even a poly) in the unit but as we know, tastes in octavers can be very subjective/personal.
I personally doubt there will be a ground breaking synth engine in the Quad Cortex. Look at Darkglass/Neural products thus far: distortions, compressors, amps/cabs etc. but zero synth stuff.
The fact is, synth effects for guitar and bass are still a small niche area of the market and there’s a good chance that for Doug Castro and his team, building a comprehensive software synth engine to compete with the likes of Source Audio C4 and Future Impact simply isn’t worth the time and effort given the realistic impact on Quad Cortex sales at present.
Not saying it’s impossible but precedent tells me it’s very very unlikely, especially at launch. Quad Cortex has serious processing power under the hood though, so one can argue it would be foolish for the Neural folks not spend time creating some more ambitious effect types for the platform. Time will tell!
In the meantime, I’d happily stick a Source Audio C4 into one of the FX loops.
