Yeah, I get that its not currently your business model.. but maybe something to consider / chat about with Dave.
I am happy with my Rev2 (and PEK and P12). You guys make really good synths... But there does seem to be a good amount of software/firmware possibilities that could take some of your instruments to next level status. I get that some stuff is not possible due to memory or processor restrictions, but some of it does seem possible, and just requires programmer resources.
I'm not sure if you guys follow what Fractal Audio is doing in the Guitar Modeling and FX area... but they really set a gold standard when it comes to continued development of their products. You "buy into" their Axe-FX II hardware unit, and you can pretty much expect that every month or two the unit will be significantly improved with new effects, new amp models, new modeling techniques and advanced options. Their founder and lead developer, Cliff Chase, is basically worshiped by the entire user base (Fractal Audio Forum), and if you look at their growth and adoption of artists, you see that they are completely changing the paradigm for guitar amp and effects sales. I don't know their financials, so can't say that their business model is the best out there, but it sure seems like it, when you see how fervent the user base is, and how every couple weeks they have new major artists endorsing them. (3/5 of best rock album Grammy noms are Fractal Audio endorsers)
Anyways, again, I'm a happy customer... would just love to see more software/firmware development and a philosophy of "leaving no stone unturned" in that realm... if its possible with the hardware architecture, find a way to make time resources to develop it,... and if you need to, just monetize it... I would happily pay for continued development of new features.
