With all due respect to the dev team, just how big of a need is there for this? In the universe of things the devs could spend energy on (including things to generate new revenue streams), redux does not seem compelling to me.
Who needs another sampler this day in age? The big guys like kontakt and halion are already cross-platform. For some of the niche sound design stuff, there’s shortcircuit (although frankly kontakt can do that stuff too if you invest enough time in it). Okay, so there’s a sliver of a market of OSX/inux people who want a sc port. The MPC-heads have their choice of bpm, geist, and poise. I recall there was a point where discoDSP was giving highlife away for free and still couldn’t get people to adopt it. Arguably there’s also hybrid synth stuff like alchemy. There’s linux users who aren’t using renoise but that’s a pretty small niche too.
You need a really really compelling new sampling paradigm to make a dent in this space. Renoise instruments are cool, but I don’t know if they reach that bar - personally, the main reason I use renoise instruments for sampling at all is because they’re integrated in an awesome tracker.
PS I say this as someone who really likes the R3 beta.
