Wonder how good the emulation is compared to some of the other commercial solutions out there. Usually software implementations of this hardware don't sound right
I just played around with it and the emulation isn't bad. What's really missing is any way to mute/solo instruments. Without that, you can't even do an ad-hoc performance. The instruments have been stripped down to their bare capabilities and are not even close to a full recreation, UI changes aside. And of course there is no way to save/load sequences or settings. And I found several bugs where certain parameters didn't seem to work or toggling one thing changed the parameters of something completely unrelated.
So for anyone who dabbles in these instruments, it's a fun toy for about 5 minutes and that's it. I suspect you can't expect anything more out of a promotional piece.
The TR-808 and TB-303 sound pretty good to me. I was in an electronic rock/pop/avant garde trio throughout the 80s and we used those two devices (and a Sequential Circuits Pro One) a lot. I still have pattern notes I could use to reproduce our old patterns with these emulations. They sound pretty close to me, though you have to allow for the unreliability of memory.
I always look for how the filters sounds with Res set really high. Good analog filters have a sort of fuzzy quality to them, which I suspect (not an EE here, just guessing) is extra harmonics from how that circuit behaves under those conditions. A lot of software emulations just sound thin, this included.
I'm not an authority on the 303, though. I just like to play around with analog gear sometimes.
I did SO much with Rebirth-338 back in the day. Its emulation wasn't so bad.
I've tried getting it to run on Windows 10, but even after all the hacks I could find online, it just doesn't run quite right. It was made in the era of 800x600 resolutions. And even though there's a pixel-doubling patch available, it looks like hot garbage.
Even still, this was a huge part of my music experimentation phase of life. (My youth)
I played with Rebirth on and off pretty much since it's been around and my opinion is that its sound is an homage to the real 303, at best. The spirit is certainly there but it's hard to make Rebirth sound exactly like a real 303 or hardware clones. I haven't played with any of the newer (as in, made in the last 15 years or so) 303 software implementations but I would suspect most of them are more faithful recreations.
The original 16-bit version will run in Wine without any additional patching, but I'm not sure what options that would give you for resolution problems.
So for anyone who dabbles in these instruments, it's a fun toy for about 5 minutes and that's it. I suspect you can't expect anything more out of a promotional piece.
