Roughly 100 presets using the samples from the Muz3um soundset which can be found here:
Please make sure to install the Muz3um soundset before using these patches.
I don't encounter any issue with it. Nothing abnormal after six months of use. Either in the wavetable synthesis either in the sample reading, even with very big samples and the six layers used. Have you sent reports of issues to the Cakewalk support?
Rapture Pro is NLA, but you can still get Rapture if you have a Cakewalk Account (Signup not possible anymore), the code from a Computer Music issue from 2014 can still be redeemed. The GUI is small, but it's still a very capable synth. Definitely worth the 5 dollars I paid for it.
