About 5 years ago I explored the synthesis capabilities of the Solaris by creating several sounds for it. Every now and then, I posted the presets at the user forum. Eventually John included them in the OS as factory preset bank 8. Frankly, I still feel honoured :) .
In case you own one of the later Solaris’, you should have the sounds on board already (Bank 8 preset 0 should read as »Softy«). If you don’t, here’s the files I sent to John on Feb 15, 2015.
