I just got the SYzd SE4, because I already had 1 and 2 and wanted some more vocal sounds, but I was somewhat taken aback by how poorly the vocal patches play in SE4. Like 80's synth voice sounds. But it was the programming of these patches not the recordings themselves, I found as I worked to crank them into something useful. I may as well share my presets with anyone here who has SE4 and wants to make use of the choirs and soloists...though the tenor soloist is still absolutely nuts sounding in the upper register lol.
I'm also including the SE1 Bosendorfer patch I uploaded a couple years ago, it tries to make the Bosey sound like the Synchron Steinway Lite they include in SE1, of course, with Bosey character. I also have it blend with the free Soft Imperial for a different flavor.
And also included, for anyone still using Vienna Smart Orchestra, I've programmed the missing bass-only presets. They include No Bass Instrument versions of the VSO patches, and they actually include the patches for Bass-only instruments, but they never provided playable presets for the bass-only instruments, so I've added them here without changing the keyswitches you're used to. This way you can have the contrabass do something else vs the cellos, write your bassline first, sketch with a freer hand.
These just unzip and go in Synchron Player Presets which is typically in your VSL folder in your Documents folder, then you find them at the bottom of your preset menu. Save a user preset of your own within the player if that folder doesn't exist yet. Public Domain, full disclaimers. Enjoy... Download "VSL Community Patches.zip"
