Cracked Synthesizer V Studio Pro V 1.11.2
Yes you've heard that right 1.11.2 NOT 1.9

Yumekey seems to have been taken down, their practices are also quite shady so here's a version of their crack that actually works, no auth servers needed, Not the shady Synth V sharp that's floating around the internet.
First download any version of Synth V pro from this website The lastest version that works with it is 1.11.2
Download Obsidian here:
- Copy "obsidian.exe" and "obsidian.dll" to the Synthesizer V Studio Pro install path,
usually "C:\Program Files\Synthesizer V Studio Pro" or similar. - Optionally create "obsidian.ini" in that same path for configuration (see below).
- Use "obsidian.exe" to open Synthesizer V Studio Pro and install any voice database you want.
The voicebanks are also all available in this website. Just drag them into the window to install.
