This tutorial will show you how to set parameters to a higher value than they were intended. For some reason the program can still read and actually render these values. This tutorial is made assuming you already know how to make and use vocal presets.
A text editor program (Like Notepad)
In order to be able to edit and use the parameters you need to make a vocal preset that you will edit.
If you want to edit vocal modes you are going to have to set a value to them. It doesn't matter what you set this value to. If you don't do this step then the vocal mode will not show and you won't be able to edit it.
Go to wherever your "Dreamtonics" folder is located. Mine was located in my Documents. Then open the "Synthesizer V Studio" folder
Inside of the "Synthesizer V Studio" folder you should be able to find and open the settings folder. Inside the settings folder you should open the "voice-presets.json" file in any text editor program. I'll be using Notepad.
*Optional
You don't have to, but I recommend saving a backup of the "voice-presets.json" file just in case you changed something and it broke everything. That shouldn't happen though as long as you don't delete anything.
Now that you have the file open you are going to need to find the preset that you made. If you are using Notepad you can press crt+f to open the "find" function. Enter the preset name and press "Find Next"
You can set any of these to any value. I do not recommend setting them below 0 though, it will probably break.
If you had vocal modes you can also set those values here as well.
Make sure you save the file before closing the text editor and open SynthV, if you already had SynthV open then you have to close and reopen it. Choose the voicebank you made the preset for and load it. The values will appear to be capped at its intended maximum value but it is actually set higher then that.
