Hi Tommy,
as far as I know, it is as follows:
You only need to import a License key (.
n25) to the Tyros4 if you want to install Premium Packs. (A Tyros4 Premium Pack is a FOLDER with the extension ".YP2" in the folder name.)
To import
Custom Voices (.
uvn/.
uvd format), with or without using a Custom Voice Library file (.
uvi), a License key is NOT needed.
The normal way to get such a License key is (was):
- On your Tyros4, you have to export the Instrument ID (.n26) and upload this file to the Yamaha MusicSoft website. (The Tyros4 must be registered at the Yamaha site before.)
- Based on your Instrument ID, Yamaha creates a personal License key for you.
- You have to download and to install this License key file (.n25) on your T4.
- Then you can purchase Premium Packs and install it on your T4.
- According to Yamaha's advice, purchased Premium Packs only work if your personal License key originally received from Yamaha is installed on the T4.
You can download a License key file (.n25) here and test it with your T4. But I'm afraid it will NOT work as expected in your case ...
