YAMAHA released the Vitalise Unit (ELSU-V02 and ELSU-V02X) about a month ago.
However, it has proved so popular that they still don't have enough products to provide for the interested Japanese users.
In Japan, YAMAHA only sells this unit through their official Electone technicians with installation.
It is not being sold stand alone, only with a Yamaha technician installation.
The process to get just parts for international sale is still unclear.
With all of this said, we are still very excited to be able to say
We are expecting to get our first Vitalise unit in around September.
I assume we won't get the installation manual.
Once I recieve this item, we will start to make the "How to install the Vitalise Upgrade Unit on your 01 series Electone" in English.
It's gonna be around October or November before we can start selling this unit.
Until then, I can not provide much information for your inquiry regarding this item.
They alreay found a firmware issue between non Type U STAGEA with the Vitalise unit.
I guess it's good for us to wait a little bit more.
Thank you very much for your patience.
