The second one was derived from a color mod i made of a Wusikstation skin, which was created by Synthpulse. This skin does also work with V1 of Wusikstation.
I love my Wusikstation, it’s a really versatile rompler with a huge sound library and good support from a very friendly developer. Also you can buy many addons for it from third party developers and currently a sale promo is running, where you can save 45% as a new customer.
