Since around 2017 the Terpstra keyboard, now named the Lumatone keyboard is being made by Dyan Horvath in Toronto. Since 2019 Siemen Terpstra is making efforts to get paid for his author’s rights. He has made the design between 1980 and 1990. Up till now he has never received anything. Because of this we have to use the legal system and a specialized Attorney-at-Law. This is costing us a lot of money. For this reason we made crowdfunding in the form of a gift.

Siemen Terpstra does not have any money. He lives from the lowest income you can have in The Netherlands.

We hope to get support from everybody who bought a Lumatone Keyboard and/or anyone who wants to help. Every euro is a help to us. Also we want to make it clear how many Lumatones have been made till now. So if you have one we would like to hear of it. You can send an email directly to Siemen: info@siementerpstra.com If you have proof of buying one, like an invoice, it is much help to us. In this way we can make a list and check the correct amount of existing Lumatones.

We have a bank account for this: NL88ABNA 0418 8618 54. The BIC/SWIFT code is: ABNANL2A on the name: S. Terpstra.
