Tips & tricks

Future development plans


FilterOrgan is developed by Blt, a freelance developer and hobby musician from Hungary. He publishes his works under the name BltWorks. In 2017 he established a startup to be able to sell his software officially.

(OK, I'll switch to first-person, I suppose everyone suspects that this is me who is writing it anyway.)

It all started in my childhood when we got a C64 (***Instant love with programming!***). Later, on PC, I started to experiment with music-related ideas, and thanks to the feedback regarding one of my projects I realised that I should switch to a multi-platform development environment. So I started to learn C++ and JUCE, and for practicing I chose one of my earlier projects to rewrite it. It was FilterOrgan.
