"Yeah, 5 years TubeOhm!
First a big “thank you” to all TubeOhm users for
their support for the 5 last years. We hope you have
had a good time with our Instruments. We are now
glad to present you Alpha-Ray, a VA synth including
special TubeOhm features. And the best, the full
version is free except the effect unit."
