This might seem like a funny title until I explain a little history about Kemper. For many years Mr Kemper was responsible for a hugely successful synthesizer the Access Virus. There have been a number of iterations of this synth but it currently retails as the Access Virus TI2. TI stands for total integration - namely that the synth is completely integrated with a computer via a plugin window and the audio is transmitted via USB. This synth is everywhere in popular music. Look it up!
So what? You say..... Well Access have abandoned owners of the Virus by not bothering to update the software. As a result the synth doesn't work with any Mac with a Catalina onwards OS. Despite numerous requests from owners to continue to support the synth (which is still for sale new) Access has gone quiet for several years. Many people now own a £2K piece of abandonware. So be warned Kemper Profiler owners. Don't expect to be treated any differently when it suits Access/Kemper to ditch you because it is convenient for the company.
