Hi this is a tough one , I have Acid Pro 8 it works with VST 3 , I also have a trial version of the new Rythmizer plugin vst (link below) . I have got the plugin to work a few times but although I can see the signal is going in from my soft synth to the Rythmizer it is silent although sometimes it works ?, I think its to do with midi routing and monitoring but its past my skills in setting up , p.s any previous posts about vsts I have got working now even the VT3's. Hopefully someone out there will help as Magix have said they wont me help even though I upgraded to Acid 10 but it was faulty and they refunded me. Thanks in advance :) Link --- https://futurephonic.co.uk/item/rhythmizer-free-demo
