Thanks guys. I am using ASIO drivers and have tried the input monitoring, but there is no response in the tuner interface.

The VST Host software can also not make it work, at least not right away, but maybe the problem is a kind of setup. I will read the manual, write to Polytune and maybe install a demoversion of a DAW software, which is tested with the product. I guess neither of them are free:

– Cubase (Mac/PC)
– Pro Tools (Mac/PC)
– GarageBand (Mac)
– Logic Pro (Mac)
– Ableton Live (Mac/PC)
– Studio One (Mac/PC)
– Reaper (Mac/PC)
– WaveLab (PC)
– Sonar Platinum (PC)
– Bitwig Studio (MAC/PC)
