Thank you for your inquiry.
Sorry, ASIO Plugin is only compatible with HARK 2.x.
There are plans to release it in the 3.x series, but it is not supported at this time.
If you really want to use ASIO, I’m sorry to trouble you, but I would like to use it with the HARK 2.x series.
2.x series can be downloaded from here.
Please note that the required tool version is different from the 3.x series.
