Today marks the first EigenD release on Windows with Alpha and Tau support, get it from the Eigenlabs download page.
It is built from the GPL source available on GitHub.
In conjunction with the 1.0.6 version of the Windows Driver, which you need to download separately from the Resources Page, it supports the Alpha and Tau instruments on Windows. At present, Audio support is limited to the Alpha’s Microphone. Headphone support for Alpha and Tau will be added in subsequent releases. You may still use older drivers for the Pico.
The EigenD 1.4 branch also sports a whole series of performance improvements that have been done while EigenD 1.3 is being stabilized. I personally have been using 1.4 for several months now and find it much lighter on CPU. So, Mac Eigenharpers, do give 1.4.1 a try!
