I already requested this in the Cubase section. Steinberg’s own SpectraLayers has supported WASAPI (in addition to ASIO) since 2020, or even earlier. So I wonder if it was possible to port the WASAPI code to Wavelab, too? Sometimes there is a legitimate need to listen to and/or record multiple sources in different apps under Windows at the same time. ASIO is not very well suited for that, and Steinberg’s “Generic Low Latency ASIO Driver” is, unfortunately, practically unusable. Most competing contemporary DAWs support WASAPI. Thanks for considering this.
