at risk of sounding very ignorant (I am!), what is the purpose of adding a dedicated audio interface such as Focusrite 2i4 in a Cantabile configuration? I’ve been using the sound card on my laptop (Toshiba Satellite Pro P755-S5390) to produce audio. The signal goes out of the headphone jack and into a small mixer/preamp, then on to our sound board (Presonus 16.0.2). I like using the WASAPI as my audio driver. No latency problems and in shared mode I can run Cantabile and Transcribe or VLC player at the same time.
My set up is used primarily for live gigging with my band. Keyboards are connected directly to the laptop via USB and are the only instruments I play.
Should I stick with what I’m using?
