Do i need hardware 3D acceleration to use ardour, some raspberry pi type boards have no support for 3D acceleration but I was wondering if Ardour needs it
Ardour does not use or want or care about graphics acceleration.
While Ardour doesn’t care, an increasing amount of plugin UIs do use openGL. Then again a RPi doesn’t have much DSP power to use plugins to begin with.
Recent RPi-3b does however support openGL just fine, but it’s not enabled by default in Raspian.
