PowerPC native code (mixing engine) can be enabled by adding the USE_PPC_POWERUP tooltype. WARNING: for best use of PowerPC code, you need: - the PowerUp kernel or - MorphOS The use of WarpOS (with PowerUp emulation) reduces ProStationAudio performances considerably, much below 060 speed. On most WarpOS systems, audio will not play without audible artifacts (stuttering). If you experience this problem you should: - boot with a different PowerPC kernel or - disable PowerPC code Questions? Email support for demo users: demo@audiolabs.it
