the number of gets is reduced on the playback buffer therefore reducin' the CPU load for reads durin' playback of all trax except those in record mode. the ADC still takes care of timing playback. the old/current way places a HUGE load on the entire session because the record/playback buffers are the same. so if you have 100 trax all at 32 buffer the gets and puts are workin' their azzes off. reduce the gets for reads and your cpu load goes down...a lot!!! make sense??? maybe???
