AWM (Advanced Wave Memory) sampling uses digital technology to record an acoustic instrument's sound. AWM Stereo Sampling creates a deeper, richer and more spacious sound by using pairs of waveforms (L and R) captured with two microphones. Just as on a traditional acoustic piano, the keys of the lower notes have a heavier touch while the higher ones are more responsive to lighter playing. The keyboard's sensitivity can even be adjusted to match your playing style. This Graded Hammer technology allows this lightweight instrument to provide an authentic touch. the P-35 has a slim, contemporary and compact design. This allows for both easier storage and portability in a wide range of applications.
