Home Keyboards ⇝ Yamaha ⇝ Yamaha PSR-48
The PortaSound PSR-48 uses the "DASSystem" which stands for Dual Architecture Synthesis System. When it was released, a keyboard based on waveform ROM was still a pretty new idea and Yamaha was in the process of transitioning from primarily using FM to using waveforms, so it included elements of both. It can be set to dual voice mode with two sounds playing at once. Polyphony is halved to 4 in that mode. The PSR-38 is a lower-end model with fewer rhythms.
