Members mildbill Posted February 8, 2013 Members Share Posted February 8, 2013 Well, if it's not the DAC's that produce a change in sound quality, what would you all say is doing it? Link to comment Share on other sites More sharing options...
Members piano39 Posted February 8, 2013 Members Share Posted February 8, 2013 I don't know. I would like to try one out. I have a Motif XF and am a huge fan.It's possible that Yamaha compressed the XF waveforms to fit them on a cheaper board (less memory). Or they could have mucked with lower freq sample playback so that the processor doesn't have to work so hard. Also possible that the cheaper keyboard action on the MF tricks you into feeling that the keyboard is less expressive. Maybe somebody could A/B them on a high end oscilloscope to see if the waveforms differ. Link to comment Share on other sites More sharing options...
Members ElectricPuppy Posted February 8, 2013 Members Share Posted February 8, 2013 Compression. Smaller ROMs means they gotta crush the life out of the waveforms, and the best compression ratios are only had with lossy compression. Plus, if they can shave off having to process the highest-frequency stuff, they can use slower (read: cheaper) components. Link to comment Share on other sites More sharing options...
Members mildbill Posted February 12, 2013 Members Share Posted February 12, 2013 166MB - why compress? 8GB of flash ram is now $5.99 for the consumer here (probably about a buck apiece in the bulk quantities manufacturers use), and AFAIK flash ram used to be more expensive, .It doesn't make any sense unless they just want to intentionally compromise sound quality to protect their higher priced products.

Members AnotherScott Posted February 12, 2013 Members Share Posted February 12, 2013 They don't use flash, they use ROM. Typically, sounds cannot be executed directly from flash. (Or at least, not the cheap NAND flash you're talking about.) Link to comment Share on other sites More sharing options...
