>Also DX7 had sampling rate of 49096 Hz, 12-bit "floating-point" DACs etc etc. Note that the output wasn't 12-bit. There was a 12-bit DAC chip, but additionally to those 12 bits there are additional bits that are fed to another DAC (implemented using resistors) in charge of doing "gain-ranging" (that is, adjusting the output level of that channel). Thus the dynamic range available was much higher than just 12-bit. >Most of software versions of DX7 don't take these nuances in account which makes some DX7 purists upset. If you, as a DX7 clone developer, want to make happy these 2 or 3 people too, please, use fixed point calculations, resampling, real ROM data and so on :) On the other hand, i play the hardware DX7 (the real thing) plus a DX7IIFD, and i'd rather have the developers produce a cleaner version of the DX7, with a much larger/longer sine table, and more nuances to the sound. On the 'net, many claim the DX1 and DX5 sounded much more cleaner (not just "less background noise" but "sweeter sound"); i wish we could aim for that.
