AW: AW: [Digital_Hell] DX-7 Noise

Juergen Haible asked:

<<Did they build a new chipset for the SY / TG series ?
If so, did they increase the word length, compared to
the DX / TX series ?  >>

The original DX7, TX7, and TX816 all had 12-bit DAC's.  The subsequent models
(DX7-II, DX7s, and TX802) had 16-bit DAC's.  I imagine that they also had
larger word lengths to take advantage of the larger DAC's.  They certainly are
cleaner and less distorted sounding than the original units, especially on
sounds with low modulation indexes (mellow sine-like sounds, etc.)

The later models in the series (SY77, SY99, TG77) also were 16-bit.

In case you guys haven't yet heard, Yamaha has two new FM instruments coming
out at this time.  One of them is the FS1r, which appears to be a kind of
combination of FM and additive technologies (imagine a cross between a highly
expanded type of Yamaha FM and a Kawai K5000, probably with multimode digital
filters and lots of built-in effects).  I don't know if it has any PCM
partials as part of the sound.  The other new instrument is an expansion board
that can be put into some of their current models (such as the MU100R and the
SW1000G).  It is a full-featured FM sound module that has a new expanded type
of FM, but is fully compatible with old DX/TX/SY sysex data.  Of course, the
FM sounds from this card can also be routed through the (quite substantial)
internal effects in these units.  I think this card will be about $300.00 US.
