Quoth George Kaye: “Does the Casio have XG, not just GM sounds?The Yamaha 540 does. … Does the Casio offer a multi effect DSP effects processor besides Reverb and Chorus for using effects like Rotary Speaker, Guitar Distortion, Wah effects, etc.? The Yamaha 540 does.”
Quoth Clif Anderson: “Isn’t it a little unfair to criticize a Casio for not conforming to Yamaha’s proprietary XG format? I thought the Roland VA-7 was supposed to be the best sounding arranger keyboard at the high end, and it does not conform to XG. I think the same is true of the Solton X1 and will be true of the upcoming Korg PA-80. The Roland VA-7 does conform to GM Level 2, to which none of the low end arrangers conform.”
While it’s true that XG is owned by Yamaha, they
are willing to license it to competitors. Korg makes XG-capable synths (complete with the XG logo), and ESS makes XG-compatible (complete with logo) sound chips (Maestro, etc.) that compete directly with Yamaha’s own YMF series for PC sound cards.
Indeed, XG exists in the
first place because Roland renéged on their promise to make GS available to competitors. Yamaha first made a fully GS-compliant tone generator called the TG-300B, and submitted it to Roland to license the GS logo and rights to use the GS term in advertising it. Despite their prior assurances that any maker of any MIDI device that met the GS criteria could license the GS name and logo, apparently Roland decided to have one of the “GS criteria” be that the device had to be made by Roland. So, neither Yamaha nor anyone else could use the GS name or logo.
So, Yamaha got sick up and fed with Roland’s backpedalling and obvious attempt to falsely promote a proprietary format as an industry standard, and decided to one-up GS, and so was born XG (which is superior in most respects, having had the advantage of 20/20 hindsight on GS’s mistakes and limitations), which as I said before, Yamaha
does make available to competitors.
To this day, all XG devices from Yamaha (yes, including the PSR-540!) have a “TG-300B emulation mode” built-in — while they can’t say so in their specs, this mode actually
is GS!! It even recognizes the GS System On MIDI SysEx message that all GS MIDI sequences have near their beginnings, and automagically switches to that mode! It supports all the sounds and enhanced SysEx features of the original Sound Canvas.
So, the PSR-540 can play GM1, Level 1 XG,
and Level 1 GS (but not GM2 — yet!) MIDI sequences as-is, without modification, exactly as the arrangers or composers intended. But so can my $15 YMF-724-based PC sound card.
