Re: DX21 and TX7

Hi Guys, I'm working on an acoustic piano patch right now, but on an FS1R.? You can't do the piano justice on something as simple as a DX7, there just aren't enough Operators.? Your estimate of about 30 sine wave operators is pretty close to where I'm at, using the complex wave forms in the FS1R will reduce that by a factor of four.? I'm trying to beat the quality of the original piano patch on the FS1R done by Manny Fernandez, and I'm trying to do it with just one Part (just 8 voiced Operators and a few unvoiced).? Manny used two Parts in the factory patch, which has difficulty in the mid-range around middle C.? His latest FM-X piano patch is much better, but it uses 8 Parts on a Montage.? That's massive, 32 FM-X Operators!? Manny has done a few FM tutorial videos on it for Yamaha on the Yamaha Synth site.?

I'm attempting to use the Inharmonicity concept from the VP1 and all of the complex wave forms in the FS1R (and a spectrum analyzer) to get an piano FM patch compacted down to just one Part.? I want all 32 notes available, not just 16 on my FS1R.? (I don't have the 128 FM notes a Montage provides.)? If you hold down the sustain pedal, it eats up polyphony really quickly.? Pieces like Ravel's Jeux d’eau have gaps where the sustained notes cut off due to polyphony at 16 notes.? I'm about 2/3 of the way there.? Another weekend or two and I'll have it.? It's already sounding much better than the factory FS1R pianos, I just need to thicken the sound in the bottom register and fine tune the top two octaves by de-tuning the note strike a bit more.? I've got recordings of a Yamaha CP70 grand piano I'm working to.? The patch won't be that high in quality, but I'm hoping it will be better than any other current FM piano patch.

Since I'm cheating and using a spectrum analyzer and an FS1R, it's only going to take a month.

Hi Daniel!

Best Regards,? Thor?

Agreed, but it was always a matter or perspective.? The stages I played on couldn't support a CP-70 (nor could my budget), but I dragged a CP-30 around with me.? (I especially liked how the top cover turned into a stand.)? But if I was playing in say, a synth-pop group that did *one* '50s medley, the DX piano would have been tempting -- particularly if I didn't solo.

I remember reading that Dr. Chowning thought that FM could ultimately clone complex instruments like piano and violin.? The problem was the amount of effort to get the attacks and other 'stuff' (Yamaha's term) right.? It would have probably taken 20-30 operators, and a half a year of a good FM programmer's time, to get all the nuances right!
