"Proprietary spectrum control" is just a filter applied in the signal path after the PCM oscillator - so exactly in the same way everybody else (e.g. Roland etc.) were doing this. Nothing unique here, even back in 1990. And "proprietary" means they had to write their own code (instead of using any open source code).
The 99 was the ”flagship” back then. It had better effects, more keys (76 vs 61), and a larger PCM ROM. You could also import small user samples. I remember people making some really nice user patches for it, like one famous Rhodes set. The basic technology was the same: the idea to combine samples with FM.
I've got my finger on a few SY77-85-99 in eBay but /hopefully/ this (SWAY) could turn the table @_@ BUT... I could cheaply use DEXED plus any WT VST -_-
well not so easy SY77-99 could use samples as an FM modulator as remember right in software we got only Tracktion F.'em that is more closer to SY's

Close but that would be a quite a bold statement. 8bit DWG's of DW8000 are pre-calculated mathematically generated waves that are used as are DCO more closer to PPG wavetables than PCM\AWM like Romplers type
Yes that would be quite a work for the developer: firstly PCM could be copyrighted, than he will have to decode the PCM part of the EPROMs because Yamaha are known to encrypt PCM part of their wavetable ROMs. As I see he is also struggling to do the EG's right, SY series had whole bunch of them, different and depending on the type of synthesis you use. Doing envelopes right is more important than being 100% closer in sound. I wish him a good luck Wavecards for these synth series are easy accessible on the net https://www.sector101.co.uk/waveblade.html interesting will this project be capable reading them Last edited: Jul 21, 2025 at 2:09 PM
Yes, Sway reads all those Yamaha waveroms, the SY77 core waves, and the Yamaha expansion cards just fine, and has done for ages. Obviously Sway can't officially bundle them for copyright reasons, but if you have them, you can use them in Sway.
Some time ago there was an attempt to mimic the complexity of SYseries synthesis in Reaktor SY-66: https://www.kvraudio.com/news/weirding-module-releases-sy66---free-fm-synthesizer-for-reaktor-19428 https://www.native-instruments.com/en/reaktor-community/reaktor-user-library/entry/show/9885/ if someone is interested in a long gone ensemble PM me. While trying remembering the name of this ensemble I found funny project made in SynthEdit: https://www.fiedler-audio.de/mf77-fm-synthesizer-mit-rcm-wavetable/ Last edited: Jul 21, 2025 at 2:32 PM
Unfortunately, he hasn't found anyone to continue the project. I advertised it years ago in the hope of finding someone to finish programming it. Here's the original text from his website! Publication At this point, I would like to expressly encourage anyone interested to contribute to the further development of the program. The sources can be found below as a ZIP file. The program is expressly released as an unfinished version under the Creative Commons CC-by-nc 3.0 license. This, of course, only applies to my part in the project. Brands and technologies such as the VST interface from Steinberg are not affected. The condition for republishing is: The synthesizer must be offered free of charge. Please mention my name as the original author and, of course, add your name as a co-author.
