The Wavestation doesn't use bespoke Yamaha chips the main CPU is an off the shelf Hitachi CPU, and the Tone Generator Chip is the Korg TG88 aka MB87726 which was made by Fujitsu only used in Korg products, and was part of the TG88, DF88, WS89 chipsetThis comes from the people that designed the Wavestation, and is easy enough to look up... It was the Yamaha voice chips they were using that couldn't do proper filters, hence the "workarounds" in the WS
The DF88 Chip was used for the filter, mixer, and Amp Envelopes and the WS89 was used for the effects
If you crack open the case you will see all three of them labeled with Korg logos and the Korg part numbers

Maybe they meant the chips Yamaha let them use?
Korg replaced the TG88 and DF89 with the TG92 and DF93. The DF93 used in the Trinity had resonant filters
