b) Who else uses chips from Dream ICs in their products ? Are the likes of Casio, Yamaha and other big names doing so without disclosing it ?
Yamaha is very unlikely, because Dream's chips do not support XG. Casio is also unlikely because they like to reuse their own sound banks (in fact one of the complaints with Casio is that many of their cheaper products share the same ages-old GM bank...). Kawai also use their own banks. All three of those also have the capability to produce their own chips (Roland too). OTOH, many smaller manufacturers very likely license their banks from one of the large manufacturers or Dream...
But well, there are enough videos of hobbyists popping open all kinds of synths on Youtube where they point out the various components to do a little research to try to find some synths using Dream chips (if you have the time) 😉
Although I also expect that you would find some of those chips in unexpected places (karaoke machines, mobile devices, arcade machines (as far as they still exist), video game systems, etc.), based on what I know about to what kind of manufacturers license their technology to...
- some of Yamaha's chips (that are not used in many synths) are actually specifically designed for use in karaoke systems and other systems that need voice synthesizing.
- Zoom's RT-323 drum machine has the same chip at its heart as many arcade machines
- Texas Instruments made sound chips for Apple
