The video is heavily hinting a Yamaha CS reboot of some sort or another.
I guess a virtual analogue with hands on control and nice keyboard action,
an analogue signal path is too much to hope for i would guess

For review, all the digital logic in the beasts use standard (and mostly still available) CMOS chips. These are old DIP packages that only fit a hand full of gates in each chip. They are all run off of +8.5v and -6.5v. This weird arrangement fits in the 15-volt supply that the chips can handle and being offset allows analog switch chips (e.g. 4051, 4016) to process the analog control voltages and audio signals that are bi-polar around zero volts.

> Again, the catch is that this board has 3.3volt digital I/O - which is actually pretty high compared to the latest chips! So, I need to translate a lot of signals. The old standbys were the 1488 and 1489 chips that were design to translate from 5volt TTL to +/- 12v (or lower) for RS-232 serial ports. I might be able to use these but they would take up a ton of room and I'm not sure if they'll work with 3.3volt instead of 5volt. I looked around a bit yesterday but found tons and tons of possible chips and was hoping someone here might know a good chip to use. I'd like something that's 3.3volt on one side and up to the +8.5v/-6.5v Yamaha levels on the other side. DIP or SOIC package would be fine and I'd like 8 or more channels in each chip with versions for one-way and bi-directional.
