Updating Cakewalk by Bandlab does not affect a pre-existing install of TTS-1. Once TTS-1 is installed, TTS-1 remains installed until it is removed. I have the latest version of Cakewalk by Bandlab on this Windows 10 laptop and a Windows 11 desktop. TTS-1 works fine on both machines.

The TTS-1 soft synth works with any program that can use a DXi instrument. DXi and VSTi plugins were introduced at about the same time by Microsoft and Steinberg. The audio production community embraced the VST format while the DX format is used primarily in games. While Cakewalk by Bandlab and Band-in-a-Box can use DX plugins most other audio production programs can not.

The TTS-1 was built by Roland for Twelve Tone Systems to use with Sonar products. The TTS-1 is essentially the same product as a software product Roland distributed under another name called HyperCanvas. The differences are the color of the GUI, HyperCanvas was available as both a DX and VST plug-in and the TTS-1 installer is Twelve Tone Systems/Sonar/Cakewalk product dependent.

Roland quit support for the TTS-1 at the same time Roland quit support for HyperCanvas. Sonar offered to support the TTS-1 but Roland said no so the TTS-1 has not been supported for a few years. Last year Roland demanded Cakewalk quit providing the TTS-1 installer.

So if you have the TTS-1 it will continue to work. But you must install an older Twelve Tone Systems/Sonar/Cakewalk product that includes the installer for a new installation.
