Tempo has nothing to do with pitch. When you alter a tempo the pitches of the notes should not change. if your DAW is changing a pitch when you adjust tempo something is wrong.

When turn tables (records) were used, changing the speed of playing also changed the tempo but that's just a technical matter. A piece of music that you play with any instrument can be played at any tempo without any regard to pitch.
Softwares today are able to play music at different speeds but maintain the original pitch. Windows Media Player has that option, DAWs of course have that option etc.

In the old analogue days, with turntables and taperecorders the pitch did change when changing speed. It's quite logical, if you know that a pitch depends on the number of cycles (repeated waveforms) per second (e.g. A=440 Hz). If you speed it up, the number of cycles each second goes up, so the pitch goes up too.
Nowadays software can indeed change speed without changing pitch. It compensates the speed change via some kind of algorhythm (so there are quality differences at that level!).

maybe your tempo should be adjusted to your root note by a power of 2.

Does the root note of a track change when you adjust the tempo?
