Preserving sample length

[teikill]

Hi, I've discovered that loops changes speed when changing key. I have a two bars bass loop in 150 bpm The length is said to be 76800, I don't know what that is. The root is e2. If I play f#2, the sample will move faster, and then it will be useless. So my question is how to preserve the length.

Yes. That is how (re)sampling works. In Pro mode TX does however support timestrech, pitchshift and timeshift engines, of which probably the latter will do more or less what you are looking for (sync a given bpm while still doing non-playback speed altering pitch transposition). Be aware that the two latter modes don't play super well with heavy transients (i.e. beats) though.
You can turn on Pro mode in settings and try it for free to decide if it fulfils your criteria.
Btw, 76800 is number of samples.

Thanks. I have the Pro version, but I can't seem to find the timestretch and timeshift options.

Found it under groups! Thank you!
