bass wobble when using pitch shift effect

When I play I use backing tracks for small clubs and restaurants. Some songs are in Eb and some are in E. I play in E so I want to change the pitch a half step up. When I do this I sometimes get a wobble effect in bass after the shift. I saw an apple app that shifted better but I can’t find it for windows.
Is there a way to avoid this wobble or is there a better pitch shift app?


Try the Sliding Time Scale / Pitch Shift…
