This is legendary thank you so much bro! If you were using a high pass filter in a build or intro on the kick or kick and bass is there a solution or workaround to stop it changing the length of the kick?
Linear phase is an option, or making sure the hp is engaged so high that the it shortens the sound. Honestly you will get some phase shift from moving around high pass filters whatever you do (unless you use linear phase, which has it's own issues like pre-ringing). I just use a normal filter and don't really bother trying to rectify it...
