I'm looking to make (or modify an existing) a simple 3 band EQ - High Pass, Band Pass with adjustable freq and Q and Low Pass. I've trawled around looking at old posts.

Is there a problem with simply dividing an audio source into three and using [hip~], [vcf~], [lop~]? Will that cause complicated phase issues (that I only dimly understand)?

Does such a patch already exist? I'm a strictly vanilla user.

Thanking you all in advance for any tips.
