Good call, this is absolutely correct. Sine waves don't respond well to filtering because they are, by definition, just a fundamental frequency and nothing else. Definitely use something else like a saw or pulse wave (or something even more harmonically complex, like a found sound) for this task.Isidoor wrote: If you want to synthesize a sub yourself it's often better to not use sinewaves but LP filtered waves with some higher harmonics present.
I should have mentioned this in my first post.
