In order to avoid potential phase problems, using a single (mono) amp and having an h9 and a time factor (after the h9, used mainly for modulations) do you think is best to connect the h9 and the tf in stereo or mono? would this never affect the phase anyway? thanks in advance.
I think It just depends on what sound you need, because the setup might change the sound a lot. Say if H9 is on a pitch algorithm and stereo routing is used, two pitches will be delayed/modulated separately. Same applies to delay algorithms on H9. Two delays will be delayed/modulated independently, which sound very different if you use mono connection.
