Hi John
the Virtual Racks/MIDI Virtual Racks presets have all dry sound in them. If you read the INFO menupage of Lead Tone Poem preset, it says to set dry/wet on 100% wet. Very likely you have your H7600 signal managed in parallel to your preamp dry signal…so 2 instances of the same signal, analog dry + digital dry (7600), are causing the phasing issue. To use these presets you need to remove the analog dry signal and let the H7600 provide both of them, keeping its FX balance on 100% wet.
all the best
