The spider valve mk 11 and Spider IV amps offered Intelligent Harmony. I do not see this feature in the Spider V amps? Does any one know if a patch is offered for this? The harmony synth on the Spider V amp have no value unless you are doing 5ths or Octaves. The Intelligent Harmony feature on the Spider valve Mkii and Spider IV amps had Intelligence in the Key of selection and the selection of Major, Minor etc. It's a really great feature which also incorporated 5ths and Octaves. Can't imagine why this would have been discontinued. Looking for anyone who has any knowledge or help on this. Thank you
