Hope you can suggest some help here , maybe I am doing it wrong , not sure , we don?t usually setup the tuners , but in this case the client requested to have fm radio working When configuring presets on the fm tuners in the MARPA software the following does not happen . You cannot get the tuners to change between presets from a touch screen or from a DLT switch . Here is how it is currently setup verison 3x ( black case ) matrix Under the tuners tab in marpa 4 presets have been setup . Under the sources tab at the tuner 1 page the following has been setup . Dynamic 1 = Media control . Dynamic function = NextSelection(tuner preset) Media link group = created a group called it ? tuner1presets next Done the same for tuner 2 Now in the piced software open the ctouch mark 2 project file and configured a button as follows . under the system io tab key function = preset system io variable = inbuilt media transport control fast forward value = 1 media link group = tuner 1 presets next no luck here , does not set tuner to next preset . is there perhaps another way of doing this ? also tried setting it up on a DLT switch but you cannot set 2 different applications (lighting and mtp ) on the same switch , I need to investigate this method a bit further , perhaps you have done this before and know of a workaround .:confused: please advise
