Pedro, As Darrell suggests, it seems definitely the "feed back button". If you are reaching for infinite loop, and it seems that you are, then turn the feed back button all the way up. MIDI Dump Undo Parameter feature or what ever you are describing has nothing to do with the feed back loop dissipating, if that's what you are trying to correlate the problem to. As for "C'mon guys this is the reason I subscribe...", no one's paying us. Your subscription to this "wonderful and informative" forum is a priviledge, in my opinion. Have fun looping.

C'mon guys this is the reason I subscribe to this particular newsletter: I own and operate am EDP with maxed out memory which had v3.2 loaded. I ordered the v5.0 upgrade from Kim and received same today. I installed the new EPROM's per the instructions and reset the EDP. Now for the problem?: When I hit record the Undo led does not light up in yellow as i've grown accustomed to AND when I finish my loop and hit record again (to let the loop play on and on), the loop begins to fade with each successive pass and the Undo led glows green. The only way to restore the volume of the loop is to hit Undo after each loop. I read through the new instructions and fact sheet and don't know what I am doing wrong. I've checked every parameter setting and have set and reset each one as before and still no luck. I have another EDP at home so I checked the settings there which are identical save for the ddd under the Midi-Dump Undo parameter feature which is not coming up at all on my new upgraded EDP. Kim, gang, anyone please share some wisdom and insight..... PedrOOrdeP PostScript: I am not using any midi function that I know of and am only triggering the EDP with the footswitch.
