I´m trying to record (and play live through speakers) AUDIO from the Roland TD-1DMK trough the UR242. The connection is as follows: TD-1DMK audio output > stereo jack > UR242 Audio input > UR242 Audio output (L and R) > Y cable > speakers (Bose desktop speakers with single mini jack input).
TD1-DMK has drum 15 kits. When selecting any drum kit other than drum kit #1 (the dry/basic kit with no noticeable FX), the sound coming out of the UR242 is HORRIBLE and at a lower volume. To explain, when selecting drum kit #2 , apart from this strong toilet-like reverb being added even to the metronome, the snare and kick sound like what you can find in a toilet, the toms bad, and the cymbals not too bad.
The UR242 Inputs are (symmetrical) mono Inputs! Pluging a Stereo Output Jack into that Input will mono the Signal and additionally polarity reverse one side of the Stereo Signal.
