I have a Roland RD-300SX digital piano and it is connected with the Roland quad-capture interface. I connected it with a 1/4" jack. I want to use the sound of the piano itself.
The problem is that the quality of the output coming from the interface (either monitors or headphones) is lower than the quality I get when I connect the headphones directly on the piano. It is lower not in terms of noise and scratches etc., but it's just a poorer piano sound; not so deep, not so natural.
It is really upsetting me cause the audio piano sound of Roland is so good. How can I improve the sound coming from the interface?
