Focusrite is a good brand. Nice quality and you should easily be able to monitor in stereo. Since the interface has 2 channels, it can and does monitor in stereo. Be sure to use the ASIO driver with the 2i2.
Believe me, it does not. Not by default at least...
To get stereo monitoring, you must have a stereo source. For audio on the 2i2, that means having a left and a right output from the keyboard and putting one into the 2i2's right channel and the other into the left channel. Waaa laa.... 2 channels and the result is stereo.
R&L of my dig.piano are plugged into R&L of 2i2, it records amazingly in stereo, but the direct monitoring is still MONO.
Thats normal behavior on this gear, according to THIS review
https://simplehomerecording.com/2014/09/25/focusrite-scarlett-2i2-review/ (read the "output" part) I quote "...small complaint is that the direct monitoring is always in mono."
So, anyone know a way to get stereo monitoring? may be some soft or driver?
MAY BE SOMEONE OWNS A 2i2 AND CAN GIVE SOME HINT?
