I usually have my input level at about 12 and that can still clip if you really bang it but one seldom do.
Ah, Granados makes me wish for May. We have still snow where I live but according to the weather news, it should rain the next coming days and perhaps after that, we can get spring. But where I live, there usually comes snow a couple of times in April and actually, when my daughter was born at the 9:th of May in 1999, it was snowing! But that is rare.
You play all the Chopin beautifully Monica. I know the preludes well even though there is a couple of years since I played them and these are really well executed. A bit different interpretated "than mainstream recordings" in some passages which it comes to dynamics and accents but I really like it as it seems like you have a clear musical understanding what you want to achieve.
Chris said, "not a wrong key" but I am pretty sure there I hear a tiny slip in the 21:th prelude at 1:21 but you hide it really well with the pedal

.
The end of some of the "sketch alike" preludes are alwats a bit difficult, like Chopin not really had a clear program for it and they tend to fade away. But I do prefer these before overlong endings as he sometimes do in his larger works (nothing comparing to Liszt though who can go on in minutes before finding the correct chord

). On the other hand, it might be the case that it should not feel really finished but rather start of next prelude. I believe they are clearly connected and fits best executed as a chain where all the tension built up is neutralised with the last prelude's deep D, D, D.
The Mazurka is also really well played and quite exact as I want it to sound.
Overall, bravo Monica!
