I will ty to give feedback for all of your comments on one post

. Sorry about the dot!
First the Edirol. This was the very first recording with it and I will probably manage it better soon. The hiss and the continuous noice is probably because of it. It clipped several times during the Rach prelude for instance and I put it underneath for the first recording. Will try another position next time. Perhaps some distance away from it as from a listeners perspective.
Overall, I have played all of them, but for the Rach prelude, a long time or rather, learned them a long time ago. I actually had a recital including the Sommarsång when I was 11 (perhaps 12). And Chris know that I have not played much as he know what I have been doing

. Unfortunately, I have not really played much the last 1 1/2 year or so. Will try to change that when the autumn arrives in Sweden and the garden and outide house work close down.
Bach
I made them deliberately slow. Like to play them like that as I want the melodies to come out better and the mood of the pieces fits better. I got a plan with them and will probably record the entire set one day. They did not come out quite as I wanted them to and I perhaps got a bit too careful when I made the recording. I tend to get a bit stressed when I know I am recording something and become a bit too safe if you understand what I mean. Trying to not play a single key wrong (which I do not think I did).
For no.1, I made a tempo mistake in the end. Stupid mistake and the magic did not really get there.
No.4, I do like to trill them all the way through and it is actually a bit tricky as you need to find the steady 32:th beat and keep it all the way through. I used to have a much faster version of this one and perhaps do that some day. But this will probably be the last recording I replace of these three.
No.8. Not very happy about it. As Chris said, lot of bad syncings between the hands and this is actually an invention that could be played faster.
Ravel
I am not sure what you mean by taking liberties with the score Chris. I play the keys exactly as in my score. If this is wrong, my score is wrong but I doubt it as I got it from a teacher who enjoys Ravel a lot and have studied in Paris. I got the version which is adjusted for left/right hand. About rhythm, it is marked
d`un rythme libre for a reason isn't it?
Peterson-Berger
This is actually not so good and I believe I knew this better than I did when I recorded it. Tried to look at the sore and play it along but as I cannot sight read very well, this was rather confusing so I played it from memory with a couple of bad fingerings here and there. It is from bad fingering you hear the mistakes. Not happy with it and it will be re-recorded for sure after some study of the score.
About recording the whole set, not impossible but I have never played a single piece of the others. Not too difficult though.
Rachmaninov
A-part is rather well, the B-part good enough even though I miss here and there but that is not really audible as you accent the first key in each triplet (one mistake is obvious though). But the repeating A-part is not good. Wrong notes, hesitations and loss of tempo in the large chord section (don't you just love these eight key chords!). Play it from memory and have not really studied (not even read it actually) the score here.
But as you point out, there should be more distinct changes in dynamics but also, this is kind of my way of playing. Will re-record this for sure as I have not really learnt it properly yet. Pianolady, you are right about the top key of right hand is not accented well enough. I have heard that before when I played it.
