The BK5 was recorded as an MP3 directly to the inexpensive Tascam Dr-07...
I am sure a better recording quality can be acheived by recording as a wav via BK5 audio recorder, and converted to MP3 via MixCraft..
Tonewheel, I agree with most of your comments, but I don't think Roland brushes are bad or even the worst of the lot..
I would like to hear Diki record the same styles I recorded on the BK5 with his BK7m..to get a better feel...if there is any difference...I don't think there is...sample wise...I would think settings are more of a factor, and surely recording gear...and method..
