Pitch

b. 424

composition: Op. 11, Concerto in E minor, Mvt I

..

In the sources, there are no sharps before the d2 and d​​​​​​​3 semiquavers. It results from a different rule of validity of accidentals from the one applied generally in contemporary editions where a part of a bar is written with the use of an octave sign. In Chopin's times, a mark next to a note encompassed with an octave sign was often considered valid also for a note written at the same pitch, yet not encompassed with an octave sign.

In FE (→EE), there is no accidental before the 2nd semiquaver. A sharp necessary to achieve c​​​​​​​1, undoubtedly intended by Chopin in this case, was added in GE.

b. 425

composition: Op. 11, Concerto in E minor, Mvt I

..

In FE (→EE), the  before the last semiquaver was overlooked, which was corrected in GE. Moreover, instead of a  before the 8th semiquaver (c​​​​​​​2) the majority of the sources (except for GE3) feature a respective mark on the 5th semiquaver. It is related to the use of an octave sign to write the 1st beat of the bar.
