Speed up steps and sound pitch problem

Thanks for codecguide codecs and media player classic player.
But after every update i am looking for this easy correction but nothing has changed over time.
every step for speed up or down that current player has in default is set to %50. This is too much
it should be a more reasonable ratio; such as %10 or %12,5
and in default mode when you speed up sound pitches. this is so annoying. and after reinstall or install in a new machine i should have to make settings to not to pitch the sound.
it should be set to not to pitch default.
thanks for all

You can change the speed step size:
options > playback > speed step

For pitch correction you should select the internal audio renderer:
options > playback > output
