Silly me,

yes using Word8 instead of Ints got rid of most of the fromIntegrals. I didn't know that Word8 was an actual haskell
type. Thought it was something private to ALSA.Sequencer.

There is one remaining fromIntegral. This is "time"


    Couldn't match expected type `alsa-seq-0.6.0.2:Sound.ALSA.Sequencer.Marshal.Time.Tick'
                with actual type `T'

This seems to be realy a private thing and I found to way other than fromIntegral to make the compiler happy.
