This can create a compositional problem since often quite disparate means of expression will need to be used between the instruments while trying to maintain compositional unity. Some combinations work better than others. For instance recorders combine well with harpsichords, which share dynamic limitations, but not so well with pianos. This is partly the actual sound which doesn't seem to blend well but also pianistic musical language. Strings can work effectively, as can other woodwinds so long as the difference in styles as well as in timbres are considered and exploited.
Brass tend to be overpowering but can be used effectively in alternation.
Interestingly music for brass often works well on recorders and vice versa. Pianos often do not work particularly well. Electronic modification of recorders does work quite well.
