No, the recorder is easy - like any flute, the sound radiates from the edge the airstream hits.

You have a slight problem with instruments like ocarinas and Asian or Eastern European whistles where the voicing is on the back. And dizis must be a pig.

I guess oboes are like clarinets?

Stupidest sound guy I've ever encountered was one who tried to amplify a harp by pointing a directional mike at the strings. Most harpists now fit their soundboard with internal contact pickups.

Pictures of Selim Sesler I can find on the web show him using a barrel mike, not the directional one I saw him using in a live concert. I don't understand how barrel mikes can work - I once used a mike fitted into a tube welded onto the headjoint of a flute picking up the inside of the bore, and it shrieked like a banshee when you hit high D because the mike was right over that note's antinode. Sesler was not exactly reticent about high notes.
