Another idea is not to use a loop, but just send events 1 by one at the SR in an UDO. You set the ksmps in it to 1 and then use control flow to write to the table, e.g.

if kwrite == 1 then
 k1 table  kndx, ifn
 OSCsend ...
 k1 = k1 + 1
 if k1 == flen(ifn) then
    kwrite = 0
 endif
else
 k1=0
endif
