Yes it is unfortunate that F/F feeeding SOUT is also reset to zero along with all registers on NRST. A bit of an oversight for a serial link IMHO. I forgot I altered my version of ELBUG (Elektor OS) to output a high condition immediately on reset so I didn't get this problem.

Rather than having to invert everything, perhaps a simple circuit using one of the Flag outputs to gate SOUT. Then have a simple prelude in MIDI routine to first set SOUT high and then release Flag gating SOUT output (using a 74126 ?).
