Also on my standard setting with the orphinit driver I always had P at 330 and this didnt cause any issues. But maybe orphinit just ignores this setting?
It is important to point out a significant difference between UNISOUND and ORPHINIT. UNISOUND uses the BLASTER environment variable to determine how the card is configured; ORPHINIT does not. ORPHINIT reads the settings from the .INI file (ORPHEUS.INI by default, if you don't specify a different one), configures accordingly, then, if you used ORPHINIT.BAT to start it, will over-write the BLASTER environment variable, so that it corresponds to the actual hardware settings.
With ORPHINIT, the on-chip (CS42237) MIDI port is disabled by default (as keropi explained), and PCMIDI is on 330H by default. PCMIDI is controlled only via the 0n-card jumpers, so unless you changed them, it is at 330H, and neither UNISOUND nor ORPHINIT can change that.
Lastly, unless an updated version of UNISOUND was released that addresses this, Orpheus II and Orpheus II LT support are not implemented. This means that you will either get no FM sound at all, or will be limited to Crystal FM. If you don't use the FM synthesiser at all, then this doesn't matter.
