Hello -
I have no problem with SendSX under XP. Make sure you're using the latest beta available on the forum, and that you're not throttling the MIDI messages too fast for your interface (DOSBox will likely have no problem since it's capped at 1 KB/s).
Are you talking about the delay setting? I experimented with values between 0 and 250 ms before deciding there must be something better and moving on. What value works for you?
I'm just as happy using DUMP and DOSBox, though. Given my very limited need (I just want to send the .SYX files for soundtracks that don't already have the data embedded), that works fine.
Thanks for taking the time to make the suggestion though.
There's a great little program called vanBasco's Karaoke Player that let's you dump sysex to the MT-32 as well as play MIDIs.
How do you like it as a MIDI player? Win Media Player works fine, but it is a PITA when I'm in the middle of a soundtrack and then need to listen to a WAV file for work reasons -- when I'm done I have to reload the soundtrack and try to click back to where I left off. Having a dedicated MIDI player would probably be very convenient.
