Hi, I need to update my freshly bought (used) SP-555 from v1.3 to 1.4. The instruction say that I need MIDI interface to perform the update. Isn't the 555 a MIDI interface by itself? Do I need external one? If so, will the RME Fireface 800 (with firewire connection) do? Shall I use Fireface's own ASIO drivers? Or maybe using the PC's built in MIDI interface is ok too (although I don't know if my has one)?

Thanks!

No: SP-555 + usb cable + computer + SMF sequencer.

There's a readme file with detailed instructions. Roland provides the SMF sequencer (win or osx version).

Follow the instructions and everything should work fine.

Thanks, sharpmotif for a prompt reply! I thought so but here

they say "You will need a MIDI interface on your computer to use this program". So they confused me a little here and just liked to be 100% sure if I can use 555 as interface as well.

Yeah, that's a little confusing - I remember thinking the same thing before checking the readme.

IIRC, after getting into the update prompt on your SP-555, all you have to do is open the SMF sequencer, select the SP-555's MIDI IN, open the MIDI file (update) and start the sequencer.

I think it takes like 5 or 10 minutes after that for the update to be complete.

While I haven't noticed any improvement over 1.03 (my CF cards always worked fine), I guess it's worth it just for the sake of having the latest OS version.

This link has instructions: http://www.roland.com/support/article/? ... =1812362#6 (I think it's either the same or better than the readme that comes with the zip file)

All went well and my new Transcend 2GB 133X plays well too. Thanks again for all the info!
