Hi, is the DLL at: http://www.midibox.org/dokuwiki/doku.php?id=hardsid.dll&s[]=net the latest version? Since on some thread also this is linked: http://midibox.org/forums/applications/core/interface/file/attachment.php?id=9560 Which is the latter? Anyway, I'm running Win7 64, and it does not work with Acid64 player (it starts to play, the volume bars are live, but my sammichSID does not react), Sidplayw (nov 7 2002 version), or the new Sidplay26w. I can play SID files back only with the asid_xp software. But it plays some files wrong (like Barbarian crawls at a really slow pace, and the speed function does not change things), and also shuts down improperly leaving the tune playing, and when I kill the process, sammichSID hangs and needs a restart. So is there a Win64 SID player for the midibox right now? My MIDI interface is the one in TC Electronic Impact Twin. The device is quite high spec, but maybe the interface is just too slow? (then again, I suspect there's not that much happening with the Barbarian tune what with not much ostinato stuff of strange tweaks)
