hi guys! so, x64 version is finally out! this is ALPHA, I haven't tested it thoroughly, but it seems to work Changelog: Added support for 64-bit Windows (Vista x64 and Windows XP x64) Added digital signature for the driver and the installer (signed by CEntrance, Inc.) DSP plugins and Add-ons from previous versions are no longer compatible! Added experimental support for 44.1kHz mode for E-DSP devices (kxctrl-tweakable, use on your own risk) Fixed E-DSP KX_IN/KX_OUT assignments for ASIO kX is no longer installed into windows/system32 folder, but stays in 'Program Files'. do NOT copy any kx files to system32! Added to the driver installer KXM and micro effects by stylus [see the SDK for instructions] Fixed multichannel fxbus assignment issue Fixed issues with loudness compensator (based on Russ changes) SFMan32.dll is not installed for x64 platforms, because it is not 100%-compatible with 64-bit OS Removed card/model information from the INF file (and in Device Manager you will only see 'Generic' cards now) Known issues: Launching KXS, KXP, KXL files from Explorer might not work in Vista due to UAC Speaker Test does not work in Vista SPDIF AC3 output may not work correctly in Win64 CodeMax library is not supported under Win64 SDK / For developer: iKX class updated to be cross-platform [supports OS X now] (note the changes in create(), open(), close(), destroy() - see kxctrl sample) edspctrl is cross-platform now kxctrl is cross-platform now Most of the SDK sources released under GPL (GNU Public License) SDK license agreement updated Since the mixer is no longer in system32 folder, kFile::get_full_skin_path function is used (see efx-tube example) Most DWORD pointers in SDK replaced by uintptr_t: e.g. publish_plugins, iKXPluginGUI::extended_gui, kMenu::track etc... Certain 'ints' replaced with 'size_t' MFC Timer uses UINT_PTR instead of UINT, if your code uses timer, update accordingly (see 'dynamica' example) kxparam_t is 'int' for x64 builds, thus, most DSP effects need to be updated iKXPlugin::get_plugin_presets() returns kxparam_t* instead of char * (all plugins need to be updated!) Most char pointers updated to 'const char *' This version will NOT WORK/INSTALL on x86 OSes! Don't even try ---- Windows Vista x64 and XP x64 require a digital signature from the software publisher (unless you run Vista in "Test" mode). This signature is too expensive for freeware products such as kX. For the last several years I've been working for CEntrance, Inc, most recently developing aggregated audio drivers for 'MicPort Pro' and 'AxePort Pro' -- portable 24/96 USB interfaces. Thanks to CEntrance, kX Drivers for all the platforms are now signed with their certificate. So, don't be surprised if asked whether you trust CEntrance, Inc. when installing the kX driver ---- Plugin developers are encouraged to review the new SDK and update their plugins accordingly. If you have any comments, suggestions, please feel free to drop me an e-mail. The next x86 release will incorporate all the changes found in x64 version, thus, all the plugins will need to be updated. ---- x64 users: please test the driver, report any problems, bugs, issues whatever. This is a majour code update, that's why bugs are expected x86 users: I will release x86 version soon. I encourage you to test it. ---- download link: http://download.kxproject.lugosoft.com/downloads/kxdrv3546-full-x64.exe bug reports: http://www.driverheaven.net/bug-reports/182462-x64-3546-bugs-issues.html best regards, E.
