I can not install my bcd2000 to windows 7. the hardware and softwere

You need to get latest USB driver for Windows 7 (both 32bits and 64 bits available) at:

I think the SMF converter though is a 32 bits application will work on windows 7 provided the correct USB driver has been installed.

The only Voyetra Midi Orchestra Plus software I can know was written for Windows 3.1 and Windows 95. Thus there are several reasons for it to be incompatible with Windows 8. First, it was a 16-bit software; the most common Windows 8 installs use a 64-bit OS. This means that the OS has undergone a number of major changes. The installers are completely different (format/way of talking to the OS). The DLLs that communicate between the software and the OS have also changed. The drivers for MIDI devices will be totally different in the modern OS.

The documentation for Voyetra Midi Orchestra is available here: http://www.turtlebeach.com/support/files/241/ . It is a discontinued product and no one at the company that owns it will be writing a new version of the code for Windows 8. I'm not sure this software will work in Windows 7 32-bit. You might be able to use the software in a compatibility mode from a virtual version of XP. For Windows 7 Pro, Virtual PC and the XP mode package are available as free downloads and can be used if your hardware allows. Windows 8 Pro has Hyper-V but requires a licensed version of any Windows OS that you want to use. For non-pro versions of Windows software, you would need to buy a Pro upgrade. The alternative is to obtain another Virtual machine software (VMWare, for example) and a licensed copy of XP or an older version of Windows. (OEM Windows 7 Pro licenses are still available from many computer hardware vendors.)

I hope this helps.

(Many 32-bit device drivers don't work under Windows 8; older software that didn't run under Windows 7 have similar problems.)

Uninstall any HP device and try it. Then reinstall the HP device.

Windows 7 64Bit requires signed drivers. Try looking on vendor's website otherwise I am afraid you need to either get a new controller or disable this requirement (not supported by MS)

I have a PSR-E323 and to connect it with my pc using a MIDI connector should i install driver from http://download.yamaha.com/usb_midi/ ??? I tried to install that.. An error msg popped up... error 25001 no device is connected. connect a device and try again. If the "found new hardware" wizard appears push the cancel button...What should I do?? Help me pls...

go to the manufacturers web site and download the driver software for your pc version (mac os, 32 bit 64 bit) windows 32 bit osor 64 os you will find the drivers on theyre support page

In the control panel, sounds and devices, check that the device is in each list under audio, voice, and hardware tabs and that your device is the default device. If NOT in the list, the CORRECT drivers are NOT installed or not properly installed.

You may have to coax it back by unplugging or even trying a different connector on the computer. It may have disabled the port due to a current spike. Using the devoce manager in the windows control panel, see if the port has been disabled. If necessary delete the device and tell it to seearch for new hardware.

Yeah, had that problem too with Vista (I used a 64bit) but it should work in Vista (32 bit) with limitations and Windows 7 32 bit
