Driver download i Need the driver for mac for this VST model

All you need to do is download a music program,then your korg will sync and load drivers auto,like flstudio or virtual dj.

Midi is data only, there is no actual sound to the midi tracks themselves. They need to be assigned to either a software synth or an external synth to actually make the sounds you want to hear.

For instance if you load a demo of a midi sequance you will need to add a software synth such as the TTS-1 or Roland sound canvas which are general midi compatable and will play the instruments sounds assigned to the demo's midi channels. Use the Synth Rack feature in Sonar to open one of them. Then you will need to assign the output of each of the midi tracks to that particular synth and you will get sound. Make sure to assing the synth's audio track to you UA-25 as its audio output.

I would suggest reading in the manual and following the tutorials included in the manual to get yourself familier with how this is all done.

In cubase go to "Devices", there select "Device Setup", in the Device Setup windows go to "VST Audio System", on the top right you will see the "ASIO Driver" drop down menu, click it and select your sound card from the list. Also take a look into VST Connections.

How to use USB device like a USB microphone, or USB guitar Cable in CubaseThis was a frustrating problem for me and I found most forums did not really helpAfter hours of annoyance I finally figured it out and it's a very easy and quick fix.1.Download free ASIO4ALL 2.8 here http://download.chip.eu/en/ASIO4ALL-2.8_108174.html and then restart cubase2.Click Devices and Open Device Setup3Click Vst Audiobay and Change the Master ASIO Driver to ASIO4ALL v24.Underneath Vst AudioBay Click ASIO4ALL and Click Control Panelhighlight All devices you wish to use and Enable them.5.Still in Device Setup hit VST Inputs and check to make sure all Devices are there6.Exit Device Setup and under the Devices open VST connectionsClick add bus, and Add Busses. Your Sound Device should be the first Bus that pulls upand the other busses will automatically be whatever the USB Devices you enabled were.7.Last thing and very important, when you open up a new Audio track Right click where it shows Stereo in. Your usb devices will start at stereo in 2 and depending on how many you enabled go up in numbers from there.In my particular case I have a Blue Snowball usb mic as my first Device (stereo 2)and a Usb Guitar Cable interface as my second device (stereo 3)*If you would like to hear and test your sound prior to playback simply click the monitor button and unclick it at playback.That simple, there you go.This will work, takes and takes less than a minute.

PLZ UNINSTALL NUENDO FIRST. THEN INSTALL MOTU DRIVER. NEXT POWER MOTU.

NOW YOU CAN SETUP MOTU AUDIO.
OK

A relatively straightforward answer is that the AT4 is not VISTA compatible.

AT4 is not VISTA Compatible and has issues with XP 64bit. It is only guanteed to work with

Its compatibility list is as follows

DirectX
on Win 98, ME, NT, 2000, XP
@ V4.3.9

VST Mac
on Mac 10.2.6 or later
@ V4.3.9
VST PC
on Windows XP
@ V4.3.9

Unfortunately, we live in a disposable society, you can easily find a brand new mac compatible usb floppy drive for under $50.
It would certainly take several hours and spare parts to repair your drive... :(
