During Madonna's Confessions Tour, she uses the Access Virus TI Polar synthesizer, as seen in the YouTube video by M Videos2.

Madonna utilized the Clavia Nord Lead 2 Synthesizer for the main bass line in her song "Hollywood." The meticulous attention required for controlling the filter and ensuring expressiveness in the bass-synth sounds from the Nord Lead 2 was highlighted in a source, where it was noted: “You have to be very careful with the controller and the way the filter is used. With bass-synth sounds [from the Nord Lead 2], if you don't use the legato, if you don't add expressiveness, it is very static-sounding. This is why some electronic music is very cold. For the main bass line in ‘Hollywood,’ you can't imagine how long I stood there with the controller.” This information is documented in the article "COVERT Operation" from Remix magazine.

Madonna is confirmed to use the Access Virus TI2 Polar, as evidenced by a photograph showing her in the studio with producer Stuart Price, where the synthesizer is visible in the background.
