Jak w temacie. Nie wiem czy na pewno tam trzeba użyć tone czy co innego

 private: System::Void timer2_Tick(System::Object^  sender, System::EventArgs^  e) 
         {
             Color Lime = Lime;
             Color Red = Red;
             Color Black = Black;
             Un4seen::Bass::Misc::Visuals^ v = gcnew Un4seen::Bass::Misc::Visuals();
 
             this->pictureBox2->Image = v -> CreateSpectrum(tone,
                                 this->pictureBox2->Width,
                                 this->pictureBox2->Height,
                                 Lime,Red,Black,
                                 false, false, false);
