If you are referring to Antares Auto-Tune, then it is a matter of getting Antares to "learn" the notes and scales on an instrument playing them. Once Antares learns the scales, you can then remove the instrument, keeping the Antares plugin active in the mixer and assign your vocal track to that mixer channel.
If you like, you can use the Antares basic automated features to decide what scales and notes are needed or not so that any sound playing will tune automatically. This is not perfect, but it does the job closely enough as long as the sound being auto-tuned is not so very out of tune. There needs to be at least some note holding ability. It won't make someone tone deaf sound good, it will only finely tune vocals that are only just out of tune.
Autotune is a vocal pitch correction plug-in made by Antares. FL Studio owners can add on NewTone, a vocal pitch corrector as an online purchase for FL Studio 9, or buy Autotune and run it as a VST plugin.
Roger Troutman used a talkbox, which is a modulation stomp box with a tube sticking out of it that you plug in between your synth/guitar and speaker/amp. It would be nearly impossible to reproduce the sound of a Roger Troutman talkbox in FL Studio, but the best way to attempt to emulate it would be to use an autotune and vocoder plugin. It would be much simpler to buy a $100 talkbox than to spend over $100 on a decent autotune and vocoder plugin.
FL Studio
He uses both
Fl Studio 10
No, .flp save files are opened in FL Studio only, you can however load up FL Studio and use it as a VST within another sequencer of your choice, so you could use FL Studio as a VST within Cubase for example and then load up your .flp project file with all the playback going into Cubase.
Using Rewire, you can host Fl Studio inside Studio one.
The FL studio is only compatible with computers running the Windows operating system so you will need to have a recent iMac with an Intel processor and have Windows installed on it to be able to use the software on an iMac.
Yes
No, FL Studio will work fine without internet access, although you can not use the internet specific features like Collab (used to share music made in FL) and you can't go to the FL Studio forum or upgrade the software. Pretty much like any other software.
FL Studio has an automatic controller preset specifically for that device to use as a controller in the MIDI settings. Though FL will not control the sounds from your device, you can use the device to control FL Studio. Simply select the Keystation as the controller and assign a MIDI port for it to use. Select the Keystation controller type preset to have it set all the knobs and sliders itself.
No, FL Studio is just software.
