Using Synchro Arts VocAlign 6 Pro is easy. First, load your vocal tracks into the software. To align the timing and pitch of your vocal stacks, you can use the SmartAlign feature which quickly understands where alignment should start and end across multiple clips. For pitch - tuning, let SmartPitch do the work after you've perfected your lead vocal. When it comes to mixing, use the Formant Shift to change the timbre of a vocal without affecting the pitch and Transpose to shift your vocals up or down. Remember to save your favorite alignment settings as presets for future use. In terms of maintenance, keep your software updated to access the latest features and bug fixes. Make sure your computer meets the software's system requirements for smooth operation. If you encounter any issues, check the software's official website for troubleshooting guides.
