Similar to Long Discontinued MP-VT1,
I have the MP-VT1 version of this which has been a wonderful tool for learning vocal parts.
The functions I used on this (all the time) were:
* Vocal Elimination (standard Left Right Subtract with optional BandPass filtering)
* Changing the key of the track to find the sweet spot or to temporarily compensate for not being warmed enough for the high notes
* Slowing down to figure out a fast run or embellishment
* Speeding up a track slightly above performance temp for practice... then when it's performance time I feel more confident (that feeling of "it may be a little fast but I know I could do it even faster if I had to
There are effects I rarely used so I won't comment on those.
This CD-VT2 vs my MP-VT1:
* The MP-VT1 had a very small memory (by today's standards) for music. Sometimes that was good (no CDs needed) but at other times I was struggling with reducing bit rates or with what tracks to delete in order to have the most essential tracks loaded. With this CD version you're only limited by the number of CDs you're willing to carry.
* The HUGE advantage of this device over mine is that the key, tempo, etc controls are _dedicated_buttons_. On my discontinued device you had to go through nested menus to control the tempo or key which sometimes interfered with the flow of my practice sessions.
* This has two mic inputs vs the older device's one
!!! If I didn't already own the MP-VT1 I would buy this without any hesitation !!!
