Feature:
The main advertised feature of this product is to remove the main vocal, which is why the manufacturer has since re-named this product "No Voice". I think it's a great product, but I think the product name is slightly wrong since it doesn't completey remove the main vocal. What it does is SUPPRESSES the main vocal to a point where you can barely hear it....but depending on the recording, you WILL still slightly hear the main vocal in most cases. However, the product does a very good job in masking / suppressing the majority of the vocals. It makes it a great product also for being able to hear background instrumental parts and vocal harmonies that exist on the original recording that you may not otherwise pickup on. So it's a great product for that as well.

Quality:
Overall quality of the entire product is good, but not excellent. There are certain windows which appear with basic instructions, and the text didn't fit well within the window(s), causing part of the help to get cut off. I tried re-adjusting my screen size/resolution, but it didn't fix it. The messages do appear though, at least well enough to get the message across. I wouldn't let this minor flaw stop anyone from buying the product, as it does not effect the products performance. There is not a printed manual, but there is a pdf file which can be printed out to provide more detailed directions on using the software.

Value:
I would definitly recommend this product to anyone with musical interests, and even moreso to anyone who sings and plays an instrument in a band. I think the manufacturer may be disappointing many karaoke singers / purchasers by calling this product "No Voice" and claiming vocal REMOVAL. That sets them up for disappointment and bad reviews when people get the product home and realize the main vocals are still slightly there when the effect is applied. If they advertise vocal SUPPRESSION, I think people would understand it's not going to completely remove the vocal, and would be more accepting of the product and not have such high expectations from a $30 piece of software.

Sound:
Given the fact that MyVoice needs to process changes, I did not expect perfect sound quality. The sound quality is great when playing the original music, and can be average to good after making various changes to the sound (it depends what those changes are). I play professionally in a band and acquired this software to assist in masking vocals, slowing down parts, and to help me find the best key to sing a given song in (transpose feature). This software easily accomplishes all of that.

Ease of Use:
Extremely easy to use product compared to some other software I've used which did a few similar things. Slider controls make it easy to adjust various settings.

Support:
This is actually "Not applicable" because I haven't needed or tried to contact the manufacturer for any reason as of this writing. But the drop-down box in this review forces you to choose a number, so I'm giving somewhat the benefit of a doubt to the manufacturer and providing an unsubstantiated "8".

Overall:
It's a tall order for ANY priced software to completely remove pre-recorded soundtracks from an original recording, which is probably why there are few pieces of software out on the market claiming to do this. HOWEVER, "MY VOICE / NO VOICE" DOES AN EXCELLENT JOB FOR THE PRICE, COMES THROUGH ON THE MAJORITY OF WHAT IT CLAIMS TO DO, AND I AM HAPPY I PURCHASED IT (& would re-purchase it if I ever had to!)
