UTILIZATION

Pretty simple to use, the manual is sufficient that the one must remain vigilant with harmonies to use, but it is not in it nor a mode of employment ... Easy editing, it should be somewhat familiar with the machine to know where you are.

SOUND QUALITY

That's why I wanted to leave a review ... The effects are a little robotic ... but ca not be interesting. Be that as it is to be used sparingly because it is quick to find the singer's voice "bizarre"
Finally be careful because when the input signal is a little weak the harmony is no longer ... expect long tests with compressor reduce support for al this (you do not completely by ridding)

OVERALL OPINION

I think for a small budget c is interesting provided you do not abuse it and thoroughly familiar with the device in order to delete some of these defects. If not for serious use it is better to save a little for something more efficient.
Other than that the color is terrible!
