LAZY DJ , AUTO DJ , AUTO TRIGGER. I know some people don't like this type of product,but remember not everyone is a dj. this is a useful tool when you are busy and can't dj,but want to hear music from your trigger tunes inventory or sets. this isn't meant to replace real djs. I hope people will like and use this tool. it only works on whole or half seconds at the moment so if your music isn't cut to whole or half second intervals this will not be a good tool. try before buying :)
