Excellent sound quality, unique approach and old school charm. This is a great ap. The only thing that caused me to give it less than 5 stars is the non-standard interface, which appears to be derived from the fact that this is a generic program available in several operating systems as opposed to having been created exclusively for the ios. I have the program on my mac, but the iPad version is better to work with.
Look up the details on the historic ANS instrument to get where this ap is coming from. Its very interesting and reveals the aps old school inspiration. The ap is worth every penny, but its not for pop devas or those who want to "produce" yet another rap with the usual boring, formulaic 4/4, synchopated backbeat drum track at 120 bpm. This goes a totally different way.
