Power Music Professional was launched at MusikMesse in Frankfurt in April 2014.
Currently, users can upgrade from PM4 to Professional for £29* - saving £20. However, on 28th February 2017 we are closing down the £29 upgrade offer and any user who want to upgrade after this date will have to pay the full price of £49. Don't worry - you will still be able to automatically import all your PM4 songs into Professional.
If you are still using PM4 and want to take advantage of the £29* upgrade offer, follow this link: PM4Upgrade
* £29 is the cost of upgrading a single user licence. The upgrade price for 5 and 10 computer Power Music 4 licences can be found by following the above link.
