Just Piano

GSi JUST PIANO is a sample-based acoustic piano player, built around the powerful WLF Engine that ensures low latency, low memory and high Direct-From-Disk streaming accuracy. In order to play this instrument, it is necessary to download one of the Piano sounds made available by GSi. When the App is run for the first time, an alert invites you to make your choice and start downloading the sample data. Downloads can be rather large, between 1 and 4 GB according to the chosen piano sound. Only one piano can be installed but can also be replaced at any time. In case new piano sounds are made available by GSi, these will be be added to the catalog.

If you want to download more samples and keep them all on your device to switch between them at any time, check out our other app: "Genuine Sounds Vol. I - Piano Edition" which allows you to download up to 40 GB of piano samples of all kinds.
