Piano Models

Colossus Piano provides up to 8 acoustic piano models and 5 E-Pianos, so these are up to 13 piano models in total. All of these piano models are available as optional in-app purchases within the Colossus Piano app.

Managing Piano Models

Installing all these piano models of Colossus Piano can take a large amount of your iPad / iPhone's SSD space, which would be more than 30 GB on your iPad / iPhone if you installed all piano models at the same time, and since this may indeed be a problem especially for older iOS devices with limited SSD space, the Colossus app provides a dedicated piano models screen where you can install and uninstall individual piano models at any time. So if you are ever running out of SSD space on your iPad / iPhone and need to make space for some other purpose, i.e. for downloading another app, then you can also temporarily uninstall individual Colossus piano models and eventually re-download the piano models at any time later on.

You will never be charged twice for re-downloading any of the app's piano models (in-app purchases). Just make sure that you are logged in on your iOS device with the same Apple ID that you used before when you bought the piano models for the first time, and the App Store will always detect that you bought the respective item before and will offer you the download for free instead.

Buying a Piano Model

To buy a piano model, first tap on the piano model's "Details ..." button. The selected piano model's preview screen appears, showing you a description as summary of the piano model's features, along with a demo video. Tap on the white play button to watch the demo video of the piano model.

If you want to buy the piano model, simply tap on its price. The App Store will now prompt you a dialog, asking you whether you really want to buy this item now. Confirm this question to complete your purchase. After tapping on the price, it may happen sometimes that the App Store may take a moment to respond. So after tapping on the price simply wait for a moment. You don't have to tap on the price again.

Finally the App Store will confirm your purchase and the piano model starts to download in the background. On the piano models screen for instance you will now notice that the piano model's status changed from "Not installed." to "Downloading ...". And on the app's main screen you will now see a progress indicator and status message of the piano model currently being downloaded. It may happen, especially with the largest dark brown "Colossus Concert Grand" piano model (14 GB), that after you purchased a piano model, that it may take several minutes for the actual download to start and that you may see messages like "Preparing package ..." and "Reconnecting ..." appearing on the screen for the first couple minutes. There is no user intervention required whatsoever. Simply leave the app running for a while and the actual download will start automatically after couple minutes.

Uninstall Piano Models

Like previously mentioned, you may re-install piano models at any time without being charged again. And in case you need to free some SSD space on your device for other purposes, you can also uninstall individual piano models at any time.

To uninstall a piano model, simply open the piano models screen, like shown above, then tap on the respective piano model's "Uninstall" button to delete the piano model from your iPad / iPhone for now. The app will prompt you a dialog, asking you whether you really want to delete the piano model now. Confirm this question and the piano model will immediately be deleted.

Restoring Piano Models

There are two ways to re-install piano models that you have purchased before. You may either ask the app to automatically restore all piano models that you may have purchased before, or you might rather want to just restore only specific individual piano models instead.

It may happen that the App Store first asks you whether you really want to "buy" this item now at this point, even though you already own the piano model. Don't get confused about this. As soon as you confirmed the question the App Store will immediately detect that you already own the item and will offer you the download for free instead. Like previously mentioned, you will never be charged twice for any piano model that you bought before.

Download Progress

Since the individual piano models can be quite big (between 1 GB and up to 14 GB), there are additionally ways to control the status of piano models currently being downloaded.

Progress Bar

While your piano model is downloading, you see a progress bar on the app's main screen and a status message. As some of the downloads may take a while to complete, there is also an animated green arrow, next to the progress bar, which symbolizes incoming data packets from the Internet in real-time. This makes it easy to recognize whether a download is actually still active or whether there are sometimes interruptions concerning the incoming download data stream.

So as long as you see the green animated arrow, everything is Ok, the download is active and the piano model is automatically installed once the download completed.

If you no longer see the animated green arrow for a long time (i.e. more than several minutes), then please check your Internet connectivity. The app is designed to automatically resume an interrupted download without any user intervention. So once the Internet connection became available again, the download will automatically resume at its last position.

Pausing Download

You may also pause an active download, i.e. when you got to leave the house and have a cellular access which charges you based on the data volume you consume. In this case simply tap on the download progress bar shown above. A dialog appears asking you whether you really want to pause the download now. Confirm this question to pause the download.

Once you are back at home, or another place with WLAN connection, you can easily resume the download by tapping again on the download progress bar and the download will immediately resume at the position where it stopped.

Automatic Resume

Like previously mentioned, the app automatically handles resuming interrupted downloads without any user intervention required. Especially cell phone based Internet connections tend to interrupt frequently, so this is a normal circumstance the app automatically deals with on its own. There is no need to sit and wait in front of your iPad or iPhone for your download to complete.
