What is Sonorasaurus Rex?
Sonorasaurus Rex is a complete deejay setup for the iPad. Sonorasaurus includes two independently controllable decks and a mixer with built in effects. Additionally Sonorasaurus Rex has an interactive waveform display and in-app recording.

What’s with the name Sonorasaurus?
We love dinosaurs. In addition to the Sonorasaurus being a large dinosaur it is also a play on words in that it references the ‘sonorous’, which means to produce a full or loud sound. In saying that we hope to help deejays make a musical impact with the Sonorasaurus applications.

What audio formats does Sonorasaurus Rex support?
MP3 (128 – 320 CBR or VBR), AAC or WAV

Why can’t I access my iPod library with Sonorasaurus Rex?
Apple currently has restricted this type of access for applications like Sonorasaurus Rex on the iPad. The restriction may be lifted with the release of os4.2 this fall. If so we will bring in iPod library connectivity in a future update.

How do I upload songs to the iPad using iTunes File Sharing?
1. With your iPad connected to your computer via USB open iTunes.
2. Select your iPad device in the left column of iTunes and navigate to the Apps tab.
3. Scroll down to the bottom of the Apps area and you will see the File Sharing menu. Sonorasaurus will be visible in the list here and once you select it the Sonorasaurus Rex Documents box will appear to the right.
4. When adding files you may also want to add them in batches. You can use the same multiple file selection commands as you would on the desktop like holding shift or command clicking.
5. Once your files are selected and confirmed they will immediately begin syncing to your Sonorasaurus Rex Users Library.

How do I upload songs to Sonorasaurus Rex if I am not able to use iTunes or don’t have a USB cable handy?
Sonorasaurus Rex also has the HTTP Server option in the settings as an additional way to get tracks into your library. The following outlines how it works:
1. Make sure your iPad and computer with the songs you want to add are on the same WIFI network.
2. When you are in Sonorasaurus Rex click the ‘Settings’ button to access the HTTP Server.
3. Turn the HTTP Server ON and you will be given a unique address.
4. On your computer, type the unique address into a browser like Safari or Firefox.
5. A file upload screen will load in your browser window.

What is the Featured section in the library?
The featured section contains songs we think you will enjoy, and also allows for you to immediately try out Sonorasaurus Rex before you have a chance to upload your own tracks. Some people have asked if they can delete these songs. The answer is no. The way they appear now is a compromise so that we can deliver the app with music included to enable users to immediately try out Sonorasaurus Rex’s features. Any other method of inclusion and potential removal could be seen as a way to circumvent the iTunes store in delivering music to users. We understand that after people have set up their own libraries they will only want to see their tracks so in the future we may include a hiding option with an update.

I don’t want to create waveforms for my tracks one by one. Is there a better way to create them for my library tracks?
Yes. We have a batch waveform creation option. In the library you will find a ‘Pre-processing’ option under Utilities in the left column. When you select this you will see a new screen giving you the option to create your waveforms all at once. The process does take a fair amount of time to run depending on how many songs you have in your library without waveforms. It is recommended that you use this feature when you don’t have to make a mix or play a gig at that point in time.

How do I create a playlist and add songs to it?
1. While in your library tap the + button on the Playlists bar in the left column.
2. A new list item will appear called ‘New Playlist’. Hit Edit on the Playlist bar to rename this new entry whatever you like.
3. With your newly named playlist created, view your user tracks.
4. Add songs to your playlist by dragging them over by their file icon to the left of the song title.

You can also change the order or delete any songs in your playlists at any time by tapping Edit in the top bar while viewing a playlist.
