Short answer – Any will do just fine!.
They all have exactly the same functionality. Song Rhythm Tracks app tends to be the first when a new release comes out but the Sampler apps follow shortly afterwards.
Everything described on the website, in the videos, tutorials and user guides applies equally to the Song Rhythm Tracks app and the Sampler apps.
Choose your factory tracks
Each of the apps comes with a different set of inbuilt factory tracks.
Song Rhythm Tracks has about 5 tracks. This helps new users immediately get the idea of the app. They can easily be deleted by swiping each left one at a time and there are only about 5 of them.
Sampler apps have more inbuilt factory tracks, about 20. These are in the genre of the Sampler. There is not much additional cost for these tracks but the tracks might not be the ones you want to play anyway. The idea is that you can ‘sample’ these tracks using the app. You get to appreciate both the sound quality of the tracks and the advantages of playing the tracks using the app. Again, delete the ones you do not want.
Factory tracks sets now available as shared setlists
Each set of Sampler’s factory tracks are now available for download as a shared setlist. To do this
1. Create a new (empty) setlist – press the blue ‘+‘ button.
2. Configure the setlist – press the blue pencil-in-a-box button
3. Name the setlist the name of the Sampler whose tracks you wish to retrieve, either
- Jazz and Blues
- Classic Country Music
- Afro-Cuban Salsa
3. Press the blue hourglass button to search for the named setlist. After a few seconds, your new setlist should get populated with the 20+ tracks of the Sampler by the same name and you will see a confirmation message.
4. Press the blue floppy-disk-button to save the setlist.
You now will have the 20+ arrangements in that new setlist. You can repeat this for each of the Sampler app factory tracks if you wish, using a new setlist for each. There is no cost for downloading track definitions like this. Your allocation of downloads is only decremented when you download the tracks audio by pressing its download button.
Allocation of Download Tracks
The Song Rhythm Tracks app comes with an allocation of 20 tracks before you need to purchase more allocation using in-app-purchasing with the pink shopping trolley button. The sampler apps come with only 4. This allows the sampler apps to be much less expensive. There is no difference between the in-app-purchasing of the different apps. They function identically.
