Synchronization refers to the app loading data from your Kronos to be able to show you values and names just like they show up in your Kronos. The app comes with the Kronos factory data preloaded so you can see some useful content instead of blank screens, however you probably have your own programmed presets or own setlists stored on your Kronos that you want to be displayed on the iPad.
If you select a preset from within the app, it will sync automatically as soon as you hit ‚Commit‘ and thus ensure all settings match the ones on your Kronos screen.
Each preset on the Korg Kronos features a huge number of parameters – these take some time to load and synchronize within the app, so for a better user experience presets that you change on your Kronos are not automatically synchronized. This is to account for fast preset changes on the Kronos (scrolling through your presets) which otherwise might slow down the app for quite a while. Instead a ’sync‘ button will appear just next to the preset name title bar – simply tap this button and the app will sync all preset parameters to your Kronos.
Unfortunately we can’t load ALL data onto the iPad and always keep it up-to-date, it would just take too much time and keep you from working properly, so here’s how it works instead.
The important things to keep in mind, assuming you’re on a USB connection:
- Preset and setlist names are always synced – disconnect the Kronos and you still see your presets in the selection list on your iPad
- Setlists can be synced manually – disconnect the Kronos and you can still access every setlist on your iPad
- Preset data (parameter values) are only synced for the currently selected preset and overwritten by the next preset if you change – disconnect the Kronos and the parameter values will be the ones from the recently selected preset, even when you change the preset on the iPad
Preset names (including setlist names): On connection the app will check if any banks need to be synchronized and will load all relevant preset / setlist names to your iPad. They are stored and will be still visible after you disconnected the iPad or even finished the app. This means once you had the app connected via USB cable and synched, your preset names and setlist names will be stored in the app until they’re updated on the next connection.
Preset data: each sound preset consists of a huge amount of parameters like level settings, cutoff frequency, FX settings and so on… if the app would copy all these data on connection (like it does with the names mentioned above) it would take many minutes to copy everything each time you want to use the app – that’s not something you want to wait for. Instead if you select a preset on the Kronos the app will display the selected preset and give you a ’sync‘-button next to the preset name. So you can decide if and when you want the data for the currently selected preset copied to the app. If you press that button you see a progress bar and after a few seconds all your parameters will update to the actual Kronos settings. Btw this happens automatically if you use the app to select another preset.
Setlist data: setlist data contains the information which presets are contained in a setlist, the colors of the slots, the comments and everything setlist-related. It’s basically the same as the preset data mentioned above – but since it’s only 128 setlists (compared to more than thousand presets) the app offers an option to copy and store all setlist data into your iPad. You find it on Global > Sync > ‚Load all setlists‘. Once you pressed this button and waited for the process to end, you have all setlists stored on your iPad – you can now disconnect the USB cable, connect to your Kronos via Bluetooth and have wireless access to all of your setlists on stage (remember: the Bluetooth connection doesn’t allow synchronization, so the iPad would still show the factory setlists instead of your actual setlists).
