I haven't heard of that brand or seen that model before. Ever since "The ONE" released their marketed-as-a-new-idea hardware a few years ago, it seems like these competitors have been coming out of the woodwork.
We've added a few more proprietary key light schemes lately. So if these Terence people copied any of those other keyboards, it should work. But you'd be the first one trying it out that I've heard about.
- Turn on Bluetooth in iOS « Settings »
- Pair the keyboard with the « MIDIMittr » app (or « BLE-MIDI » by Korg)
- In Synthesia app (10.9.2 with iOS 9.3.5) :
Go to Settings
→ Choose the keyboard
« TERENCE piano » from the Music Output list
→ Key Lights
→ Scroll down
→ Choose « Proprietary format 3 Vangoa »
