Hello Rossi,
Kiosc adds a user interface to the CueCore1 and QuadCore. Which is a way to tell them what to do. And a way to show you what they are doing.
You can use the API of the QuadCore with Kiosc. Or you can use show control of the CueCore1 and QuadCore. However both the CueCore1 and QuadCore do not support a tempo button.
The QuadCore does have a playback rate. Which allows you to speed up or slow down a playback.
I hoop this helps.
Best regards,
Guido
