Cubasis 3 Android Smartphone and MIDI USB Keyboard compatibility with/without AUDIO/MIDI Interface

Hello,
although Cubasis 3.6.6. works fine on my Xiaomi Redmi Note 9 Pro Smartphone I have not been successful to make Cubasis 3.6.6. respond to MIDI from my external via 5 PIN DIN MIDI IN/OUT connected keyboards (MOTIF XS6 and KORG PA 1X PRO) neither via USB C (Smartphone) to USB A (Behringer UMC 404HD USB-Audio/MIDI Interface) connection nor via USB C (Smartphone) to USB A / USB B direct cable connection (without my MIDI Interface).
Can anybody tell me if I am doing anything wrong regarding connections and necessary adjustments/settings in Cubasis 3 here or if my old keyboards and/or my Behringer UMC 404HD are just not compatible ?
As I only need MIDI (external controller keyboard) at the moment:
Is a AUDIO/MIDI Interface necessary or is a USB C cable connection between my Android Smartphone (Cubasis 3) and an external compatible MIDI Controller Keyboard sufficient for playing a MIDI controller keyboard ?
And what about differences in latency regarding these connection options ?

I also need a smaller full-size keys MIDI controller keyboard.
Is the NEKTAR Impact GXP49 and the NEKTAR GX 49 Controller keyboard or any other similar 49 full size keys controller keyboard compatible with my Cubasis 3 Android Smartphone and is USB power sufficient or is regular power supply needed.

Thank you,
Michael

Hi Michael, I know your post is over 5 years old, but I’m a late adoper in the Cubasis world and only started using it recently. The other day I replied in another thread in this forum with a post that answers your question with regards to the Nektar Panorama P4. You can find it here:Nektar Panorama P4 control keyboard - #10 by e-rik
I recently found out that not all midi keyboards work with my Android phone (Samsung S24) but the P4 does. I tried a Miditech Midistart Music 25 to no avail.

Hi Michael,
Evry Midi keyboard can work on Cubasis 3.6 on your Android tablet or phone but you have to use a Adapter USB C / USB A OTG.
This adapter also allows you to connect a mouse, keyboard, hard drive… to your Android device.
You can found that on Amazon for 10 €.
Have a great day,
Jerry
