Transportation Issues with launchkey MK4

[Mister Mike]

Hi out there,

there is a latency starting the sequencer / sequence around half a second. Stop reacts imediately.
GSTP won´t start on the first step regardless of what I change in the Setup/Midi Parameters.
I tested nearly all of my Midi Controllers, which are working fine with all the cables and other
USB stuff I use on android for e.g. Cubasis

No issues there. Love the app (after seeing Caustic dying) and without any controllers, everything
works like a charme. This app cries for live action but without a nearly half secure controller this
won´t function.

Global CC Mappings for transportation = same issues

Version
G-Stomper Producer

Tested Gear
Samsung S6 (not the light one)
Huwai Media Pad T5
Xiaomi Pad6
Samsung S10 mobile

splitted USB C Dual cable (USB Power + OTG function).
D-Link powered USB Hub Dub H7

Any Ideas, what´s going wrong ?
I know, Android is wasted land in terms of compability.
But maybe there´s hope for me

Kind regards

Thanks for your message. This comes from the audio latency of your device. You can compensate it using the latency compensation slider in the MIDI settings.

Main screen / setup / midi / latency compensation

Depending on the selected audio system (main screen / setup / aud / audio system), the audio latency might be higher or lower. Recommended for lowest possible latency is AAudio.
