To possibly get lower latency for Zquence Studio on Android you can try to change audio settings from AudioTrack to OpenSLES.
First, start Zquence Studio and click on the menu button up on the left.
Click on the Tools button
Next, click on the Settings button
Now, you see the Audio settings directly and there you can choose OpenSLES - Default. You can try to change Buffer size and Sample Rate to see if there will be any different with the latency.
