Lemur iOS can connect to your Mac with the USB sync cable that is included with your iOS device. This enables MIDI communication via the Daemon, and editing/loading templates via the Editor.

Android 6.0 (Marshmallow) supports USB MIDI, and so does Lemur (versions 5.3.3 and up).
To enable USB MIDI, plug your Android tablet to your computer or MIDI device with a USB cable.

However, my preference, in combination with windows, lies with a wifi connection. That is the simplest and stable connection so far.
