+# AutoSyncHost
+## Description
+### An automatic midi host application that send midi sync commands to other MIDI devices connected via USB.
+
+This python scrtipt is intended to run headless on a raspbery pi but can run on any other python able device as well. 
+
+The output is filtered so the host deosnt receive sync signals from the members and thus not causing midi loops.
+
+## Installation
+ 
+- pull from repository with `git clone https://git.raise-uav.com/Hermes/AutoSyncHost.git`
+- `pip install mido` 
+- `pip install python-rtmidi`
+- `python ashost.py` in folder
+- App is running and waiting for a device playing
+
+## Usage
+- First MIDI device that sends a midi "start" command becomes the host everybody listens to.
+- After hitting stop, ASH has an assigned host and all devices are in sync when pressing play again.
+- Pressing "stop" three times will unbind the host from its duties and restart the app and assignment. 
+
+### Notes
+It is especially interesting for devices that don´t have a physical MIDI port like the OP-Z or OP-1.
