BMDSwitcherMIDIMapper is a simple tool which is able to control ATEM TV Studio by BlackmagicDesign through MIDI devices. We notify you that we accept NO warranty or liability for this freeware. Before using it, you need to write down IP address with ATEM Setup Utility etc. because the information is required to connect this application to ATEM. You are recommended to update your drivers around ATEM Switcher to the latest version. Though it is not necessary, some bugs may be fixed on the latest version. Please start this application after installation of MIDI device driver you need, and connection.

- How to configure -

* Connect to ATEM

ATEM Switcher IP Address: Input IP address of ATEM to connect. Next, push "Reconnect" button to make connection to ATEM. In case of any problems, a message box will be shown.

# Do not launch ATEM Software Control before this application starts up as due to scramble for MIDI devices you may not be able to catch up signals from MIDI devices.

* Connect to MIDI devices

MIDI Device: This pulldown menu displays the list of connected MIDI devices, where you can choose MIDI devices you want to use.

# Start-up after completing connection to MIDI devices and stand by applying current otherwise they are not recognized.

* How to assign MIDI signals to each function

Version1.00 allows you to map MIDI signals onto options of Tbar, Auto Transition, Cut, FadeToBlack and ProgramInput (max # 5), or choice of PreviewInput (max# 5). First, move the knob, the PAD or the slider on MIDI controller you want to use, and make sure that received signals appear on MIDI Monitor. Confirm reception before you choose a function you want to map out of Function pulldown menu, and click the "Attach" button. When you release assignment of each function you set up, manipulate the device to receive MIDI signals you need to release. Click "Remove" button after confirming a relevant signal is received.

Data related to assignment will be saved as file in the same directory as this application.
