CTR2-Flex/CTR2-Dial firmware release v2.03.04

----------------------------------

This zip file contains four firmware .BIN files that are used to flash the CTR2-Flex firmware on CTR2-Dial or CTR2-Flex hardware. 

Windows and Mac users can use ESPLaunchPad, a browser based flash download tool. For more information see https://ctr2.lynovation.com/espressif-browser-flash-download-tool/ 

The CTR2-Flex_install.sh file is a script that you can use to install the firmware on your CTR2-Dial/CTR2-Flex without the need of the EspressIF Flash Download tool. This file is most useful on Linux and Mac PC. 

>>> If you use the script file remember to make it an executable file. <<<

To download these files to your device, extract them into a folder then use the instructions in Appendix A: Install or Update CTR2-Flex Firmware section in the CTR2-Flex Operation Manual. 

NOTE
============================================================================================================================================
This version contains both CTR2-Flex and CTR2-Dial firmware, therefore, operation manuals for both firmwares are included in this zip file.
I've also included MIDI map files for CTR2-Dial and the 3rd party apps it can control.
