Rolf Holmberg has added a neat MIDI switcher pedal to his eTap2hw ‘EchoTapper’ setup to allow him to change presets easily during a gig.
The Gecko MIDI Switcher pedal by One Control is a great solution for quickly switching between programs on midi devices. It has two modes of operation:
Manual mode – allows guitarists to scroll through midi programs one by one. Use the up or down switch to scroll through programs and once a desired program is reached, hit the select switch to choose the program.
Preset mode – allows you to save 8 presets from 0-127 and scroll through those 8 only. This would probably be the most useful mode for us Echotappers as a carefully chosen set of 8 presets would cover most Shadows tunes in a ‘live’ situation.
In order to upload the EchoTapper Automation code (contained in a HEX file) to the Arduino UNO microcontroller in your EchoTapper unit, it is necessary to connect the UNO to your computer via a USB cable and run a suitable uploader tool.
As users (including myself) have recently found, the original uploader tool that I recommended no longer works. This may be failing due to an incompatibility with the version of .NET installed on the users pc.
I am now recommending users to download and use XLoader and use that to upload the code to your EchoTapper. XLoader can be downloaded here.
These are the default settings for the Uno and they seemed to work fine.
When you run it choose the Uno option from the Device list, select the COM Port that your Uno is connected to, leave the Baud rate at the default (115200) and click the … button to browse to the hex file you wish to upload, then click the Upload button and a few seconds later your software will have been updated and the EchoTapper will restart – check the version number displayed to make sure everything went ok.

Update 24th October 2013: Some bug fixes and extra features added. The links below now point to the latest Version (2.3) of the Editor/Librarian. The EchoTapper Version 3.20 Arduino code has not been changed so there’s no need to update your eTap2HW hardware. I’m looking for anyone using my Automation software with their eTap2HW-based echo units to try out this preliminary release of a software application which I am calling the EchoTapper Patch Editor/Librarian. I have written it in response to a number of requests from users of my automation code to enable them to back-up and re-arrange their User Patches, for example to create personal set lists. Although not yet having all the planned features included, the current version allows patches to be transferred to and from the eTap2HW via the USB connector on the Arduino Uno, and it also allows them to be saved to and loaded from disc. In it’s Editor role the software allows patches to be renamed and fully edited, for example, by changing the echo model and adjusting the echo parameters. It simulates the three main knobs on the ‘real’ eTap2HW control panel. In order to use the Librarian with your eTap2HW you will need to upgrade the EchoTapper automation software to version 3.20 or later. The Librarian requires you to have Java installed on your computer and versions of the Librarian are available for Windows 32, MacOS X and Linux. As I don’t have access to MacOS X or Linux, these versions have not been tested yet and the Windows version has only been tested on Windows XP Professional. I would appreciate feedback on the software running on any of these operating systems so if you are able to help please download the relevant version and leave your feedback in a comment, remembering to state what OS you are using and details of your experiences and suggestions for improvements, if any. Thanks and enjoy 🙂 PhilipLibrarian User GuideAutomation Software Version 3.20 (There seems to be a problem with the old upload tool I previously recommended so please try XLoader which is available here and is very simple to use.)

For those who would like to update to the current presets without changing to the latest automation software here are the revised settings for each of the original presets. You can use Basic or Advanced Editing to modify the original settings in the User Patches. Basic edit is sufficient as we didn’t change any of the Echo Model settings or patch names.
