Minor Update to BN Librarian

I’ve noticed that a few people, myself included ;-), sometimes forget that, when uploading  new DSP code, the Blue Nebula must be powered from the 12V DC supply input. If you only have the USB cable attached it will appear to work but in fact the new code will not have been uploaded – only the effect names will have changed.

(Technical note: this is because the USB cable only powers the microcontroller and the LCD in the Blue Nebula but the memory chips require 12V from the DC input jack).

To try to avoid this confusion, I’ve added a reminder message that will pop up when you click the Upload DSP button:


Once you click OK the usual file selector dialog box will open and you can proceed as normal.

This Version of the BN Librarian is 4.04 and, as always, you can download it from the ‘Latest Updates Here’ link at the top of this page.


Librarian Update to 4.01

Reminder: You need to have Java installed on your computer to be able to run the Librarian. If you have the 32-bit version of Java you will only be able to run the 32-bit Librarian even if your OS is 64-bit. If you have a 64-bit Windows Operating System, please check this page for information on which version of Java you should download if you don’t already have it.

Librarian Version 4.01 is an update that fixes a bug in the previous Version 4.00.

The bug prevented the Librarian from correctly interpreting the ‘Heads’ data sent by the Blue Nebula for emulations with numbers between 5 and 15 that use the ‘coded’ ‘A’, ‘B’, ‘C’, ‘E’ and ‘F’ values. It caused the wrong head letter to be received by the Librarian and all head settings became ‘A’ instead of the correct letter value from the Blue Nebula patch. This incorrect value would have been saved in any patch files saved with the Save Patches button in the Librarian. If this patch data was subsequently sent back to the Blue Nebula using the Send All Patches button it will have corrupted the heads value in the Blue Nebula’s patches. You should check and correct the Heads settings in any affected patches and resend them to the Blue Nebula.

The Blue Nebula Firmware 3.02 does not require a fix for this bug, only the Librarian.

The updated software can be downloaded from the Latest Updates Here link above.

Make sure you download the correct version depending on your Windows Operating System: 32-bit or 64-bit. The 32-bit Librarian will work on 64-bit Windows systems but the 64-bit version of Librarian will not work on a 32-bit Windows OS.

The update for Mac OSX will be available as soon as possible.


Firmware Update 3.30

These updates are like buses, none for ages then two come along at once! This one features a nice little improvement to the Manual Mode display suggested by Rolf Holmberg. It now shows the function of each of the three pots so you don’t need to remember what each one does. For anyone not familiar with the eTap2HW effects designed by Piet Verbruggen, the function of the three controls can vary depending on which echo model you have selected. Click on the ‘Latest Updates Here’ link in the menu bar at the top of the page.

The new display is shown in this quick little video I made. Video

Librarian Version 2.50

Thanks to Rolf and Steve for testing Librarian on Windows XP and Windows 7. We discovered a problem in that if there was only a single enabled COM port on the user’s computer the Librarian failed to connect to the attached EchoTapper. This has been resolved in the latest Version 2.50 of the Librarian and we can confirm that it works on Win XP and Win 7.

Click here to download the Windows (32 bit) Librarian version 2.50. The package should be unzipped to any convenient location on your computer where you will then find a folder called application.windows32. Open this and double click the .exe file to run the Librarian.

  1. If the Librarian only detects a single active COM port when it starts it will attempt to connect to it. If this is your Arduino then it will reset the Arduino and contact will be established. You can hit the EchoTapper’s Down button (or turn the encoder CCW) during the Welcome message or just wait and hit the Librarian’s Get Patches button to transfer patches from the Arduino to the Librarian.
  2. Of course it’s possible that you haven’t connected your Arduino yet so there may be a COM port but not the Arduino’s port. In this case the attempted connection will obviously fail. To update the list of COM ports hit the new orange Re-scan button (see screenshot) and you should now see a new port in the list which will be the one that your Arduino is attached to. Now select it from the drop down list and the connection will be established between the Librarian and the Arduino. As in 1, you can hit the EchoTapper’s Down button (or turn the encoder CCW) during the Welcome message or just wait and hit the Librarian’s Get Patches button. Please ensure you do not click the Re-scan button while your Arduino is still starting up after plugging it in as this may cause problems. Wait until the Welcome message has disappeared and the Arduino is then ready to rock and roll 😀
  3. If the Arduino is connected when you start the Librarian and you have more than one COM port, the Librarian will not attempt to make contact as it won’t know which COM port it should use. In this case you must select the correct COM port yourself from the Drop down list and this will initiate contact with the EchoTapper and you can then proceed as before.
