Hi - sorry for not being clearer in my reply.

Gearbox is the software editor for the X3L but I don't believe that ever got fully updated to support the JTV changes that were rolled in to the last X3L firmware released. So Gearbox does not allow you to set Variax CH1 or Variax CH2. So I think you need to do that tweaking i the X3L itself - that is how I did it as I never got into the habit of using Gearbox - I was happy to just tweak the box itself.

Here is what you need to do:

1) Connect your JTV to the X3L with the VDI cable.

2) Enable modelling on JTV by pressing the Model knob so it illuminates.

3) Select a patch location that you wish to update or create from new on your X3L

4) Press and hold the INPUTS button on the X3L - this will display your input options for the selected patch for TONE 1 and TONE 2, and whether or not VARIAX control is ENABLED.

5) Select the INPUT option for TONE 1 by rotating the control knob 1 below the display screen. It will give you these choices:

     GUITAR

     MIC

     AUX

     VARIAX

     GUITAR+AUX

     GUITAR + VX 1

     GUITAR + AUX + VX 1

     VARIAX CH1

     VARIAX CH2

     For now select GUITAR + VX 1 which will give you the JTV Variax Model and allow you to put a standard guitar in via the guitar input if you wish. You can select VARIAX CH1 if you only want the JTV model.

6) Leave TONE 2 set to SAME to ensure you get the same input to whatever you have programmed on TONE 2.  The second control knob controls this setting.

7) Check that on the far right the display reads ENABLE GLOBAL CONTROL - if not then rotate control knob 4 to change from DISABLE to ENABLE

8) Use the arrow controls to the right of the display screen to navigate to the bottom half of the display which will display the Variax MODEL and TONE values.

9) This usually defaults to DON'T FORCE MODEL if you have not previously set a Variax model value, and if that is the case, then rotate control knob 1 to change the display to read the first available Variax model which will be the first memory position on your Tyler Variax Custom Bank 1 position 1. You will also notice that the display will now also show TYLER VARIAX V1.71 or TYLER VARIAX 1.82 (depending on what flash level your JTV is at). If you had a V700 attached it would show V700 etc.

10) You can now set the guitar model you want for the patch - either rotate the control knob 1 to select the desired model (which allows you access to Factory defaults as well as User created models) - or use the JTV controls to navigate straight to the model you want.  You will see the display change to reflect whatever you set the JTV controls to. 

11) Set the TONE value to taste - either by using control knob 2 or by moving tone control on JTV.

12) Save the patch using the PRESS TO SAVE button on the X3L.

You are now done.  Repeat this for each patch you want to program in a JTV model change for.

NB: You cannot change the alternate tuning on the JTV from the X3L - in other words you can't select a specific alt-tune on the JTV for the selected model - you can only select the model memory location. You can then apply an alt-tune manually with the alt-tune knob - or select the alt-tune position before changing the X3L patch to have the alt-tune override the model setting.  Or you can use WORKBENCH to create a model with an alternate tuning, then store that in a memory location, which you can then call up from the X3L - but if you do this then make sure the ALT-TUNE knob on the JTV is set to MODEL to allow it to use the tuning in the memory location otherwise the alt-tune knob setting will override it to whatever it is set to - so if you have it on STANDARD but an model in open G you will actually get STANDARD Tuning, or if the knob is set to OPEN D and you have an open G model then you actually get OPEN D - remember the ALT-TUNE knob overrides the model setting unless it is set to MODEL.

If you want the ability to dynamically pick the tuning as well as the model on the JTV then that feature is only available with the HD500, HD/Pro on latest firmware in conjunction with JTV on firmware v1.82.

It is not available for the X3l or the JTV on v1.71 flash.

Hope that answers all your questions. Let me know if you need anything more.

Best Regards

Eddie
