Hi
I have a few workarounds that might help you.
======================================================================================================================
Method 1 (This method will allow you to assign each of up to 23 buttons on your control surface to a matrix cell.)
======================================================================================================================
1 Create a 12 X 12 matrix. Assign both X & Y to the same controller (a controller you won't be using for anything else.)
2 Arrange all Matrix control bars for the X axis to fit into the left half of the X-axis grid.
3 Arrange all Matrix control bars for the y axis to fit into the right half of the Y-axis grid.
4 Be sure the right most control bar in the X axis is to the left of the left most control bar in the y axis.
5.Place the articulations you want to use in the top row and in the last column of the matrix.
Now simply assign each button on your midi control surface to send a controller value using the controller you assigned in step 1.
The approximate values will be something like the ones below. The values will vary slightly depending on the spacing of the matrix control bars.
Button 1 on your control surface = Send CCx value of 0 (Selects Matrix cell A1)
Button 2 on your control surface = Send CCx value of 3 (Selects Matrix cell A2)
Button 3 on your control surface = Send CCx value of 7(Selects Matrix cell A3)
Button 4 on your control surface = Send CCx value of 13(Selects Matrix cell A4)
Button 5 on your control surface = Send CCx value of 22(Selects Matrix cell A5)
Button 6 on your control surface = Send CCx value of 26(Selects Matrix cell A6)
Button 7 on your control surface = Send CCx value of 36(Selects Matrix cell A7)
etc...
Button 11 on your control surface = Send CCx value of 57(Selects Matrix cell A11)
Button 12 on your control surface = Send CCx value of 62(Selects Matrix cell A12)
At this point, you will be at the end of the right edge of the matrix and the
numeric values will start moving through the Y axis so the direction is down
the control.
Button 13 on your control surface = Send CCx value of 70(Selects Matrix cell B12)
Button 14 on your control surface = Send CCx value of 82(Selects Matrix cell C12)
etc
How it works...
When you press buttons that send lower numeric values, the y axis remain static at 0
so as you increment numerically the cells move left to right in the same row,
because of the arrangement of the matrix control bars.
When you reach the middle numeric values, those values effect the y axis while X axis remain static at a
value of about 62... again this because of how the matrix control bars are arranged.
This method will waste most of the matrix cells, but who cares. You will be able to select one articulation per button.
...up to 23
I've been using this method for some time. Once it is setup it's seamless.
I worked this out so I could play with my right hand and change articulation easily and intuitively with my left hand.
If this is confusing, I could insert a screen shot of the matrix X/Y axis grid, if someone would kindly tell how to insert a graphic image.
==================================================================================
Method 2 - This will allow you use up to 128 buttons to select 128 articulations
=================================================================================
Simply add up to 128 matrices to a preset.
Make each matrix consist of only one cell.
Assign each button on your midi controller to send a program change.
Button 1 send prog change 1 to select matrix 1.
Button 2 send prog change 2 to select matrix 2.
Button 3 send prog change 3 to select matrix 3.
etc
I would be interested to hear feedback on these methods. Are they flawed in some way that I have overlooked?
