based on the button matrix this script lets you easily create a scrollable area like shown in the video. You can adjust many parameters (and even use custom images for the buttons and scroll bar) by changing a few variables at the top of the script. The relevant code parts are explained in the article as well in case you want to customize it and use it for your instruments. It is recommended that you also read the button matrix article.
KSP: Custom Scripts & Functions (Plugins)
this lightweight script creates a button grid with as many buttons you like. By default there are 4 buttons in a row but you can adjust the matrix (row number and column number) by simply changing a few variables. You can also adjust the button widths & heights, you can position the whole matrix and use custom button images. This matrix is useful to create scrollable areas or a pagination area like selectable tag filters or fx racks (as seen in many modern Kontakt libraries)
In the last article we’ve learned a basic round robin function via groups. Now we create a more complex round robin application. A simple guitar engine, containing 3 different instruments (acoustic guitar, flageolett & fx guitar). They can be activated via special instrument buttons. So this time we nee to create a matrix that only the activated instrument groups are played (containing 4 round robin groups for each instrument)
With samplers (or other software instruments) round robin basically means sound variations. Imagine you are picking a guitar! Your single picks will never sound the same since you always pick the strings slightly different. We can simulate that “humanization” by simply randomly varying between a few sound variations which we all have to recorded of course. So each time you hit a key on your keyboard another sound variation is played. Thereby the same variation shall not be played twice one after another.
