Hello Jim
Thanks for the kind words about my tutorials.
About the use of controllers
The most natural sounding music with samples (when not played by a music program) is when you play short notes (e.g. staccatos) using the velocity of the keyboard and control the volume of the long held notes over time using the Velocity XF controller. The Velocity XF fade curve moves through the samples recorded at different volumes. You can also support this Velocity XF controller curve by using CC11 (often used as an expression in the midi world) to create a similar curve. You can also support the sound with the “Timbre Adjust” control (CC 8). For example, CC 8 = 127 for forte tones and CC 8 = 70 for quieter tones (as an example). As Paul mentioned, I would select CC 7 as the basic volume at the beginning of a piece of music and, if possible, leave it at this level for the entire time.
Hardware for “drawing” / recording controller curves...
Unfortunately, everyone has to make their own experiences on this point. Personally, I have tried everything. To this day, I haven't found a controller where I don't have to make improvements afterwards using the mouse. This is also due to the fact that sound changes are not always linear. Turning a control exponentially live is not easy. So that's why I usually still draw curves directly with the mouse. Cubase is very supportive. I don't know how Logic does it. Nevertheless, you have to try it out for yourself. With the Nano controller, you get an inexpensive controller with which you are sure to have good experiences.
In this video you can see most of the things (2. Midi Matters) I mentioned above applied in practice...
Have fun making music with samples
