As shown in the question, if you need to control the technique perfectly, you have to edit the corresponding keys on the key switch to achieve the control of the portamento speed, and there is just one in studio one that can be better triggered by the keyswich key. The function is called tone switching. But it does make it easier to use the key switch. But if you need to edit the intensity of the corresponding key to achieve different skills, it is very difficult in the tone switching function of Studio One. Because it does not support the velocity editing of the key position. So I hope to add the corresponding key velocity editing function. Thank you!
