After talking to our tutor Leo this week, we made the following things clear:
1. list all controllable variables on Max and select some variables object that can be controlled by sensor.
2. Connect the sensor to Max to see if it can be controlled.
3. The connection between the sound effects and the Max can be used (the Pictslider object adjusts the parameters of the xy axis). I need to build it, and still choose the controllable variable to connect the sensor.

This is a technical problem that was solved last week:
How to control color change
How to control pattern change


This is a defined variable that needs to be controlled by sensors:
The control of color is not in line with the theme and is not technically realized, so it is ruled out.
The visual part can adjust the pattern, including draw mode and size of the waveform changes.
I set the range values of the two:[0,11] and [-120,2]
It has got the sound effect package made by the team members, as shown in the figure below, which are the implementations of the sound effect part I built.
Problems encountered:

The four corners of the pictslider object only support the transmission of four sound effects, and there are many transmission media that need larger volume for sound effects.

The nodes object can hold enough sound effects, but how to control the yellow controller ball is a key problem. If the sensor can be connected with the ball, the audience can control it in real time to feel the trigger of different sound effects caused by their actions.
