I feel like I spent a lot of time yesterday practicing for the hamster stand piece, so today I decided that each day I'll start with practicing the twister mat piece first so it doesn't get neglected. I think the tendency to practice the hamster stand piece more is because its mapping is more similar to that of a traditional instrument; it has exact pitches and timbre to worry about and a historical understand of what its sounds should sound like. AKA There would likely be more understanding and criticism from an audience about what would make it sound "good".
I found that instead of trying to memorize which FSR is mapped to which specific note and trying to think about music theory and chords while I am playing (something that I can't do very well with violin either), it is easier to think of how many FSRs are in between the two that I'm playing. One FSR in between are the easiest to visualize and they are thirds. Then I think about two FSRs in between, then three, ect. Thinking this way helps me make more "musical" decisions in the moment than to think about perfect 5ths, 4ths, 6ths, etc.
So today with the twister mat practice I realized that it is difficult to remember exactly what is mapped to what with the accelerometer and the IR sensor; it's different for each colour. I realized that some colours, like green for example, used only the X axis of the accelerometer, and others used only the Y axis. This is more challenging to remember, so I changed it so that whenever there is only one axis mapped, it is the Y axis. I have a preference towards the Y axis because of how the FSRs and IR are oriented.
I also realized that some playing techniques are more preferable than others depending on the sound engine. For example, I don't like how it sounds in the yellow when the ball is upside down. But I love it when the ball is upside down when it is green. I like to roll the ball around on the ground a lot when it is red, but not so much with the other colours.
