Music Theory, tuning systems, and sound design

Feature:
#1 make a keyboard or midi feature so you can test a sound

#2 you have a volume and balance slider could you make a pitch slider

#3 Wavelet transform, like Fourier transform but more balanced

#4 Rotate sound up and down instead of left or right or have a sound sample view, blender has 3 modes for different uses blender game for physics, default for molding, and render for animation, what if audacity had 2 or 3 modes that change many settings to make a specific task easier like default(current version), wave(change tracks to spectral view move menus around making pitch sifting and other wave edits easier), and music(make sound effect’s more accessible maybe more features that don’t fit in the default view)

Problem to solve: I am using version 3.3.3 interested in learning about tuning and music production I just used Audacity to try and make a sound from scratch I made a 100hz wave and copied it changing pitch which was easy and changing actual track volume which was a little non intuitive but I could do it with adjustable fading but I had to copy a number 3 times for every harmonic, When I finished I was able to change the relative volumes and make a guitar, synth, and piano sound, then after exporting I was able to copy that new sound 12 time’s and make a simple keyboard in audacity but it was clunky and hard to use and I could only play one chord at a time
