Instrument Setting
Multi Touch : For iPhone 5 is maximum touch number, and for iPad it's 10.
Scale Selection :
7 is for major scale[Do Re Mi Fa So Ra Ti Do].
12 for chromatic scale.
5 for pantatonic scale[Ra Do Re Mi So Ra].
5rk is for Ryukyu pentatonic scale[Do Mi Fa So Ti Do].
Subharmonics and Harmonics : adds overtones to currently playing sound. If 3 is selected for harmonics and a playing pitch is 120Hz, it adds 240Hz, 360Hz and 480Hz to the original sound. In same case with subharmonics, it adds 60Hz, 40Hz and 30Hz. Weight : A weight to each harmonics is calculated with the folowing formula.
1.0 / (harmonic index+2)^value
If playing pitch is 120Hz, it would be as folowing chart.

Edit Wave
You can pick up the number of edit points when you create a new tube, but after that You can not change the number.

Edit Wave Interpolation
QUADRATIC BEZIER : Bezier curve with 2 control point.
CUBIC BEZIER : Bezier curve with 4 control point.
QUADRATIC SPRINE : Regular quadratic spline. The curve at first and last edit point might not be smooth.
QUADRATIC MERGE : Calculate quadratic function for each edit point with its before and after edit points, then leanerly add up all values. The curve at first and last edit point is smooth.
LAGRANGE :Interpolate with an ((Number Edit point)-1)th-degree equation. The curve at first and last edit point might not be smooth.
LINEAR : Simple linear interpolation.
STEP : Nearest-neighbor interpolation (also known as proximal interpolation).
NOISE1 : LINEAR interpolation x random[0.0, 1.0]
NOISE2 : QUADRATIC MERGE interpolation + (0.2xrandom[-1.0, 1.0])

Edit Sequence Duration
Fix Minimum Unit Duration : Fix unit duration. Minimum value is 0.01. Default value is 0.05.
Fix Total Duration(Time) : Fix total duration of tube with time input.
Fix Total Duration(beat and tempo) : Fix total dutarion of tube with number of beats and tempo. If tempo is 120 and duration of tube is 8 beats long, the duration will be 60/120 * 8 = 4 seconds.
