Drag around rows to switch with other rows [Space] to play notes [B] to repeat a note [Z] to start playing from the beginning [R] to reverse the grid [I] to invert the grid [S] to save your permutation [L] to load in a permutation [T] to load in a tuning - Tunings look like 171.42,342.85,514.28,685.71,857.14,1028.57,1200 (cent values) or 9/8,5/4,4/3,3/2,5/3,15/8,2/1 (just intervals), with no spaces. Mixing ratios and cent values is fine. [A] + [1] to randomize the grid [A] + [2] to randomize the grid (while minimizing consecutive notes) [A] + [3] to pseudo-randomize the grid [C] to load in a switching algorithm - Switching algorithms look like 8/7,1/n3,n4/5,etc. where each switch is separated by ",". A/B will switch the rows A and B. nA is the row where the note in column A is.
