grid
Generates a 2d grid, for further lissajous applications.
Inlets
frac32 pitch of the oscillator
int32 number of rows, overrides the parameter
int32 number of columns, overrides the parameter
Outlets
frac32buffer x coordinate
frac32buffer y coordinate
Parameters
bool32.tgl bipolar output if checked (rows and columns spanning from -64 to 64 instead of 0 to 64)
frac32.s.map.pitch pitch of the oscillator
int32 number of rows
int32 number of columns
