add to midi or osc mapping

use |f: : to bookend your formula

eg

"control_change 48": {

|
"NAV_DETOUR": ["set_detour_speed_position_continuous"]
|
|
},
|
|
|
|
example above inverts input, runs sin(x*pi) on it, then uses that value to set the shader param layer 0. it also sets variable A to be the *original* value, and call print_arguments to print it

|
|
|

"control_change 49": {
|

"DEFAULT": ["set_the_shader_param_1_layer_offset_0_continuous&&A>print_arguments","set_shader_speed_layer_0_amount"],
|
|
"NAV_DETOUR": ["set_detour_start_continuous"]
|
|
},
|

|
example above outputs value stored in variable A and prints it

invert input, send to variable and to shader ?
