The Ekdahl FAR - Command language: Difference between revisions

Line 33:

* notecount - Contains the number of ''MIDI'' keys that are being held down, i.e. all ''Note on messages'' received that haven't gotten a paired ''Note off message'' yet

* uv0 - uv9 - These are ''user variables'' and can be set at any point using the ''globaluservariable command'' with the first ''parameter'' being which variable to set (0-9) and the second ''parameter'' being the value (float).

''Event variables'' are variables that are set by certain ''MIDI messages'' or when a new value is read on one of the jacks or knobs on the ''Control box''. The ''Event variables'' that are incorporated in the ''firmware'' as of this writing (2025-01-21) are:

Line 44:

* pitch - Set by the ''Pitch bend MIDI message''

* program - Set by the ''Program change MIDI message''

===== Functions =====

''Functions'' can be used to change a numerical value or the result of an ''equation'', the Ekdahl FAR contains both general ''arithmetic functions'' (courtesy of Lewis Van Winkle and the TINYEXPR engine) and ''specialized functions''.

The ''arithmetic functions'' that are incorporated in the ''firmware'' as of this writing (2025-01-21) are:

* abs(x) - Returns the ''[[wikipedia:Absolute_value|absolute value]]'' of ''x''

* acos(x), asin(x), atan(x), atan2(x, y) - Returns the [[wikipedia:Inverse_trigonometric_functions|''arc-cos, -sin, -tan'' and ''-tan2'']] of ''x''

* atan2(x,y) - Returns the ''[[wikipedia:Atan2|arctan2]]'' of ''x, y''

* floor(x), ceil(x) - Returns the [[wikipedia:Floor_and_ceiling_functions|''floor'' and ''ceiling'']] of ''x''

* e, exp(x), fac(x), ln(x), log10(x), log20(x), ncr(x,y), npr(x,y), pi, pow(x,y), sqrt(x)

* cos(x), sin(x), tan(x)

* cosh(x), sinh(x), tanh(x)
