| Description: | Expression Mapper is a modulation device that allows the user to specify the modulation behaviour using javascript expressions. It provides 8 control value parameters that can be renamed to make more human readable expressions. It features a built in metronome to force updates at a given interval. By referencing 'time' in your javascript expressions you can also create complex LFO type effects. The results can be mapped to up to 8 other parameters with range remapping. This is my first Max for Live device and hasn't had a great deal of testing yet, but hopefully it's already of use to some. I'd be interested to hear any comments or suggestions for future versions. Version History: 1.0: - Initial Release 1.1: - Fixed so the mapping only updates from metronome ticks when metronome enabled and transport is running. - Added build in convenience functions: saw( periodInBeats, phaseOffset ) - Generates a sawtooth wave locked to Live transport. square( periodInBeats, phaseOffset ) - Generates a square wave locked to Live transport. pulse( periodInBeats, phaseOffset, dutyCycle ) - Generates a pulse wave locked to Live transport. sine( periodInBeats, phaseOffset ) - Generates a sine wave locked to Live transport. triangle( periodInBeats, phaseOffset ) - Generates a triangle wave locked to Live transport. fit( value, oldMin, oldMax, newMin, newMax ) - Transforms clamped value from old range to new range. fit01( value, newMin, newMax ) - Transforms a value with range 0 - 1 to new range. curve( value, slope ) - Remaps value in range 0 - 1 using exponential slope with range -1 to 1. - Added graphical display. 1.1.1: - Fixed UI bug hiding extended mapping display. 1.2: - Rearranged internals. Please note that because of this settings will not migrate from 1.1.1 to this version. - Reworked Metronome feature to stay in sync with Live transport. - Added smoothing control. Please note that this relies on the target device/parameter supporting the live.remote~ smoothing feature, which isn't always the case. Eg. currently Operator doesn't seem to work, but Wavetable does. - Fixed miscellaneous bugs. 1.2.1: - Fixed bugs with multiple expression mappers in a set |
