/*
 * this mapping is used for the edirol pcr-800
 * this should be changed when using another controller
 *
 * Make your own mapping:
 * The MIDI controller might send different control change messages when moving knobs,
 * sliders and pressing buttons (if available)
 *
 * Usually the controller sends message on a selected channel (configured channel).
 * The channel is represented by the first hex value.
 * In the mapping for the PCR-800 the first hex value is different because the controller is configured a bit weird.
 * MIDI channel 1 to 16 are represented by the values 0x0 to 0xF
 *
 * The second value represents the control change number.
 * Some are defined by the MIDI specification like 0x40 - "sustain"
 *
 * The third value is a free text. This might be used in future for display purposes.
 * You can just enter some text to identify the knob etc.
 *
 * The last three values are for linking a function + user parameter
 *
 * For example your controller is sending a control change message
 * - channel 0x2, control number: 0x11, value: 0x32
 * following entry will be identified as linked:
 * { 0x2, 0x11, "S3", NULL, Synth_SetParam, SYNTH_PARAM_VEL_ENV_SUSTAIN},
 *
 * The function Synth_SetParam will be called with following parameters:
 * Synth_SetParam(SYNTH_PARAM_VEL_ENV_SUSTAIN, 0x32);
 *
 * Some functions ignore the additional parameter in that case the last value can be left as zero.
