## midic21

midic21 — Allows a floating-point 21-bit MIDI signal scaled with a minimum and a maximum range.

## Description

Allows a floating-point 21-bit MIDI signal scaled with a minimum and a maximum range.

## Syntax

    idest midic21 ictlno1, ictlno2, ictlno3, imin, imax [, ifn]

    kdest midic21 ictlno1, ictlno2, ictlno3, kmin, kmax [, ifn]

## Initialization

idest -- output signal

ictln1o -- most-significant byte controller number (0-127)

ictlno2 -- mid-significant byte controller number (0-127)

ictlno3 -- least-significant byte controller number (0-127)

imin -- user-defined minimum floating-point value of output

imax -- user-defined maximum floating-point value of output

ifn (optional) -- table to be read when indexing is required. Table must be normalized. Output is scaled according to the imin and imax values.

## Performance

kdest -- output signal

kmin -- user-defined minimum floating-point value of output

kmax -- user-defined maximum floating-point value of output

midic21 (i- and k-rate 21 bit MIDI control) allows a floating-point 21-bit MIDI signal scaled with a minimum and a maximum range. Minimum and maximum values can be varied at k-rate. It can use optional interpolated table indexing. It requires three MIDI controllers as input.

| Note
Please note that the midic family of opcodes are designed for MIDI triggered events, and don't require a channel number since they will respond to the same channel as the one that triggered the instrument (see massign). However they will crash if called from a score driven event.

Thanks goes to Rasmus Ekman for pointing out the correct controller number range.
