Member Data Documentation

[struct]

struct { ... } zyncarla::Controller::bandwidth

bendrange

short int zyncarla::Controller::bendrange

bendrange_down

short int zyncarla::Controller::bendrange_down

data

int zyncarla::Controller::data

<Portamento

depth

unsigned char zyncarla::Controller::depth

dx

float zyncarla::Controller::dx

dx is the increment to x when updateportamento is called

exponential

unsigned char zyncarla::Controller::exponential

[struct]

struct { ... } zyncarla::Controller::expression

[struct]

struct { ... } zyncarla::Controller::filtercutoff

[struct]

struct { ... } zyncarla::Controller::filterq

[struct]

struct { ... } zyncarla::Controller::fmamp

freqrap

float zyncarla::Controller::freqrap

this value is used to compute the actual portamento

This is a multiplyer to change the frequency of the newer frequency to fit the profile of the portamento. This will be linear with respect to x.

is_split

bool zyncarla::Controller::is_split

last_update_timestamp

int64_t zyncarla::Controller::last_update_timestamp

[struct]

struct { ... } zyncarla::Controller::modwheel

noteusing

int zyncarla::Controller::noteusing

this is used by the Part for knowing which note uses the portamento

[struct]

struct { ... } zyncarla::Controller::NRPN

RPN and NPRPN

origfreqrap

float zyncarla::Controller::origfreqrap

this is used for computing oldfreq value from x

struct { ... } zyncarla::Controller::panning

parhi

int zyncarla::Controller::parhi

parlo

int zyncarla::Controller::parlo

pitchthresh

unsigned char zyncarla::Controller::pitchthresh

pitchthresh is the threshold of enabling protamento

pitchthreshtype

unsigned char zyncarla::Controller::pitchthreshtype

enable the portamento only below(0)/above(1) the threshold

static

propDepth

unsigned char zyncarla::Controller::propDepth

Depth of proportinal portamento

proportional

unsigned char zyncarla::Controller::proportional

If the portamento is proportinal to the distance spanned

0 - constant time(default) 1 - proportional

propRate

unsigned char zyncarla::Controller::propRate

Rate of proportinal portamento

time [1/2]

const AbsTime* zyncarla::Controller::time

time [2/2]

unsigned char zyncarla::Controller::time

The time that it takes for the portamento to complete

Translates in an expontal fashion to 0 Seconds to 1.93f Seconds of completion time

updowntimestretch

unsigned char zyncarla::Controller::updowntimestretch

this value represent how the portamento time is reduced 0 - for down portamento 1-63 - the up portamento's time is smaller than the down portamento 64 - the portamento time is always the same 64-126 - the down portamento's time is smaller than the up portamento 127 - for upper portamento 'up portamento' means when the frequency is rising (eg: the portamento is from 200Hz to 300 Hz) 'down portamento' means when the frequency is lowering (eg: the portamento is from 300Hz to 200 Hz)

used

int zyncarla::Controller::used

if a the portamento is used by a note

Todo

see if this can be a bool

valhi

int zyncarla::Controller::valhi

vallo

int zyncarla::Controller::vallo

[struct] [1/2]

struct { ... } zyncarla::Controller::volume

volume [2/2]

x

float zyncarla::Controller::x

x is from 0.0f (start portamento) to 1.0f (finished portamento)
