dx

float Controller::dx

dx is the increment to x when updateportamento is called

fpar

unsigned char Controller::fpar

freqrap

float 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.

Pchout

unsigned char Controller::Pchout

pitchthresh

unsigned char Controller::pitchthresh

pitchthresh is the threshold of enabling protamento

pitchthreshtype

unsigned char Controller::pitchthreshtype

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

[struct]

struct { ... } Controller::pitchwheel

[struct] [1/2]

portamento [2/2]

unsigned char Controller::portamento

propDepth

unsigned char Controller::propDepth

Depth of proportinal portamento

proportional

unsigned char Controller::proportional

If the portamento is proportinal to the distance spanned

0 - constant time(default) 1 - proportional

propRate

unsigned char Controller::propRate

Rate of proportinal portamento

receive

unsigned char Controller::receive

sustain [2/2]

int Controller::sustain

time

unsigned char 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 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
