Sound.Sc3.Ugen.Event

Continous controller event and Ctl systems for external control interfaces.

Cc Event

type CcEvent t = (Int, t, t, t, t, t, t, t, t, t, t)

(v, w, x, y, z, o, rx, ry, p, px, _)

v = voice, w = gate, z = force/pressure, o = orientation/angle, r = radius, p = pitch

cc_event_from_list :: Num t => Int -> [t] -> CcEvent t

Translate list to Event.

type CcEventMeta t = (t, t, t)

(ccEventAddr, ccEventIncr, ccEventZero)

ccEventAddr = k0 = index of control bus zero for event system, ccEventIncr = stp = voice index increment, ccEventZero = c0 = offset for event voices at current server

ccEventMetaDefault :: Num n => CcEventMeta n

ccEventMetaControls :: CcEventMeta Int -> CcEventMeta Ugen

ccEventAddr :: (Ugen, Ugen, Ugen) -> Int -> CcEvent Ugen

c = event number (zero indexed)

ccEventVoicerAddr :: CcEventMeta Ugen -> Int -> (CcEvent Ugen -> Ugen) -> Ugen

c0 = index of voice (channel) zero for event set, n = number of voices (channels)

ccEventVoicer :: Int -> (CcEvent Ugen -> Ugen) -> Ugen

eventVoicerAddr with default (addr, inct, zero).

voicer :: Int -> (CcEvent Ugen -> Ugen) -> Ugen

Synonym for ccEventVoicer.

ccEventVoicerParam :: Int -> (CcEvent Ugen -> Ugen) -> Ugen

eventVoicerAddr with control inputs for eventAddr, eventIncr and eventZero.

ccEventGateReset :: Ugen -> Ugen -> (Ugen, Ugen)

Given g and p fields of an CcEvent derive a gateReset from g and a trigger derived from monitoring g and p for changed values.

Ctl

type Ctl8 = (Ugen, Ugen, Ugen, Ugen, Ugen, Ugen, Ugen, Ugen)

Sequence of 8 continous controller inputs in range (0-1).

ctl8At :: Int -> Ctl8

k0 = index of control bus zero

ctl8Voicer :: Int -> (Int -> Ctl8 -> Ugen) -> Ugen

ctlVoicerAddr with control inputs for CtlAddr and CtlZero.

type Ctl16 = (Ctl8, Ctl8)

Sequence of 16 continous controller inputs arranged as two Ctl8 sequences.

ctl16Voicer :: Int -> (Int -> Ctl16 -> Ugen) -> Ugen

ctl16VoicerAddr with control inputs for CtlAddr and CtlZero.

Names

control_spec_to_control :: ControlSpec Double -> Control

sc3_control_spec :: Fractional t => [ControlSpec t]

See SCClassLibraryCommonControl/Spec:ControlSpec.initClass

"ControlSpec defines the range and curve of a control"

This list adds default values.

kyma_event_value_ranges :: Fractional t => [ControlSpec t]

See Kyma X Revealed, p.403

"The following EventValue names are associated with initial ranges other than (0,1). EventValue names are not case-sensitive."

This list adds curve specifiers as strings and default values.
