Detailed Description

template<typename SampleType = float>
class pulp::signal::TrigDelayT< SampleType >

Delay a trigger by a fixed time, through a small fixed-capacity queue.

Capacity is kCapacity in-flight triggers. A trigger arriving with the queue full is dropped and counted rather than silently overwriting one — dropping is the honest behavior for a bounded queue, and the counter is there so a caller can notice.

RT contract: a fixed-size array of counters. process() costs kCapacity integer operations per sample and allocates nothing.

USE: flams — run the dry trigger and a 15 ms delayed copy into two voices. Echo-triggering a second layer. Nudging one element of a drum pattern off the grid without touching the sequencer.

delay_ms()

template<typename SampleType = float>

double pulp::signal::TrigDelayT< SampleType >::delay_ms ( ) const

inline

dropped()

template<typename SampleType = float>

long long pulp::signal::TrigDelayT< SampleType >::dropped ( ) const

inline

Triggers discarded because the queue was full since the last reset().

prepare()

template<typename SampleType = float>

void pulp::signal::TrigDelayT< SampleType >::prepare ( double sample_rate )

inline

process() [1/2]

template<typename SampleType = float>

bool pulp::signal::TrigDelayT< SampleType >::process ( bool trigger )

inline

Returns

true on samples where at least one delayed trigger fires.

process() [2/2]

template<typename SampleType = float>

bool pulp::signal::TrigDelayT< SampleType >::process ( SampleType trigger )

inline

reset()

template<typename SampleType = float>

void pulp::signal::TrigDelayT< SampleType >::reset ( )

inline

set_delay_ms()

template<typename SampleType = float>

void pulp::signal::TrigDelayT< SampleType >::set_delay_ms ( double ms )

inline

set_delay_samples()

template<typename SampleType = float>

void pulp::signal::TrigDelayT< SampleType >::set_delay_samples ( double samples )

inline

Direct sample delay, for synced use.

Call it after prepare() — see GateGenT::set_length_samples() for why.
