Detailed Description

template<int MaxSlots = 32, typename SampleType = float>
struct pulp::signal::ModMatrixT< MaxSlots, SampleType >

Template Parameters

MaxSlots

routing capacity. Fixed so the matrix stays POD.

active_count()

template<int MaxSlots = 32, typename SampleType = float>

int pulp::signal::ModMatrixT< MaxSlots, SampleType >::active_count ( ) const

inline

Number of slots currently carrying a routing.

clear()

template<int MaxSlots = 32, typename SampleType = float>

void pulp::signal::ModMatrixT< MaxSlots, SampleType >::clear ( )

inline

clear_slot()

template<int MaxSlots = 32, typename SampleType = float>

void pulp::signal::ModMatrixT< MaxSlots, SampleType >::clear_slot ( int index )

inline

evaluate()

template<int MaxSlots = 32, typename SampleType = float>

void pulp::signal::ModMatrixT< MaxSlots, SampleType >::evaluate ( std::span< const SampleType > sources, std::span< SampleType > dests ) const

inline

Accumulate every active routing into dests.

dests[d] += sources[s] * depth * (via < 0 ? 1 : sources[via]).

The caller owns dests: zero it (or seed it with the unmodulated base values) before calling, and clamp it in destination units afterwards.

A stale routing left over from a larger source or destination list can never read out of bounds, but the two cases differ deliberately. An out-of-range source or dest skips the slot — the routing has nowhere to come from or go to. An out-of-range via instead leaves the depth unmodulated, because via scales a routing rather than defining it, and silently dropping the whole routing is the worse failure of the two.

set_slot()

template<int MaxSlots = 32, typename SampleType = float>

bool pulp::signal::ModMatrixT< MaxSlots, SampleType >::set_slot ( int index, int source, int dest, SampleType depth, int via = -1 )

inline

Returns

false if index is out of range; the matrix is unchanged.
