< construction resets table

Member Function Documentation

calcNextIndex()

uint32_t SynthLab::Lane::calcNextIndex ( uint32_t  baseIndex )

inlineprotected

< find next step, wrap if needed (should not need to, but this is backup)

calcPreviousIndex()

uint32_t SynthLab::Lane::calcPreviousIndex ( uint32_t  baseIndex )

inlineprotected

< find next step, wrap if needed (should not need to, but this is backup)

getJumpTableValue()

int32_t SynthLab::Lane::getJumpTableValue ( uint32_t  index )

inline

Parameters

index

get a jump table value (0 to 7)

getNextStepIndex()

uint32_t SynthLab::Lane::getNextStepIndex ( uint32_t &  jumpTableIndex, bool  forwardBackward, bool &  hitLoopPoint  )

inline

Find index of next step.

• always need to know the next steap
• checks forward/reverse operation
• supports bi-directionality
• returns true in hitLoopPoint if the next step is an endpoint (start or end)

Parameters

jumpTableIndex	the current index, the next index is calculated
forwardBackward	true if forward/backward mode enabled
hitLoopPoint	true if advancing to next step hits a loop point

loadNextStep()

bool SynthLab::Lane::loadNextStep ( uint32_t  loopDirectionIndex, bool  applyProbability = false  )

inline

Load next step;.

• update probabilities for next step
• detect loop endpoints and re-shuffle if needed

updateLEDMeterWithCurrentStep()

void SynthLab::Lane::updateLEDMeterWithCurrentStep ( )

inline

Update the LED meter index with current stap index.

• update the LED on-duration with current step duration

updateLEDMeterWithNextStep()

void SynthLab::Lane::updateLEDMeterWithNextStep ( )

inline

Update the LED meter index with next stap index.

• update the LED on-duration with next step duration
