Generic padsynth oscillators

padsynthOsc :: PadsynthSpec -> Sig -> SE Sig

Padsynth oscillator.

padsynthOsc spec frequency

It makes it easy to create padsynth sound waves (see Tab.padsynth). It creates a padsynth table and reads it with poscil at the right speed.

padsynthOsc2 :: PadsynthSpec -> Sig -> SE Sig2

Stereo padsynth oscillatro. It creates two padsynth ftables for left and right channels.

Simple padsynth oscillators

bwOscBy :: [Double] -> Double -> Sig -> SE Sig

Creates padsynth oscillator with given harmonics.

bwOscBy harmonics bandwidth frequency

bwOddOscBy :: [Double] -> Double -> Sig -> SE Sig

Creates padsynth oscillator with given odd harmonics.

bwOddOscBy harmonics bandwidth frequency

bwOscBy2 :: [Double] -> Double -> Sig -> SE Sig2

Stereo version of bwOscBy.

bwOddOscBy2 :: [Double] -> Double -> Sig -> SE Sig2

Stereo version of bwOddOscBy.

bwOsc :: Double -> Sig -> SE Sig

Pure sine wave with padsynth wave table:

bwOsc bandwidth frequency

bwTri :: Double -> Sig -> SE Sig

Triangle wave with padsynth wave table:

bwTri bandwidth frequency

bwSqr :: Double -> Sig -> SE Sig

Square wave with padsynth wave table:

bwSqr bandwidth frequency

bwSaw :: Double -> Sig -> SE Sig

Saw-tooth wave with padsynth wave table:

bwSaw bandwidth frequency

bwOsc2 :: Double -> Sig -> SE Sig2

Stereo version of bwOsc.

bwTri2 :: Double -> Sig -> SE Sig2

Stereo version of bwTri.

bwSqr2 :: Double -> Sig -> SE Sig2

Stereo version of bwSqr.

bwSaw2 :: Double -> Sig -> SE Sig2

Stereo version of bwSaw.

Layered padsynth

padsynthOscMultiCps :: [(Double, PadsynthSpec)] -> D -> SE Sig

It uses several padsynth tables. Each table is responsible for specific interval of frequencies. The list of pairs specifies the threshhold value and padsynth specification. The padsynth table is active for all frequencies that lie below the given threshold.

padsynthOscMultiCps thresholdSpecPairs frequency = ...

padsynthOscMultiCps2 :: [(Double, PadsynthSpec)] -> D -> SE Sig2

Stereo version of padsynthOscMultiCps.

padsynthOscMultiVol :: [(Double, PadsynthSpec)] -> (D, Sig) -> SE Sig

It behaves just like padsynthOscMultiCps but it spreads the padsynth tables among amplitude values. So the last input argument is a pair of amplitude and frequency:

padsynthOscMultiVol thresholdSpecPairs (amplitude, frequency) = ...

padsynthOscMultiVol2 :: [(Double, PadsynthSpec)] -> (D, Sig) -> SE Sig2

Stereo version of padsynthOscMultiVol.

padsynthOscMultiVolCps :: [((Double, Double), PadsynthSpec)] -> (D, D) -> SE Sig

TODO (undefined function)

With this function we can create square zones in the domain of (amplitude, frequency). We can assign a separate padsynth table for each zone. The list of pairs contains a pair of two threshold values (amplitude, frequency) and dedicated padsynth specification.

padsynthOscMultiVolCps thresholdSpecPairs (amplitude, frequency) = ...

padsynthOscMultiVolCps2 :: [((Double, Double), PadsynthSpec)] -> (D, D) -> SE Sig2

TODO (undefined function)

Stereo version of padsynthOscMultiVolCps.

Granular oscillators

morphsynthOscMultiCps :: MorphSpec -> [(Double, PadsynthSpec)] -> D -> SE Sig2

Combines morpheus oscillators with padsynth algorithm. It uses single table for granular synthesis.

quadMorphsynthOscMultiCps :: MorphSpec -> [[(Double, PadsynthSpec)]] -> (Sig, Sig) -> D -> SE Sig2

Combines morpheus oscillators with padsynth algorithm. It uses up to four tables for granular synthesis.
