The Kyma Language for Sound Design, Version 4.5

AnalogSequencer
Sequencers Category
Generates sequences of note events and continuous controller values for EventValues in parameters of
the Input. There is a sequence of MIDI notenumbers, durations, duty cycles and velocities to supply MIDI
note events to the Input, and ExtraValues lets you supply a sequence of values for any continuous
controller EventValues in the Input’s parameters.
The length of all sequences is the length of the longest sequence; any shorter sequences will repeat their
final values in order to be as long as the longest sequence. For example, if you want all values in a
sequence to be 0.5, you need only enter the number a single time, because it will be repeated for as
many times as necessary to make it as long as the other sequences.
If Step is a constant 1, then the Durations and the DutyCycles are used to determine when !KeyDown
events should be generated and how long each key should remain down. If no other units of time are
used and if the value of Rate is 1, the numbers in the Durations sequence are interpreted in seconds.
Rate is a divisor on the length of each duration, so if Rate is greater than 1, the durations will be shorter,
and if Rate is less than 1, they will be longer.
Use Step to step through the sequences one by one, according to a trigger. For example, you could use
!KeyDown to control the step rate from a MIDI sequencer, or you could use 1 bpm: (!Speed * 1024) to
control it with an internal metronome, or you could paste in an audio signal that has been passed through
an amplitude follower and a threshold to trigger each element of the sequences in synch with an audio
signal, or you could use !TimingClock to step using the MIDI clock from a software sequencer or external
synthesizer.
To trigger using the Step field, you should set all Durations to the same value; this value (taken along with
the value of DutyCycle and Rate) will determine the duration of each note, and the Step trigger will
specify the onset time of the note. The value you pick for the Durations will act as a kind of "mask" on the
speed of the step triggers. Notes cannot be triggered any more often than the minimum values specified
in the Durations field. This can be helpful if you are triggering from the !TimingClock (24 triggers per
beat) or an audio signal with lots of peaks in it, because it will force the sequencer to ignore triggers that
occur faster than at the desired rate.
Input
EventValues anywhere in this Sound can be controlled by the arrays of key events or continuous
controller values sequenced by this AnalogSequencer.
Left
Attenuator on the left channel amplitude.
Right
Attenuator on the right channel amplitude.
Gate
When this value changes from 0 to 1, it restarts the sequences. If Loop is checked, the sequences will
repeat for as long as Trigger is nonzero.
Use a constant value of 1 to get an infinitely repeating sequence. Use an EventValue such as !KeyDown
to restart and stop the sequence interactively.
