el.sparseq2([props], t)
Just like el.sparseq, the sparseq2 node is for sequencing
values over time. The difference is subtle: sparseq2 takes time as an input
signal, whereas sparseq maintains an internal notion of time. Usage is otherwise
nearly identical.
sparseq2 expects a sparsely defined sequence given as an array of { time, value } pairs as the seq prop, and a single input signal giving the current
time value. The specific units of time are at your discretion, but you should be
sure that the values given in the seq prop are in the same units as the input
signal.
Example:
// A sequence that deals in sample time (as given by el.time() in either the
// web-renderer or offline-renderer), and increments from 1 to 4 stepping once
// per second at a 44.1kHz sample rate.
el.sparseq2({seq: [
{ time: 0, value: 1 },
{ time: 44100, value: 2 },
{ time: 44100 * 2, value: 3 },
{ time: 44100 * 3, value: 4 },
]}, el.time());// A sequence that deals in "beat" time (or ppqn), and increments from 1 to 4
// stepping up on each beat.
el.sparseq2({seq: [
{ time: 0, value: 1 },
{ time: 1, value: 2 },
{ time: 2, value: 3 },
{ time: 3, value: 4 },
]}, ppqn);Props
