noteOff() does not work

[jazz-soft]

Tried it with T("PluckGen"), T("OscGen"), T("SynthDef") on several browsers Windows and Mac.
Here is a sample file:

Timbre

PluckGen
OscGen
SynthDef

var env = T("perc", {a:50, r:2500});
var osc = T("pulse");
var synth1 = T("PluckGen", {env:env, mul:0.5}).play();
var synth2 = T("OscGen", {osc:osc, env:env, mul:0.15}).play();
var synth3 = T("SynthDef").play();
synth3.def = function(opts) {
var osc1, osc2, env;
osc = T("saw", {freq:opts.freq, mul:0.25});
env = T("linen", {s:450, r:2500, lv:0.5}, osc);
return env.on("ended", opts.doneAction).bang();

function noteOn1() { synth1.noteOn(60, 100);}
function noteOff1() { synth1.noteOff(60);}

function noteOn2() { synth2.noteOn(60, 100);}
function noteOff2() { synth2.noteOff(60);}

function noteOn3() { synth3.noteOn(60, 100);}
function noteOff3() { synth3.noteOff(60); alert(timbre.version);}

it does not work at https://mohayonao.github.io/timbre.js/PragmaSynth.html either
