Can you recommend a procedure to address individual samples of a wave-file you read into the SndBuf. </div>

<div>Hi Herman,</div>
<div><br>
</div>
<div>In ChucK you can also go sub-sample rate (ie 0.5::sample => now;). <br>
</div>
<div>I wouldn't worry about the <i>rate</i> of the events (how fast they're generated), I think it's slightly more complex than that.
<br>
</div>
<div>I would assume (and I'd like to ask someone on the list more expert than me to validate this statement) that as long as the event can be
<i>captured</i> <i>at</i> <i>low level </i>by<i> </i>ChucK, then you can use it to trigger
<i>now</i>.</div>
<div>In the case of USB MIDI then, there are also some aspects of the implementation of the various MIDI libraries that help in scenarios where too many msg are sent.</div>
<div>For example, the computer and/or the hardware connected to it, can communicate the fact that they're busy and thus whichever of the 2 is the one that sends the msg, can wait before sending the next one (all this assuming that both implemented USB MIDI
the same way).</div>
<div>Now, as far as I know this mechanism is not always in place (both in USB MIDI libraries and hardware/software products), and I honestly don't know whether or not ChucK uses it (I suppose it would be the case of having a look at the source code - RtMidi
and the way ChucK interfaces to it).</div>
<div><br>
</div>
<div>About<i> now</i>, this can work with <i>dur</i> and<i> time</i> data types and
<i>events</i> (Event, MIDI, HID).</div>
<div>About the MIDI use case, your <i>MidiIn</i> objects receives a MIDI msg (so ChucK is aware of the msg already) and then triggers
<i>now</i>.<br>
</div>
<div>At that point your script/program proceeds and go to the next instruction (ie whatever else in the code comes next).</div>
<div><br>
</div>
<div>Cheers,</div>

So once you started the VM to run, time floats at the speed of 44100 times a sec. So the "now" can only see things if they'r fed into it at a frequency less or even a 44100 th time of a second. </div>

Does this mean that i can feed anything into the "now"? Or only things that contain a kind of trigger? But in case of a midi message this trigger "min => now" kind of wakes up chuck to do the nex thing on the list? e.g. read the incoming message?</div>

<div>to be a bit more precise, when you have something like</div>

<div>your program waits for a MIDI event in order to advance, but the ChucK time is still running.</div>

<div>Hi Herman,</div>
<div><br>
</div>
<div>You can use Events/MIDI/HID to advance in time.</div>
<div>Have a look at this chapter if you want to know more about it <a href="https://en.flossmanuals.net/chuck/_full/#events" target="_blank">
https://en.flossmanuals.net/chuck/_full/#events</a></div>
<div>In a nutshell what happens is that a MIDI event is received and that turns into a
<i>trigger</i>, so your program advances in time. Otherwise it stays there until a MIDI even happens.</div>
<div>See it more as a trigger than a <i>time constant</i> if that makes sense.<br>

Normaly you can only feed time or duration into now ( e.g. 10::ms => now)</div>
