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>min => now;</div>
<div>your program waits for a MIDI event in order to advance, but the ChucK time is still running.</div>
<div>Anyway, more info in the link I shared :)<br>

<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>
</div>
<div><br>

Normaly you can only feed time or duration into now ( e.g. 10::ms => now)</div>
<div style="font-family:Calibri,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
