Hi,
I'm looking at creating an envelope by feeding [vline~] into an array. I have a message box containing the numbers for the envelope's attack and release target amplitudes and slope times. From what I can see in the [vline~] help file the first character in the message determines the target amplitude and the second determines the time it takes to reach the given amplitude. And if there is a third it gives a time delay.

I seem to have it working correctly with the following message: -

[1 100, 0 100 100<

the visual line in the array represents these transients and timings perfectly.
but when I change the second parameter in the message from 100 to 200... like this: -

[1 200, 0 100 100<

it actually reduces the amplitude instead of making any changes the timing.
Can anyone please see what I'm doing wrong? I assumed that by changing the second parameter the peak would move to the right slightly.... not downwards.
Here's a couple of screenshots
Thanks

@liamorourke Pretty sure it has to be [1 200, 0 100 200(...... as initial delay needs to be consistent in a scheduled message.
The second part of your message is interrupting the first part.

ahhh... that would make sense. I'll try it out when I get home shortly and report back thanks

okay... that works. thanks. however I'm now confused because in this video the guy changes the slope time to 10 milliseconds whilst leaving the delay at 100 milliseconds. and it works fine for him.

he does this at about 50 seconds into the video. any idea why this is?

thanks again

@liamorourke Because 100 is more than ten....... so it goes up in 10ms and then waits..... stays at 1 until 100ms and then ramps down.
Each message part, after a comma, has as its last of 3 values the time at which it will start..... the trigger time......
Apart from the first of course which triggers immediately.
When he then changes the final value to 10 as well the ramp down starts at the end of the ramp up again.
The message is distributed across the 3 inlets of [vline~]
1 value to go to
2 time to do it.... [vline~] ramp time
3 time at which to start doing it..... the time at which to start the ramp

You can put comma separated lists of the 3 values one after the other...... as many as you want...... and they will all be scheduled to start at their trigger time in ms from when the message was received.

Actually the first message can be scheduled as well...... but that's not usually useful.
David.

okay right... so the delay time is actually a trigger time measured from the start of the array? this makes sense.

for some reason i assumed it was from the start of current transient/ end of the last.... which when i think about now... doesn't really make any sense.

I'll give out a go and report back again. thank you so much for your help.

@liamorourke Yes. It isn't obvious. Not really from the start of the array, although that is the effect when you send it into an array to visualise it...... but from when the message is received.
David.

just had another little look and I completely get it now. thank you so much
