It won't work because k-rate variables are undefined at i-time. You can try this

ideltime chnget  "delaytimeL"

which will run the i-time chnget opcode to get the channel value at i-time.

The delay line has a fixed length, that can't be changed at perf-time.

You can use a deltapi etc opcode to tap the delayline.

Maybe you should study some texts Csound programming, which will cover these things. Take a look

at the http://flossmanuals.net/csound/

Hi Victor, 

Thanks. I've tried that. 

The issue is that the delay instrument is being run all the time. ie. i101 0 360000 in the score. 

So putting ideltime chnget "delaytimeL" in the instrument 101 code will only allow me to get the value once on the start of 101, right?
