Old thread, I know.

I stumbled upon this because ~ does not work for me either running version 0.50.0 on Windows 7, Swedish keyboard.

One workaround is to make a ~ in eg. Notepad and then use cut-and-paste (Ctrl-C + Ctrl-V) into the object

@whale-av Thanks the help.
I am a noob at pd, but learning quickly. It is a fascinating tool,

I am modeling sound from ships and similar vessels mixed with environmental noise. Output is hydrophone signals from an array of hydrophones. It works like a charm for 10 hydrophones at std audio rate without excessive CPU load, so I figure I can increase this number quite a bit without dropouts.

I'll keep you informed but it will take a while, this is a spare-time project.

Thanks a lot for the information whale-av!
64 channels is not bad at all. Good enough for demonstration purposes.

If I wnta more channels it might also be the possibile to dac them all and capture from ALSA with a DAW.

Is there a limit for the number of channels in writesf?
(I would like to write say 96 up to 256 channels.)
