Problem on passing argument lists into jit.gl.lua

October 10, 2013 | 9:53 am

Hi, guys

Max 6 crashes when argument lists (> 83 elements) are passed into "jit.gl.lua" in a short time.

Acturally I would like to pass arguments list, which has 128 elements, into "jit.gl.lua" in each 20 milliseconds.

Does anyone have same problem? How to manage it?

Any help would be appreciated. Thank u :)

I think that jit.gl.lua crashes max6, when i call lua function with large variable arguments on short interval. for example, when I send fft list data to lua.

Is there any solution for this problem?
