Re: [linux-audio-dev] Two / Three HDSPM Cards?

Hi, thre Madi cards in one PC is a great idea. But the real trick is
getting the CPU to process 192 ins onto 192 outs!

I also saw the typo and I hate hand generating long lists of incremented
values, which is quite error prone. So I wrote a script (attached). I
tried it out with our Madi cards. By experementing I have found that
multi card works with <= 32 channels per card for two cards!! So max of
64 in/outs. where is this from ?! I had increased the max port count to
256 but that didn't help.
