can you explain loud ?

Sorry for my bad english. I meant loud in the sense of to complicated, difficult. Because it is so simple with a midi cable. You wire it, and press play. and everything is ok.

so why not use netjack ?
grab current jack release and go.

I understood that the slave computer using netjack backend can't use audio, or through alsa_out and alsa_in.
I own a firewire sound card, so I think this is not possible for me... is it ?

it now works over wireless. use celt codec to
reduce bitrate. should give you 4channels in both directions easiely.
and i guess you only want 8 channels in one direction.

Does it offers good performances ? latencies speaking ?

I can't really imagine how it works. and how to implement this solution.

netjack.
its even sample accurate.

By the way, Seq24 developpement is bakc, and I saw that midi slave feature is planned. So ... I just have to be patient.
