Hi friends, I just bought a layla24 (echo) and it work as perfect!!! the echomixer is a great work!!!! I prepare an installation in NY and I will use it with the ALESIS AI3 to extented to 16 I/O through the ADAT optical I/O... I never do this, I would like to share with you guys experiences on this... And if there is not problem to use jackd after... and to see the I/O... because jackd don't show up the adat optical I/O of the layla24, I mean I have to try but the Alesis wait for me in NY ;-) If you have some experiences with this kind of device, it will be a great help for me!!!! cheers Julien http://www.apodio.org http://www.apo33.org http://www.noiser.org
