Hi,
I guess your setup would be like this,
SSID-1 - Lighting system; Port 1 - Lighting console
SSID-2 - Sound system; Port-2 - Sound console.
If that is the case, you can keep the Light system on VLAN-1 and Sound system on VLAN-2. Port-1 on VLAN-1, Port-2 on VLAN-2.
On Lighting system role, block access to VLAN-2.
On Sound system role, block access to VLAN-1.
If one of the Consoles is the DHCP server, allow DHCP on position 1 ACL.
Thanks,
