Synchronizing Multiple Devices

Layla24, Gina24, Mia, and MiaMIDI are designed to work alongside other audio

equipment. If you are planning on using your card with other audio equipment,

please note the following:

The Windows drivers included in this package support multiple Echo cards within

the same system. In addition, your new Echo hardware will operate alongside other

Echo products. Echo hardware can also peacefully coexist with audio equipment

from other manufacturers, but be aware that operating alongside another product is

not the same as operating with it. In order for accurate synchronization to occur,

the other audio product(s) in your system must support a synchronization mode

that is compatible with your particular Echo hardware. Without such

synchronization, the individual pieces of equipment will act independently of each

other. This scenario may be fine for some musical applications; however, it is not

appropriate for situations where sample-accurate synchronization is required or

that will be affected by clock drift.

Let’s take a brief look at the various synchronization types.

Word Clock – This is a synchronization signal that connects to the BNC

connector labeled Word Clock on Layla24’s back panel. This synchronization

clock runs at the selected sample rate. Think of it as a kind of electronic

metronome, which clicks back and forth at the digital sample rate. It is one of the

most widely used forms of synchronization in digital audio. Layla24 is always

generating Word Clock on its Word Clock output BNC connector. Although it can

generate Word Clock at any sample rate it is set to, Layla24 can only sync to Word

Clock if the master device is set to a sample rate between 30kHz and 100kHz.

Otherwise you will get noise and/or loss of sync.
