Multi Chip Support:
The Project Open Dialog:
If the user checked the multi-chip box in the project open dialog, support for multi-chip projects is
enabled. What this means is that if a project becomes larger than the total duration of the chip it is
associated with, the system will automatically allow for one or more similar chips to be programmed at
recording time to contain the whole project. The maximum number of chips for a multi-chip project
is 4, numbered from 0 to 3.
At recording time, phrases are recorded one after another, and the system pre-computes the space
necessary for the file before it attempts to record it onto the ISD chip. If it is determined that there is not
enough room, the system will pause and ask the user to plug in the next chip. The current chip number
is automatically increased, and will appear in parentheses at the end of the address information in the
project window.
Since there is no way for the system to know which chip (if any) is in the socket; the user is responsible
for placing the correct chip in the socket during playback. Similarly, concatenations using phrases from
different chips cannot be heard correctly. They should be tested in wav format only. When multi-chip
support is enabled, the table creation program will create one table (extension: .tbx, with x=0,1,2,3) for
each chip that is necessary to record the whole project.

This dialog is invoked every time a new or existing project is opened. If the already existed, this is an
opportunity for the user to modify certain parameters.
