Introduction

This package contains an AmigaOS helper utility that generates

a Kickstart module to initialize the mixer settings for the

Macrosystem Toccata sound card while Kickstart boots. This way,

Amiga audio passthrough is available early, before HDD based

booting takes place.

Usage

First, use ToccataControl (from the Toccata install disk) to

set up the desired mixer settings (typically, by moving the

AUX2 slider up).

After the settings of ToccataControl are saved, invoke

toccatainitgen

from CLI. By default, it will write the result as

"toccatainit.module".

That module can be used/tested with "LoadModule". Typically,

a user might want to install the module permanently. A number

of expansions offer the ability to flash such modules (e.g.

Deneb, FreeWay Pro, BFG9060, ...). Custom Kickstarts might also

be an option.

Options

VERBOSE/S - detailed output of parameters as parsed from

ENV:Toccata.regs

FILE=OUT/K - output file path, e.g. toccatainitgen FILE=ram:tmod

Notes

A pre-built module for AUX2 is available in the Examples

subdirectory that can be used directly in case that those

settings appear satisfactory.

Technical Notes

The Toccata sound card requires a delay after a chip

reset. In order to avoid additional boot delays, the

Kickstart module is separated into two phases. First,

the reset is issued, after which other modules can

initialize. A second later, the actual setup of the

registers takes place within a task that shuts itself

down when done.
