Most important: Should I install this? If not, which version should I use?
--------------------------------------------------------------------------
A: prelude.library 5.4, PreludeAHI 6.35 and all the other packages from
http://www.toms-home.de/prelude-dl_e.shtml
This is the oldest but also most stable and heavily tested drivers and
software you can get for your Prelude soundcard. If you're currently
running this and are satisfied then don't change a running system!
One drawback: The AHI driver requires AHI v6 and doesn't work
with AHI v4.
B: prelude.library 5.6, PreludeAHI 6.37 and all the other packages on
AmiNet
These are advanced and anhanced versions by Oliver Gantert, mainly
for his PreludeZII+ project but also backwards compatible with the
original PreludeZII and Prelude1200 soundcards.
All these drivers work with AHI v4 and support connecting the
Prelude1200 to a clock port expander which assigns a different address
to the card.
So if you need one of these features it's worth giving this set of
drivers a try.
C: Prelude Software Bundle V4 (this archive)
This is a fork of the last release by me before Oliver Gantert
took over to improve and refactor it and to include support
for his new Prelude ZII+ soundcard.
I've tried to fix all the bugs which Oliver also fixed in his branch.
Along the way I took the opportunity to implement a watchdog which can
resume a broken and stalled data transfer on its own. This can happen
during some ZZ9000 graphics operations for example. The watchdog can't
prevent the sound from being interrupted for a short time but after
that it will resume automatically instead of just hang.
I've set the version number back to 4 to reflect the AHI v4 support
and to clearly separate it from Olivers branch.
So if you experience unexpected hangups during playback, or if you're
just adventurous, this is the version to try. :)
If you're using an Amiblaster Deluxe soundcard, this version is also
the one to choose.
Installation
------------
Automatic:
- If you want to take full advantage, make sure that at least AHI 4.180
is installed.
- Use the provided installer script which performs all actions.
ATTENTION! The installer script doesn't create a backup of your existing files!
Manual:
- If you want to take full advantage make sure that at least AHI 4.180
is installed.
- Copy Libs/prelude.library to LIBS:
- Copy Devs/AHI/prelude.audio to DEVS:AHI
- Copy Devs/AudioModes/PRELUDE to DEVS:AudioModes
- Copy Tools/Commodities/Mixer to SYS:Tools/Commodities or to SYS:WBStartup
- If you have installed the MPEGit add-on:
Copy Libs/MHI/mhimpegit.library to LIBS:MHI
- If you are using the Amiblaster Deluxe soundcard:
Copy Libs/MHI/mhiamiblaster.library to LIBS:MHI
Common:
- Launch SYS:Prefs/AHI and make the following adjustments:
* Choose "Music unit".
- Select "Prelude: 16 bit stereo++".
- Change Frequency to 44100 Hz.
- Set Volume to +0.0dB.
* Choose "Unit 0".
- Select "Prelude: 16 bit stereo++".
- Change Frequency to 44100 Hz.
- Set Channels to 2.
- Set Volume to +0.0dB.
- Click "Save".
Notes
-----
The saved mixer settings won't be applied before something opens the library.
This can be the mixer itself or any other application like AmigaAMP via AHI or
Prelude Tapedeck.
If you need the settings to be applied early (for loop through for example)
you can launch the mixer once from S:User-Startup with argument "SETONLY=yes",
like this:
SYS:Tools/Commodities/Mixer SETONLY=yes >NIL:
In this case the mixer will just apply the settings and then terminate itself.
Advanced options
----------------
- If you don't want to use the mixer but let AHI control the output volume:
SetEnv SAVE Prelude/AHIAllowVolumeChange 1
- If you have a Prelude1200 installed on a clock port expander:
SetEnv SAVE Prelude/ClockPort 0
..or..
SetEnv SAVE Prelude/ClockPort 1
..or..
SetEnv SAVE Prelude/ClockPort 2
..or..
SetEnv SAVE Prelude/ClockPort 3
.. depending on the expander slot you're using.
- If the MPEGit module is fitted with an oscillator other than 14.31818:
SetEnv SAVE Prelude/MPEGitClock [frequency in 14.31...14.73 MHz]
Example: SetEnv SAVE Prelude/MPEGitClock 14.725

Requirements
------------
A Prelude (or compatible) soundcard, of course :-)
This bundle supports the Prelude Z2, Prelude 1200 and Amiblaster Deluxe.
