June 1, 1998. Tomas Hurka is supporting the Multiwav Pro driver for NeXTStep/OpenStep, and plans to update it to Rhapsody. He has recently updated the driver to support the new Pro 24 cards from AdB. We appreciate his work very much.

November 1996. Thanks to the amazing work done by Tomas Hurka, and with help from Rob Poor at MIT, we have managed to write the first NeXTStep driver for a professional quality digital audio card. This was no mean feat.

The AdB Digital Multiwav is an ISA digital I/O card with AES/EBU, S/PDIF, TosLink input and output, and an additional 18 bit analog output. We now can transfer digitally from DAT to computer, and back. In addition, we can also incorporate outboard digtial effects, such as our new Lexicon MXP1s and PCM90, into our signal chain with no noise degradation. The following is the release note for the Multiwav Driver. You can find it at:

Version 1.14 of Multi!Wav Adapter Device Driver for NEXTSTEP Release 3.2 and 3.3 for Intel Processors and OPENSTEP 4.0 /Mach   The Harvard Computer Music Center, Rob Poor, and Tomas Hurka announce the first NeXTStep for Intel driver for a professional audio card. Thanks to the amazing work of Tomas Hurka, we have completed a driver for the AdB Digital Multiwav Pro and Multiwav Pro-18 cards.   OVERVIEW: Multi!Wav Adapter device driver lets you take advantage of the following adapters: Manufacturer Adapter PC Bus AdB Corp. Multi!Wav Digital PRO ISA AdB Corp. Multi!Wav Digital PRO18 ISA   These Multi!Wav cards provide AES/EBU, SPDIF, and TOSLINK input/output to your NeXTStep Intel machine. The Pro-18 card adds an 18 bit digital to analog converter for monitoring. For more information about AdB sound cards see the AdB www home page at http://www.adbdigital.com.   Driver supports 32000, 44100 and 48000 Hz sampling rates, 16 bit linear sampling in mono or stereo format. The driver makes the card work like a standard audio card, so special software is not needed for digital tranfers, though we recommend Bernhard Scholz's excellent SASound.app for recording. The driver is robust, and provides much better playback that what you might be used to from the Microsoft Sound System, SoundBlaster, or Pro Audio Spectrum.   Harvard Computer Music Center are currently using the cards to do direct to DAT transfers, and with Lexicon MXP1s for digital reverberation without leaving the digital realm. They're proven to be a remarkable improvement over our Microsoft Sound System Cards.   WARRANTY:   THIS SOFTWARE IS PROVIDED BY THE REGENTS AND CONTRIBUTORS ``AS IS'' AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

You can freely distribute without changing or removing any parts of the package. If you found the driver reliable, please, register the driver. For more details see document Registration.rtf. Release 1.13 notes: 1. This a first public release of the driver. 2. Only Multi!Wav Digital PRO with XLINK XC4003A is supported. Other two versions (XC4004A and XC4003E) of XLINK can be supported on request. 3. Driver does not use IRQ since Multi!Wav card cannot generate one. The result is this log message when the driver is loaded by Mach OS: MultiWav at dma channels 6 and 7 irq -268415659 This does no harm, just Sound class does not count with the sound driver without IRQ. INSTALLATION:   These instructions show you how to install the Multi!Wav adapter device driver on an Intel-based computer running NEXTSTEPä. The driver is distributed as a file named MultiWav.1.13.I.b.tar.gz.   1. Install Multi!Wav card under Windows and set all hardware switches using AdB installation program. Test that he card works correctly under Windows. 2. If you received the MultiWav.1.13.I.b.tar.gz file via NeXTmail or downloaded via FTP or another electronic source, place a copy of the file in a location where you can access it when you log in as root. 3. Log in as root. Only the superuser, root, can install the device drivers. If you're not sure how to log in as root, see your system administrator. 4. Uncompress and unarchive the MultiWav.1.13.I.b.tar.gz file. 5. Double-click the MultiWav.config. This automatically launches Configure.app and copies the driver into the /NextLibary/Devices directory. 6. Add the MultiWav driver (PRO or PRO18) as a Sound device, and configure port address according to the card setting. The default setting should be OK for most cases. 7. Save configuration and quit Configure.app. 8. Reboot computer.   BUGS: Send all bug reports and any other suggestion via e-mail to tom@hukatronic.cz. Please, remember to include your configuration.   Special thanks to: Sean Anthony Varah <cello@mario.harvard.edu> R.
