353 Question: How many MIDI channels does it support?
Answer: 48 (32 Internal and 16 external).
354 Question: When I plugged a synth into the external port of my AWE32 with the DB50XG
fitted, the same sounds that were played by the DB50XG were played by my synth. Will this
happen on the SW1000XG?
Answer: No, the ports are independent.
355 Question: If I wish, can I turn off XG channels on the card?
Answer: Yes, using sysex, but why would you want to?
356 Question: In Cakewalk , is it a good idea to run the audio profiler before I use the
SW1000XG?
Answer: Yes, just the first time you go to set up Cakewalk with the SW1000XG.
357 Question: The PLG100Vl board uses physical modeling synthesis. Where can I find out the
really serious info I need to get into the deeper side of this technology.
Answer: The internet is a great place to start, as hundreds of sites (educational and research)
cover this topic in depth. There are also editors for the PLG100VL free on the Yamaha site in
the VL70 and Sondius ‘goodies to download’sections.’
358 Question: Does the SW1000XG or the DSP Factory use any form of audio compression
(such as used by mini disc and some other hardware based Hard Disk Recording systems?)
Answer: No, it is raw and pure audio, with no compression. So what you hear is what you
get.
359 Question: What if the memory location that the SW1000XG is attempting to use is already in
use by another card, for example a legacy device such as the Adaptec 1542CF SCSI card?
Answer: Just go to your System Properties and click on Resources (Control Panel/System/
Device Manager/ Resource Tab), select Manual Configuration and change the setting until you
see ‘ no conflict ‘ on the SW1000XG.
360 Question: My Windows 95 system refuses to let me change the setting of the SW1000XG
resources in the device manager. What do I do?
Answer: Latest revisions (OSR2) of Windows 95 allow what is known as IRQ steering. Please
contact Microsoft for information on how to update your system so that it supports this feature.
Your version of Windows (400.950) will be shown in your system box in control panel. OSR2 (or
2.1) is 400.950b, Service Pack 1 is 400.950a, and original Windows 95 is 400.950.
361 Question: What is IRQ steering then?
Answer: Windows 95 OEM Service Release 2 (OSR2) provides support for PCI bus IRQ
steering. By using PCI bus IRQ steering, Windows can dynamically assign or "steer" PCI bus
IRQs to PCI devices. Note that Microsoft Windows 95 (retail release) and Microsoft Windows 95
OEM Service Release 1 (OSR1) do not provide support for PCI bus IRQ steering.
ISA and PCI IRQ's
Multiple Industry Standard Architecture (ISA) devices cannot share an ISA IRQ. However, multiple
PCI devices can share a PCI IRQ. On computers that use a PCI bus, the 16 standard IRQ's can
be programmed to either PCI or ISA mode. An IRQ cannot be programmed for both modes at
once.
How IRQs Are Assigned to PCI Devices
In Windows 95 (retail release) and OSR1, the Basic Input/Output System (BIOS) assigns IRQ's to
PCI devices. With OSR2, if PCI bus IRQ steering is disabled in Windows the BIOS assigns IRQ's
to PCI devices, but if PCI bus IRQ steering is enabled, Windows assigns IRQ's to PCI devices.
