Managing Resources
The OASYS PCI provides a large amount of DSP processing power. However, as
with all things in the world, that power is finite. Here are some hints to help you to
optimize the system's resources.
In addition, please see the HTML FAQ for extensive information on optimizing
MacOS and Windows for use with audio and MIDI. Follow the links under
"MacOS General Information" and "Windows General Information."
Sample rate affects processing power
The sample rate affects the processing power available to the OASYS PCI. You'll
get about 8% more processing power for synthesizers and/or effects at 44.1kHz
than at 48kHz.
Adjust the Number of Voices
The OASYS PCI uses fixed voice allocation, which means that if you want to play
six-note chords on an electric piano sound, you must tell the system to reserve six
voices for that Program. This is done through the Patch's Number of Voices
parameter, in the Edit Program window.
You should try to set the number of voices just as high as necessary, and no higher.
The fewer voices you reserve for one Patch, the more that will be available for
other Patches, or for Effects.
Use Send and Output Busses to share Effects
Each Mixer Channel can have its own Insert Effects, which allows for very
powerful and flexible sound-shaping. However, if several Channels each use a
number of resource-hungry Effects, this can eat up DSP resources pretty quickly.
If several Channels are using similar Insert Effects, it may make sense for them to
share the effects through a Send Bus or Output Bus instead. This will free up DSP
resources, which can then be used in other ways.
For more information, see "Using Send Busses to conserve DSP resources," on
page 25, and "Sharing Insert Effects between two or more Channels," on page 25.
Record OASYS PCI synths and effects to disk
If you've maxed out OASYS PCI's DSP processing power, and still want to add
more OASYS PCI synths and effects, here's an easy solution: record the existing
OASYS PCI tracks into your digital audio program, clear off the DSPs, and start
over again.
