In this it has been very successful, and most PCI, USB and Firewire audio interfaces on the market now offer their best performance under Core Audio in OS X. I/O, I/O, It's Off To X We GoĬore Audio was designed to be a central part of OS X, a single I/O engine for use by all applications which would operate at as low a level as possible in the OS to reduce the amount of to and fro between applications and hardware drivers, and thus also reduce both processing demands and latency. I decided to investigate how this comes about, and to see what, if anything, can be done to counteract or work around this reduction in the number of inputs and outputs available to the user. Indeed, the main complaint that SOS hears from end-users migrating from OS 9 to OS X is that they were not aware that this reduction of channels would happen until they embarked on the procedure and found themselves with fewer I/O channels available. However, the biggest single reason that I hear for not moving the main studio computer across to OS X is that it would currently cause a reduction in the number of available I/O channels.

Whilst this might seem a rather penny-pinching attitude when applied to individual pieces of software, when you look at the number of plug-ins that people may have acquired on an OS 9 system over the years and how many different update charges it may entail to replicate this exact setup of plug-ins under OS X, it becomes understandable. Many owners cite the lack of availability of a particular plug-in as their reason for not wanting to move over, or sometimes a freeware or shareware program which has not yet been ported across.Ī more commonly cited reason, now that most plug-ins have been ported to Audio Units or VST under OS X, is that the developers (not surprisingly) want to charge something extra to 'upgrade' to the OS X version, whereas the users (also not surprisingly) don't want to pay for something which gives them no additional functionality, just the ability to run under the new OS. In contrast, the majority of the non-portable Macs I see are still running OS 9. After all, if you want a portable system, you're more likely to want to be unencumbered by hardware and use software instruments, and to do this, you'll need a recent, powerful machine, the majority of which now only run OS X. In keeping with this, most Powerbooks I see these days are running OS X for music and audio. This is particularly the case amongst musicians who haven't yet got into using CPU-hungry software synths and samplers, and are still predominantly running external hardware MIDI instruments with older, slower Macs.

Why is this? Well, there are some people who simply don't feel the need to upgrade yet, as their OS 9-based music system is meeting all their requirements. And there are quite a few people out there whose music Macs remain stubbornly on OS 9, even if they have other computers that have migrated to OS X.

Most Mac users I know are now running Mac OS X in day-to-day use, and I have been using it personally with far fewer problems than I ever encountered with OS 9, so I am always interested when I come across musicians who are still on OS 9 to discover the reasons why they haven't yet switched over.

We investigate the problems and provide some solutions.

In recent months, SOS's on-line Mac forum has highlighted the difficulty with achieving the same number of channels of audio I/O under Mac OS X and Logic that were possible under OS 9.
