Hi,
As mentioned, I am the developer of a software application for PDAudio.
You should have good results recording at 24/96 on newer systems recording to SD memory. I recommend the 624mHz systems now like the Dell X50v, hp hx4705, hp hx2750. The older H5100, H5500, and H2200 series (all 400mHz) work great recording to SD also. I'm not recommending recording to flac at 24/96 just yet.
We did have problems maintaining 24/96 using expansion packs and recording to compact flash, pc card drives and microdrives. Craig T. who has put up a lot of shows on bt.etree.org uses an older 3800 series and an expansion pack and a PCMCIA<->Addonics Pocket Exdrive. He has been having good success with it, and uses a method I developed called "update mode recording". I won't go into the details of that here, but it can make some configurations to work at 24/96.
Initially, we did have problems in software. These problems had to do with buffering and alignment of samples within the buffers. There are some things about the driver that I wish were a little more "application friendly", but I have been able to make adjustments accordingly. I was having some problem keeping 24-bit samples perfectly aligned. Early on, this resulted in white noise, and some jumpy or low levels in metering. Quality issues in the software have been addressed.
Also, to begin with, there was no way to monitor, but that has now been implemented. However, currently it is limited to the capabilities of the pocket pc hardware which is up to 16-bit 48kHz. Since monitoring is done digitally, there are latencies with it. It's better to monitor off the analog source.
SD is limited in practical storage capacity at 24/96. We get around this by using a media swap feature. You can actually remove the media while recording and put in another. The recording is stored to internal storage while swapping. This also works with expansion packs. The catch is that you have to be able to write to the internal file store at whatever rate you are recording. The file store is slower as it writes in a compressed format.
The media swap is a unique feature among recorders, and that is something that I think you won't see with the Microtracker. One thing about the pocket pc is that it is programmable and the programmer is designing the software with tapers in mind! Live2496 is designed for long continuous recording, and no loss of samples is important.
I am still working on the user interface, but I decided early on to put the emphasis on the basic recording function first to ensure that it handled it's primary function nicely.
If you have further questions I will be glad to answer here.
