I just wanted to say that Cantatis released new drivers for Overture sound card. I'm sitting jawdropped. You may ask why? I'll tell you. So far, I haven't been able to go below 1024 samples in adaptive mode and now I'm playing at 32 samples and Q1=-4 with QAP - no clicks  Why am I writing this? To confirm my previous hypothesis, that drivers' performance is the most important thing when it comes to low latency playback. Of course, Peter knew that before  |

I've just flashed my Cantatis Overture sound card to Audiotrak Prodigy 7.1 hifi and it's working! Native ASIO drivers and KS work, even with 48 samples, There is one problem though:
- 44kHz (88,2,176) playback works, 48kHz (and multipliers that is 96,192) don't work properly. It's like listening to music in 'slow motion'. I guess that Prodigy 7.1 hifi has different clock on board for 48 and its multipliers.
I'd be very greatful if someone with Juli@ card could take a picture of EEPROM offsets. Juli@ has the same clocks as Cantatis, so my assumption is that it'd work for 48kHz playback as well.
* In order to do so, you need to run eeprw.exe (enclosed) in 'real' DOS mode, press 9 and take a picture of Juli@'s offsets. That's it, it'd take few seconds. (enclosed you will see EEPROM for Cantatis. I need offset values for JULi@)
* Note that eeprw works only under 'real' DOS mode, you can't run it from windows. In order to run DOS, there is a tool called HP USB Disk Storage Format Tool + win98boot files (enclosed). With these 2 things you can prepare bootable usb flash. After a 'start disk' is created, copy eeprw to your flash drive, restart pc and boot from it.
Thank you in advance for help,
Marcin

Guys from Cantatis finally gave me some valueable tip I don't use their control panel, because it doesn't work in W2008 at all. I installed the drivers only. This is very simple tweak and for me - a life saver!!! What you need to do is: Search for the following registry keys in regedit: VA_CPLAutoSR (set to 0 = no auto sample rate, 1 = auto sample rate) VA_CPLSelectSR (set as follows, in hexadecimal, I set to 0x0e that is 192kHz): 0x00: 48 KHz (default) 0x01: 24 KHz 0x02: 12 KHz 0x03: 9.6 KHz 0x04: 32 KHz 0x05: 16 KHz 0x06: 8 KHz 0x07: 96 KHz 0x0E: 192 KHz 0x0f: 64 KHz 0x08: 44.1 KHz 0x09: 22.05 KHz 0x0A: 11.025 KHz 0x0B: 88.2 KHz 0x0C: 176.4 KHz Now I don't have to change the damn thing every time I want to listen to some different sample rates stuff. Enjoy! Marcin |
