[. . . ] When the sample frequency is set to 88. 2 or 96 kHz, the ADAT optical input and output operate in Sample Split mode, so the number of available channels is reduced from 8 to 4. 13. 2 Performance The 'Audio Performance' settings are especially important. Firstly, the number of channels should be changed from 8 to 18 so that all the Hammerfall DSP's inputs can be accessed. A very common problem is insufficient hard disk performance. If the first track is missing while recording multiple tracks, or the error message `Audio: Record Error' appears, the disk sub-system is too slow i. e. it is unable to write the audio data to the disk quickly enough. The problem can almost always be remedied by changing `Disk Block Buffer Size' from the default 64kB to 256kB. This is especially true if you want to record more than 12 tracks at the same time. 26 tracks are only possible after changing `Disk Block Buffer Size' to 256kB (depending on your computer). Please note that these parameters are only updated after clicking on `Apply'. User's Guide HDSP System Multiface © RME 22 The heyday of (expensive) SCSI hard disks in high-speed audio workstations is over. Today's cheap high-capacity EIDE disks allow continuous transfer rates of well over 10 MB per second. In practical terms, this is more than enough to record up to 24 simultaneous tracks using Cubase and Hammerfall!However, the hard disks have to work using Busmaster drivers. To activate the EIDE Busmaster mode in Windows 9x, open the Device Manager (Control Panel/System). Doubleclick on `Disk drives', then on the required hard disk(s). Select `DMA' in the Properties dialog, then restart Windows. Under Windows 2000/XP busmaster operation is default. The Buffer Size value in Hammerfall DSP's Settings dialog determines the latency (in this case the delay) between the audio application and the HDSP as well as general system stability. The higher the value, the more tracks can be recorded and played back simultaneously and the longer the system takes to react. At the given maximum of about 0. 2 seconds, you will not notice much delay at all - the system will still respond quickly and smoothly. Most present systems are unable to use the 1. 5 ms mode without audible clicks. For optimum reliability we recommend setting the highest latency possible, 186 ms. 13. 3 Synchronization To achieve sample-accuracy between the ADAT recorder and Hammerfall DSP while running Cubase, connect the ADAT sync output with the 9-pin Dtype sync input of the HDSP. The `Time Code' field in the Settings dialogue should now show the same position as the ADAT recorder. [. . . ] Apple and MacOS are registered trademarks of Apple Computer Inc.
