About

This tab includes information about the driver and the card’s firmware version.

Lock Registry uses a password to prevent changes of the settings stored in the registry. All

settings are still changeable temporarily. As the settings are always loaded from the registry

when starting the computer, this method provides an easy way to define a specific initial state of

the HDSP system.

11.2 Settings Dialog - Pitch

Usually soundcards and audio interfaces generate their internal clock (master mode) by a

quartz. Therefore the internal clock can be set to 44.1 kHz or 48 kHz, but not to a value in be-

tween. SteadyClock, RME's sensational Low Jitter Clock System, is based on a Direct Digital

Synthesizer (DDS). This superior circuitry can generate nearly any frequency with highest pre-

cision.

DDS has been implemented into the HDSPe MADI with regard to the needs of professional

video applications, as well as to maximum flexibility. The section Pitch includes both a list of

typical video frequencies (so called pull up/pull down at 0.1% and 4%) and a fader to freely

change the basic sample rate in steps of 1 Hz (!) over a range of +/- 5%.

The Pitch function requires the HDSPe MADI to be in clock mode Master! The frequency

setting will only be applied to this one specific card!

Changing the sample rate during record/playback often results in a loss of audio, or brings

up warning messages of the audio software. Therefore the desired sample rate should be

set at least coarsely before starting the software.

Coarse

Coarse modification in steps of 50 Hz

is done by clicking with the mouse to

the left and right of the fader knob.

Fine

Fine modification in steps of 1 Hz is

done by using the left/right cursor

keys.

Reset

Ctrl key plus left mouse click.

Application examples

Pitch allows for a simultaneous change of speed and tune during record and playback. From

alignment to other sources up to creative effects – everything is possible.

Pitch enables you to intentionally de-tune the complete DAW. This way, the DAW can match

instruments which have a wrong or unchangeable tuning.

Pitch allows for the change of the sample rate of all WDM devices at the same time. Since Vista

this is no longer possible via the audio program, thus requires a manual reconfiguration of all

WDM devices. Changing the sample rate from the Settings dialog solves this problem.
