Appendix III Optional Features
Pyramix DSD / DXD / SACD
Pyramix v10 supports 64 IO of DXD/DSD64/DXD128/DSD256.
Note: This only applies to 8FS/DXD or DSD. 1FS capability is still 384 Live I/O (768 simultaneous).
Requirements:
• Pyramix v10
• A Merging Technologies Turnkey System running Windows 7 Professional 64-bit
• MassCore 256 + Key
• System configuration based on Intel Core i7-4790 or above
• SSD required (Recommended 4 x SSD Crucial® M550 disks configured in Raid 0 / 64k block size) or 4x Cru-
cial® MX200 1TB 2.5” SSD in Raid 0 / 64k or SSD-SAMSUNG MZ1000 available on Merging price list)
• MassCore must be set to Low latency mode
• Record in single media (not one file per track)
• For better performance disable Waveform Generation while recording
•Use a Windows 7 Basic Theme (avoid Windows 7 Aero)
Note: DSD256 or DSD128 (DSDIFF) in a DXD project requires a lot of resources therefore the
number of I/Os may need to be reduced in such a missmatched format Record scenario. For Edit-
ing please be aware that edits such as CrossFade require twice the processing resources, so Track
counts must be divided by two in such a case. Crossfading a Media file with itself is not recom-
mended.
Merging Technologies Horus
Merging Technologies Horus is the ideal solution to DSD and DXD interfacing.
The tables below shows the capabilities you can expect:
For complete information about Horus please see its own documentation and for full information about DSD /
DXD and SACD please see the forthcoming DSD / DXD / SACD Guide.
Note: Recording DXD using the Horus / Hapi A to D converters in DSD is very intensive in CPU
processing with AD in DSD. In such a scenario MassCore SMP users may need to allocate more
Cores to Windows than to MassCore (e.g. 6 Windows and 2 MassCore).

Merging RAVENNA MassCore - DXD/DSD Specifications
(Requires Pyramix v10 and above, with 4xSSD in RAID 0, Windows 7 Basic Theme and a Merging Turnkey i7 4790 or better.)
* Projects have no tracks limitation, the specified playback track value is based on the tracks containing media.
*** Playback track count without Edits (such as crossfades). When editing with Crossfades performance can reduce significantly and stalls may
occur, we recommend not crossfading between the same media source and if performance cannot be sustained to convert your medias to DXD
during the editing work, you could consider relinking to the DSD256 medias for the final processing.
** Requires optimal configuration (turnkey) with MassCore SMP (benchmarks were performed in Hyperthreaded mode
with a 4 Cores to MassCore and 4 cores to Windows repartition)
