There’s no need to split the projects into “sister-sessions” just to avoid crashing the machine. And thanks to DSP-based, dedicated processing, you never have to be afraid to overload the system with complex mixes, thus avoiding the inherent unreliability of systems based on CPU only.

64ch audio I/O capacity per card is also doubled from previous HD Accel-generation.Ĭombined with the speed advantages introduced in new Pro Tools Ultimate software – like disk cache which loads the whole session in RAM and realtime CPU-based fades – HDX coupled with a modern Mac with SSD boot drive and decent amount of RAM is an absolute speed monster. This is also a massive enhancement from Pro Tools HD Accel which forced you to dedicate DSP chips for Pro Tools Mixer. Additionally, the built-in FPGA chip frees all 18 DSP chips per card for actual signal processing as the behind the scenes audio routing management is handled by the FPGA. On many types of plug-ins, the speed advantage is even more significant because the modern DSP chips have way more RAM than the previous Motorola 56k chips that were used in HD Accel. In a nutshell HDX offers up to 5 times the DSP power and 4 times longer delay compensation than the HD Accel card of the previous flagship system, Pro Tools HD. One of these days, we'll be able enter delays in samples in Pro Tools and finally sample rate of a session won't matter.Pro Tools HDX is Avid’s flagship DSP-based Digital Audio Workstation, the world’s standard DAW platform for the most demanding projects in music, film and post production. So you could do the math from the documented latencies, but it's just faster to measure. For instance, on a full size MTRX with the A/D and D/A cards, I know my latency at 48kHz needs to be entered at 1.08ms on the H/W Insert Delay tab (this is accurate to the sample.) I just round-tripped the signal and measured. And there are some delays that are fixed no matter what sample rate and some that vary depending on sample rate. And I believe there is a FAQ or KB on Avid that also documents this. Avid's Jeff Komar (IIRC) has posted the complete delay specs for each type of i/o on these forums. For instance Pro Tools only sees HDX ch 1 but in DADman, HDX ch 1 could be patched to analogue ins/outs or to MADI ins/outs. In essence, since Pro Tools does not know what you've patched to what inside of DADman, for a hardware insert you need to put the compensation inside Pro Tools. Does the MTRX track this additional latency and relay it to Pro Tools? would Pro Tools compensate that delay properly? Or would you need to manually enter the hardware delay for any channels being converted outside of the MTRX box itself? When using the MTRX through an HDX card how is latency/delay compensation handled for additional IO coming in through ADAT/Dante or Madi?Īs an example say you were using an I/O Insert in Pro Tools to connect to a hardware compressor, which was sending and receiving on channels allocated to a Madi or Dante device. When connecting to the MTRX as a Dante interface through a PCIE Dante card, (for use with another DAW outside of Pro Tools) Are ALL inputs and outputs of the MTRX available to the Dante network? Or are some channels only accessible via HDX?Ģ. If anyone with experience has time to let me know that would be greatly appreciated!ġ. I reached out to Avid sales and the person I spoke with couldn't give me an answer. We are thinking of switching to either an MTRX or MTRX Studio and there is a couple things I've been having trouble finding an answer to in documentation.
