Hi
I am very satisfied with SD2 – but wonder if anything might be worth upgrading to SD3 engine due to SRC:
#1. Does SD3 allow selecting SRC algorithms to use for playback and rendering?
Thinking one algo for each, to decide for yourself about performance/cpu.
Some sample based engines allow that.
#2. Can you install or preconvert all samples to like 48k – so no rrealtime SRC is needed when running projects at 48k?
Thinking either conversions made by SD itself – or I can do it using a batch conversion of what I know is really high quality conversion.
#3. Can SD3 use SD2 stuff as they are?
I will not consider using 200 GB just for drum samples, very happy with SD2 stuff and reasonable size on it all preloaded in memory and all.
I have the Avatar, Custom & Vintage and Roots sticks.
Thank you for any response on this.
Hi,
I’ll answer as best I can.
#1 No, there’s no real-time sample rate conversion going on while you playback. The SRC happens when loading the samples into RAM, then they are held there until unloaded.
#2 Short answer: No.
#3 Yes and IMHO better. From my own experience I think SD3 loads the old SDX:s faster and I simply love all the new features I get in SD3.
BR,
John

Thanks for a extensive and good response.
I got impression from Olle two years ago, when I reported a crash bug(2.4.1) – which was to do with init of sample rate conversion when loading a user preset. He said it takes a little extra cpu – but not so much.
Thereby ability to choose algo – but seems I got it wrong then.

“When you run a sample rate other than 44.1kHz there are ‘resamplers’
at the outputs that convert from 44.1 to whatever is used in your
project. “
“Regarding your questions, the adaptation to a different sample rate
in the host is done by resamplers at the outputs of S2. They
are always high quality and eat up a sizeable portion of a CPU
core if you use all outputs and a sample rate other than 44.1kHz.”
“We offer two version when
you pitch sounds, though, ‘Fix:ed and un-Fix:ed’. The Fix:ed
sounds are resampled in memory using that same high quality
algorithm while the un-Fix:ed sounds are interpolated on the
fly.”
Or is it different in SD2 and SD3?
Hi,
it was a sloppy answer I gave you, sorry about that. Even though I am labeled as “Technical Advisor” I’m not that technical, obviously. 😉
The principle would be the same but I imagine improved, since it has been several years in between developing the two plugins.
Tuning that is Processed (formerly Fixed Pitch), is done in RAM, though.
I hope Olle chimes in if there’s more to add (or to correct me).
BR,
John

No worries. Thanks for your response.
It sounds like smart move to do like you suggested, if regular kit staying on original or some fixed tunings – are made at load time.
But maybe dynamic articulations are done in realtime, to make every hit a little different than previous, and need to be made in realtime or use a lot of memory duplicating with variations or similar.
>Or is it different in SD2 and SD3?
SD3 and SD2 work the same in this regard.
SD3 has an alternative high quality pitch option for tuning toms, though.

OK, thank you for response on this.
Running 7 stereo outs normally at 48, I have not had any problems or anything – with SD2.
Just collecting points for possible upgrade down the line.
