What is the internal native sample rate of the Integra?

30 Jul 2014, 11:37
Hello,

I have my Integra 7 pluged in using SPDIF. I have quite a complex studio and cannot (and would never) clock my DAW to the Integra. Luckily, my Lynx sound card has SRC (sample rate conversion) on the digital input, so i can use any sample rate that the Integra outputs without having to use the I7 as my master clock (I use Apogee)

Now, I run my DAW (Cubase) at 96K - so initially i said, OK ill run the Integra at 96K as well and just use SRC to sync it. Theen I started thinking if the Integra was just 44.1 internal anyway, I would be doing SRC twice for no reason.

Anyway, question is, what are the internal sample of the Integra? 44.1 or 96? I understand that you can CHOOSE the output sample rate, but what is the native sample rate? What rate would avoid sample rate conversion inside the Integra? Thanks!

I don´t really know the answer to your question, but if the internal rate is 96k you could test it by using the PWM aliasing of the SN synth engine. The aliasing from C6 onward should vanish with such a high sampling rate if the wave is produced by calculating it. If the waveform is produced by just playing samples with a higher frequency it would not work. I have no access to my Integra at the moment and cannot test it myself.

I know that the JD-990 was 44.1. I know that even though the XV-5080 took the old JD cards, it played them at a compressed, lesser rate (for whatever reason.)

I just don't want to convert the output twice. Right now I am running the Intregra at 44.1 and it sounds amazing. The difference in the SPDIF output compared to the analog outputs is large.

After some testing it seems there is no effect. Changing the sampling freq to 96kHz does nothing to the sound. There is still aliasing with the PWM waves in the SN-S engine. :( The original samples are 44.1 kHz it seems. Korgs synthesizer Apps don't produce aliasing for PWM oscs.

I think you are right. For some reason my sound card wont convert the 96K output from the I7 anyway. Only 44.1 into a 96K project. That works for me!

Would still REALLY, REALLY love to know the internal sample rate of all the different Integra synths. ANYONE???
