EQ sounds different in 48 and 96khz. Shouldn’t it still affect same frequencies as much? Ie. EQ’d bass has more high frequencies at highers sampling rates, but if EQ is removed it sounds the same no matter which if I use 48 or 96khz.
Just wondering…
If the sample is “sampled” at 48 it does not really have no reason to sound different when played at 96…
adding EQ DSP on a 96Khz machine (Renoise) while playing a 48Khz sampled waveform (the bass) -does- affect the sound…
Want to do a nice experiment? Try rendering your bass track + (hard)EQ at 96khz … save it as a file… and then downsample it to 48khz in some editor and keep an eye open for the results…
That should sound different than simply adding EQ DSP on a 48khz session…
(can somebody check my logic here, please?)
Yeah, of course this affects the sound, because ½ of the samples are drop out. But does this really got to do with the case where I add a EQ to a VST in Renoise@96khz and save the song. Then I quit Renoise, load it up again, and open the song to Renoise, this time running @48khz, and get a different sound from EQ?
Sorry, I did not fully understand your post, trying hard tho. 
And not only with native EQ.
I had an ideas that the way it sounded in 1.281 were less correct than in 1.5
I’m happy it sounds correct at the minimum samplerate the sample was sampled on.
It’s a bit pale to work with 96khz and when you actually drop down a level, your song sounds much more ruffed up while all samples supposed to be 48Khz.
With percussion, the interpolation differences are understandable, with baselines not.
It could be up the VSTi you’re using simply does not goes beyond 48Khz… all in all I guess not all VSTi are designed to work at 96Khz (?) 
I don’t see anything strange in stuff sounding different from one samplingrate to another… but that’s probably because I’m not working on a 96 Khz capable soundcard yet so I don’t see the problem…
