I’ve loaded my BB5 entry into Renoise 1.9 and noticed sound differences (especially in the intro) between it and version 1.8. Any idea, what this might be? All tests were rendered with the same settings… simply playing the song in Renoise makes this obvious too.
Here are two screenshots of the waveform comparing both versions. When quickly switching between them in an image viewer (or browser tabs), the difference is clearly visible.
Yes, i’ve turned all mastering options off in both versions. I suspect it might be the filter device. The beginning of the waveforms seem to match. When fading in the filter bleeps slowly, it seems to get more obvious over time.
In the case of boombox: first pattern, the track to the left of the hihats. The second delay on that track has the delay values automated via LFO, and that seems to be it.
If you mean track 05, then thats clearly the delay time smoothing (as pysj said):
Automating delays in Renoise < 1.9 causes clicks. We fixed this in 1.9 by ramping the delay times. Thats why it sounds a bit as if you are pitching the delays up and down…
I’ve done some more tests. Deactivating all delays made the difference nearly not audible anymore, so i guess it must be the reason. Why nearly? I did two renders of the exact same pattern of the song in 1.8, and i got two subtle different versions. Wondering why, since i haven’t used any LFOs or random values. No complaint for this from me though, guess it’s some effect not being constant.
Regarding the delays… i haven’t automated any of them, but it seems the ramping is applied anyway.
On a side note… i’ve noticed a quite drastic speed difference, when rendering in 1.8 and 1.9 the same pattern. 1.8 renders the same part a lot faster than 1.9 here (using low priority).
It doesn’t seem slower on high priority though, does it? I guess that just means that low priority now really is low priority/background. If so I’d kinda like that, but maybe an additional “medium/normal priority” setting wouldn’t hurt.
