Too lazy to bother pulling out the Tascam or moving the SC5000M near it, but just passing the player with keylock off through the X1800 set to 96khz, using a 24/96 RMAA test signal, recording that in Sound Forge, saving as 32/96 wav, and analyzing in RMAA:
A FFT spectrograph in Sound Forge of the sweep portion shows exactly the same harmonics in the videos on YouTube. In use, I also do not hear any new spurious tones with keylock on, either. So, SC5000M v3.0.0 seems to have identical sound processing to v1.3.1.
BTW, on the SC5000M you only need 48khz on the mixer it seems to roll off the ultrasonic crap⌠and you preserve a little more of what little treble you have compared to 44.1khz. So, DB4 and PPD 9000 (and that Vestax 580?) will fit right in alongside X1700 & X18xx series set at 48khz until some of this stuff is fixed. I wonder if v2.4 on the SC6000 still had ultrasonic stuff getting through.
It is disconcerting that for some reason they are not using the same audio DSP firmware code on the SC6000 as on the SC5000. Maybe something they were working on for the whole line that wasnât yet finished just got accidentally âpushedâ into some of the modelsâ firmwares ahead of schedule?
one more thing, these distortions can be very easily seen on the spectrum. this file was recorded using 2x sc6000m, firmware 2.4.0 is installed on one player, firmware 3.0.0 on the second. key lock has been turned on and the decks are in sync.
What styles of music do you guys mix? Iâm curious as I know different genres and sounds cause more problems than others.
I get an awful sound with any filtered kick in Seratoâs Pitch ân Time. Claptone - No Eyes causes a farty duck quacking sound in SDJ due to the kick.
for me itâs techno, melodic techno, progressive, ⌠but the problem occurs even if the pitch is in the 0 position and the key lock is on. If the key lock is turned off, then the distortion of the sound disappears. also this bug is not reproduced in 2.4
Is there any update from Denon on this? Most of my music (I use Beatport streaming primarily, and melodic house / trance predominantly) is unplayable on 3.0.0 with key lock turned on (even with pitch at zero).
I have the same issue with my Prime 4 and Prime Go. Even opened a ticket with the support but they never got back with an answer. Do you guys have a timeframe of the solution? On my ticket, I wrote as a âDownsamplingâ, because at the time, I did not tested it turning off the Key Lock
Wow⌠support tickets. Maybe a bunch of us should have done formal support tickets for the roll-off of the original audio content and addition of IMD and ultrasonic noise on the SC5000 non-Ms and Ms when keylock is off and at zero pitch as soon as that was first discovered⌠might have gotten more attention and an actual resolution sooner. Itâs interesting that the baseline you guys are just trying to get back to is still poor-quality processing, equivalent to listening to a Sony Discman set to Car Mode and passing through a guitar distortion pedal set to low. Remember during the analyses to compare the old firmwareâs digital output to the original audio files or even the competitionâs digital output.
