Ive already created this topic during beta phase. But i couldnt replicate this bug.
Now i encountered it again.
So if you wanna test it, open attached Redux Instrument and add RES. It will horribly peak and make almost no sound, adding drive will help a bit.
Ive heard something about DC offset problem so ive tried adding DC device before filter. Play with it, it makes interesting things
Activating Auto DC helps a lot (and create interesting but unwated phasing).
So some simillar function should be implemented in 4P Diode filter maybe?
If you’ve generated these samples yourself, then look at the process that was used to create them, and try to see where this bad DC offset/bias is being introduced in the first place.
WTF! When i re-open uploaded instrument there is no bug iam talking about.
I get you, but no other FX does this:
ive got drum loop with these samples, ive inserted eq, compressor. No problem here.
I inserted moog analog filter. No problem here.
I inserted 4p diode filter. Sound is gone and Redux is showing horrible peaking (moving by cutoff makes some weird sounds on certain frequencies).
I see that 4p filter has default resonance about 20%. So i lowered it, sound was back. When it got above 20% sound is gone, adding drive attentuates a signal and sound is going back, even it is sounding horrible.
If it is feature of 4p diode i thing that it shouldnt have default res bigger than 0 because it will confuse anybody with bad DC samples.
Thank you, it is amazing filter.
It generally should not happen with the compressors (or other volume based devices) as they are simply shaping the signal amplitude, and not doing anything special with some form of feedback (except if you have insane gain boosts, I guess).
However, plenty of the other DSP effects will do this quite easily.
Chorus / Comb Filter / Delay / Flanger / Phaser, with feedback turned up moderately high.
EQ 5 / EQ 10 / Mixer EQ, with a moderate amount of gain boost in the lower frequencies (still happens in other bands, but most easily in the low bands where there’s more energy).
Reverb with large room size / mpReverb with long duration.
Of course, each device works differently, and each filter algorithm works differently. Nobody is denying that. Heck, maybe some of the math can be tweaked slightly, I dunno.
Nevertheless, the problem is clearly with your sample material. Crap in = crap out. So just fix the samples and these problems should disappear immediately.
At the very least, you can process the samples with a simple Butterworth 8n highpass filter with cutoff set to minimum (or insert this as the very first DSP in your chain if you want to be lazy), and it should get rid of most of the problems.
A DC filter is simply a basic highpass after all, so the butterworth will give you pretty nice results.
That looks pretty neat indeed, thanks dblue! Now time for a ninja FR: Wouldn’t it be awesome if we were able to see those waveforms live in track scopes (a la s(m)exoscope)?
