A little bit of sound passing thru closed filters Subject description: Am I doing something wrong? |
|
|
Can anyone explain how to completely close the filters? I'm tryimg to trouble shoot if its my settings, my headphones port, or my Andy.
If someone could try this and let me know what they hear, I would appreiciate it !
This is what I'm doing:
0. I plug in headphones into the headphones port, and turn the main volume & voice mix volume knobs all the way up.
1. Init a blank Program.
2. Turn all oscillators off besides OSC1 Saw Wave.
3. Turn Filter 2 knob all the way to the left.
4. Turn Filt 2 keytrack all the way down.
5. Turn volume & voice knobs all the way up
And I can still hear oscillator one coming thru very very faintly, almost like bit-crushed. Can anyone else replicate/explain this?
Cheers and Thanks
EDIT: All these views, and no one who's viewed it has an Andromeda + Headphones?..... |

I'll try replicating this when I get near my Andromeda next, but this doesn't sound right to me... |

very faint might be no problem.
did you do the vca callibration once ? ( tuning menu )
is the prefilter off ( last knob down on the postfiltermixersection) |

Yes I've done a VCA Tuning, and I've also done a hard-reset.
I have not touched the pre or post filter mix. I've only done EXACTLY what I've listed in the steps above.
If someone could replicate those 6 steps (w/ the A6 Headphone Jack, I think this might be important), and tell me what they hear, I would appreciate it
I am trying to troubleshoot if Its the Headphone Port, my Ignorance of A6 Programming, or my A6 itself. I am a bit worried, because we pay a pretty penny for these machines , and when I want a filter to be completely closed, I want it to be completely closed
Thanks for the replies everyone, and P.S. Sunny I am a fan of your posts |

with analog completely off, isn't always completely off...
especially not when all volumes are turned up completely.
is it with both filters in serial, or parallel !?
is the leaking thru filter 1 or two or both?how are the other oscilators ?
what about other patches ?
are all effects off /does he also leak from the aux when routed that way?
as it's leaking thru in the analog path then it should be on all inputs when routed appropriately.., the headphones is the same as the main/ with extra amplification i would guess
reducing the filter offset, does it help ?
before thinking of things like a bad capacitator, i'd first would like to check these things as most of the time it's a settingthing due to the complexity of the machine .
when behind my a6 i'll definitely try to reproduce the problem |

I understand
Quote: | is it with both filters in serial, or parallel ? |
I am just starting a blank patch / program, and turning all the wave forms off except osc1 saw, so Im honestly not sure if the filters are in parallel or serial in a new program, but you bring up a valid point.
Quote: | is the leaking thru filter 1 or two or both?how are the othe oscilators ? |
When initializing a new program, It seems Filter 2 is the one which affects cutoff.
Quote: | what about other patches ? |
I think I first noticed this issue on other patches, so I brought out my headphones and started making this thread lol

Blank Init Program. Then all the waveforms are turned off except osc1 saw wave. No Effects.

Ill try this when I get home from work. I remember trying this and I cant remember the results. Off the top of my head I want to say I still heard a little something.

I agree with you. Im sure it's my lack of knowledge with the filters, and if that is the case, if someone could reproduce my steps above, and then add some additional steps for me to follow to close the filter completely, that would be awesome =]

most patches consist of two filters involved, you can see by the light if they are serial or parallel. first try to put them on serial.
i did upload some new defultpatch somewhere around here if you'll find it and can install it that would maybe also help as lots of things on the "normal" defaultpatch are already connected making the search more difficult.
overall: put the filters in serial / make absolutelu sure that all outputlevels of the filters are turned down in the postmixer, and also that no, NO, signal is involved from the bypass-prefilter knobs.
also see if the oscilator 1 b.e. is wset to lets say 1/3 or 1/2 ( 12 o clock )
effects completely turned off !
filtercutoffs to 0. / resonance 0
you should hear nothing now
now start with turning on only the postmix of filter 2 , to 1/2
etc
let us hear the results please |

did you read the manual, sorry to ask, about how the filters are configured and what all controls do in the different modes ?
look for difference between, serial/parallel/ notch
look for what all different parameters do in the postfiltersection
the defaultpatch i made was here:
http://electro-music.com/forum/viewtopic.php?highlight=testing&t=4200
http://electro-music.com/forum/download.php?id=1178
http://electro-music.com/forum/download.php?id=1176
overall advice:
see manual page 116 especially page 124
see manual page 189/190 and further
put filters on notch ( =parallel)
f1 only turn up lp( in postfiltermix)
f2 only turn up f2(in postfiltermix)
all the rest out !
turn up freq filter2cutoff to max ( still no sound or only very faint )
turn uo freq filter1 cutoff , only now you will hear sound
good luck |
