Strange knob behaviour?

ThreeFingersOfLove · Posted: Fri Jan 04, 2008 4:25 am Post subject: Strange knob behaviour?

Hi,

only recently I have noticed that when I turn the following knobs:

1. Sustain from ENV3
2. Tempo/Clock
3. Knob #5 below the LCD
4. 24dB Lowpass volume in the Post Mixer

the corresponding value doesn't change smoothly but jumps here and there until the knob reaches its final destination. Even then it might play a bit, e.g. if it's maxed to 100 it might go 99.7, 99.5, 99.9, 100 in random order. It doesn't do this always. If I modulate any of the corresponding parameteres, e.g. if I modulate the tempo/clock from the modulation wheel the change is smooth. Confused

Any suggestions??

Unlikely, but the pots could be dirty. You could try cleaning them with a squirt of Servisol switch cleaner. If you dont want to open it, remove the knob and let some penetrate via the pot shaft.
Is there an audible effect? ( I usually judge things by ear, and rarely read the parameter values. ) Interesting that soft knob 5 also controls sustain.

I have tried cleaning these spots, but I am afraid it didn't do anything. Shall I have it serviced? Confused

Well i'm no electronics whizz but it seems you will need a suitably qualified technician to fix this problem. Are you on the mainland?

? you did all the softresets necceassy first and or a systemsoftware reinstall?
if not, might be worth trying,
otherwise ->survising /repair

i have the similar problem and besides that some of the buttons dont work sometimes. i ve done all resets and reinstalled the OS but still the same.
Any one with suggestions?

when under guarantee ,i would certainly send it to the servicestation when all other had failed as you describe.
and besides that to my opinion the numark. alesis servicetechnicien i encountered was very skilled, so don't be too afraid of those greasy fingers
. might also be some other internal hardware problem unsolvable by us normal folks.so my guess is contact them.

(21)A10412045700249 is my serial number.
I turned receive sysex from the global menu under midi tab to off and i didnt experience any of those things since, but i dont think it can be related to that, so i am wating those to happen anytime soon.

sure you don't have a midiloop?
if so try using only a midi in or out not both and see if he than functions oke ( even with sysex on)

Myconoid, thanx for the SN, I will check it against mine when I get home. I just want to see if the SNs are close to each other.

Well i've noticed the same problem too!

I was like WTF how i can't set the tempo to be exactly 120. I had to press the up and down arrows simultaneously to get "exact" values.
Also, when i tried to put oscs to be 41 i couldn't do that, it always went lil past it or lil less, up and down arrows didn't get me "exact" values in there.
Very weird and nasty, i didn't have much time to wonder trough it then and thought it's perhaps normal? God knows what affects what in that beast of hardware synth.

I'll check my sn too and post it.
It's manufactured some day, some month in 2002 though. =)
I guess the date display is US way which would be month/day/year as opposed to european style of day/month/year?

by the way, lil off topic but howcome all leds doesn't light always?
Can't remember if the behavior occurred more likely in mix mode.

The knob values and pages on the screen change more often when building a more complex patch.sometimes i cant even control a single parameter on the panel.I am sure it has to do with the digital components of the synth and i think they need to be replaced.

i don't have that exact experience , however strange ( hanging and undisplaying) things sometimes happen when editing a complex ( many modulations and controlroutes) patch .Specially when the trackinggenerator get involved too. always thought of it to be a problem of insufficient/ going to the limits of the processorcapacity. however on the most i don't regard it as such a problem and can live well with it.
( amazing, even the digital part of the a6 has analog aspects )

I just tested tempo parameters like 15 minutes when i had the spare time to fool around between recording stuff.

I could set hard value of 120 Beats and i wanted to make example the beat to be 119 per minute. It was impossible no matter what you did it was always off. Only other hard value i got was 125,00 beats per minute.
I'm not going to sequence anything from Andromeda when using internal tempo but anyway... this is definitely not normal right? I mean c'mon.

Closest i got it to be 119 was 119,045 and some other tempos varied with almost 0.500 bpm. I tested with only one patch ( i had midi connected with no filters on the other end so i didn't want to change patches ). I haven't reset andro and will experiment more tomorrow.

I'll definitely won't send it to repairment yet since it has many years of warranty left. Build date is 4/12/2002 and s/n is
(21)A1611045700638

45700 in serial would seem to be constant ( based on mycon and my serials lol ) on serial and perhaps could be code for manufacturing facility??

Threefingers could you post your S/N for the curiosity of it please?
Or PM it to me if you don't wanna give it publicly =)

Hi Threefingers.

Thank you for clearing that out.

If it really is "supposed" to work that way then i take it as it is and kiss my andro again for having one. Makes me really amused hahaha =P
I guess it's just the word *engineers... Yes, pun intented. =)

Arpeggiator or sequencer has made my andro to freeze couple times so sequencing externally is definitely something i'd do when in live. Booting andro takes up long time because my andro doesn't boot up if turned on too quickly, it hangs up.

This is offtopic but have you guys seen any cheapy good hardware sequencers ( needs to have just midi and ofcourse very big note/song memory ) lately? When i look up some recent stuff they all seem to have all kinds of un-necessary features that raises the price big time.
I'm looking for a prince range of 300 euros max.

Yeah please mail the s/n you have Threefingers.

Oh yeah! Threefingers or anybode, can you guys test this issue ( issue of exact values ) with osc tuning too please? Since i once couldn't get exactly 41 and othertime i did got it. =P I just wanted to know if this is normal andro behavior too =)

Hi there!

best thing is not to look at the display too much but go for your ears.
sometimes it's difficult to loosen myself of the screen , i know , but it's well worth it.
on the other hand a thorough study of your instrument is always nice too.
think the problem might be due to dusty contacts or digital vulnerabilities.
anyway , is it really a problem , and if so , is there a workaround for it ?

Hi.

Threefinger: I never autotune anymore, very rarely, so since autotune tunes everything else almost too, it could be that. I just let my andro warm up 20 minutes and go for it. =) I have both tunings on at the moment.

Sunny: No it's not a problem at all with my skills ( there really ain't yet much when it comes to programming ) and i'll test it tomorrow again to see if i can make that behavior come back and if, go off too.
