OT.. anyone here use a Access Virus C?

OT.. anyone here use a Access Virus C?

2007-04-28 by gonzinigonz

Hi all
Sorry for off topic post but could do with a quick answer to a problem 
with a Virus C.
Getting some loud pops and clicks with the audio.
I think its a problem with the FX engine.
Can anyone tell me if they get zipper noise when they increase or 
decrease the delay time? or do they get a smooth glitch free transition?
Also sometimes i get a loud click if i turn the delay time down to 0 
then the same increasing it.
The same goes for the send knob, but only occasionally. 
Somethings not right but ive not got another one to compare it against.
Cheers guys
Gonz

I don't have one, but that's a very common problem with digital delays.
 The XL-7 has the same issue.  I had to write a special tempo filtering
algorithm to keep the tempo based delay from sounding horrible when
synced to MIDI clock (since the tap length would be constantly
changing).  Anyway, hopefully someone else with one can try it on
theirs...

Hi Aaron
I wasnt sure how good the delay was on the Virus C.
The loud clicking problem doesn't sound to me like an artifact of the 
changing delay time as such. Its much louder than the actual audio.
If you change the delay time on a Boss DD2 say its fairly clean and 
smooth. 
I think somethings not right with the hardware, maybe some ram dying on 
the FX DSP im thinking. 
Its been hard to isolate the problem as its not doing it as much as i 
remember hearing it round a friends.
Ive had it on for 48hours just churning out a preset with loads of fX 
on it. It only seems to play up when you manually change the delay time 
and sometimes the send level.
Saying that id ought to try modulating the delay time with one of the 
LFO's and see what that does on extreme settings.

How was the code written for the command stations out of interest?
Did you use custom tools  / software.

Cheers
Gonz

>>The loud clicking problem doesn't sound to me like an artifact of

I've been trying to use the midi-clocked delay in my emu modules since
they first appeared in the audity 2000, years ago. emu never seem to
have fixed this problem- it seems to be worse if your midi rig is more
complicated, but I still get the glitching/cracking sound even with
the midi clock source connected directly to the emu box (audity,
proteus, XL7, whatever).
the symptoms are that the emu box loses it's grip on incoming midi
clock ever so briefly- you can see this if you hook up a source of
midi clock to the emu & watch the tempo display. 
it doesn't seem to cause problems with pattern/beats/arpeggiator
playback- it's just the effects module that misbehaves, but you can
clearly see the tempo indication changing suddenly & then settling
down again. the audible effect varies, but can be like a loud click
which then echoes if you've got the delay feedback turned up.

I work around this, sighing, by using a preset on one channel to
"host" the effects settings, & set the tempo manually. I use program
changes to adjust the tempo during a set- sometimes within a piece if
I can co-ordinate the tempo change with nothing much going into the
effects sends. it's annoying- frustrating. I'd like to be able to do
smooth tempo changes; that's the whole point of using midi clocked
effects, after all. but even without tempo changes, clocking the emu's
delays over midi makes these huge clicks.

now- here's another midi clock problem I have with the XL7: my command
station sits in the midle of my midi rig, so it receives data from
keyboards & a couple of hardware sequencers. it is therefore slaved to
incoming clock. so far, so good. I can record patterns & parts into
it, just like it was a midi tape-deck.
but while I'm using it like this, I can't get it to pass the incoming
clock to it's output. it merges incoming note data onto either or both
of it's midi outputs, but not the clock. I have tried everything- I
know all the menus inside-out. it's a bug. I am using the latest
version of the o/s & it's definitely a mistake. no-one left at emu to
do anything about this now.... :-( anyone else seen this?

duncan.

Command Stations/P2500s do not echo incoming midi clocks. Also, if 
the E-Mu is at the end of a midi daisy chain, there is little or no 
timing reliability. I used to use a MOTU MIDI router (8 x 8 parallel 
port version) to avoid the daisy chain problem. 

I solved the problem of trying to sync gear with Sonar (and other 
clock producing gear--such as intelligent arrangers) by creating 
different Multisetups depending on whether the E-Mu was clock master 
or slave. I could not do this without the router.

As far as midi clocks/sync OS 2.0 still tops previous versions.

The Viruses are supposed to have a special algorithm to avoid just that, 
so its most likely not a software problem.

It does sound like hardware problem to me, maybe some DSP ram on the 
way out..
Im going to give it back to the owner and their going to give it a 
good work out as i dont have time here at the moment.
I said if it starts getting bad and reproducible then to try 
switching off the FX to see if that sorts it out.
