Elektron Musical Instruments

Hi all, I'm new here. I bought a MD one month ago, and from time to 
time, whenever I press a button it reacts as if I had pressed it 
twice: this makes play go play, then pause; or makes a drum sound 
twice.

Its not a big deal as it happens every once in a while, but I'd like 
to know if anyone else as this problem. I'm a little scared of what 
could happen using it live.

Maybe its the button layer defective? could it be a software thing 
(dont think so)? What do you guys reccomend?

Also another question, why is the sid station so expensive? what 
makes it so special?

Anyways, thanks in advance

I've not heard of this before.  maybe you should contact Elektron 
support.

it's special because it has the Commodore 64 sound chip and a 
synthesizer
with a wonderful easy-to-use OS built around it.  it's expensive 
because only
like 1000 of them were made before production stopped due to the lack
of Sid chips in existence.  and if you think that they're expensive, 
you should
see when a Ninja version pops up (it's a black Sidstation, only 50 were
made); they go for double what normal Sidstations go for.

Looks like a midi loop.

i have this problem too.. its not that irritating.. imho its because
you didnt press it firmly enough.. if you press it gently the
connection gets touched twice.. and thus gets triggered twice..

mmmm... I think you're right. Dunno why, but I feel better now.


Thanks for all answers!

Hi, this is called 'bounce'. When you press/flick any mechanical switch,
there is actually a period of time where it goes on-off-on-off-on-off etc
really quickly before it settles into whatever position you meant for it
to be in.

It could be a software thing in that this bounce time exceeded what the
software expected, or, a hardware thing in that it actually did get two
physical presses from you (bounce time not the issue in this case) and you
couldn't tell.

Could be a faulty button, or the button may just be on the weird side of
the acceptable-performance spectrum. The buttons are all going to vary
with their bounce time relative to each other (and their quality), and the
programmer has to balance overall responsiveness with meeting the (tight)
timing requirements of other chips besides the mcu/cpu. Once-and-a-while
is okay and 'normal', as in nothing is 'broken', but that button may have
a shorter lifespan than the others and may act up more later - or not. (No
button works forever; most lifespans for tact switches are 50K~1M presses
depending on model.)

What point is too much acting up is very relative - wouldn't bother
getting the button replaced unless it actually got to an unusable state.
Someone said be more firm when applying pressure and that's probably the
best bet.

Whoa! Mark, your are the best. Thanks for the detailed explanation. 
Amazing.
