Bc2000 (for the BCF2000 & BCR2000)

Hi everyone, I have a BCR2000 for about 6 months. When I "spin" the push encoders in an attempt to change values very fast they don't respond as expected, sometimes only moving by a few values and in a very erratic fashion.  Is this because they are optical controls or does this sound like a fault.  All the push encoders perform in this way.  I have tried different settings for the encoders but get the same results including altering the acceleration settings through sysex.  If I move the encoder at a slower speed it operates as expected but was hoping to operate at speed with these controls.  

thanks
Alan

You're talking about your BCR's "PUSH encoders". So does the problem occur only with the 8 knobs in the top row or with ALL encoders?
In any case I can't imagine that all 8 (or 32) encoders are physically defective. There might be something wrong with the "general" electronics of your BCR, but that doesn't seem very likely either.

Are you sure you're using the correct SysEx messages?
Have you looked at "BC MIDI Implementation.pdf" (available from my website http://home.kpn.nl/f2hmjvandenberg281/ ), section 17.3 ?
If you're using BC Manager, it should be very easy to experiment with different resolutions.

I'm not sure how fast your "very fast" is, but I suppose that at extreme speeds the encoders might indeed start to behave erratically - I've never tried.
But if you set the ".resolution" parameter(s) reasonably high, it shouldn't be necessary to turn the knobs extremely fast.

Hope this helps,
Mark.

Hi Mark, thanks for getting back to me.  It's just the top 8 push encoders that this happens on.  I am using a mac so BC Manager is not an option but I have Parallels' installed so I might try it that way.  It happens on default presets and also ones where I have modified the acceleration settings.

When I say "spin" I mean that as the push encoders have freer movement than the regular encoders you can spin them rather than manual moving them from min to max.  I have used this method on other controllers.

I only became aware of this issue as I have started Djing and want to do fast filter sweeps and rapid control of other parameters.  I know I can use the bottom controls but just wanted to sort this issue out.

I will try what you suggest and experiment some more.

Thanks.
