faster pots response?

faster pots response?

2007-01-16 by the19thbear

is it possible to hack the bcf2000 so the pots&faders will respond 
faster??

thanks!

the bcf will respond as fast as you like, its all doen to your 
soundcard latency. Mine is set to 5ms and the faders and knobs respond 
immediately.

Check your latency.

This is the achilles heel of the BC2000 series... The midi faders/knobs on other nonmotorized devices that I've used have all been much more responsive than those on my BCF2000.
As far as I know, there's no solution aside from altering the internal circuitry of the BC2000 unit.
Because of this problem, I never use my BCF2000 to control anything that I need to move fast... I only use it to control the channel volume levels in Ableton (which are always adjusted slowly and infrequently).

It doesn't matter how low the latency on my sound card is set (I've gone as low as 3 ms). I've run a test comparing the nonmotorized faders on my kurzweil PC2X keyboard with the faders and rotaries on my BCF2000, under identical circumstances. The faders on the PC2X are as very responsive, leaving nothing to be desired as far as I can tell. The faders and rotaries on the BCF2000's responsiveness is choppy as hell when they're moved fast.
To be fair, I've tried using other motorized faders on different units... they are similarly unresponsive (i tried a mixing board with motorized faders at guitar center). I checked their setup, and their latency was around 3 ms, so I know that this unresonsiveness is not arising due to latency from the sound card. It seems to me like units with motorized faders (and the pots too on my BCF2000) are inherently unresponsive, why I don't know... probably engineering idiocy.

What does soundcard latency has to do with midi data? ASAIK, the BCF/BCR2000
units send midi data to the computer. I think souncard latency is a
different matter.. What I have noticed is more of a "graphic latency" if you
know what I mean. When I move the pots the sound obeys but the screen is
slow. This disappeared when I upgraded my computer and graphic card. Just my
2 cents..

Cheers

What do you mean by \u201csmoothness\u201d? In what context are you talking about? I don\u2019t understand very well what you mean\u2026 Maybe you could try to explain differently\u2026

is there a vst plugin like a midi "smoothener" if you get my point.. I dont care if my pots/faders are 100& accurate, i just want smoothness! is there a software solution for duing this??

like sending the midi messages through a "lowpass filter" to soften things up... i dont think this can be done in real life, but i hop you know what i mean.

thanks!

RE: [bc2000] Re: faster pots response?

What specs is your computer? (including chip, motherboard, graphic card, ram, etc)

What soft do you use?

Is the unit connected via Midi or USB?

i mean i get choppy response when i move the faders quickly, is there a way to smoothen the choppyness out?? lets say: i move the fader fast, from 0 to 127, and all the fader sends is 0,3,6,9,23,45,77,100,127. instead of 0,1,2,3,4,5,6---etc, up to127.

i want to smoothen it out so i get ALL the values, and not only some...

hope that makes sence...

thanks :)

Hi Troel
use MidiOx to check what time each of the Midi messages is being
logged at (the long number on the left of the input monitor - called
TIMESTAMP) 
If the numbers are close together then you are turning the knob really
fast 
Midi works at 31250 bits per second
Divide by 10 (there is a start and stop bit plus the 8 bits of data) 
So 3125 bytes per second is the best MIDI can do.
So for a CC message divide this by 3.
1041 three byte messages per second is the best MIDI can do.
This is better than 1mS per message
I'm getting about 4 to 5mS between messages on my BCR2000 with a CC
message. The biggest gap is 4 in the data. 7F 7D 7C 7A 78 etc

Do you have the control setup with a strange resolution? - check your
sysex dump of the patch you are using. 
should read 
.resolution 96 96 96 96
for a smooth control.
(I use the Birdy editor. Send the patch to it and look at the report tab )

Hope this helps
