OT and bitstream 3x unwanted midi jumps

Hi folks,
actually, i was wandering how to avoid the unwanted jumps that the bitstream provoke when i change a group of settings.
the bitstream 3x keeps in mind, like a snapshot,the positions of the controlers.
there are 2 mode for the analog controlers behaviour in the bitstream, one to avoid these unwanted midi jumps, but still the OT keeps “jumping” from one group of settings to an other.
Weird isn’t it ?

Which parameters on the OT are changing unexpectedly when you chnage group on the B3X?

Are you using Automation functions (LFO, Arp, Motion Sampler) on the B3X?

all of them actually, even i choose the right analog behaviour of the 3x, jump or hook.

no i don’t for the moment, but i know this would provoke jumps with the lfo, arp or motion, but it’s normal here.

What MIDI connections have you made in your set-up?

What MIDI connections have you made in your set-up?

octatrack midi out (master clock) : bistream in (external sync)
bitsream out 1 : octatrack in
bitstream out 2 : nord modular g2 in

i sent a mail to the wave idea HQ, and jerome told me that the bitstream doesn’t midi learn in live … i wanted to know if it’s possible for the bitstream to know the position of the controlled parameter to avoid these jumps but no … it ain’t possible.

an example of my issue for you to understand :
bitstream knob 1 midi 8 - octa track1 pitch
bitstream knob 1 @ 127 = octa track1 pitch @ +64
then …
bitstream knob 1 midi 9 - octa track2 pitch
bitstream knob1 @ 42 = octa track2 pitch @+22
so … on the same knob
octa track 1 pitch @ +64
octa track 2 pitch @ + 22 … ok

i move the knob … back on one of these 2 channels, the hook mode should avoid these unwanted jump between the 2 positions but no …
one position indicates +127 meaning i must move the knob all the way up to get this control back …
any position the knob’s on, when i pass the +64 or 0 value it controls the OT … so provokes massive jumps between the 2 positions.
i hope my explanation is not too confused.

Ok, so we ignore the Nord, no point to stress about it.

So if I understand correctly, you have the Bitstream Out 1 connected to the Octatrack.

And you are wanting to use Knob 1 to control the Pitch parameter, but dependent on the channel that you select, controls Track 1 or Track 2 and so on?

There is also the Autosend function when you change group , if I dont remember bad

exactly but i don’t change the channel but the group
the channel is set within the group itself

There is also the Autosend function when you change group, if i don’t remember bad.

the autosend is common to all groups at start up only but not for the group changes

oups … i’ve just noticed that the “Autosend” function can be switched on-off on every single controler, knob, button, fader of the 3x.
in my case so in every groups and controlers it is ticked “on”

this “autosend” thing might solve it all ?
but it says “on startup” … of the bitstream ? or a groupe change ?
i’ll try …

sorry guys if you have lost your time, i hope not
thanks for your help

but actually … this “Autosend” function is killer

I didn’t really understand your explanation.

One more check:

Are you running firmware version 1.8? If so, you should ensure that you are using Hook mode for every control individually.

Is your OT sending MIDI Program Change messages to the B3X?

Are you sure that you are changing groups, and not changing scenes?

yes for the o.s
hook mode for every single controllers, knobs, faders, buttons etc etc

Is your OT sending MIDI Program Change messages to the B3X?

no absolutely not
only the clock

Are you sure that you are changing groups, and not changing scenes?

yeh 100%

i thinks i fixed the issue : the auto-send function which was ticked for every single controls of my 3x … i’ll have to untick them all

Let us know please, I am always plenty of curiosity when the manual says something and it’s not true… :stuck_out_tongue_winking_eye:

it reissues to me that phrase about a bumblebee that didn’t know it couldn’t fly due to its shape and weight …

i never said anything about the manual …
i was asking a question not pointing anything …
most of the times the problem comes from the user
i just forgot to untick the “auto-send” function on every single controls of the bitstream

it reissues to me that phrase about a bumblebee that didn’t know it couldn’t fly due to its shape and weight …

this is the answer you give to my first question ?


manners cost nothing … even on the web

I would love to own a bitstream controller…can’t believe they stopped making 'em. :frowning:

sorry drumfish, I wasn’t sarcastic at all.

maybe my English is bad and never meant to be mean at you, it’s not my way especially if I cant speak person-to-person.

My intention was to be constructive and you pointed opposition to my suggestion about auto-send in first chance. Then you found immediately that it could be the solution, even if it says “on startup”…

So I thought and spoke about the manual.

My bumblebee story was about the fact, in pure genuine and simple mood, that even an “authority” like the manual says something it is not always true…

You found sarcasm…it wasn’t - Imsorry

you can find one preatty cheap either, I paid mine €150 one month ago…

They had a lot of problems with the , i think. I bought it once New and sent it back thee times because the pot meters were skipping. After 3 times i decided i wanted my money back

Wow. :frowning:
