Bc2000 (for the BCF2000 & BCR2000)

Royce is great!

I am making good progress, once he showed me the commands.
Also, using the midiox to actually view the sysex coming out of the
vfx has been key, I did not use the sysex manual after that.
Royce showed the way.
I am able to move the command on the synth and transfer the sysex to
the bcreditor.  Then confirm the commands match, before moving on to
prevent the wrong command from getting in there.

I have my 3 envelopes mapped, quite a chore, and made the .showval
bar/off, which helps me remember which controls are envelops.
So major progress here, I will post a final product when finished.
Thanks so much, Royce, I thought I was going to dump this synth, now I
am having fun with it again! Yeah!

 Thanks both for keeping it online because I learned quite a bit
reading Kip's VX-BC escapades. Thanks Royce for being so helpful.

Well done. I just wish I had one to play around with.
Look forward to seeing the preset.

Question for the master.

Royce,

What about if I have a button I want to skip items?
I have a minmax 0 16 and I only want a few items, non contiguous?
I want a button to increment say 0, 3, 4, 7, 9, 10, 13, 14, 16.
No real pattern. There are selections in the list are ones that I
won't use.. and don't want to remember.
 
Ideas?

Kip

Well, not sure i want it on more than one button...
Same with the negative values for some of the other controls, not 
sure I want more than one knob for a control. Always, how to work 
within limits.
I suppose I could put it on a knob... mull... mull.



So what about the resolution?
96,96,96,96
This will mean that no matter how fast or slow I turn the knob the 
change in value will be the same.
If i set 24, 48, 96, 192  then it would change values faster if it 
turn the knob faster and slower if i turn the knob slower?

I have all my encoders with that, however, I might want to have say 
the lfo rate be a bit slower... 

I must study your reply to understand.
Does showvalue work for the ones below, that is +32 buttons and 
encoders?
I don't think it is working on mine.
I would hate to have to run some kind of translator for the sysex.
Although I have much experience doing cc translations.

Yes, it isn't the best solution (well it is, I guess, but not what you
want)

Yes, but it will skip values if you turn it quickly .

In one fast turn you will end up with StartValue + 192
In one slow turn you will end up with StartValue + 24
As the midi data is put out at fixed intervals there will be big gaps
in values with the fast turn.
This is great to find a value if the range is great. I have my FantomX
Bank and patch set to an encoder and a quick twist will jump banks and
slow turn to select the patch.

You can change the 'feel' of the BCR quite markedly with this thing.

.showvalue on - can be for all control elements, all buttons, all
encoders and all faders
Don't get it confused with .mode 1dot - this is for the LED ring
around the encoder.  showvalue is for the number display top right.
.mode does vary for the top row and the bottom 3 rows.

Excellent work!

I an wondering about the limitations of the BCR for what I am doing. I
would love a program that takes over the BCR with CC messages like
Reason and lets me output what ever I want.
It would allow for feedback. I would love to change a patch on the
synth and have the sysex reset all the controls on the BCR. 
Then again PCs are great for in the studio, but just an extra thing to
lug to a live gig.

The BCR's good but not perfect, but very cheap.

Royce

Alright,
Anyway to work in some logic here?
Based on what you said below,
bank and patch select, is there a way to have different commands come
out with different speed turning? I guess that would have to use some
sort of detector to figure out the speed. 
Will the BCR do and computation stuff?
OMG - I am in way over my head now!

The BCR can use 14 bit numbers in the range (minmax) and the
resolution so you can use val for the Patch and the higher bits val's
(val7.13 etc., as in your sysex) to drive the bank change.
set minmax 0 $3FFF - or what ever you want.
set resolution 43 200 600 4000 - fiddle with these number to give you
the feel you want
You can go though all patches, all banks turning slowly, but if you
turn quickly it will jump by large values and therefore banks

The BCR can put out one group of messages if turned clockwise and a
different one if turned anticlockwise

.tx ifp $B0 7 val ifn $B1 23 val

ifp = if positive = clockwise
ifn = if negative = anticlockwise

if you put a message before the ifn and ifp conditionals then it will
always be put out

.tx $B0 7 val ifn $B3 23 val

turn clockwise
$B0 7 1
$B0 7 2
$B0 7 3
$B0 7 4
$B0 7 5
turn anticlockwise
$B0 7 4   $B3 23 4
$B0 7 3   $B3 23 3
$B0 7 2   $B3 23 2
$B0 7 1   $B3 23 1

Royce,

I need a refocus.
You have sent many things to me in these responses, thanks!
I have one more request, before I slip back under my rock.
I need to do the postive/negative thing.
I will start with the pitch octave button.  
They currently increment by 1 -4...0...4.
I have two buttons how do it get the values to go negative on one of
the buttons?
Please forgive me if you already answered me.

$button 36 ;Pitch_Oct+
  .showvalue on
  .default 0
  .mode incval 1
  .minmax 0 4

$button 44 ;Pitch_Oct -
  .showvalue on
  .default 0
  .mode incval 1
  .minmax 0 4 

I don't have the sysex string yet, I am not at home.
So how do I get the negative value for the pitch oct -?
Thanks, I am almost finished, then some minor moving around of
controls and then use it!

Thanks,
Kip

Ok,
So range from -1 to -99 would be
$3FFF $3F9d
but I should write it as 
.minmax $3F9d $3FFF
Correct?

Thanks Royce.

This is for a knob.
And actually, I should change the minmax order, right?
I will try it at any rate and get back, then go back under my rock.

Hi Kip

The minmax in this case is not associated with incval, so reversing
the  numbers just reverses the direction of the encoder movement.

Use the MS calculator, select "view\scientific" .
In decimal mode type in 99  hit the +\- button then swap to hex and
you get
FFFFFFFFFFFFFF9D

just use the last 3 numbers F9D and put 3 at the start
3F9D

Royce

Royce,
I got distracted from the negative values issue, I will return...

Tonight, I discovered what the $02 was for you were wondering about.
It is a fine mess, well actually a good one.
Here goes, the vfx has, if you will, 6 voices (waves etc) to make up 1
sound or patch. 
So... that $02 is because I happened to be on 3rd voice!
Each voice has  
1. a digital osc.
2. two filters.
3. on LFO
4. three complex(6step,6level) envelop generators.
5. all the modulation routings and amounts for the above.
Up to this point, I have the 1 entire bcr patch filled with controls.
What I have here is a monster!
I am going to need 6 bcr presets, one for each voice.  Now many times
I won't need those say 4,5,6 voices... but will make the presets for
them anyway.
Wow! 

I am officially overwhelmed... by the enormity of the editing task
that lay before me.

What I need now is a way to edit the sysex string, ie a global replace
kind of thing for all the values for voice #1,2,3,4,5,6 presets
The only thing that changes for these strings going from voice#1 to
voice#2 is the $02 in the sysex string located in the 10th position.  
So, I need a way to just replace that small hex bit with $00 for the
all the values at the 10th position for the voice#1 preset.
Then go on to $01 for voice#2 preset, then $02, then $03 etc...

Do you have any wonderful ideas.
I have codeblocks installed for some other editing I was doing,
however, i don't know how to replace just the parts located with in a
hex string like this?
 
All thoughts appreciated!

I'm not sure about the usefulness of an actual search & replace
function to achieve your intended substitution: wouldn't the search &
replace function then wrongly apply to ANY value of "$02" (to use your
example)?
So what I'm thinking of is a feature by which you can replace the n-th 
item in every ".tx" line in a particular scope. I'll think about it.

Mark.

Mark, 
Yeah, what I meant was in the byte position.. or as you said the
nth...xx position yeah.

Great editor, Mark, you have opened up a vast expanse to edit this
beast with.
Thank you!

I tried to email you but it bounced back.
I was offering to add some graphics to the manual.
If you send me the doc,  I will do so then send back to you for approval.
I was a bit daunted by the program at first... a few images in the
manual might have helped, what say you?
