Transport and fader control in cubasis

Hi jakersjaw and fitz,

I got waylaid yesterday, but found a little bit of time to make some progress on this and have a set of rules that I hope will work with the nektar lx. There's a little bit more gymnastics to do, but I'll lay out what to do step by step.

First, in preparation, I would strongly suggest deleting and re-installing MidiBridge from the App Store. That way nothing we messed around previously will interfere and some assumptions I have made about certain settings will apply. There are 4 sets of rules and 3 scenes so they have to be deployed carefully.

1. With your virgin MidiBridge, connect the lx keyboard and connect the keyboard port on left to MidiBridge on right (as before). NB we do not need to mess around with network/localhost with this anymore.

2. Open up the Stream Byter on the MidiBridge output port (the one on the right that has a green line going to it) and paste in the following:

# HuiBox remote canonical processor
# for MidiBridge Stream Byter
# by audeonic Aug 2015
# install on output port only (RHS)

# block all ctl except canonical events
B0-B = XX +B # block chans 1 to 12
BC-E 08-7F = XX +B # block unused ch 13 - 15
BF 08-40 = XX +B # block unused ch 16
BF 48-7F = XX +B # block unused ch 16

# send ping on ctl (clone)
BX = 90 00 7F +C

# transport
BF 41-45 7F = B0 0F 0E +D50 +C
BF 41-45 7F = B0 2F X2 +D50 +C

# track mute/solo/rec
BC-E XX 7F = B0 0F X2 +D50 +C # select zone
BC 00-07 7F = B0 2F 47 +D50 +C # rec
BD 00-07 7F = B0 2F 43 +D50 +C # solo
BE 00-07 7F = B0 2F 42 +D50 +C # mute

# group L/R
BF 46-47 7F = B0 0F 0A +D50 +C
BF 46 7F = B0 2F 41 +D50 +C
BF 47 7F = B0 2F 43 +D50 +C

# faders common
BF 00-07 = B0 0F X2 +D50 +C
BF 00-07 = B0 2F 40 +D50 +C
BF 00-07 = B0 X2 +D50 +C

# faders specific
BF 00 = B0 20 00 +D50 +C
BF 01 = B0 21 00 +D50 +C
BF 02 = B0 22 00 +D50 +C
BF 03 = B0 23 00 +D50 +C
BF 04 = B0 24 00 +D50 +C
BF 05 = B0 25 00 +D50 +C
BF 06 = B0 26 00 +D50 +C
BF 07 = B0 27 00 +D50 +C

# block all original events
XX = XX +B

3. Press 'Install Rules', then 'Done' and 'Done'. Now install the following rules into the Stream Byter on the keyboard input port (on left with green line coming from it)

# map Impact LX controller to HuiBox
# by audeonic Aug 2015
# scene 000 - main

# transport
BF 67 = BF 41 # <<
BF 68 = BF 42 # >>
BF 69 = BF 43 # []
BF 6A = BF 44 # >
BF 6B = BF 45 # O

# faders 1-8
BF 0C = BF 00
BF 0D = BF 01
BF 0E = BF 02
BF 0F = BF 03
BF 10 = BF 04
BF 11 = BF 05
BF 12 = BF 06
BF 13 = BF 07

# buttons 1-8 (mute)
BF 15 = B0 00
BF 16 = B0 01
BF 17 = B0 02
BF 18 = B0 03
BF 19 = B0 04
BF 1A = B0 05
BF 1B = B0 06
BF 1C = B0 07

# hold for rec (CC 0-7) or mute if not held
B0 00-07 = CF 00 +H1000 # revert timeout
B0 00-07 7F = CF 02 +C # switch hold scene
B0 00-07 00 = BC XX 7F # up -> rec
CF = XX +B # block internal PC

# but9 - select shift scene
BF 1D 7F = CF 01 +C

4. Press 'Install Rules', Done and Done and open up the 'Scenes' panel. Hold your finger down on slot 000 until it prompts you to save. Name the scene 'main' and press 'Save'

5. Paste the following rules into the lx (left) Stream Byter, replacing the previous ones:

# map impact 61 controller to HuiBox
# by audeonic Aug 2015
# scene 001 - shift

# renumber track buttons
BF 15 = B0 00
BF 16 = B0 01
BF 17 = B0 02
BF 18 = B0 03
BF 19 = B0 04
BF 1A = B0 05
BF 1B = B0 06
BF 1C = B0 07

B0 00-07 = BD # track solo (CC 0-7 off)
BF 1D 00 = CF 00 +C # shift (but 9) - select main scene
CF = XX +B # block internal CC

6. Press 'Install Rules', Done and Done and open up the 'Scenes' panel. Hold your finger down on slot 001 until it prompts you to save. Name the scene 'shift' and press 'Save'

7. Paste the following rules into the lx (left) Stream Byter, replacing the previous ones:

# map impact lx controller to HuiBox
# by audeonic Aug 2015
# scene 002 - hold

# renumber track buttons
BF 15 = B0 00
BF 16 = B0 01
BF 17 = B0 02
BF 18 = B0 03
BF 19 = B0 04
BF 1A = B0 05
BF 1B = B0 06
BF 1C = B0 07

B0 00-07 00 = CF 00 +C # hold cancel
B0 00-07 00 = BE XX 7F # up -> mute
CF = XX +B # block internal PC

8. Press 'Install Rules', Done and Done and open up the 'Scenes' panel. Hold your finger down on slot 002 until it prompts you to save. Name the scene 'hold' and press 'Save'

9. In the Scenes panel press 'Load' button for slot 000. In MidiBridge Preferences, Options tab set Scene Channel to 16 (important)

10. Switch to Auria and ensure that 'Receive/Send Remote' is highlighted for MidiBridge. Receive/Send Clock is not required.

That's it. I obviously don't have an LX keyboard so I cannot test this (I tested on oxygen keyboard) but this is what this will give you:

- full control of Auria transport (<<, >>, >, [ ] and o )
- 8 lx faders control 1st 8 faders in Auria
- 1st lx buttons set mute by quick press/release, track rec by long press/release (> 1 second) and if you press any of the 8 buttons while holding down the 9th button (shift) then you can set solo.

The one extra bit I have working with my keyboard which I don't for the lx is the ability to move the fader/track buttons to control the next/previous set of 8. This what I thought I could use the octave buttons for. I could map two of those pads to move group left/right if you tell me which notes they generate.

Anyway, this is a very long post. I would like to make this available more generally and promote to Auria or HUI capable DAW users once I know it works for the LX. I will probably create a new thread introducing 'HuiBox' with instructions how to 'roll your own' HUI control with just about any standard MIDI controller.

Let me know how you get on!

Regards, Nic.

Ok. A hard reset did the trick. But, mute/sole and arm track still doesn't work. And rewind screws it all up. Another thing is,l the faders in auria immediately adjusts to where the faders are on the lx. So if I've mixed a project and want to work on it again, it changes to however the physical faders are on load up. But one thing at a time

Hi jakersjaw,

If you repeat steps 3 to 6 (I have updated the rules) that might help. I have updated the rules in the post. That will at least remove the conflict. If the buttons don't trigger mute then I got something wrong, but I am relying on yourself and fitz to debug remotely for me!

Regards, Nic.

Yes the 8 faders work. Will give you the cc's tonight.

Maybe fitz should try it out too. To make sure it's not a mistake on my end.

Sorry, I'me been busy with kids (3!) and summer holidays. Will have time tomorrow and will get back to you asap.
Yes, and also my admiration and gratitude for the enormous amount of work you've done Nic.

Ok,
Record, start, stop, rewind and fast forward all worked fine (once I chose HUI instead of MCU in the Mackie section).
No loop/cycle yet
I couldn't get any of the faders to move.
Mute and enable record seemed to happen whether I short pressed or long pressed.
These are not all on the right buttons. Eg button 1 worked, but button 2 operated track 3. I can go through the list if necessary, but it seems to follow that list I gave earlier.
Mute seems to work on every 4th press (ish - haven't tested this properly), but sometimes started rec enable at the same time, especially on the first track.

I tried the hard reset without change.
I also deleted MidiBridge a second time and followed all the instruction again,with the same results.
It's worth noting that the Lx has another port which is apparently used for DAW integration, but which doesn't seem to be accessible to MidiBridge. It sees it but doesn't receive any info from it. This maybe where the cc from octave up and down are?
Also all the presets are editable. If you want the faders and buttons to follow the sequence 0,1,2,3 etc this is easy to do. Will try that a bit later.
