Hello,
I have successfully adapted the Crumar DU9 drawbar controller to the Astrolab so that it controls the foot positions of the B3V.
However, it works in reverse. At maximum setting, the astrolab goes to minimum and vice versa. I reversed the values in Analoglab, unfortunately this did not affect the function in Astrolab.
I think this is a bug or did I miss something?
I also didn’t find a function for transferring midi controller setups to the Astrolab.
Does anyone have an idea about this?
Hi @Hufe ,
I don’t have Astrolab.
Do you mean the Foot pedal drawbars? How exactly have you done this?
Where and how did you reverse?
Keep in mind, that Analog Lab is an application of it’s own. It has it’s own global midi configs. It’s not pr preset.
What have you done in Astrolab? And how?
Astrolab is already mapped to relevant controls.
Faders can be set to reverse functionality. Can’t you drawbards be set to work in reverse? It sound like it work like faders soo oulling out the drawbar is the same as moving a fader down.
Hope this can help.
Hello Hufe,
interesting, I was looking at the D9U for that purpose, but haven’t had a chance to try it.
Are you using the default configuration (made for Mojo) or are you able to reprogram its CCs using Arduino-based sktech editing?
AstroLab only has one default MIDI CC mapping. Editing MIDI mappings in Analog Lab doesn’t affect AstroLab.
I’m using other external MIDI/USB faders that match the default mapping of AstroLab:
- Fader 1: 73
- Fader 2: 75
- Fader 3: 79
- Fader 4: 72
- Fader 5: 80
- Fader 6: 81
- Fader 7: 82
- Fader 8: 83
- Fader 9: 85
And they behave automatically in “Drawbar mode” (i.e. drawbar at 0 when fader is all the way up, drawbar at full when fader is all the way down) on B3V and Vox V presets.
This is reversed from all other instruments where faders behave “normally” (0 all the way down, 127 all the way up).
(note: using the Brigthness Macro affects the values of the drawbars for B3V presets)
So, I’m guessing that the default D9U settings are already reversed from factory, so when used with B3V, reversed+reversed goes back to “Fader mode”.
I think that this can be changed in the D9U, but as noted in the D9U documentation:
" Compatible with many clonewheel organs or synthesizers (might require some skills with Arduino)"
Hello and thank you for the answer!
Now it’s clear:
with the Astrolab, the MIDI CC assignment for drawbars is fixed. This means that a self-created MIDI setup cannot be transferred from Analoglab to Astrolab.
With Crumar, etc., the drawbars for the upper manual are at CC 12, 13, 14,… I can easily change this in the Arduino script to the CC numbers for the drawbars in Astrolab.
But I can’t change the value inversion there because I don’t know how.
Maybe I can find someone who can program it. I would then post the script for the DU9 drawbar controller here.
Cheers
