You are nearly there but there are some manual steps required since you are using a generic codec for APC64 and the controller must be "locked" to the Reason Big Mixer master section so the auto mapping can apply.
1. Open remote map file (MIDI Keyboard w Controls.remotemap) for the generic keyboard remote codec. On Windows it´s somewhere here C:\Program Files\Propellerhead\Reason 13\Remote\DefaultMaps\Other\MIDI Keyboard w Controls.remotemap in a text editor, search for "Reason Master Section". There, you see that the channel level entries are commented out.
This is because the generic codec does not know about any controller specific MIDI CCs so you have to set them manually.
Code: Select all
//< 20110628
Scope Propellerheads Reason Master Section
// Control Surface Item Key Remotable Item Scale Mode
Map CC 07 Master Level
Map CC 12 Threshold
Map CC 13 Attack
Map CC 14 Release
Map CC 16 Ratio
Map CC 18 Make-Up Gain
//Map CC ?? Channel 1 Level
//Map CC ?? Channel 2 Level
//Map CC ?? Channel 3 Level
//Map CC ?? Channel 4 Level
//Map CC ?? Channel 5 Level
//Map CC ?? Channel 6 Level
//Map CC ?? Channel 7 Level
//Map CC ?? Channel 8 Level
Remove the // from channel level entries and replace the ?? by your specific CCs in decimals (0 - 127) of the APC64
and save the file
2. Restart Reason, add some mix channels and lock the MIDI keyboard control surface to the master section (right click on master section -> Context Menu -> Lock ....
I think the lock is saved with the Reason document so it keeps the lock assignment per document.

Hello and sorry for my bad English. As the title says, I'm struggling to understand how MIDI works in Reason. I don't care if the Play/Stop/Rec functions don't work. I'm only mapping the 8 faders to CC16 and onwards in the APC project manager. I save the settings, enable MIDI send from everywhere, set the APC to standalone mode, and in Custom settings, I'm sending MIDI from everywhere
When I look at the fader map in the controller, everything is set up correctly: faders are mapped from CC16 to CC23.
In Reason's MIDI preferences, I've chosen a generic MIDI keyboard. It recognizes the APC as a controller and receives MIDI data from the faders. I've tried the sync option, selecting the APC, but nothing seems to work. I have to manually map the faders with an override action.
Can someone help me or at least tell me if this "auto map" is not possible at all?
Thank you in advance!
