After trying out some of the other TSIs for this controller I decided none of them had the controls I was looking for and I just found it easier to map my own from scratch. I’ve benefited from the wealth of knowledge found in these forums (and the web in general) so I thought I should add my small contribution See jpeg for all map assignment details! Things to know about this mapping… 1) Start the APC40 first then Traktor. 2) To have deck focus work correctly, at the start of your session you need to calibrate the controller which takes less than a minute. Press the Track Selection buttons 1-4 and adjust Device Controls 1-8 one at a time so they reflect 12:00. Deck focus will calibrate as you are doing this and will work now for the rest of your session. A big feature I didn’t find with any of the other TSIs. 3) Only one modifier, Shift. 4) Play has a macro with Sync. Shift + Play equals pause; this is a safety feature so you don’t accidentally stop the music. 5) Seek is actually Cue Move as this moves through the track much smoother in my opinion. 6) Device Control depends on Track Selection 1-8 and Master. 6) Track Selection 1-4 corresponds with Deck A-D. Device Control Knobs 1-4 are EQ Bands. The buttons directly below knobs 5-8 are for FX assign 1-4 on the mixer. 6) Track Selection 5-8 corresponds with FX 1-4. FX parameters 1, 2 and 3 are mapped to 1, 2 and 3. Use Device on and off to turn the FX on and off. 6) Browser and additional loop options are under the master channel. I couldn’t figure out how to have the hotcues not light up when there isn’t one mapped. Maybe somebody can help me with this. Either way there is some led feedback which helps with knowing what deck you’re on. I did my best to label everything in the jpeg attached. S+ means with shift. Let me know if you have any questions and please let me know what you think. Be constructive please as this is only version 1.0! I hope you enjoy!
