Hi, 
 
I have a mixing desk that needs moving fader automation. Well, its a Calrec S2 60-channel console equipped with Alps 10K ohm non-motorized faders.  The (long-term) goal is to build an automation system for it to control: 
 
- 60 channel faders (30 mono, 30 stereo) 
- 8 group faders 
- 2 main out faders 
 
Hence, I am basically interested in controlling the desk via Midi from Logic and Pro Tools, not controlling this software although it might be a nice feature for some task.  What is the best approach for this project in terms of MB hardware? I would like to stay with a minimum of hardware components but, naturally, still have professional performance (timing) during mixdown. Do I need a core card (if so, 8 or 32?) or can I daisy chain 8 motor fader cards and rewrite the software on each PIC so they respond to one Midi channel (with a SysEx tweak)? 
 
...and big thanks to all amazing contributors, especially TK.
