The original concept was driving the GUI interface entirely from a MIDI keyboard, as you could pretty much guarantee they might be available. The keys where mapped so the select or back,or its nearest equivalent sat under the thumbs . . .

zynthian-ceed.local is on MIDI Channel 3

So we have:  
Control 115 \<\< 127 on each press Rewind  
Control 116 \>\> 127 on each press Fast Forward  
Control 117 [] 127 on each Press Stop (red Square)  
Control 118 \> 127 on each press Play  
Control 120 @ alternates 0 (Not Lit) ,127(Lit) Loop  
Control 119 O alternates 0 (Not Lit), 127 ( Lit) Record.
