[linux-audio-dev] Interesting USB MIDI master keyboards, do they work with Linux ?

I meant of sending midi events from the master keyboard via USB to the PC
 which runs an internal soft-synth/sampler. 
In that case USB should improve timing because of the bigger bandwidth,
(but will add 1msec of latency due to USB1 polling mechanism as far as I can
Correct me if I'm wrong.

Not really, unless you are spreading those chords on several separate midi 
outputs. If it just one, then it determines the bandwidth available. 
Getting things faster to the interface will do nothing because it still 
has to send the bytes to the external synth at the same old slow 31250 
baud speed.
