How to better use sample based instruments for live performance?

I am controlling sample based instruments with a midi controller during live performance. A few questions about this scenario:

  1. How would I get pitch bend to work live for sample-based instruments?
  2. How can I make a sample-based instrument monophonic? As in, only playing one note at a time like many synthesizers.
  3. How can I make a sample-based instrument ignore keyboard velocity, always playing at 0x80 volume?

Not sure if it’s possible Native, never tried to use it. If not people have done various experiments controlling the Finetune of an Instrument via MIDI, so if there’s not a Tool yet which quite does this it might only take a little hacking of an existing one…

I don’t think you can on an instrument be instrument basis. You can make all instruments monophonic by turning off Chord Mode though. I don’t know how this will make it behave if trying to play two instruments at once though (ie split or multiple keyboards.)

Doesn’t unticking Velocities in the MIDI Preferences do this?

Hmm I am thinking it might be best to just use a sampler plugin. You wouldn’t happen to have a good recommendation for Mac? Something lightweight and free? :P
