this may or may not be a dumb question but here goes. i am using the mbox with pro tools 4. i want to buy either a usb midi keyboard or an actual midi interface. that would be my first question. what do you all recommend for the setup i am using? I am running on a Powerbook G4. 1 ghz. 512 ram. what i want to do eventually is to use a sampler such as NI kontakt or NI battery or other drum samplers and have it so i can set up a whole drum kit in the sampler software and be able to trigger each drum (snare, kick etc...) sample by hitting the corresponding key or pad on my midi keyboard. is that how it works? is there a way to load up a whole classic piano so you literally turn your midi keyboard into a piano? or organ? etc... i also use a Boss Dr. Rhythm DR-670 drum machine which has midi ins/outs. can i use that with drum sampler software? could i program certain kicks and snares etc... from sample cds so that they can be triggered using the drum machine pads? i would appreciate any help on on this. i've wanted to get into midi and triggers for a while now but before i spend money on some equipment i want to make sure i understand how it all works. thanks in advance. looking forward to hearing some responses. cheers.
