This is great, thank you.

I am planning a MIDI controller project to make during my last summer before college. I plan on making something similar to a keytar. I have done a lot of research but Im still not sure about a lot of things. Here is what I plan on including: - 36 arcade buttons, for hitting notes and/or activating sound effects. -USB connection. - a 4x4 matrix of buttons with LEDs underneath for selecting various control configurations. I would like to make it so I could use the instrument to select from different options stored on my computer. The matrix will act as a binary display to show me which preset I am using. -faders and knobs for volume, sustain, attack, decay, etc -small analog joysticks, for adding little flourishes or vibrato. -membrane potentiometer for pitch bend -3" illuminated arcade trackball for a tremolo effect First of all, are all of these things possible with the MIDIbox? And if they are possible, exactly what will I need in order to accomplish them? Also, should i use diodes when hooking up the buttons?
