Prophet 5

This is an emulation of the analog Prophet-5 in Max. For the interface, I followed the original layout. It's satisfying to watch the knobs and buttons connected to the patcher float into place in the presentation view.

The two additional features I added are:
1, Four filter modes (low-pass filter, high-pass filter, band-pass filter, notch filter, etc.) 
2, Use velocity as a modulation source of filter cutoff. The amount of modulation is controlled using the "Env Ctl" knob.

In the demo video, I demonstrated the various functions incorporated into the synth using a midi keyboard.
