synthesizer

This is a bare-bones monophonic MIDI synthesizer that uses the pitch and velocity information from incoming MIDI note messages to control the frequency and amplitude of a sawtooth waveform. 

This patch uses the MIDI key number (pitch) data byte to set the frequency of a sawtooth oscillator, and it uses the velocity data byte to set the amplitude of the oscillator. Note-on velocity values in the range 1-127 are mapped to a range of decibels from -60 to 0, and those decibel values are then converted to linear amplitude values to scale the amplitude of the oscillator.

This is a bare-bones monophonic MIDI synthesizer that uses the pitch and velocity information from incoming MIDI note messages to control the frequency and amplitude of a sawtooth waveform. It works, but it could definitely be improved. It's nearly identical to the even more bare-bones "Overly simple MIDI synth" example, but with one improvement, the addition of the poly object, described below.
