Piano Synthesizer Component

Owner: Zane Aridi

Functionality

Piano class dervived from tone instrument handles the playing of the instrument
PianoAR is the envelope for the piano and has a default release that’s about as long as a piano’s
Each note has an xml pedal pressed option which increases the sustain of the note by extending duration and release
The amplitude of notes varies based on the speed attribute specified in the xml that mimicks the speed at which a key is pressed (providing dynamics). In addition, the attack of the piano note envelope is shortened with higher press speeds to provide advanced dynamics.
The pedal noise should be generated by a sample at the beggining of a notes generation, however I commented it out because for some reason I get Link error 2019 for an unresloved external symbol. I created a resource for it and used the resource ID, but I couldn’t figure out why I can’t find the wav file. I would very much appreciate partial credit <3.
