A_Star_Sequencer

An implementation of A* path planning algorithm purposed as a step sequencer used to trigger music events in maxMSP.

This project was made infinitely more approachable with the helpful documentation provided by Pawel Janicki which elaborates on how to integrate p5.js with maxMSP. Additionally, Daniel Shiffman's tutorial on implementing A* in p5.js was a truly wonderful resource to be able to reference.

Functionality

NOTE: The intended functionality of in/out messages is listed below but once the message is received into maxMSP the user can purpose the messages differently if they choose.

Input Messages	Description
'set_stroke_color'	Takes 3 arguments representing RGB values between 0-255 that set the stroke or 'outline' color of the 3D grid.
'set_background_color'	Takes 3 arguments representing RGB values between 0-255 that set the background color of the 3D space.

Output Messages	Description
'soundN' where N = [0,7]	Outputs message to trigger sound listeners. (example: 'sound5')
'pitch_down_quarter'	Decreases pitch by 25%.
'pitch_down_half'	Decreases pitch by 50%.
'no_pitch'	Sets to original pitch.
'pitch_up_half'	Increases pitch by 50%.
'pitch_down_quarter'	Increases pitch by 25%.

Mouse and Keyboard Interactivity

Actions	Description
Mouse press + drag	Rotates the perspective of A* grid.
Mouse press right side of screen	Increases frame rate & tempo by a factor of 10.
Mouse press left side of screen	Increases frame rate & tempo by a factor of 5.
Mouse press quadrant 1	Outputs pitch change message. Mouse release outputs 'no_pitch' message.
Mouse press quadrant 2	Outputs pitch change message. Mouse release outputs 'no_pitch' message.
Mouse press quadrant 3	Outputs pitch change message. Mouse release outputs 'no_pitch' message.
Mouse press quadrant 4	Outputs pitch change message. Mouse release outputs 'no_pitch' message.
