Synth Addon

Click a pad to play it — no audio files are loaded, every sound is synthesized at boot and registered with the audio engine under an alias. The canvas draws the samples the addon rendered for the last pad. Shoot and Footstep (stone) register four detuned variants each and play through playRandom, so repeats aren't identical. Room tone, Wind, and Dialogue beeps toggle seamless loops on the music channel.
