How to play

To play the synth you can:

How to create sounds

You can create custom synth sounds by messing around with the synth knobs:

• Customize the waveforms, pitch detune, and amplitude of each oscillator.
• Adjust the volume envelope of the master output.
• Filter low or high frequencies with the low-pass and high-pass filters.
• Destroy the sound with digital distortion.
• Add volume with convolution reverb.

How to be Daft Punk!

Here's how to use the vocoder and be awesome:

• Enable by vocoder by toggling the on/off switch.
• Allow the synth to access microphone.
• Play the keys (you won't hear anything).
• Sing into your mic (OMG it's autotune in the browser!!!).
