I have need for this as well and it feels odd to have to re-implement an AudioParam's facilities given that it is sitting right there. However, if you're desperate enough, there *is* an inefficient/ugly/kludgy way to read an AudioParam into a JS node - signal with dc level 1 => GainNode => ChannelMerger => JSAudioNode The AudioParam in the GainNode then becomes available as a signal you can use within JSAudioNode. This way, you can access the parameter at a-rate irrespective of whether it is set at a-rate or k-rate. The dc signal can be generated using - Oscillator => WaveShaper(clamped at 1) :) -Kumar anclab.org
