The signal path is: oscillator → <code>gain &#42; velocity</code> → filters → distortion → modulation → phaser/flanger → <code>envelope &#42; postgain</code> → chorus → <code>pan</code>.

<CommandEntry name="gain" type="number" min={0} default={1}>

Pre-filter gain multiplier. Applied before filters and distortion, combined with <code>velocity</code> as <code>gain &#42; velocity</code>.

<CodeEditor code={`/sound/saw/gain/0.2`} rows={2} />

</CommandEntry>

<CommandEntry name="postgain" type="number" min={0} default={1}>

Post-effects gain multiplier. Applied after phaser/flanger, combined with the envelope as <code>envelope &#42; postgain</code>.

<CodeEditor code={`/sound/saw/postgain/0.2\n\n/sound/saw/postgain/1/time/0.25`} rows={4} />

</CommandEntry>

<CommandEntry name="velocity" type="number" min={0} max={1} default={1}>

Multiplied with <code>gain</code> before filters. Also passed as <code>accent</code> to Plaits engines.

<CodeEditor code={`/sound/saw/velocity/0.2\n\n/sound/saw/velocity/1/time/0.25`} rows={4} />

</CommandEntry>

<CommandEntry name="pan" type="number" min={0} max={1} default={0.5}>

Stereo position using constant-power panning: <code>left = cos(pan &#42; π/2)</code>, <code>right = sin(pan &#42; π/2)</code>. 0 = left, 0.5 = center, 1 = right.

<CodeEditor code={`/pan/0/freq/329\n\n/pan/1/freq/331`} rows={4} />
