6. Making a volume slider

-

1 “If we set our Resolution and Ratio to really low numbers, we’re going to get really loud audio; so to protect your speakers and your hearing, we’re going to stick in a little volume fader to pull down the gain. This is going to sit in between the plugout and the degrade~.” 2 “The type of control we’ll use is another live. object, so press N for New, type in ‘live.’, and the object we need is live.gain~ – a decibel volume slider. Patch it into the signal path by recabling left and right outputs of the degrade~ into the live.gain~ inputs, and take the signal path from live.gain to the plugout object.” 3 “In the Inspector, we can customise slider properties. At the top, there’s one called Orientatio­n: set it to Horizontal. It’s got the default name of ‘live.gain’: double-click and call it Output Gain, then copy that into the Long Name field. Switch on Initial Enable and pull down the Initial Value to -12., for a value of -12dB when we first load the patch.” 4 “This is a good place to save our device. Make sure it’s selected, jump to the Max File menu – not the Live File menu – and select Save As. Save the device in the default location, the Max Audio Effect folder, and give it a sexier name: The Degrader. Congratula­tions – you’ve built a device, patched in everything you need and saved it!”
