lores~ cutoff frequency inlet speed

September 9, 2011 | 11:13 pm

Does the middle (cutoff frequency) input on lores~ accept audio rate frequency changes? I’m trying to do an audio-rate oscillator controlling the cutoff and I’m not sure if it’s actually responding to the frequency changes at audio rate, or interrupt rate.

You can use a signal to control the cutoff frequency of lores~. however the cutoff frequency won’t be updated at every signal sample, but only every buffer size : the frequency will be set to the value of the first sample of the audio buffer. So if you got a 512 buffer, the freq will only be updated every 512 samples. if you really want to update the frequency of lores~ with a sample accuracy the only way is to set the audio buffer size to 1…
Be aware that controlling the lores~ cutoff freq with an oscillator (such as cycle~) can lead to instability in some cases.
note that the lores~ c code can be found in the sdk examples http://www.cycling74.com/download/MaxSDK-5.1.7.zip

Thank you Ch for a very helpful explanation!
