An alternative to using automation...

[josefreak]

I've got L12 and I'm looking to automate a filter sweep for a specific device on a midi track. I know that I can enable automation, link it to a knob, and create peaks and valleys to randomize the knob settings, but I don't think it's very efficient, and it's a bit tedious (I want it to happen throughout the whole song). Does anyone know how I can do this via a midi tools or another way other than using automation? I basically have a snare hit every quarter note, and I want to randomly modify a filter between a range on every hit so that the sound changes a little each time. Is there a way to do this?

So much depends on how you want the filter to change the sound and a deep dive into Roar which has some robust tempo synced modulations as well as envelop follower that creates a signal from the audio itself, just might get you closer to what you want than a very old school trick I'm about to suggest.

Place an Auto filter on the track with the snare. You can have the auto filter automatically change the frequency of the filter by adjusting the LFO which can be temp synced or just drift along at rate you specify. Adjusting the shape of the LFO will also effect the sound. If the snare is on the 1/4 note, set the temp to 1/32 and set the shape to random for a slightly glitchy effect (I have no idea what words to use to describe the effect)

The Expression Control device can do this. Find the 'random' header, map it to your preferred parameters, set limits/curves accordingly. Every time a note plays, a different value is sent.
A powerful device...
The LFO modulator device with some jitter or in Stray mode might be another option.

Thank you for the suggestions. I love Roar but have only used it for basic saturation. I'll play around with it some more. I did however get something close to what I wanted with Auto Filter. Thanks, again!

Thanks for the tip. I'm always looking for different ways to avoid track automation
