Environment set up to "PLAY" Low-cut filter frequency

Jul 24th, 2010, 01:45

Hi, Steve, I imagine it would be fun to play (control) with keyboard the frequency of low-cut filter of the channel EQ over an audio track real time. EQ automation could be written but it's not the same... I burnt the whole evening in the environment trying to figure the transformer out. Do you have any idea how to pass midi to Ch EQ low-cut frequency, F3 parameter 1?

Hi bKrypp Welcome to the forums! A couple of questions first... Have you tried using controller assignments (Command-L) which will assign a control (like the Low-cut frequency on a Channel EQ) to a chosen knob or fader on your MIDI Controller? That would be the easiest way. Is there any reason why you want to create an Environment to do this?.. I don't mean to put you off, but would like to find out what you wish to achieve and why. btw, when building an environment, Monitor objects will be your best friends. e.g. You might choose to use a Monitor to directly see what MIDI Message your controller is sending into Logic (via the Clicks and Ports layer). :) Rounik

Hi, Rounik, Thanks for your interest. The concept is more like controlling filter cutoff with kybd in the router of ES2 than controller assignments. Micro-manipulation of lower harmonics would be quite interesting. But the channel EQ's frequency axis is logarithmic and rounding resolution is not clear, so routing the midi control to frequency parameter directly won't work...Any idea???

Hi bKrypp, OK... So you want to be able to adjust the Low-Cut freq on the Channel EQ depending on the pitch of the key you press on your MIDI Keyboard? Here's something to start you off... A simple environment that maps the cuttoff to the pitch of the key pressed on your MIDI Controller... you can easily route it to respond to velocity instead... You must have the "Low Freq Control" track selected. Is this the kind of thing you want to achieve? [url]http://www.box.net/shared/ui1tgqs20p[/url] :) Rounik
