So far Logic X is AMAZING! :-) Before X came out, I was trying to make a talking bass in logic 9 using automation and the channel eq. Now, using smart controls I'm able to set one knob to control 3 bands of the channel eq and have each one start at the formant frequency of one vowel sound and end at the formant frequency of another. I can then assign that to the mod wheel on my keyboard for a really awesome talking effect. What I'm wondering is how the midi routing works with smart controls and track stacks. What I'd like to do is set up a midi modulator plugin to either use the LFO or the envelope filter to control my newly created talking bass smart control knob. So far, I'm not able to set up midi fx on the main track of my track stack, I have to do it on one of the synths. I tried using "learn" to assign a knob on my keyboard, then finding that midi control number and channel and setting the output of the modulator plugin to that. Unfortunately I haven't had success so far. Any help would be much appreciated!
