hmowday Posted June 7, 2017 Share Posted June 7, 2017 Hi all, I have a project wherein which I'm trying to modulate a MIDI ((CC) parameter from an audio source. Audio playing on one track,...depending (for example) on its frequency, that audio track then modulates a Cutoff Frequency of a Synth. I believe this is called MIDI-Side chaining. I know how to side chain, but not sure of a native LOGIC technique where I can extract midi data from an audio track. The application I wish to use this for is not appropriate for the Audio to Midi technique. I'm after Control Data. I believe Blue Cat Audio have a DP Meter Pro which CAN do this. For $99 its probably worth it, but was wondering if anyone out here knew of a Logic Only technique. Regards and Thanks, Hylton Quote Link to comment Share on other sites More sharing options...

Ah. So you're not trying to modulate but to create MIDI CC events based on specific parameters from the audio source. I believe this is called MIDI-Side chaining. It isn't, and it's not related to sidechaining in any way. In the example you describe, what you're looking for is a tool that does Frequency-tracking, or Pitch-tracking, and can generate MIDI notes as a result. The problem is, audio doesn't have ONE frequency, just like an image doesn't have ONE color. So... I'm still not clear on what it is exactly that you want to do.

hmowday Posted June 8, 2017 Author Share Posted June 8, 2017 Thats kinda what I'm after. I realise audio is not just one,...but for example one could say any frequency <12Khz could affect a cutoff for an oscillator whilst frequency between 5K and 8K could affect an LFO. I think Blue Cat does this (checking out demo now)....just wondering whether Logic X can do this with its own set of plugins. Quote Link to comment Share on other sites More sharing options...
Multiman2 Posted June 8, 2017 Share Posted June 8, 2017 The ES2 and the EXS24 can use a side chain as a modulation source (envelope following). You can get some nice effects having an audio track affect various parameters - pitch filter cutoff etc.. Its not exactly what you want but its a start.

hmowday Posted June 8, 2017 Author Share Posted June 8, 2017 Thanks Guys,....Yes I'm doing that now and it works well, however I'm after MIDI. I think I'll just purchase the Blue Cat stuff. It does it exactly. Quote Link to comment Share on other sites More sharing options...
