Default Overtone EQ

This is my first attempt at a JS FX, it's based on Scott Stillwell's RBJ Cookbook EQ.

It's a dynamic EQ that takes a midi note input and calculates the note frequency and harmonic overtones then adjusts each EQ bands frequency accordingly.

It is best used more as a sound shaping tool than a normal eq and works well on monophonic lines, although it can also work on polyphonic lines when just fed the bass notes.

3 ways to use this plugin:

1. Inserted after a VST instrument (one that allows midi to pass through to the chain) as a sound shaper - try boosting the 1st & 2nd harmonic for more presence.

2. On an audio track with a midi recieve from a separate track, the midi track could be an exact copy of the audio (ie, copy a midi file to the next track before rendering then send the midi back to the original track) or you can send bass notes for a chord track.

3. On an audio track with Reatune first, sending midi to the chain - this works ok on slower lead lines but can produce some eratic results.

I've added a project file so you can see it working on a ReaSynth plugin.

Pretty impressive. I just loaded an mp3 track, and put it on, and wow really polished up the treble nicely.

Thanks, glad you liked it, hopefully I'll get round to developing it futher since there are some funny sounds where the notes are far apart and the plugin doesn't adjust in time. Also, might add some presets for different instruments.

Thanks, your project looks really good - I've not looked at JS much since I made this plugin - and I'm not sure I can remember how I did this :-).

You're welcome to reuse any part of it (including credit to Scott Stillwell) - if there's a good JS frequency detector somewhere it could probably be modified to work with this instead of using a pitch to midi convertor to feed it midi.
