Reducing only high notes in a monophonic part

[Booli]

Hi
I have a monophonic synth bass part, using arpeggio, which generates lots of low notes, and few high notes.
I like the high notes, they make the part groovy and interesting,
However I'd like to attenuate them. Make their gain a little lower (e.g. -6db).

Using MCharacter, or another Melda,
Is this function achievable?
I can really use a hint.

Thanks!
Booli.

This is probably best done in the synth if you can. Link the keyboard tracking to the volume, so the notes get quieter as they increase in pitch.

If that is not an option and you only have an audio sample to work with, then. maybe you could use a modulator in pitch mode to modulate volume so that it is quieter for higher pitch.

Or you could try dynamic EQ?

You could attach midi to a volume control (e.g. in MUtility if that has modulators, I don't remember; or just any other plugin). Probably it's best to take the detour via multiparameter so you can introduce some smoothing/inertia, so that it doesn't react too abruptly. Let a multiparam control some volume, and attach midi to that multiparameter.

Non-Melda solution: Use the DAW "audio to MIDI" function (such as in Cubase VariAudio), adjust the velocity there. I guess you'd have to send it back to the synth and then again back to the DAW. So maybe just easier to automate ...

Thanks for the ideas:
The key tracking modulation indeed solved that perfectly.

however for the sake of curiosity I tried few more ideas:

- modulate pitch - although monophonic, I couldn't achieve a fine configuration which will be smooth enough and transparent. the result was jumpy and inconsistent.

- AutoDynamicEQ - do the job. not perfect like the synth inner tracking, but better than nothing.

MCharacter - I'm pretty sure this tool design for this kind of task, however have no clue where to start from....

Use a multiband compressor. Compress the high end, but leave the lower bands alone. Mmultiband dynamics can do this. If you can change it in the synth using key tracking that is the best solution, but if not try multiband compression.
