Hello all, I was curious for more information as to how the MIDI functionality worked on surferEQ. I am very fascinated by an EQ that changes with the pitch of something, and it seems like it would be invaluable for bass. My main concern is that I don’t trust the pitch tracking. I was wondering if it was possible to copy/paste the MIDI from my bassline and have surferEQ read that and apply it instead of pitch tracking?
Thanks for your time!
Hi @nuclearrabbit17!
First, try our pitch tracking out 
it’s pretty sophisticated.
Usually it works great out of the box but can be adjust with Pitch Tolerance and Threshold to handle noisy/tricky signal.
SurferEQ2 got many MIDI workflows. for farther details check the SurferEQ Manual here:
https://www.soundradix.com/products/surfer-eq/
Quoted from the manual:
- MIDI Mode 1 : Note Overrides Detection
Designed for easy correction of the pitch-detection engine when required. A MIDI Note On input will
override the internal pitch-detector. On MIDI Note Off, the pitch-detection engine will resume its
operation.- MIDI Mode 2 : Surf by Note
Designed for frequency-specific ducking. Pitch/frequency is controlled by MIDI and the internal
pitch-detection engine is disabled. MIDI Note On/Off toggles Surf-enabled bands.- MIDI Mode 3 : Instrument Mode
Designed to be played like an instrument where the source audio acts as an oscillator.
Pitch/frequency and sound are controlled and triggered by MIDI Notes
So you can get complete MIDI based control or just “help” SurferEQ if needed.
TL;DR: yes, you can use midi instead of detection 
(you’d might also want to set it to LIVE mode to reduce latency used for better pitch-tracking).
