Hum is a Plugin that sits on a vocal channel in your Host, listens to your Voice and sends out MIDI. Any instrument you point it at plays what you sing, about 20 ms after you sing it. I made it because I wanted to play synths with my mouth at gigs and nothing I tried was fast enough to feel like an instrument.
The Host decides how big the window is. Hum decides what fits in it.
When the Host gives Hum a small window, you get the Note as you sang it, how sharp or flat you are, your level against the Gate, Octave Shift and Panic. Nothing else. It's meant to be read from a metre away with a mic in your hand.
Give it a taller window and the rest appears underneath: Smoothing, Velocity, Aftertouch, MIDI channel, Voice Through, Range. Set them once at soundcheck and go back to the small window.
Behind the Note is a waterfall of the last dozen cycles of your Voice, one period each. It's not there to be measured, it's there so you can tell at a glance whether it's hearing you, and it looks nice.
There aren't many. Each one is there because I needed it at a gig.
The Gate is the level below which Hum treats your Voice as silence. Drag it on the meter so the room and the drummer don't start notes. Smoothing is how sure Hum has to be before it changes its mind about the Note: turn it up for fewer wrong notes, down for less delay.

The Range is the lowest and highest Notes Hum will ever send, on a piano strip. Out of the box it's A2 to C6. Narrower is faster, so if you don't sing low, don't let it listen low.
Octave Shift moves every Note up or down whole octaves before it leaves. Hum a bass line without being a bass.


By default a Note's velocity comes from how loud you were when it started, shaped by the Velocity Curve. Flip to Fixed and every Note leaves at full velocity, which some instruments prefer.
Aftertouch sends your level while the Note is held, as Channel Pressure. Swell into a pad by singing louder.

Pick the MIDI channel. Voice Through is how much of your actual Voice carries on out of the Plugin, from none to all, so Hum can sit on the vocal channel without eating it. MIDI Output is the switch for whether Notes leave at all; off, it still listens and shows you the Note.
And there's Panic, on both views, because there's always one stuck note at the worst possible time.

I'd rather you knew before you paid for it.
