This is a sequencer that wants to work like a DJ's turntable rig. 
Or whatever they call those. 

The idea is, when you watch a DJ working, they have one thing playing, for everyone, 
and another thing playing into their headphones, that only they can hear, 
until they mix it in. 
        
Here, the work area is on the left, where you can change stuff. It plays on the left channel. 
The right side is the what's-playing area; you hear it on the right. 
In a performance, you'd only let everyone hear the right-hand side.  

The interface is organized by rows. 

The rows with the "+---+---"'s are decorative and don't do anything, mostly. 

Each other row is a sequencer. Letters a-z correspond to different samples. 
Twirly shows what letter is what sample. 

But hey, you can only make changes on the left!
You can't even move the cursor to the right side!

The far-left column is the countdown timers.
Make (secret) changes on the left, set the timer, and it counts down. 
When it gets to 0, the row is copied over to the left; then everybody hears it. 

There are 9 sequencer rows: three sets of 3
There are 16 sample slots for each sequencer row, under the "+---"'s. 
The column after the last sequencer slot is the mixer; it sets the row's relative volume.
The columns after that are gain, filter low, and filter high.

The second column from the left is the fade timer; once the countdown goes to 0, 
the fade timer moves the value on the right to the value on the left in however many measures. 

Both timers count only in measures. It's EDM, kid; it's all measures. 
People say they love polyrhythms and then you play them one and they're all, "wut?"
Four-on-the-floor, man. Give the ppl the wut they want.

The top row lets you set beats/min, reverb, and filter for all rows. 
Oo look, there's a metronome "+" thingie sweeping around. Heh!

All non-seqencer values use "Orca" digits: 0-z, where 0 is 0, 
9 is 9, a is 10, h is 18, and z is 36, as a compliment to Orca.

The bottom row is the "break" row. When its timer goes to 0, 
all other rows are silenced for one measure, and only the break plays.
But then in the next measure, everything pops back to how it was. 
The second-from bottom row is the "live" row. 
Whatever you do there gets copied right immediately. 
If you wanna play with fire like that. 

Are those Daft Punk references yes of course they are.
