DJMAX RESPECT V

This is *almost* the hardest achievement in the game, second only to the ones that require unlocking LINK DISC but only due to how clearing all of these missions is a requirement for those too.

Technical Mixing is the 2nd group of Technika 1 missions. Each of the 6 missions have their final song in the style of the Technika arcade gameplay (categorized as "TB") where notes scroll across two horizontal halves of the screen. These songs will be listed as "??" or "?!" due to how the song will change depending on what your current combo is at the end of the song before it. If your combo is an odd number you'll load the 1st song, and if your combo is even you'll load the 2nd. The exception to this is the final mission, 'Conqueror', which has a 3rd song that will appear randomly instead of the other two. To unlock this achievement you need to have at least started playing all 13 possible TB patterns.

Here is a list of the patterns you'll need to play. Keep in mind you don't actually need to clear these songs, once they've loaded and you've let it play for a little bit, you can just quit back to the Mission Select menu and move on to the the next one. You do however need to clear all of these missions anyway for 2 of the LINK DISC achievements, so I'd only recommend quitting out if you've already completed that mission before.

First Step (2-1)

• Odd - Only for you
• Even - I want You

Electro EP (2-2)

• Odd - SuperSonic
• Even - Electronics

Futurist (2-3)

• Odd - Don't Die
• Even - Mulch

HeartBeat (2-4)

• Odd - The Clear Blue Sky
• Even - BlythE

Customizer (2-5)

• Odd - SIN
• Even - SON OF SUN

Conqueror (2-6)

• Odd - HEXAD
• Even - NB RANGER - Virgin Force
• Random - Thor

While the grind of completing these missions multiple times is part of what makes this achievement hard, the main reason is due to the sheer difficulty of those last few missions. Here is a video of the 'Conqueror' mission by ValenBoA, who gets an even combo and plays 'NB RANGER - Virgin Force' as their final song.
Needless to say this mission is absurdly hard, and probably the biggest roadblock for most players looking to complete all of the achievements. Aside from practicing a lot of hard 8B songs there's not too much you can do to make this easier. The first song is the SC pattern of 'Landscape' and almost definitely not possible to complete using a controller, so learning how to play the game on keyboard is basically a must.

If you're not already good enough to be clearing 8B SC patterns with less than 10 breaks each, I'd leave this to be one of the last achievements you decide to go for and hope that by the time you've unlocked almost all of the others, you've improved enough to at least have a chance with this one.
