2Deck DJは、単独でも使える2デッキDJアプリです。ファイルアプリやミュージックライブラリから曲を読み込み、波形を見ながら再生、Cue、Sync、Nudge、Trim、EQ、Volumeを操作できます。 メインの使い方は、iPhoneの「Spin Me Like A Record」とBluetooth MIDIで連携するスタイルです。Spin Me Like A Recordをターンテーブルのように回して、その操作信号で2Deck DJのDeck 1 / Deck 2をコントロールできます。2Deck DJをiPad側のミキサー / デッキとして使い、iPhoneを物理的な操作面として組み合わせることで、タッチ画面だけではないDJプレイを目指しています。 ユースケース動画: https://youtu.be/1jUkZpPWr98 Spin Me Like A Record: https://apps.apple.com/us/app/spin-me-like-a-record/id6780934323 主な機能 ・Deck 1 / Deck 2 の2デッキ再生 ・波形表示、スクロール、ピンチ拡大縮小 ・Cue、Sync、Nudge、Trim、3バンドEQ、Volume ・ファイルアプリとミュージックライブラリからの曲読み込み ・プレイリスト登録 ・Bluetooth MIDIによるSpin Me Like A Record / 外部MIDIコントロール ・EP-136などのUSBオーディオ出力 ・スプリットケーブルによるL/Rデッキ振り分け ・アプリ内のカラーテーマと言語設定 外部アプリやBluetooth MIDI機器がなくても、2Deck DJ単体で音源の読み込み、波形表示、再生、Cue、Sync、EQ、音量調整を確認できます。連携時は、Spin Me Like A Recordから送られる操作信号を受けてデッキを操作します。 音源の読み込みと再生処理は端末内で行われます。

Verdict
The clearest difference is update cadence: 2Deck DJ at every 3 days against MIDITrail's every 4 months. MIDITrail's advantage is iOS requirement (12.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
