バンドの練習、ちゃんと残してますか? Tuttii は、メンバー全員のスマホで一斉に録音できるアプリです。 スマホ 1 台を真ん中に置いた一発撮りとちがって、 ボーカルも、ベースも、ドラムも、それぞれ近くで録れる。 あとから家でじっくりミックスし直せます。 ―― こんな経験、ありませんか? ・スマホ 1 台で録ったら、ボーカルが遠くてベースが潰れて聴こえない ・「せーの」で各自録ったら、合わせるとちょっとずつズレてる ・「さっきのフレーズ良かったよね」が再現できない Tuttii は、その全部を解決します。 ―― 使いかた 1. 誰か 1 人がアプリで部屋を作る 2. 表示された 4 桁の数字をメンバーに伝える 3. みんなが部屋に入ったら録音ボタンを押すだけ たったこれだけで、全員のスマホがピタッと同時に録音を開始します。 スマホどうしの時刻は自動でズレを補正するので、合わせる手間はゼロ。 ―― 録音が終わったら 各メンバーの音源が 1 台のスマホに集まり、ミキサー画面で: ・各メンバーの音量バランスを調整 ・左右のバランス(パン)を整える ・気に入らないトラックはミュート ・ソロ再生で 1 人ずつ聴き返す 調整した音は 1 つのファイルとして書き出して、LINE や Instagram、 AirDrop でそのままシェアできます。 ―― 特徴 ・登録不要:表示名と 4 桁の数字だけ。アカウント登録なし ・特別な機材不要:スマホとスタジオの Wi-Fi だけで動きます ・ズレない:別々のスマホで録ってもピッタリ揃います ・あとから直せる:音量バランスは何度でもやり直し ・名前付きで保存:「12月新曲テイク3」のように名前を付けて残せる ―― こんな人におすすめ ・バンド練習の音をちゃんと残したい ・MTR を持ち込むのは大げさ、けどスマホ 1 台じゃ物足りない ・新曲のアレンジを家で何度も聴き返したい ・ライブ前のリハ音源をメンバー間でシェアしたい ―― 注意 ・メンバーどうしの通信に Wi-Fi(または同じネットワーク)が必要です ・スタジオの Wi-Fi、もしくはテザリングで動きます ・録音された音はあなたの端末内にだけ保存され、サーバーには保存されません ご利用は無料です。 ご意見・要望は: tuttii@quinas.jp

Verdict
The clearest difference is in-app purchases: Tuttii at none against Stem Split's 12. Tuttii also leads on update cadence (daily vs every 8 days) and iOS requirement (12.0 vs 16.4). Stem Split's advantage is ads (none vs shown) and chart position (#179 vs unranked). On price and device support there is nothing between them.
