2017.6.27に、Studio One Version 3.5.1がリリースされました。
バーチャルインストゥルメントのレイテンシやCPU負荷のあたりをさらに改善（修正？）した様子。
Tape 64bit対応。なお、64bitとはオーディオエンジンのことなので、アプリが64/32ビットかどうかは関係なかったです。念のため。
アンドロイド用のStudio One Remote出ました。
外部デバイスからのコンソール調整は履歴に反映していなかったんですね？これが反映するように改善。
テンポチェンジを含むMIDIファイルのエクスポートで壊れるのが改善、て結構重要ですね。
3.5にしておかしいな？と思われていた方はfixedの項目のチェックをされると不具合だったかがわかるかもですね。
