Having recently switched from Pro Tools over to Studio One, there is one plugin that I miss the most.
It's call Var-Fi, it is part of a bundle of plugin that come with Pro Tools called D-Fi. What this plugin allows to achieve is the tape stop or start FX that you here on countless records. It is not a real-time effect, rather it is applied and baked into a selection of either one clip/event or even multiple selections, clips/events.
The cool thing about it is that you can apply it in two ways, one that keeps the original length after processing and the other extended the length.
There is no other plugin on the market that works this way and if you are a Pro Tools user, you will understand what I mean.
Please devs at Studio One, this is one feature request I hope you will consider.
Here is a video of Vari-Fi in action
