    1. Good memory!

      When it was originally introduced, be noted: “TE says that the new Line module will be available Spring 2022. Pricing is to be announced.”

      Now it’s spring, it’s available and it has a price.

    1. They already sell knobs. those tiny little colorful knobs on their website. Whats next is an HDMI box with their ipad app on it so you can plug it into a screen and VIOLA, no ipad needed to program this thing since you obviously cant use it to its full potential without the app. If so, you must be on a deserted island with only a OP-Z or one of those guys that master hard things for fun like using a portable synth with semi-usable UI. It does feel good in your hands though.

  1. It really feels like this could have been a software update to the oplab module… But then again you wouldn’t be able to sell the same thing twice.
