Note that OTTO departed from OP-1 and doesn't attempt to clone its features. E.g. the "tape" has been removed, source: https://github.com/OTTO-project/OTTO/pull/66 . Instead they plan adding: "A simple loop-station-style audio looper that can get audio from line in or synth. It has overdub and one level of Undo.", source: https://otto-project.github.io/docs/

Many people here are discussing OP-1 and complaining its expensive price. There's a open source clone called OTTO[1], and it looks promising (although not finished). [1]: https://github.com/OTTO-project/OTTO

Gonna take this opportunity to plug an open source project I've been following for a bit: https://github.com/topisani/OTTO. Essentially, they are trying to create an open version of Teenage Engineering's OP-1.

I had one of the original 2012 Model B's (with the 256MB RAM) serving as a simple web server for years. I just recently retired it in favor of a VM. Other than that, I have: - A RetroPie attached to my living room TV - A Zynthian (http://zynthian.org/) - A PiDP-11 (https://obsolescence.wixsite.com/obsolescence/pidp-11) In the past, I've played around with them, making: - A touch-screen enabled stand-alone SunVox synth - A home audio server attached to my stereo - An experiment to read MIDI files from floppy disks, also attached to the stereo I have a couple spares laying around waiting for use cases... but I'm not really antsy to get to them. I'd love to build an OTTO (https://github.com/topisani/OTTO) when it's ready for prime time. I'm also considering building some sort of portable RetroPie.

Promising similar open source project : https://github.com/topisani/OTTO The progress made by the guys these last months is impressive, and both the UI and hardware aestetics really shines (while they are inspired by the OP1, they now have their own personality)

Also worth mentioning is OTTO [1], an open source effort to recreate OP-1 on Linux / RaspberryPi. [1] https://github.com/topisani/OTTO
