YouTuber gattobus did one of the best OP-1 jams I've ever heard. Ordinarily I'd link over to where you could buy an OP-1, but you can't. For reasons that elude me these little devices from 2011 have seen a huge spike in popularity recently.
This song was entirely composed and performed using Teenage Engineering OP-1.
The main track was played in real time, the other 3 were recorded on the OP-1 internal tape recorder using internal sounds only.
Eventide Space and Korg SDD-3000 as master FX. A little bit of EQ and compression through Ableton live.
It's been 6 years since I got this wonderful little toy and I'm still in love with it. One of the most creative and inspiring instruments I've ever owned.
