"So if I have a melody line, I have two Minimoogs I'll address MIDI to then record simultaneously on stereo files. The Minimoogs sound wonderful. They're just the kind of 'out of tune' you want them to be. My trick is to then make a sample instrument from the stereo files. I usually record about 60 notes from the Minimoog and use the original Minimoog at the same time as the sampled one, which opens up a richness of sound. The melodic line on the track Nachtfahrt [taken from Off The Record] is four Minimoogs playing. They're MIDI'd and also the first oscillator is tuned."

In this interview, Karl talks about using the Roland MC-202.

A Korg PS-3100 was used live by Karl Bartos when he was with Kraftwerk.

In this interview, Karl talks about using the ARP Odyssey. An ARP Odyssey Mk III can be seen in photos of his studio.

"I'm happy if I can tell little stories with a Moog melody line. So the Minimoog, ARP Odyssey and the Polymoog became my signature. The ARP still works fine. It's great if I need to create a strange electronic sound."

"I'm using vocoder but speech synthesis at the same time. They meld well together and sometimes I sing phonemes along with it to give them more definition. You don't hear it but it's in there to support certain phonemes. I bought the VirSyn Matrix and it's perfect. I use all the other vocoders, like the Roland VP-330 and some others, but the Matrix is just so simple and easy to get a good sound that you can't beat it."

In this interview, Karl talks about using the Roland SH-101.

As the show drew to its close, ‘Pocket Calculator’ not only featured a reset rhythmical template but also footage of Herr Bartos showing off his synth inventory. The eagle eyed would have spotted with a Stylophone, Korg MS20, Minimoog rack mount, Farfisa Professional piano , ARP Odyssey and that iconic elektronisches schlagzeug unit.
