In the world of Rob Papen synthesis he lacked a kind of synthesizer. A synthesizer that has all controls and features available all at once visually.
The current collection of Rob Papen contains synthesizers containing many features and types of synthesis that can sometimes be daunting for the average user. But there is always something tempting and fun into something that is so simple! Watch the 1980s, which had higher synthesizers as the Roland Jupiter-8, but also at the other end of the spectrum, simple but fantastic synthesizers like the SH-101. And yes, both became classic synthesizers. Compare it while also making music, often less is more and this can also be applied when using synthesizers. Of course, with a synthesizer with many functions, it can also be less complex in a patch. But often still it takes longer to achieve.
