The Haarlem Sessions

In the Summer of 2016, Federico Solazzo visited us because he was curious about the C15. He is a very experienced and versatile musician, a proficient synthesizer expert and sound designer. We decided to give him one of our C15 pre-production units for a few weeks. We wanted to find out how the C15 would inspire him in the way he plays keyboards and designs sounds.

In October we brought a C15 to his home in The Hague (NL). Federico started to explore the instrument and created a collection of his own presets. We asked him to think about a number of music pieces or improvisations that would show some characteristics of the instrument in a video recording session.

As a location we chose Studio Helmbreker in Haarlem (NL) where Federico had recorded the latest album with his band "Azure Hiptronics". The main room has a great sound and atmosphere.

We were very lucky that two other members of the band - Luciano Poli (bass) and Satindra Kalpoe (drums) - joined in for some of the pieces. The recording took place on the 6th of December, 2016. Bowie Verschuuren was the man behind the camera. All tracks were recorded 100 % live; no overdubs or effects were added - only slight EQ-ing and limiting was used.

Please check the text under the videos describing the control elements Federico was using when playing that piece.

Early Audio Demos

In mid of December 2015 we invited Jojo Büld, a professional keyboard player and composer, to play the C15. It was his first time with the instrument. Below are some audio clips from the recordings of his spontaneous improvisations. The last audio file is a collection of snippets (played by Stephan) that reflects the noisier side of the instrument.

A visit at Nonlinear Labs

A video about our work and the dual approach to the user interface of our first instrument. It was released in January 2015. Brian Smith (big brain audio) gives his impressions of a visit at Nonlinear Labs, where we showed the state of the product development at that time.
