The Idea & Process

It's a unique mixture of physical modelling and fm synths recorded on a cassette with an old & wonky cassette recorder. It has a range from C0 to E6 and 4 carefully designed velocity layers. The GUI is very simple, yet useful and almost synth-like, so it’s very easy and fun to work with. For example, it has editable “sample start” parameter (controlled with the GUI or Mod Wheel), so you could easily get rid of the initial transients while designing your sound. Feel free to check out the introduction video's to hear and see it in action!

What's new in v1.1?

Cassette Keys.01 Kontakt Version

Cassette Keys.01 Ableton Live Version

Every note has been carefully denoised with a high quality algorithm to avoid noise stacking when playing more than one note (there’s still some noise left in the samples to avoid denonising artifacts). Noise can still be added with the noise knob - it’s much more flexible this way and allows the ability to adjust the volume of the noise independently whilst also applying parameters such as filtering. It also creates a more realistic sound, so when playing a five voice chord, only one sample of noise instead of five stacked on top of each other will be heard.

Useful and fun production tool

If you like vintage sounds and you're looking for something to enhance your production toolbox, then this product will be for you.

Simulated Round Robin

Makes faster note passages sound more realistic and adds to the overall nonlinearity of the instrument - available in Kontakt and SFZ versions only.

Variety of sounds

Aside from the sound of a cassette record with this instrument you can easily create some weird sounds and there are already quite a few presets included to get you started (Kontakt & Ableton Live versions only).
