Rumbler Compact Synthesizer is based on the OS of a Kawai K1 from 1985. Rumbler has3 oscillators: Saw and Square wave oscillators and a Wave oscillator using waveforms. It also features Ring Modulation with an internal Sine oscillator modulating the Wave oscillator.

The Wave oscillator contains 228 waveforms: 8 High quality waveforms and 200 8 bit lofi waveforms. Combined together they give the synthesizer a unique sound. 1985 meets 2022.

This device is for everyone who wants to:

• Have a collection of the original instrument patches of the Kawai K1 ROM bank D.

• Build instruments sounds from the Kawai K1 and save them as patches for use in Reason.

• Have a lofi 8 bit character synthesizer as an addition and counterpart of synthesizers with very clean oscillators.

• Have a high quality basic waveforms synthesizer with very clean oscillators as well.

• Make sounds or instruments for use in genres like ambient and movie scores, but also for popular based songs.

• Go modular as Rumbler Compact Synthesizer has CV in and CV out.

• Make use of the 8 cool effects as Rumbler Compact Synthesizer has audo in.

Gratulations on the release

On top of the synth, you get a bunch of fx which can be used

Fan of Kawai K1! Really like this. Congrats on it! Great to have the back of rack so nice for us nerds with the CV jacks!

Nice to see you like the addition of CV in and out.

There was a request during betatest for more modulation slots.
Once implemented the graphical interface would change drastically resulting in a U9 monster.
One solution to add modulation was the implementation of CV in and out on both the synthesizer section and the effects section. So, I went bonkers and build as many CV sockets as possible.

Congrats!!!
