Waldorf Blofeld knob-per-function controller
|Some 130 knobs & sliders, almost 60 buttons and switches.|
The Waldorf Blofeld is a brilliant device with an extremely flexible sound engine, but navigating it's interface gets tiring. I designed & built a custom controller which turned it into a proper knob-per-function synthesizer with up to ~16 voice polyphony - an extreme rarity, and a joy to play with.
All Blofeld sound parameters are mapped to unique sliders or knobs, making them instantly available. The built-in display shows last moved value, which aids in precise inputs.
On some occasions, I merged some inputs into one knob where it made sense (e.g. glide on/off + glide mode). Arpeggiator params are unavailable, as that alone would take another 30% of space, and I prefer an external sequencer anyway.
Modulation sources and mod matrix are edited by pressing and holding the relevant slot button (+ source or destination buttons) and entering selection with the big slider on the control module.
The controller also features a "sync" mode, where it queries the Blofeld for current params and then guides the user, knob-by-knob, slider-by-slider, which inputs must be moved in order to get their positions in sync with current Blofeld settings. This allows for getting an overview of a sound recalled from Blofeld's memory simply by looking at knob positions after syncing.
In the future, I intend to document my design decisions, production costs, other challenges, and what I've learned in the process.

|Alongside my Blofeld. The board measures ~59x24cm, so it isn't small (hand for scale) - but that's unavoidable with the number of params on the Blofeld. I didn't go for tiny knobs and ensured comfortable spacing between them to make precise input effortless.|
