Courage, imagination and trust of one of my clients enabled me to built a regal, that to my knowledge has never been made like this. A pedal-instrument with two stops in 16 and 8foot range, which can be used together with harpsichord.
Both stops can be altered in volume and colour with lids and leavers, independently for treble and bass.
The instrument serves as practice arrangement with harpsichord or could for continuo-playing provide or enforce bass or double-bass range. First tests make me confident, that this organ might become similar siblings.
