Adaptive Surround Reverb (ASR) Since a few weeks our new Platinum Edition Sweelinck , Rembrandt  and Monarke organs are equipped with a new type of internal reverb. We call it Adaptive Surround Reverb (ASR -12). This new reverb is a stunning new development, that improves the reverberation to a level never reached before. But there is more. A very strong item to promote sales is, the twelve organs in one concept. It is great to change from Romantic to Baroque, of from Solo to Hymn. However the reverb was always the same. From now on every sample bank and intonation (so 12 together) has its own reverb. Try it, it’s a great invention and a prove of the leadership in organ technology by Johannus.
