It saddens me to see this happen, as it is not just Sonar, but also Rapture Pro (Dimension Pro) and Z3ta+ that will cease development. I do not think anyone at Cakewalk saw this coming, as they were still celebrating their 30th anniversary and were really improving in the last 2 years and especially last few months. I hope another party steps in and acquires them, as nothing good can come from staying at Gibson... they have called Opcode before and Deckadance (under the Stanton brand).
