RdPiano
RdPiano accurately emulates SA-synthesis digital pianos, such as the Roland MKS-20, RD1000 and the Rhodes MK-80 electric piano. It simulates the CPU-B board reused in different models, emulating the CPU and the custom chips. The emulation of the custom chips is derived from silicon analysis. It also approximates the BBD chorus and tremolo effect, albeit less accurately than the digital emulation.
