D-50 is one of the most popular digital synthesizers not only ever created by Roland but ever emerged on the market. The 61-note velocity sensitive keyboard with aftertouch was released in 1987. It features 16-voice polyphony which becomes an 8 one in a split or a dual mode. The architecture offers bitimbrality, 32 oscillators providing 2 per voice while in dual or split mode there are 4 per voice available. The synthesis is based on Roland’s Linear Arithmetic technology combined with 8-bit PCM samples onboard. The structure includes 3 LFOs. The filter section is represented with a low pass resonant filter TVF (Time Variant Filter) while the amp is also defined as TVA. Memory stores up to 64 patches.
Roland D-50 received a TEC Award in 1988 beating Yamah DX7 in popularity and waiting for the Korg M1 to come and take its laurels already the next year. D-50 was among the first synths to offer digital chorus and reverb as well as to include sample-based sounds not being a rompler.
D-50 was also unique back then owing to its digital wave generating while many other synths used to fill their structures with complete PCM wave samples. D-50 used PCM to sample acoustic instrument attack nuances as well as delivered samples of famous analog synthesizers processed through the analog path LFO, filter, amp stages.
