CatSynth Pic: Roland D-50

The D-50 was Roland’s flagship and most popular synthesizer in 1980s. It employed so-called “linear arithmetic synthesis”, which combined sampled (PCM) transients with a variation on subtractive synthesis, including resonant low-pass filters. It also had a joystick. It remains a popular instrument for its pads and other characteristic sounds. Roland released a re-creation of it for their “Boutique” line, the D-05.

CatSynth Pic: Kurzweil K250

The K250 was the first of the Kurzweil’s “K” series of synthesizers in the 1980s and 1990s. Released in 1984, it was among the first to allow ROM-based samples to be layered and played on a keyboard – although the Synclavier and Fairlight CMI already offered sampling at this time. But it did have features such as variable rates and 16-bit sources that gave it the ability to play long samples and get closer to that holy grail of sampling a grand piano – indeed the K250 was supposedly inspired by a bet between Ray Kurzweil and Stevie Wonder on whether he could make a synthesizer that sounded like a “real piano.”

Big Merp with Yamaha RX5 Drum Machine

Big Merp has taken to our recently acquired Yamaha RX5 drum machine. I think he will be ready to lay down some rhythm tracks soon. He also has his rear paw on another recent acquisition: the Buchla Red Panel 158 oscillator. Look for these two instruments featured in upcoming episodes of CatSynth TV!

Back in the late 1980s when I was getting into synthesizers, Yamaha’s DX series dominated the landscape (along with Roland’s D series). I got Yamaha’s “After Touch” magazine which featured new releases including the RX5, which became the flagship of their drum-machine line. It was beyond my reach then, but I now I have one and looking forward to seeing what I can do with it in our eclectic studio at CatSynth HQ.
