KORG M1

Digital synthesizer Music Workstation

The M1 was and still is a popular and widely used digital synthesizer and music workstation. The M1 features built-in AI Synthesis for full digital generation and processing using 4MB of PCM sampled and synthesized waveforms which can be shaped using analog-style editing. The M1 is capable of creating acoustic instruments with clarity, nice digital sounds and good buzzy techno sounds. The M1 is sort of like a workstation-version of the Roland D-50.

ROLAND D5

The Roland D-5 is a multi-timbral digital waveform linear synthesizer. Sounds (tones) are made from up to 4 partials that are created from either: 2 PCM waveforms, 2 digital waveforms, or 1 of each. It has 13 available routing structures for its partials, 8 of which include a ring modulator. It also features one note chord play and a key chase which is basically a note repeat that emulates a digital delay. The D-5 is similar to the D-10 and D-20 but without effects and an on-board sequencer. The D-5 was first released in 1989 by Roland Corporation of Japan.
