Sequential Circuits MultiTrak | Vintage Synth Explorer

vintagesynth.com

The Sequential Circuits MultiTrak is a vintage gem from the mid-eighties, offering a rich six-voice analog synth experience with sophisticated filters, envelopes, and modulation capabilities. Its standout feature is the onboard sequencer, which was advanced for its time, allowing for real-time recording and patch changes on the fly. While its programming interface might feel dated with a matrix keypad, the built-in stereo chorus effect and robust MIDI integration keep it relevant. With 99 memory patches and a price drop from its original $1,500 to around $300, it's a bargain for those seeking classic Sequential sounds.

SCI Multi-Trak (IM Apr 85)

muzines.co.uk

The Sequential Circuits Multi-Trak is a significant upgrade over its predecessor, the Six-Trak, offering professional-grade features that make it a worthy contender for serious musicians. With its six-note polyphony and advanced multi-timbral capabilities, it allows for intricate layering and sequencing. The velocity-sensitive keyboard and improved sound presets deliver dynamic and rich tones, further enhanced by a built-in chorus. While the sequencer offers robust editing options, its inability to easily insert notes can be frustrating. Nonetheless, the Multi-Trak's versatility and sound quality make it a winner, renewing faith in SCI's innovation.
