Sequential Discontinues The Tempest

via @sequentialLLC

"After nearly 9 years Sequential’s 6-voice analog drum synth Tempest is retiring. To get one while stock lasts, check with an authorized dealer or contact us at for referrals. On the bright side, we’re as busy as ever designing new products, so stay tuned!"

See the shop banners on the right for availability. Update: Original intro video from Dave Smith and Roger Linn added below. See this post for the initial announcement of the Tempest including additional pics and videos.

More than just a drum machine, the Tempest was a 6 voice synth with an engine similar to to the 4 voice Poly Evolver and mono Evolver.

via Sequential: "Each of the six analog voices has two analog oscillators plus two digital oscillators (with a large bank of included samples), the classic Curtis analog lowpass filter with audio-rate modulation, an additional highpass filter, analog VCA with feedback, five envelopes, two LFOs, an extraordinary variety of analog modulation routings, and stunning sonic quality, warmth, and punch. Although optimized for drum sounds, it excels at tuned sounds as well, and even doubles as a six-voice analog keyboard synth."

  1. Comparing the signal diagrams of the Tempest and Evolver, the Tempest is no Evolver, by a long shot.

  2. Would this mean Sequential are working on a Rythm machine ?
