Dave Smith (of Evolver fame) and Roger Linn (of the LinnDrum) have collaborated on a new analog drum machine, the Tempest:

Dave Smith Instruments today introduced Tempest, a new analog drum machine, at the 2011 NAMM Show. Tempest is a collaboration between Smith and longtime friend and fellow instrument designer Roger Linn. […] Each of the 6 analog voices has 2 analog oscillators plus 2 digital oscillators (with a large bank of included samples), Dave’s classic analog low-pass filter with audio-rate modulation, an additional high-pass filter, analog VCA with feedback, 5 envelopes, 2 LFOs, an extraordinary variety of analog modulation routings, and stunning sonic quality, warmth and punch. […] Two pressure- and position-sensitive Note FX slide controllers permit real-time recording of note or beat-wide sound parameter changes into the drumbeat as you play. For example, record simultaneous filter frequency, tuning, envelope decay and pan changes for each note, or control similar parameters affecting the entire beat.
