Announcing the MODEL 28 PROGRAMMABLE TAP CLOCK
2007-05-08 by (i think you can figure that out)
Shipping of the Model 28 is to begin in three weeks. For a complete product description and picture, go here: http://www.ear-group.net/model_28.html Product Summary: The Plan B Model 28 Programmable Tap Clock is the second computer-based product in the Plan B line and addresses the need for an accurate tap input-based timing clock for analog synthesizers. Unlike other clocks, the Model 28 has no frequency pot -- it's tempo is determined by replicating an interval set by two successive depressions of the TAP INPUT button, or by syncing to it's PHASE LOCK input to an external clock. The M28 may be accurately programmed during a roll-off or three count in live performance - it is meant to be played and it's operation has been intelligently designed to support that in real time. Along with the quarter note base duration, the M28 provides separate eighth note tuplet and eighth note triplet outputs and approaches these rhythms in the same manner musicians do -- by multipling the tap tempo, not by dividing. The last tap interval read becomes its quarter note base, with the eighth-notes being base x2 and the triplets base x 3. All outputs are held at 50% duty cycle and tempo-accurate within 6 microseconds, with a playback range of a quarter note = 1 (1 beat per minute) to 2500 (2500 beats per minute). Along with the three parallel event outputs, the M28 is equipped with a single SERIAL OUTPUT which allows the user to construct polyrythmic combinations of the three note values, determined by a voltage level present at the SELECT input. The Model 28's musicality is further enhanced by a series of five ARTICULATION SWITCHES which introduce expression by either omitting (a rest) or dynamically accenting each degree of the eighth and triplet events (see figure 3). When an accent is selected, a second pulse is sent to independent ACCENT outputs which can be routed as a filter frequency chiff, or to the Velocity Input of a Model 25 VCA, or to the secondary VC Input of a Doepfer A-132, etc. The Accent Outputs are intentionally soft (gates are rounded at the corners) to avoid any pops caused by abrupt changes in amplitude. Two expanders are planned for the M28. The 28A will add Triangle, inverted Triangle, Ramp and Inverted Ramp outputs to the quarter and eight note clock outputs. The 28A will begin shipping in June. The 28B will follow soon afterward and will provide for MIDI out of the M28 clock information.
