251e Quad Sequential Voltage Source



Four 50 stage sequencers, each with programmable pulse and control voltage outputs. A separate editing section permits setting each parameter for a selected sequence; sequences can be edited while running and follow the edit stage when stopped.

Intervals may be entered for each stage, with variable note values from 1/32 to whole notes. Triplets and dotted notes are readily accommodated. Pulse durations may be set to fractions of the intervals.

Output voltages range from 0.0 to 9.9 volts, conveniently accommodating oscillators with a sensitivity of .1 volts per semi-tone.

Tempos may range from 10 bpm to 250 bpm.

Additional features include:

  • Inter-sequencer triggering
  • Variable start delay
  • Retrograde capability
  • Multiple nested loops
  • Master voltage-controlled clock

A 200eUSB card is necessary to download new firmware for this module.

With the help of a 206e or 225e Preset Manager, the parameters of the 251e can be stored and retrieved as part of a preset.

***PLEASE NOTE*** While Buchla is spending the first part of 2017 making systematic improvements in order to upgrade your overall customer experience, products may take 1-4 weeks for delivery. Once an order is placed, we will contact you right away with an ETA. Ultimately inventory levels should be good so that there is never a wait, but we do appreciate your patience as we all go through this together -eric fox and the gang
