Buchla 252e LEM3 Spider Polyphonic Rhythm Generator

   (0 reviews)

Buchla LEM3 Spider Desktop Polyphonic Rhythm Generator with Flexible MIDI and USB control to DAW’s, Eurorack and other devices.The 252e sequences pulse patterns and CV values stored in the cells of eleven concentric rings. Ring cells resemble the stages of more conventional sequencers, but the architecture of the 252e allows for interesting and unusual possibilities not previously available.

Four pulse outputs and six CV outputs can be assigned freely amongst the cells. Each of the three clocks
can be assigned to any of the 11 rings and synchronized to generate two- and three-part polyrhythms and polymetric patterns. Pulses and CVs can be shifted independently within a ring.

Pitch and velocity CV pairs can be captured from MIDI input – while editing and during performance. The 252e can synchronize to - or generate - MIDI clock. A Euclidian pattern generator is included to serve as a rhythmic library.

MIDI-CV interface:
+ 5-pin and USB MIDI input for a single synth voice with 1-1.2V/oct voltage conversion, jack/multiple conversion and scaling buffers for interfacing.
+ MIDI outputs for several standard controllers (re-assignable via MIDI) are available on the module.
+ Multiples can convert between 1/4″, 1/8″, Tini-Jax and Banana jacks.

CV-MIDI Interface:
+ 6 channels of CV-MIDI conversion.
+ Each channel accepts pulse, CV, velocity, and a CV input assignable to continuous controllers.
+ Extremely flexible MIDI control to DAWs and other devices.
