Product information "Doepfer A-157 Trigger Sequencer System"
Complex and really powerful trigger sequencer with eight rows á 16 steps, polyhythmic functions, really flexiblly assigneable CV inputs and more. It's delivered as three, freely placeable, modules: the master unit, trigger output module and a controller input module.
Features currently implemented (as of May 2016):
eight tracks of up to 16 steps each
step programming using matrix grid, or real-time programming
shifting selected tracks step-by-step
invert and copy functions for quick track creation
individual number of steps for each track for creating polyrhythms or odd time signatures
four different playback modes for each track (forward / backwards / pendulum / random)
track mute
each active step puts out a +12V trigger via A-157-2 trigger output module. In the final version, trigger levels will be programmable individually for each step.
start / stop / reset / clock (shifting step-by-step) functions can be controlled manually or remotely, using the A-157-3 control input module

WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
