Thonk Synth DIY
Sebsongs Rhythmatic is a fully featured analog dru Sebsongs Rhythmatic is a fully featured analog drum machine with six voices from the classic Roland CR-78. Buy now in assembled OR DIY form at Thonk via the link in bio or visiting Thonk.co.uk It has Bass Drum, Snare, Conga, Rim, Hats and Cymbal, expanding on the original with adjustable tune and decay controls. A key feature of Rhythmatic is the big knob in the top centre. This knob and CV jack control a random parameter, adding or subtracting steps from the pre-programmed patterns. For a more busy pattern, turn clockwise, more sparse? turn it the other way! Use it live performance to add quick random fills on the fly. Holding the shift button turns the random knob into a 4 bar loop to record pattern changes and movement on the random knob. Modulate it with whatever you want via the random CV input. Sequence externally or internally, with 64 programmable drum patterns. Program either using the buttons on the front panel, or via USB with the online pattern editor. Original CR-78 factory patterns are included and can be edited, stored, and switched live via CV. Each drum voice can have its own sequence length for experimental polymetric sequences. The factory patterns contain many of the original CR-78 patterns plus pattern banks created by Sebsongs Modular, Konstantine and Salkinitzor. Each individual drum has a mute option with clear LED feedback for performance. Each drum has a configurable input/output for each of the voices which can be set as either: trigger inputs for external sequencers or as trigger outputs for controlling other gear from the built-in sequencer. Rhythmatic features internal swing per pattern and has clock and reset inputs for syncing to external clock sources. There are two audio outputs: output A contains the full mix of all 6 voices, but inserting a patch cable to output B splits the voices in half between the two outputs. All in all Rhythmatic offers a fresh twist on the classic sounds and rhythms of the CR78, with programmability and live performance features that make it a unique addition to any rack.
