RFM's ELEKTRAX is a 4 track sequencer intended as a simple 'drum-machine'. Each of the 4 tracks have dials to set the pitch, decay, wave (from sine to saw), bend, bend time, noise, level and pan. You can choose to set a speed independent of your DAW/APP or sync instead. If synced, you'll choose a speed by setting a note duration.
And although ELEKTRAX is intended as a drum-machine, you could use the SAWTOOTH wave with longer decays to create simple 4-note basslines..
Further there are of course inputs to reset, start or stop the sequencer. ELEKTRAX also has outputs for PITCH-CV that you could feed into any oscillator, and ENVELOPE signal per track to drive filters or amplifiers.
By chaining multiple ELEKTRAXs, by driving the start of a following ELEKTRAX with an ENV step you could have real complex rhythms. Lots of room for experimentation there!
