Gate-Seq-64 and Voxglitch Sequencer along with Phrase-Seq-32 are three powerfull tools in combining rythms and tunes.
Check Volts/Octave sheets in order to tune Voxglitch Sequencer to desired notes. Phrase-Seq-32 allows you to choose from a keyboard.
Gate-Seq-64 allows you to put a lot of variation due to songmode and advanced gate modes. If you’re not sure how those work, check Omri Cohen’s videos out (advanced gate modes and creative sequencing).
Pico drums can be modulated which is really great, pay attention though on which drum you are using.
If you want to do chords of course there are several chords modules but I went for putting beface even VCO and audible Braids in Pluck mode. Filters and Reverbs do their thing – I picked the AS and the Southpole (Camilla mode) ones because they add some very different spice to the tunes.
