«Bjorklund Toy» by rinalka1227

on 21 Apr'21 11:01 in pluckbjorklund

Toy built to facilitate experimenting with Bjourklund to step through two different 'chords'. The "onChord" is used in some way for each Bjorklund hit, and the "offChord" for all other times. The chords can be played as a chord or sequenced in some way. Chords can be generated with white notes only or all notes. In addition, there are controls to play with various related patterns All of the sounds are generated with the Pluck ugen, played through JPverb

nice! i had to add the following to my supercollider...

Quarks.install("Bjorklund"); Quarks.install("miSCellaneous_lib"); //needed for PLbindef Quarks.install("wslib"); //needed for midiname

rinalka1227 user 23 Apr'21 12:16

thanks. i should have pointed out the quarks. I'm new to this.
