There are a number of utility functions useful for controlling Zen.
clear() clears the console
scales() show all scales that can be used in the mini-notation
chords() show all chords that can be used in the mini-notation
samples() show all samples that are available to use
midi() show all available midi devices
loadSamples() load your own samples - see Custom Samples
exportCircuit(<format>) prints the current circuit to the console as a string. Formats are 'qasm' or 'qiskit'. Default is 'qasm'.
btms(<beats>) an alias for set(<beats>).btms(), allowing you to quickly set a time value locked to the current bpm. E.g.:
z.bpm.set('60 | 120')
s0.set({inst:0, dur:btms(1), r:10, e:'1'})
