Load an initial patch and use the visual modulation displays to understand how movement changes the sound. Experiment with one wavetable and envelope before adding layers.
Save original presets, and compare levels when auditioning patches so loudness does not disguise differences in tone. The official pages list the full synth, 75 presets and 25 wavetables, with the Basic pack marked free. The comparison describes the full synth in each tier; larger content libraries and service benefits distinguish paid options.
