Катя Н.
Made a minute-long track in an evening — no DAW install.
Daniel K.
Love the filter sweeps. Classic 80s vibes.
Ирина В.
Computer keyboard maps to synth keys. Different octaves possible.
Алексей П.
Thick sound, not like free plugins. Surprised by the quality.
Олеся (Ольга С.)
Would love an arpeggiator — auto-arpeggio from a chord.
Роман К.
LFO and filter modulation — real synth, not a toy.
Дарья И.
The Lead preset is my favourite. I play melodies over beats.
