Coole App!

Mit wirklich starkem 303 Sound und sehr leicht zu bedienendem innovativen Sequencer. (Wesentlich besser als beim 303 Original). Schade ist nur, dass man diesen Sequencer nur Standalone benutzen kann und zum Beispiel nicht innerhalb von AUM und zusammen unserem Drum Sequencer OCTACHRON, was ich natürlich gerne mache. Dazu braucht man dann noch die Rozeta Suite, was bei diesen sehr moderaten Preisen allerdings auch noch okay ist.

Sequencer en modo AUv3?

No entiendo por qué solo esta disponible el secuenciador en modo standalone le resta versatilidad y su principal encanto
