The oscillators features continuously variable wave shape and wide variety of modulation. The filters are modeled on Transistor Ladder filter circuit and the Sallen-Key filter circuit for classic analog sound. The Effects include delay, chorus, flanger, reverb, eq and compressor. The sequencer features piano roll and parameter automation editor to program 16 bar pattern per clip. Project files can be saved in iCloud Drive, so that the project can be accessed from iPhone, iPad or Mac. - Main Features - Virtual analog bitimbral synthesizer Two type of Lowpass filter, Transistor Ladder model and Sallen-key model. Maximum 8 voice polyphony. it depends on performance of the device it is running. Operate as monophonic or polyphonic. Patch points for modulation. Support MIDI 2.0 User Interface built by SwiftUI for improved performance. Built-in Sequencer. 16 bar patterns per clip. Total 8 clips. Piano Roll and Parameter automation. Support Audio Unit Extension (AUv3) Works on iPhone, iPad and Mac. Support iCloud Drive to share project files between the platforms. Audio Export.
