## Description

Simple FM synthesizer that can be edited while viewing waveforms.<br>Seamless integration with our software MIDI keyboard application &quot;Midikeys&quot;.<br>Connectable to hardware USB MIDI keyboards and wind synthesizers.<br>Pure sawtooth wave and white noise oscillators, which are difficult to achieve with FM synthesizers.<br>Share the sound parameters you create with other users.<br>*The number of oscillators available and the number of simultaneous sounds depend on the specifications of your device.<br>*Data storage is available through in-app purchase.<br>*Use with Bluetooth speakers or earphones may cause delays and noise.<br><br>＝About the characteristic parameters＝<br>＜Oscillators＞<br>Gain: Power off at 0.00. To increase the number of simultaneous sounds, reduce the number of oscillators.<br>＜Polyphony＞<br>Glide Switch: When using with keyboard, use &quot;Double notes&quot;; pressing two keys at the same time will glide the notes. When using a wind synthesizer, change to CC65 or CC64.&quot; Double notes&quot; will always glide.<br>＜ADSR＞<br>S-Decay: Curved sustain decay. This function reproduces the decay waveform of a piano.
