The "Bass Synth" intuitive layout allows you to quickly create amazing sounds and the volume of the bass signals output from SYNTH OUTPUT which converts the bass sound from the input bass sound emulates and deep pulse sound with stacked voices. SYNTH control controls the volume of synthesizer sound output from SYNTH OUTPUT. Using both controls at the same time will achieve the same effect as mix control. The SENS control triggers high and weak plays and adjusts the response until synthesizer sound rises, and fine-tunes depending on the base and playstyle response. CTRL knobs adjust the parameters each of the 11 syntheses types. Effects vary from preset to preset and can be fine-tuned to customize the sound. The EXP input also allows you to control the exact parameters in real time with Expression Pedals. Preset foot switch allows you to store and call 11 customized synthesis sound presets. Factory presets can be restored at all times. Bass Mono Synth delivers a cool bass synth collection to your fingertips, from rich, warm sounds to sharp, penetrating percussive sounds.
