Synesthesia is an advanced, yet user friendly dual-channel multi-modulation engines, capable of running two modulation algorithms simultaneously. Packed with 38 classic and modern algorithms and 3 different DSP routing schemes Synesthesia offers limitless sonic possibilities.Synesthesia is not just another modulation pedal. By marrying a powerful dual-engine architecture with rich and deep algorithms we provide players with immersive and 'colorful' modulation effects experience, hence the name : Synesthesia. Up to 38 on-board algorithms - more may be made accessible via the SymmLab editor. Preset mode - conveniently recall your favorite patches from an easy-to-navigate banks of 32 presets.Stompbox mode - stomp the footswitches to control the individual DSP, just like using individual stompboxes. Comprehensive external control : Expression Pedal - with adjustable heel and toe values. Control Voltage (CV) - takes 0 - 2.5 V control voltages. Aux Switches - accepts up to 3 external switches for versatile control (tap-tempo, bank up/down, etc). MIDI In / MIDI Thru - nearly all features and functionalities of the pedal are opened to MIDI access, including MIDI clock. Tap-Tempo - you can tap in your tempo using an external tap pedal, via Midi, or on the pedal itself.Space saving - 12 cm x 12 cm (4.7" x 3.5"), impressively small for a pedal that can replace 3 or more individual stompboxes.Switch effects order (pre or post) effortlessly via the switchable Pre/Post configuration (specifed on per-preset basis).
