Product description
The SoundPro X Left Hand Bass module is a dedicated MIDI board developed specifically for the bass button section of Italian and German accordions. This version is designed to detect and transmit only the bass notes, without chord (treble/mid-range) functionality — which is sold separately.
It is compatible with popular accordion models such as Weltmeister Supita, Cantus, Cantora, Stella, and others with similar bass-side construction. The board is made in Germany using high-quality components and offers stable performance, fast response, and long-term durability.
Installation is quick and straightforward: it mounts directly onto the aluminum bass levers where magnetic sensors and magnets are fixed. It connects easily to the main SoundPro X system or can be used as a standalone bass module within larger MIDI setups.
This module is ideal for accordionists who want to capture left-hand bass notes for triggering samples, virtual instruments, or synthesizers in live or studio settings.
