For now, yes it is available...B2M— Universal Bass to MIDI Converter
Following on from the success of the G2M, the B2M brings affordable and reliable MIDI capability to bass guitar. With ultra-low-latency, and unmatched affordability, the B2M breaks new ground in MIDI performance for bass players -- it will even track a low B (which is only 30Hz)!
The B2M™ is a simple-to-use, highly effective, bass-to-MIDI converter. It is “Universal” because it doesn’t need a special pickup mounted on your bass guitar, but instead simply connects to your instrument like any other effects pedal or tuner.
It is a true plug-and-play solution for monophonic MIDI bass guitar designed to give accurate triggering with very low latency. It can be used to sequence bass lines and add an edge to your live performances — it opens up many creative possibilities.
