B2M—Universal Bass to MIDI Converter

Please note that the B2M has been discontinued and replaced with the new G2M(V3). All the features of the B2M (and more) are now part of the G2M(V3).

Following on from the success of the G2M, the B2M brings affordable and reliable MIDI capability to bass guitar. We have been inundated with requests for the B2M and we are sure this will bring delight to bassists the world-over. 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)!

  • Any electric bass guitar can be used as a solo MIDI controller.
  • No instrument modifications or special pickups required.
  • Robust note detection — minimises wrong notes.
  • Very low latency & very fast tracking.
  • Fast, accurate MIDI pitch-bend or chromatic mode.
  • Built-in tuner for standard bass guitar tuning (4–7 strings)
  • Battery-powered with long battery life.
  • Compact, lightweight and portable.

"Just want to let you know that after just a few hours of using the B2M, I am VERY IMPRESSED! I use it with my five string fretless AND with my double bass (piezo pickup in the bridge). It is surprisingly fast, accurate, and works well with passive pickups. It depends on the patch (I use a JV-1080), but I love being able to have a huge arsenal of sounds for my basses. Check out my weird stuff at www.patrickneher.com.

So, I love it and am amazed at its price and compact design. Now we need multi-channel selection!"

Universal Appeal

No modifications are required to your bass guitar; no special pickups to install; and nothing needs to be “stuck” onto your instrument. It works with all electric bass guitars without any setup or tweaking.

The B2M™ universally appeals to all bassists from novices to seasoned professionals. Keenly priced to fit any budget, with the robust reliable performance expected by the finest stagemen.

Incredibly simple to use:

  1. Plug your bass guitar into BASS to power-up the B2M™

  2. Enable CHROMATIC if you don’t want to send pitch-bend information
  3. Connect your MIDI device (or computer) to the MIDI OUT

  4. Play notes on your bass and MIDI will be sent directly to your midi device!

Powered from a single PP3 battery, its long battery life combined with small size makes the B2M™ the ideal accessory to keep with your bass. Not only does it provide fast and precise tuning, but it also gives you instant MIDI capability for any electric bass guitar!

  "The MIDI solution for all bassists"

Robust Performance

Research has shown us that the most important aspect for pitch-to-MIDI conversion is reliable and reproducible triggering of notes. While low-latency is important, robust triggering is the key to usability — you can easily adapt to some latency, but you cannot adapt to random, spurious notes.

By virtue of the unique, inherently robust technology used in the B2M™ you will be able to reliably generate accurate MIDI quickly and easily. Notes are generated exactly as played, and the nuances of your performance are captured with fast, accurate pitch-bend data. What’s more, you also get very low latency!

Built-in Tuner

The built-in tuner uses our PULSAR™ tuning technology where the power LED doubles as a tuning indicator. This innovative tuner gives you a fast and accurate way to tune your bass guitar.

Instrument Thru

Featuring a high-impedance input circuit, the B2M™ won't sap your tone when using it "in-line" before your amp, or other effects pedals. You can then easily combine MIDI sounds with your normal bass sound for some exciting musical possibilities.

Improves Playing Technique

For optimal MIDI conversion, your playing needs to be clean and accurate. Accidental notes, resonating open strings and other sounds can often be converted into undesired MIDI notes. Often you don’t hear these when playing the bass on it's own, but you can detect them easily when listening live to the generated MIDI.

Striving to improve MIDI note accuracy, encourages clean picking and accurate fingering, with good control over non-sounding strings by damping them.

Not only will your MIDI output be more accurate, your normal playing will sound clearer and more professional. It’s like having a tutor sitting beside you giving you advice. It’s also great fun!

Most of all, it's Fun!

When you try the B2M™ and generate some new sounds, the first thing that strikes you is how much fun it is. Unleash new creative inspiration and invigorate your soul.

See our guide to using the G2M™, which is equally applicable to using your B2M™.


Note: the B2M™ doesn't include its own MIDI sounds, you must use a suitable MIDI synthesizer, sound module or your computer to record or to hear the MIDI output.
