D-Beam sensitivity on the BK-9?

D-Beam sensitivity on the BK-9? #6772
I was fooling around with the D-Beam on my BK-9 for the first time, and found it difficult to control.

According to its manual, the Prelude has a Global menu option to adjust D-Beam sensitivity. But the BK-9 doesn't seem to have any provision for adjustment. Is this yet another missing feature from the "orphan generation?" Any tips for improving control? I'm particularly interested in the Arpeggio and Chord functions, which require a bit more precision than just triggering sound effects, IMO. Thanks all!

There's d-beam calibration in the service notes, but no adjustments in the OS.

Hilariously, here’s the d-beam sensitivity section from the Prelude manual: This sets the D Beam controller’s sensitivity. The higher the value set, the more readily the D Beam controller goes to into erect.

LOL!

But overall it doesn’t really give you much more control than you currently get. No way to set upper and lower values, no way to scale it, no adjustment for what to ignore... Basically, just a way to set it up so you don’t have to move in so far, but that comes at the cost of falsely triggering it, which could be problematic.

My favorite use for it is to have it turn on/off the bass and drums, which combined with setting up the Track Mute to be Bass and drums only gives you considerable control in remixing a style on the fly... you get full style, ACC only and Drum and bass only with two easy to get to controls, and it doesn’t take a high degree of finesse..!

BTW, the D-beam assignments are per Performance, whereas the Track Mute assignment is global, with two setups, one for styles and a different one for SMF’s (and center cancel for audio). So if one Performance has the d-beam muting Bass and Drums, another can mute bass only, or drums only, so whatever the style needs is catered for. In fact it’s easy to program different Performances placed next to each other in the List where you can change the assignments on the fly.

Sure wish the Track Mutes were per Performance... in fact, I wish that there were no Globals, LOL A different FC-7 setup per Performance is badly needed.

Good suggestions Diki.

Part of my problem is that my main overhead light for the room is directly above the keyboard. That light shines directly into the "eyes" of the BK-9. And if I turn out that light, there might not be enough light from other sources for the D-Beam to operate properly.

D-beam works in complete darkness, it has nothing to do with visible light. I think it’s infrared...

Perhaps you can use indirect light (reflected from the wall or ceiling), that works for me.

I'll test it with indirect light the next time I'm inclined to experiment.

What I really want, is a multipad-like function to trigger chord-matched arps on demand. On the BK-9 it looks like my options are the D-Beam, or the audio keys. Because the D-Beam is chord-matched, that seems like a better choice. I was disappointed in how difficult it was to control reliably. Why didn't Roland use a ribbon controller, or something less exotic? Has anyone "hacked" the D-Beam and managed to trigger it with an external MIDI controller??

In addition to the BK i also have a Tyros 5. It has true multipads, including some factory content like piano arps. I know it's possible to drive the Tyros with MIDI From another arranger. Sometimes two arrangers are better than one...

As I said, the D-Beam works in anything from complete darkness to bright outdoor sun. It’s either infrared or something invisible like that that generates a form of light that gets reflected from your hand as it approaches. Ambient visible light has zero influence.

Audio loops are possible to do arpeggiations, but they aren’t chord following. You’d have to prepare one for each chord you are going to use and better hope you don’t need more than twelve!

I’m not sure the d-beam as strummer idea would work out that great, as guitar voicings aren’t used (wish the BK-9 had the G70’s Guitar Mode!) and there’s no detection of velocity, only speed. It’s all a bit theremin-ish and that was a notoriously difficult instrument to master.

What you are looking for sounds like the Tyros is the only answer, you could go down a rabbit hole trying to control a gestural controller!
