BK-7m USB MIDI Issues 26 May 2015 14:10 #2181

Hi Guys,

I am an old(ish) but fairly experienced musician ;) but I'm new to the world of the Roland BK-7m (ROM v1.07). I have a small home studio running Digidesign ProTools V8 on a windows 7 based PC. I have various bits of midi gear that all talk to each other seamlessly. My BK-7m is another issue!

My first aim was to use the BK-7m in 'sound module' mode so I have connected the BK-7m via USB to the PC and set up the midi studio part of ProTools, BK-7m Midi in and out on all 16 channels. If I create a new midi track I have the option to route the midi signals where I choose so as an example I can play notes on my Kawai MP5 digital piano (also connected via usb to the PC) and route the midi signal to midi channel 1 on my Roland U220 sound module. When I play notes I can see the midi signal triggering the U220 and hear the module playing. I have tried setting up the BK-7m in the same way using the wizard connection in Computer/Sequencer mode but I cannot hear anything from the BK-7m.

Anyone got any ideas where I am going wrong..... please :S

I am a Mac guy, so I can't help too specifically, but the first thing I'd check is whether you have the correct PC USB drivers installed for the BK-7m roland.com/support/article/?q=downloads&p=BK-7M and then make sure ProTools has the correct MIDI setup loaded.

Do you see the BK-7m as a Device in ProTools?

Hi Diki
Thanks for your response. Yes I have the correct drivers installed. I can see the BK-7m as a device within windows and I can see it in ProTools. I had another play last night and I can get ProTools to work fine (although with some latency) when I use standard 5pin midi cables. Just not whilst using the usb midi.....

So ProTools is sending USB MIDI OK to other devices?

OK, try this. Set the Wizard to Master Keyboard 'One Channel'. When the Wizard asks you to '“Play a note on master keyboard” Have ProTools route ONE note on any particular channel from the master USB controller. If the USB is working, you should see the Wizard pick up on that note.

I guess one thing you MIGHT try is powering everything up in a particular order.... Do you tend to have the computer on, then power up the BK? Try shutting the computer down, power up the BK (hook up the USB) and then boot the computer... (or if you already do that, try doing the opposite!).

Another thing might be to look at whether you are hooking the BK into a USB hub... Try plugging direct into the computer if you do. No guarantees, but these are all basic things to try out and see if anything works.

I'd also try hooking the USB that you use for the BK into the Kawai, and see if it makes any noise. Maybe you have a bad USB cable?

Oh, and don't forget to check whether you are running in 32bit or 64bit Windows. Make sure the driver is the correct type.

After all that, I'm at something of a loss. I don't suppose you've checked the BK's headphones out, or ran a demo sequence from it, to double-check the simple audio connection? Does it make any sound when you simply hit 'START'? I imagine you've thought of that, but I'm just throwing out basic troubleshooting stuff! :lol:

Lastly, have you contacted Roland Tech Support? In the US, it's www.rolandus.com/support/email_support/ Who knows, they MIGHT have a clue!

Keep us posted about your results... :huh:

You mentioned "some latency" when using standard MIDI cables, that's strange. There not suppose to be any latency not with midi cables nor with USB.
BK7m does not require any driver installation, like many modern devices it communicates with Windows directly thru USB port.
What MIDI interface do you use when connect standard MIDI cables? Latency usually is the issue with VST instruments, not with hardware synths. Is there a latency with U220? Try to connect U220, then put the very same cable into BK - is there a difference in latency?
As for MIDI configuration of BK, go to Menu > MIDI > Edit Song Parts. Each of 16 parts must be set to RX=on and midi channel of each part must match the part number.
I was angered, for I had no shoes. Then I met a man who had no feet.

You can find latency on all of the other major DAWs but I don't remember to have latency on USB port..
Anyway, try to set your buffer size on Pro tools to resolve your latency and use a good quality MIDI cable...

Don't confuse audio latency with MIDI latency...

For all practical purposes, you should not hear any difference in latency between directly hooking two pieces of gear via MIDI or going through the computer MIDI interface or the USB MIDI connection...

What MIGHT be happening here, though, is that Bagpuss is monitoring the BK through his computer DAW, rather than directly. This would introduce whatever audio latency his system runs under to what he is hearing. He needs to enable 'Direct Monitoring' or whatever system his audio interface has for outputting the direct input, NOT the sound after it has gone into the computer.

Allow me to disagree. DAW buffer has nothing to do with hardware MIDI. And bad MIDI cable would not add any latency, there will be hanging notes, lost midi signal, but not latency.

Hi All !
Thanks to you all for your help. It would appear that I had a dodgy USB cable. After replacing it I now have USB midi working fine. I also removed the 'Roland-Arranger' drivers and reverted to the standard windows drivers.

So... a little off my original topic, is it possible to 'design' our own styles for the BK series arrangers. Maybe by using some midi arranging software? Put down a drum track, bass line etc etc then save it in some format the BK series can read and play back? I know they can play SMF but it would be interesting to create new styles based on songs? I would love a 5/4 style to play the classic Brubeck tune - Take 5....

PS... I think my midi latency is being caused by the fact my Kawai MP5 is connected via USB and my Korg sound module is connected to the Midi Out port on my Digi002. (So the midi signal is being passed via usb by the computer to the midi hardware built in the the Digi002, hence causing a bit of lag/latency) Does that sound feasible?

;)

And another quick question for you all...

As I said earlier in the thread I use ProTools V8.0.1 with a DigiDesign 002. Protools uses Instrument Definitions to call sounds from sound modules. I ws wondering if anyone knew if there was a set of definations for the BK-7m so I can access all of the 1000 sounds rather than just using a GM set and only accessing 128....

(Should I start a new thread each time?? :ohmy: )

You should hear no difference in latency between USB MIDI and conventional MIDI. Did you check what I said, and made sure you are listening to ALL instruments directly, with no trip through the computer's audio system?

You might also want to search around the web for some Roland 5/4 styles. There are several out there. Try this (no guarantees)

The BK-7m does not have on board style creation and editing. In order to do that you have to buy a BK-5 too. Or you could just sell the BK-7m and get a BK-9 which has the best tone generator features of the BK-7m plus on-board sequencer and style creation.

I played around with the BK-5 and BK-9 quite a bit in the store. I found the style editing and creation workflow to be kind of buggy (search my other posts on this forum.) If you're really serious about making your own styles I would consider a board from the previous generation: E-50, E-60, E-80, or G-70. There are no new style parameters (at least not documented in the manual.) So styles created on previous-generation boards will work on the BK-7m. If anything they may sound better! Perhaps someday Roland will tighten up style creation on the BK's but i'm not holding my breath.... -Ted

In the Files section of this forum there is a program "Style converter 4". It allows you to create a style from MIDI file.

(Should I start a new thread each time?? :ohmy: )

Actually, yes... you'll get better answers and more help by starting a thread for each question. Not to mention, make it easier for others later down the line to search for answers to the same question, and encourage others that may have surfed into the thread at the start, but decided they could not help to help you with a subsequent question they CAN answer.

Check out this post www.roland-arranger.com/index.php/forum/...-posting-suggestions for guidelines, please. It mentions making a new thread for unrelated questions... B)

Thanks dilletant, I'll give that a try
