BK7m to E80 .... Single or Multi channel connection? #6332
Hi,

Need some expert advice please :)

I see when I connect my bk7m to my e80 it gives me a choice of either 'one' or 'multi' channel connections .... in what circumstances would I need to connect using 'multi' channel? Is there any downside to using one channel in terms of the 'output' quality of the BK7m ... I notice that chord changes can be a bit messy on busy styles, is that an issue or is it just me?

Finally, is it possible to use a pedal to select variation/ots through stages from 1 to 4? Can't seem to get the pedal off rhythm start/stop function.

Thank you.

Mike

I think a lot of that comes down to which chord recognition mode you're using. For example, if you play piano style I would choose "Digital Piano" which is all one channel.

The BK-7m was also marketed as an expander for MIDI accordions. Some accordions send their 3-note chords and bass notes on different channels. The connection "wizard" that runs when you connect is just an automatic way of making typical channel assignments for those unfamiliar with MIDI. But you can skip the wizard, or customize all of the channel settings after it runs, and then save the Global.

One of the most important parameters is the NTA or Note to Arranger. This is what the BK will use to determine the played chord. Honestly I'm not sure if it can merge input from more than one channel, or not. (If not I know MIDI solutions makes an external box that performs "midi merge.")

If you're finding your chord changes are messy, it's possible that you're not pressing all the notes at exactly the same time (within 0.02 seconds of each other.) Or it's possible that some notes are not being received by the NTA engine, so the chord is not recognized as intended. What chord recognition mode are you using?

As for the pedal, yes you should be able to assign it to "Variation Up" or many other things. Check the menus and don't forget to save the Global. Good luck!

On the E80,go to MENU>FOOT CONTROLERS>FOOTSWITCH,this takes you to the assign pages (4).
Unfortunately you can only select any of the 4 variations but you cant scroll all 4.

A MIDI Solutions footswitch controller could be programmed to send the MIDI message to change style variations or registrations. I have no stake in that company, except that I love their products. They're a great way of making arrangers do more than they were originally designed to do.

The BK-7m and E-80 were designed for use with the FC-7. Stupid of Roland to discontinue it. They are sometimes available on eBay, etc. If you can figure out what the DIN connector is called, you can easily adapt a Ketron FS6 or make your own. That's really the best way of doing what you're trying to do. My $.02.

I would like to hear a clearer description of what you are trying to achieve…

Do you wish to combine the two engines, and do styles that are combination of both arrangers’ parts? Do you wish to use the lead sounds of the module with the styles of the keyboard arranger? Or vice versa?

I am a little perplexed about the choice of the two arrangers, as a BK-7m shares almost the same soundset as the E80. What exactly is the reason for trying to use both? Under the circumstances, isn’t the BK-7m a little redundant?
