Sheet Music: app.box.com/s/...
Performance Memory: app.box.com/s/...
By downloading the sheet music and accompaniment (performance memory), you can play this song using your V-Accordion and BK-7m exactly as I do. Using your computer, copy the "Roxy's Demo.UPS" file to the "My Performances" folder on a USB memory stick that has been previously formatted on your BK-7m. Then plug the memory stick into your BK, press the "Performance List" button, load the "Roxy's Demo" list, and select the "001 Dreamsong 1" performance memory. You're ready to play.
I am using treble tones on the BK-7m. So turn the volume of your V-Accordion to zero (minimum). Also, for you to be able to play these tones with bellows action, as you see me do here, you must adjust the MIDI parameters of your V-Accordion appropriately:
Bellows Expression Tx = On
Velocity Tx = 127
Bellows TX Resolution = Max resolution (number value depends on V-Accordion model).
On an FR-7x you may prefer to specify "Velocity Tx" at the BK as follows:
UP1:
[Menu]-[MIDI] -[MIDI Set: User1]-[Edit Tone Parts]-[UP1]-[RxVelocity: 127]
UP2:
[Menu]-[MIDI] -[MIDI Set: User1]-[Edit Tone Parts]-[UP2]-[RxVelocity: 127]
Enjoy.
Thanks Leon, Your advice is always very valuable. Luis
once again.. another great instruction video from Leon... and thanks for the sheet music.. I'm printing and heading down to the studio to play..
thanks
Very nice videos you are making. Thanks. I'm using Performance Next. Now how do I create a play list. Or how do I move around the performances for songs into different groups for different gigs so I can then use Performance Next to move from song to song. I know I could create a new Performance list and copy the song performance into the new group, using the turn wheel, but that is tedious. Is there another way?
I might suggest not selecting 127, but maybe 126 or a bit lower... For some MIDI voices played on the BK-7m if you have it set to 127 it triggers certain effects, like a string pluck or pitch bend which you wouldn't want all the time. If you don't want to use the velocity of the keyboard to trigger it, and don't want it triggered for every note, you have to set the TX Velocity lower than 127.
How sure are you about this? The BK's interpretation of the Key Velocity parameter is different for a V-Accordion than it is for a keyboard. When setting Key Velocity to 127 and when using a V-Accordion with with"Bellows Expression" turned on, the actual Key Velocity that the BK associates with each note is a value between 0 and 127 (or in your case 126), depending on the force applied to the bellows. This is obviously true since if you press keys without using the bellows you get no sound. To achieve an actual Key Velocity of 127, one would have to push and pull the bellows very hard indeed. So, when playing normally, the BK will associate some midrange value of Key Velocity to each note pressed in accordance to the pressure on the bellows at that time. Although I am not saying that the effect you refer to does not exist, I have never noticed it, and if it is true I suspect that when using a V-Accordion it would only occur when you pushed and pulled the bellows extremely hard. Another factor here is whether or not you adjust the key velocity at the V-Accordion or at the BK. If set at the V-Accordion, in which case the Key Velocity of the BK remains set to "ON", then the BK is not even involved in the interpretation of the Key Velocity of each note played. The BK simply receives MIDI note messages containing a Key Velocity value in the same manner as it does when the controlling instrument is a keyboard. In that situation, it is my understanding that the BK has no knowledge that the Key Velocity parameter of the V-Accordion has even been set to a fixed value. It received notes exactly the same as it would when using a keyboard, Key Velocity values that correspond to how hard or how softly one presses the keys, only in the case of the V-Accordion those Key Velocity values are in accordance to bellows pressure. The bottom line is, in your case the dynamic range of the BK would be 0 to 126, in my case 0 to 127, which I doubt anyone could even notice. Still, what you say may play some kind of a roll that I am unaware of, which is why I ask, "How sure are you about this? Can you actually perceive a difference when playing music at normal levels? Have you actually played using a V-Accordion (not a keyboard) with Key Velocity set the way we at Roxy's recommend, and have you then perceived an audible difference when playing at normal bellows pressure compared to setting it the way you recommend? I tried it and I cannot.
@@RoxysMusicStore RoxysMusicStore I wouldn't have bothered to come here and write it if I hadn't just experienced it first hand after following your instructions. I don't remember which stringed voice it was, but it induced a harsh plucked effect with a bit of a string bending sound. Dropping velocity a bit on the v-accordion removed it. I have run into that in the past, it is not unique to the v-accordion, it is how some midi players, like the bk7m, can interpret maximum velocity to give you a different effect on an instrument if you really hammer a key.
RoxysMusicStore By the way, are you sure about the interaction of bellows and velocity? I don’t believe so, but I don’t have time right now to hook up the accordion to a computer to monitor the midi data. Expression is a separate midi event, as is volume, and they are for different purposes than velocity. Velocity in midi is not meant to control volume, but for attack. The expression midi event adjusts volume, but does not alter the velocity. There is also a separate midi volume event. The midi player takes all three into account as to how loud I plays and the note dynamics. RoxysMusicStore
@@stevenpalm9484 Well, you got my curiosity on this one. So, using an FR-3x as a controlling instrument, with the Key Velocity adjusted on the 3x to either 126 or 127, and leaving the Key Velocity on the BK-7m at it's original default setting of "ON", I auditioned all sounds in the "Strings" family on UP1, each time once with an FR-3x Key Velocity parameter set to 127, then immediately following a second time set to 126. It was easy to do on the 3x in "Parameter Mode" by pressing the #1 and #2 register buttons. The display indicated 126 and 127 accordingly. I noticed no perceptable difference in any of the sounds. Sorry. What you say about how these messages can be interpreted on different systems may be true. I wouldn't know. But it seems to me that since the Key Velocity is being set at the V-Accordion, leaving the Key Velocity at the BK-7m at its original value of "ON", and because the BK-7m is responding to bellows control, then whatever messages it is receiving must be the very same as it receives from a keyboard where the BK responds to how hard or how softly one presses the keys. I don't know that for sure, but my intuition tells me that that is true. I agree that it would be a good academic exercise to connect the accordion to a midi monitor, but I don't have time to do that. If you ever do, please report what you find.
Thee same effect on Ac.Guitar1 (and possibly other voices) happens if I set the BK-7m velociy on that part to 127 instead of having the V-Accordion transmit it that way.
