QY20

Unread post by Exo » Mon Feb 01, 2010 9:52 pm

Hi everyone,

One of the yamaha products I have is a small QY20 arranger.
When I want to control it using a midi sequencer (Fruity Loops on my computer), something strange happens...

Here's the setup :
- Computer midi out into midi 3 in of the Roland A-880 midi patcher
- A-880 out 3 to Yamaha TG77 (midi receive channel is set to 11)
- A-880 out 4 to Akai SG01V (midi receive channel is set to 2)
- A-880 out 5 to Oberheim Matrix 1000 (midi receive channel is set to 3)
- A-880 out 6 to Yamaha QY20

The problem is : The QY20 is ALWAYS playing together with any other connected device I play ...

It's like I am not able to give the QY20 a midi receive channel. All the others play independently but the QY20 is the only one who ALWAYS plays along... :x

Any of you guys who might have a clue? :roll:

Thanks in advance!
Exo.

Your owner's manual is your friend, you should always check there first if you are not familar with all of a devices functions/parameters. See page 162 of the QY20 Owner's Manual, Utility Functions, PGC Mode - Program Change Table Mode which explains midi channel setups.

Hi Clyde,

Indeed you're right about checking out your manual first but... (that's what I have done) but still, there seems to be something wrong ...
Putting all the other modules on channel 11,12,13,14... QY20 still plays along with the others .... and changes its patches when I change patches of one of the others ...
The problem remains the same ... :?

I've skimmed through the entire QY20 manual on the Yamaha Manual Download page, the settings available on the QY20 are rather limited. Try recording something that only has data on channels 11-16 and see what you get. The patch changes for another module I take it are transmitted via midi. I'm not sure what will work for you with the QY20 settings being limited (though I agree that somethging seems to not be working correctly at the moment). Page 161 try setting Device # to "off", page 169 PGC Mode Normal/GM try setting to Normal. I'll look around a little more and see if I come up with anything that applies.

One other thing, I see in your first post that the Akai is set to ch2 and the Oberheim is set to ch3, both ch2 and ch3 will play QY20 sounds as they fall within the QY20 ch1-7 + ch10 voice assignments. You will need to set both the Akai and the Oberheim to something between ch12-16 as the TG77 is on ch11.

From the Yamaha Knowledgebase"

"Sequencer Track MIDI Transmit Channel assignments on a QY20
The QY20 has 8 Sequencer tracks that are assigned an unique MIDI Transmit Channel. (See table below)
Sequencer Track 1 - midi Ch. 1, Track 2 - midi Ch. 2, Track3 - midi Ch. 3, Track 4 - midi Ch. 4, Chord1 (CH1) - midi Ch. 5, Chord 2 (CH2) - midi Ch. 6, Bass (BS) - midi Ch. 7, Rhythm (RT) - midi Ch. 10.


NOTE: The assignment information is ONLY relevant when transmitting MIDI data to another MIDI device."

The key statement to me here is that the assignments are only relevant for transmitting midi data, to me that says it does not apply to receiving midi data which to me would be a device flaw.

OK, I've just finished reading dozens of user reviews on several sites, none of them mentioned any issues like the one you are having. I'm starting to think it is either your midi channel assignments, a one off fault, or a midi loop in your setup. Let us know what you find out.

QY20

Unread post by Exo » Thu Feb 04, 2010 4:08 pm

Hi Clyde,

I tried lots of combinations but the QY20 ALWAYS plays along...
2 things in the manual attract my attention ...

Page 162 is the list of midi channels on which the QY20 will respond.
This same list is also found on page 22 but with an additional Detail comment :
Data received on MIDI channels other than those listed above also produce
sound, according to the selected “Pgc Mode” (page 162) and received MIDI
program change messages (see the “MIDI Data Format” booklet).


I made the most simple setup and connected the Midi out of my soundcard (EMU0404) to the Midi in of the QY20.
Page 160 says : "Midi Ctl : This parameter simply turns MIDI control of the QY20 on or off. “On”
is the normal setting, and with this setting the QY20 receives note, program
change, and control change data from an external MIDI keyboard or
other controlling device. Transmission and reception of start, stop, and
continue commands is also active, as is MIDI clock transmission.
When set to “Off” the QY20 will not respond to external MIDI control."
Even with Midi Ctl OFF it continues to play ! Not the sequencer part, that doesn't react anymore but when I hit the keyboard, I hear sound...
No matter what midi output channel I select in the Fruity Loops created midi instrument, QY20 always plays ...
I'm starting to get paranoid .... :?:
In the Pattern section, QY20 reacts also on every midi channel. I can see Accompaning channel1 and 2 as well as the channels for bass and drum patches change as I change the patch of the specified midi channel (5,6,7 or 10). I even hear sound altough these channels in the Pattern section are muted !

So, to make this long story a bit shorter, QY20 reacts on everything you give it except for the sequencer that doesn't react when Midi Ctl parameter is set to off.

Perhaps, the only thing that might influence the on/off status of a midi channel of the QY20 is to put it on/off by Sysex messages.
Altough, I must say, I'm not an expert in this matter, for not to say that I'm a complete newbee on this.
I have the Midi Data Format booklet so that might help ...

Luckilly, I am a very patient person ... (but there's a limit on everything! 8O )

That does not sound like normal behavior, I would also double check ALL settings in Fruity Loops. You could also do a test by hooking up a controller keyboard directly to the QY20 (and I mean directly, no computer, no software, no other synths, just a controller, the QY20 and a cable) and see if the results are the same, if they are then it would seem that it is a QY20 issue, if the results are different then it is not the QY20 but elsewhere in your setup. That is the same way I had to troubleshoot midi issues years ago when my setups often caused issues, at least then you will have a better idea of where the issue really comes from.

I think that it must be something with the QY20 too...
This weekend, I will connect it directly to my master-midi keyboard (CME - UF8)
I keep you informed!

The QY20 is put to rest... My opinion, there must be a bug somewhere...
In the meantime, I have a problem with a setup containing 2 RM1Xs but I'll post this in another topic.

Thanks Clyde!

I've got one of these kicking around somewhere..

I'm pretty sure it receives on all 16 MIDI channels, and can't be set to just one receive channel.
You could try 'muting' the channels you don't want the QY20 to play on form the mixer page, but I'm note sure if when it receives a MIDI program change message it will unmute itself.

Perhaps it's time to invest in a MIDI interface on your computer that has more than one MIDI out?
That way the QY20 can have it's own MIDI port, and you can decide what parts are played from Fruity Loops, and some of your other modules could be used multi-timbrally too.

As a workaround, in each Voice there is a patch above all the drumkits that's called "Off" and produces no sound. Maybe that will help?
