2814.0. "YAMAHA QY10: misinterpreted sequences in pattern mode" by VARESE::FRANZONI (Blue like a Blues) Thu Jan 09 1992 08:30

To the moderator:
Sorry if I start a new QY10 note but at least 30 out of 53 replies to note 2558
are totally unrelated ...
Feel free to move this note, but in this case please consider to clean a little
2558 as well.
Thanks

To everybody (expecially to QY10 owners):

I'm still happy with my QY10 but it looks like it's depleting itself:

I already asked, in 2558, if anyother qy10 owner could notice a sound (sample)
difference in playing piano between 2nd and 3rd octave ... differences are now
getting louder (or are my ears getting finer ;-) and noticeable on other
voices as well ...

Then I discovered some bug in the pattern execution:

I wanted to transpose 5 half-tones up a song, I used the transpose function
available in the pattern menu, starting with the bass part, but then it
played wrong the last 4-5 notes.
I thought there was an error in transposition and edited the pattern that
sounded fine (all the note were transposed correctly !)

Transposing back 5 half-tones down, it turned to play fine again.
So far, I put the patter on a track (put function), switched to song mode,
used the song mode transpose function and it played fine !!!

I discovered a similar behaviour with percussion: I had a pattern with drum
and percussion beats in the drum track (pattern mode).
I wanted to split drum and percussion in two different track so I copied the
pattern to Chord I and edited to delete the drum notes ... well, what it
sounded like a hi-timbales now plays as a closed hi-hat !!!

What I figured so far is that there is some sequence of notes (note that
drum beats are internally stored as notes) that is misinterpreted when
played in pattern mode.

(note that everything is fine if the tranposition or the split is done
on a sequencer (I'm using Amiga2000 with KCS II) and the QY10 is used
as an expander.

I hope my qy10 is broken and can be replaced (still on warranty) ...
does anybody noticed some odd behaviors on his own QY10 ?

I've not the sequence here ... but if anyone wants to try it (I would
appreciate it a lot) please mail me, and I'll send you the sequence.

Thanks, Mauro.

2814.1	Possible problem with reharmonization?	ATIS01::ASHFORTH		`Thu Jan 09 1992 08:44`	15
	Mauro- Could this be a problem with the QY10's reharmonization of your pattern? I have to say that I found the (tiny) comments on that in the manual quite puzzling. If your symptom only happens on your own patterns and not the builtins, I'd guess this is a good possibility. What I've been meaning to do (but haven't yet) is to dump some of the builtin patterns to my sequencer (Bars and Pipes pro on my Amiga) and try to infer the rules from looking at them. (One thing I hate is the inability to "read" the notes in either songs or patterns!) Your note could be just the excuse I need to solve this riddle... Bob

	One sure way to NOT get this note (or similar ones) moved to similar ones is to make it unique. Since this note seems to address a specific problem with the QY10 it should stand on it's own, apart from "general" discussion of the unit. The base-noter can and should modify the title to reflect the specific problem, enabling future noters to find it easily. "Buggy or broken" could mean anything, inviting others to post other bugs which would dilute this conversation. Edd

	> Could this be a problem with the QY10's reharmonization of your pattern? I have >to say that I found the (tiny) comments on that in the manual quite puzzling. If I'm actually rising the tone and not changing the key armour (number of flats or sharp). I also tried to re-enter it with (manually) transposed notes ... same results.

	SWAG on the drum problem... It's not unusual for sequencers to IGNORE a drum track when doing transpositions, in order to avoid the exact thing you describe. A snare is a snare whether the song is in E or Gb. By moving the drums to some other track, the sequencer treats them as just regular notes and transposes them. Edd

	> By moving the drums to some other track, the sequencer treats them as > just regular notes and transposes them. for the drum problem I used no transposition, I just spiltted the part in two patterns ... all the beats sounds normally except one timbales beat that's interpreted as closed hi-hat ... Of course, a transpose on a chord track would have changed all the sounds. Actually transposition is not that much related ... it seems the sequence of notes to cause the problem (and after transposition it seems I've got that sequence). Cheers, Mauro.
2814.6		PAULUS::BAUER	Richard - ISE L10N Center Frankfurt	`Fri Jan 10 1992 05:33`	12
	Hi ! I'm not too sure if the following is related to the problem, but maybe. There's a built in feature that some consider is a bug (ok, we have these discussions with our customers too), which is that patterns should be entered in the key of C, then the transposition should work ok. The argument is, that this allows it to use the patterb with any song in any key. hope that helps Richard

The argument is, that >this allows it to use the patterb with any song in any key. that's for re-harmonization (i.e. change of key armour) ... transpose is slightly different. Than I've problem with the bass part as well (i.e. no chord) Thanks, Mauro.
2814.8	B-flat played as C	VARESE::FRANZONI	Blue like a Blues	`Mon Jan 13 1992 04:00`	18
	I traced down the problem during the weekend and discovered that it's not a sequence but just a note that is misinterpreted and transposition is totally unrelated: In pattern mode, all the B-flat notes in the Chord-I, Chord-II and Bass tracks are played as the higher C note on my qy10. If voice is drum (yet on the CI CII or bass track) the hi-timbales/ride will be played as shaker/open-hi-hat (pieces assigned to Bb and C). Everything is ok for tracks 1-4 (song mode) and drum track, the note is played correctly in edit mode and in keyboard mode as well. Since this would take only 5 minutes (and a free pattern) to test, can you (qy10 owners) verify if your units play the correct B-flat note while playing a pattern ?. Thanks & Cheers, Mauro.
2814.9	on repair	VARESE::FRANZONI	Blue like a Blues	`Fri Jan 24 1992 04:09`	5
	I brought my qy10 to yamaha field service for repair, they didn't know of any other unit with the same problem - it should be fixed on within monday, I'll let you know. Mauro.
