For better or worse, there's an 0.053-pre3 on
<http://www.graggrag.com/?q=yoshimi>.
The settings corruption seems fixed, and some stray chaos from the recorder
reorg seems to be under control.
In the vague hope that it might help when I stuff things up, I've put up an
0.053-pre2-0.053-pre3.diff as well.
cheers, Cal

A quick test indeed shows that my "yoshimi not remembering my bank

Well, for what it's worth, here on a non-RT kernel but with RTPRIO set
properly in limits.conf, using jackdmp 1.9.2:

These are rather low. I just looked, and yoshi tries for 55, so these settings

in MusicIO.cpp line 214 down to your level and see if that helps.

Interesting difference between Zyn and Yoshimi here. Zyn has a Reverb

high priority? I thought the common case was to run jack a lot higher

No. Torben's tip resolves the issue in 0.053.2, which uses whatever jack
says it should use if that's lower than 50, otherwise it goes for 50.
How that's going to go on the alsa threads is still a wonder.

It's a proper high speed USB2 hub that claims to be compatible with
USB1.1. I have a USB2 scanner hooked up through it, and when I scan
high-res 24-bit color, it scans at USB2 speeds. Having accidentally used
it ONCE on a different machine that had only USB 1.1 ports, I *know* the
speed difference! ;-)
Have you tried it without the hub?
Not yet. I plan to.

I think jackd kicks yoshi off, because it consumes too much time
in the rt-process then, although this doesn't really explain why it doesn't
happen with 038 that fast.
It just saw it with 038 too. Yoshi stopped for a moment,
but did not get disconnected from jackd, instead jackd reported some xruns.
I'm playing with a latency of 8ms, btw., at a rate of 48000.
A question pops up:
Which would be the most appropriate behavior,
when running out of time in the process thread ?
Stop processing voices ?
Process them, allowing to xrun ? No, I think.
Process them, but disconnect from jack ? No, I think.
Any other options ?

I don't know if this is known:
Yoshimi 054 pre2 and pre4 both disconnect from jack, when pressing
many keys (~10) at the same time on my midi keyboard.
This does not happen with yoshimi 038
Cant repeat that here. Are you using jack-midi or alsa-midi? I'm using
alsa-midi.
I can stick both arms down flat across the keyboard without it
disconnecting - get rather a lot of xruns though!

Sorry to be late to this little party, but that's timezones for you ...

That's one of my standard QA tests, perhaps the only standard QA test I
regularly apply. Xruns I get, disconnects I don't.
I've connected the keyboard through jack-midi to
yoshimi.
I think jackd kicks yoshi off, because it consumes too much time
in the rt-process then, although this doesn't really explain why it doesn't
happen with 038 that fast.
That's puzzling, almost interesting. The main differences from 0.038 that I can
think of are a switch to pthread_create managing the priority setting on the
audio/midi threads, and some refinements to the locking when changes to parameter
controls are in progress. At face value
It just saw it with 038 too. Yoshi stopped for a
moment,
but did not get disconnected from jackd, instead jackd reported some xruns.
I'm playing with a latency of 8ms, btw., at a rate of 48000.
A question pops up:
Which would be the most appropriate behavior,
when running out of time in the process thread ?
Stop processing voices ?
Process them, allowing to xrun ? No, I think.
Process them, but disconnect from jack ? No, I think.
Any other options ?
A total rewrite of the synth? Sorry, not this little black duck!!
What we've got so far is a rewrite of the audio/midi drivers, but the core
synth engine remains as was apart from a few relatively minor efficiency/
performance refinements.
The concept of a wall clock for the process callback to keep a check on is
interesting (I have thought about it). Given the structure of
Master::MasterAudio(), your rule selection candidates don't really fit
what's currently going on in there, which brings us back to the total
rewrite question.
Since the wall clock thing has come up, one thing I am curious about is the
timing of the midi notes. At present, you can't have a note-on/note-off during
the generation of a buffer full of audio.
I'm inclined to agree with Will, that the cause of your grief seems more to do
with general midi issues rather than yoshi specific ones, though I will have
a think about the 038 -> 054-pre differences.
cheers, Cal

Yes.
In the terminal there is this message:
Info, alsa midi port connected
Jack reports error: jack_client_thread zombified - exiting from JACK
Too may notes - notes > poliphony, PartNoteOn()
Too may notes - notes > poliphony, PartNoteOn()
Now - that's strange:
I found it happens with 038 too.
and:
It seems to depend on the instrument used:
The default sine-like tone doesn't cause an error,
but when using Rhodes/SynthRhodes2, pressing two keys at once
zombifies the jack process.
Is this reproducable?
Maybe one of the internal synths/effects is still not rt-safe.

Looks to me like a straight deadlock, ie a lower level section waiting on a lock
while the lock is already held by it's caller. I'll work on it.

And I believe you are quite right. In messing with the deadlock issue on
parameter save (0.054-pre4 only) I got all kinds of things confused. In
fact I can _not_ replicate the reported issue on Rhodes/SynthRhodes2 (or any
other instrument). The forearm test and the "two keys simultaneously" both
test fine for me ... well, as well as the forearm test ever does.
It's been a muddled couple of days here.

Hm.
I installed a recent version of jack (jack2).
Now it doesn't disconnect from jack anymore, when playing SynthRhodes2,
but it causes xruns, and quite audible distortion
when pressing ~3 keys at the same time.
There must be missing anything.
It's been a muddled couple of days here.
Take a break, Cal. Re-think
it after some days.
Thanks for the efforts.

Yep, that'd be nice. Can't promise I'll actually take it on, but ideas on

get motivated to try it.

I've been wondering where the 'last bank' recall went to too. I'll look

Excellent. I think it really was just you & me that wanted the record facility,

Hi Cal,
I just tried 0.053-pre3 very briefly and found one bug.
On the bottom of the main window there's a meter and next to it the
value in dB. It seems that the channels are at least turned around, so
when it goes into clipping on one channel the meter on the other channel
is somewhere near where 0dB probably is (which is also not very clear to
me..).
I found this with a patch that produces quite different levels on both
channels, 'Choir and Voice' -> 'Vocal Morph *'
I don't understand that meter, I guess the blue bar is peak, the yellow
one rms, but I don't know whether 0dB is at the right end of the meter
or at the thicker line before it. I also don't know whether the numbers
correspond to rms or peak.
Well, just thought I let you know :)
Yoshi is already quite different from zyn imho, and not worse, despite
the one or the other quirk. And most importantly: it's worked on, so it
has potential for improvement.
Regards,
Philipp

To be honest, I don't understand the meter all that well either. Last time
I messed with it, I stuffed it completely so very quickly put it back the
way it was. The bluish bar is a calculated "dB", and the yellow line is rms.
From a quick look at the code and watching Vocal Morph
in action, I suspect
you might be right - it does appear the peak indicators might
be transposed.
But then it's 4am and I can't sleep, so now's not the time for me to be
messing with code (even "simple" code).
Well, just thought I let you know :)

Appreciated. It is a strange beast, invoking strange relationships.
