MB SID freezes when "flooded" with midi

kokoon · September 3, 2005

i put flooded in quotes because i don't think it's really a flood.

if i twiddle a knob on a midi controller too furiously i get the whole thing to stop responding. last note plays on and nothing changes. have to turn it off and back on.

since it's not like 10000000 midi CC messages per second i'm assuming something is wrong.

now my question would be - is this supposed behaviour? will it be the same with the cs?

thanks guys, i just built a mbsid and i LOVE it. but this really bothers me.

hi!

IÂ´ve got a MBSID with minimal CS,.... and I have this problem only a few times... if IÂ´m carefull and send only the MIDI-Data SID really needs, thereÂ´s no problem....

Perhaps itÂ´s normal to have a MIDI-hang (sorry, donÂ´t know the right word in English) sometimes..... I think itÂ´s the same with some analog-synths,... sometimes..... Please tell me if IÂ´m wrong!!!

hope this helps,..

pwx :)

I don't know this effect, maybe because I'm working with a much more advanced firmware since some months?

Are you using the most recent version of MIOS and MBSID?

Hi Thorsten!

IÂ´m using MIOS 1.7,.....Â :) but itÂ´s really no problem,... IÂ´ve got the same with my Fricke mfb synth 2 ..... one or two times in a whole year,.... and the same with MBSID,... so this should be a `normal` Hardware Problem,...Â ;D

I donÂ´t care about it....... , every hardware Synth has itÂ´s own personallity :o

But IÂ´ll try MIOS v1.8 next week.....

greets,

pwx

The difference between MIOS V1.8 and V1.7 isn't so big, so this is not the reason. There was a problem with MIOS V1.6, which is fixed in both versions.

Testing the updated MBSID application makes more sense. I always take care that such MIDI overruns never happen, if you've found a way to hang up the MIDI engine, then please send me the appr. patch (but please: try it out with the most recent firmware first)

Best Regards, Thorsten.

i'm running MIOS 1.8 and SID 1.7a.

i'll try with the new SID app.

but - in short - what happened:

i have this M-AUDIO radium49 and it has a terribly slow pot readout refresh rate - if i turn a pot quickly i only get 5 or so values. even only 1 if i try really hard. so i made a patch in pd which interpolates incomming midi controller values so i can use my radium. the patch works fine. i thought until now :)

kokoon · September 5, 2005

okay i tested this with MIOS 1.8 and SID 1.7 303beta9

it's still happening but only with 8580. the second core+sid 6581 is okay. hmm if you want i can send you a screenshot of midiox out-monitor. but it's really not that interesting - just a few CC sends for filter cutoff...

kokoon · September 7, 2005

any ideas TK? i found out that i have to re-upload SID application everytime it freezes... and it also happens with pitchshifts (if there are many)... will this happen with the control surface too?

TK. · September 7, 2005

I wasn't able to reproduce the error yet, maybe it only happens at certain patches? Which patch are you using exactly?

Best Regards, Thorsten.

kokoon · September 7, 2005

just anything really. i uploaded mios, then uploaded sid (latest version) and i just press a key on my keyboard and send a stream of CCs... and i'm there.

is it possible that the sid chip is faulty? cause as it is now it really isn't very usable via midi. strange thing though - the jsynth tweaking is smooth enough and it never freezes. maybe jsynth works with sysex?

TK. · September 7, 2005

Yes, JSynthLib works with SysEx... the SID chip shouldn't cause such a problem, because there is no feedback to the core. Means: regardless if a SID is connected or not, the application should never freeze.

I've really no idea what should cause such a scenario, just let me some days, maybe I will be able to reproduce this sooner or later... if anybody else but kokoon and pwx is able to stimulate the hang-up, please let me know.

Best Regards, Thorsten.

tarzan boy · September 7, 2005

i just got my first 6581R2 running this morning and I have a similar problem I thought i would contribute to maybe help solve a potential problem.

I'm using mios 1.8 and sid1.7a as well, and using Jsynthlib (the only way i have right now of changing the sounds predictably) if I make some drastic changes in envelope, modulation matrix, or oscillation settings (transpose, etc) my sid starts to whine a high pitch in between every note. when i stop sending any midi data the high pitch just stays there. I have to use jsynthlib to reload a patch in order for the high pitch to stop.

kokoon · September 8, 2005

i don't think that's the same problem tarzan boy... mine freezes completely at the note it was playing and i have to turn it off and back on.

TK: if there's no feedback from the SID chip to core then is it maybe possible that the SID itself freezes? well it doesn't freeze completely since the osc's are still running... let me know what to prepare (sound sample of the freeze, screenshot of midiox output, ...) and i'll make it and send it to you (or post it here)

TK. · September 11, 2005

my sid starts to whine a high pitch in between every note. when i stop sending any midi data the high pitch just stays there.

thats a 6581 typical problem, see also http://www.midibox.org/forum/index.php?topic=5373.0

So, it seems that Kokoon is currently the only one who notice such problems...

TK: if there's no feedback from the SID chip to core then is it maybe possible that the SID itself freezes? well it doesn't freeze completely since the osc's are still running...

There is only one scenario where the SID oscillator can lock up, and this happens when noise is selected together with another waveforms. But this illegal mode is prevented by the MBSID firmware, and I'm very very sure that it cannot happen (I'm doing SID sound design very often, I should notify such errors...)

let me know what to prepare (sound sample of the freeze, screenshot of midiox output, ...) and i'll make it and send it to you (or post it here)

A sound sample and the MIDI input trace (via MIDI-Ox) could be interesting. Are you able to reproduce this problem with one of the default patches, or did you create a special patch?

Best Regards, Thorsten.

P.S.: I will be quite busy in the next weeks, therefore please forgive the high delays between the answers...

kokoon · September 12, 2005

i don't deal with "patches" (or at least i think i don't) - i can load the MBSID application and just run the sequencer and the freeze occurs. (as i just found out) - samples coming right now.

kokoon · September 12, 2005

okay this is what's happening:

i re-loaded the MBSID freshly. then i started the audio recording and cleared midi (output) monitor. then i played some random notes (TS 28712 - TS 34853) then i pressed "back" in midi sequencer (to reset to position zero - and apparently set all controlers to zero), pressed+released another note, and then started the sequencer. (TS 39775). it played almost a whole loop but then froze @ TS 40663 (bold). the "okay" notes are light color, the critical note is bolded black, the ignored are normal black.

here's an mp3 audio of this phenomenon.

TK. · September 12, 2005

Thats a very uncritical timing, I've still no explanation. Even if your MIDI interface sends an invalid MIDI frame (e.g. due to a slightly different baudrate, or spikes on the transmission line), the PIC should regognize this, it should set an error flag, which thereafter should lead to a MIDI timeout in MIOS.

Could you please try to reproduce this again? Thereafter use the RAM Readout function of MIOS Studio to dump out the RAM content from 0x000-0x600. Please also post the MIDI-Ox Logfile again. This should give me an overview of the system state, when this happens

Best Regards, Thorsten.

P.S.: your sequencer sends an "all notes off" (CC#123) when you stop it - thats bad for the MBSID, since CC#123 controls Parameter#3 of the wavetable sequencer. However, this is not the problem here... but maybe it's better to turn off (or filter out) this option to avoid interferences with the sound patch

kokoon · September 13, 2005

okay here goes.

now i seemed to have no problems with just the previously posted sequence of notes, so i had to add some CCs to the sequence. then it froze.

i didn't record it so i can't tell where exactly it happened but i turned the sequence almost immediately after SID froze.

Again: could you please create a RAM dump?

This is a problem which cannot be reproduced on another hardware, therefore the MIDI data alone doesn't help, regardless how long the log file is...

-> http://www.midibox.org/mios_studio/mios/gui/help/mios_debug_functions.html

SRAM Read, Address 0x000, No. Bytes 0x600

Best Regards, Thorsten.

Ok, what I've seen so far: the note stack for osc1

is located at 0x15c-0x15f:

0150: 00 00 00 00 00 00 00 00 1E 00 00 00 1E 00 00 00

The first position of the stack contains "1E", which means,

that note 1E = C-2 is played

Unfortunately the logfile doesn't show a Note Off... ok,

so let's assume that at this time the MIDI transfer

was already stucked. Let's search for more informations...

The MIDI In Buffer is located at 0x500-0x53f

0500: 00 00 7E 40 00 0D 02 00 00 00 00 06 00 00 00 00

0510: 00 00 F7 2F 35 B0 2F 35 B0 2F 35 B0 2F 35 B0 2F

0520: 35 B0 2F 35 B0 2F 35 B0 2F 34 B0 2F 34 B0 2F 34

0530: 80 24 00 90 1E 7F B0 2F 34 B0 2F 34 B0 2F 34 F0

The last received events before the SysEx Request (which

begins at 0x53f) are: 80 24 00 90 1E 7F B0 2F 34 B0 2F 34 B0 2F 34

80 24 00: thats a note-off message for F#2

90 1E 7F: thats a note-on message for C-2

B0 2F 34: thats CC#47, Dec-Value 52

F0 ...: SysEx message (RAM read) begins here

CC#47 (Resonance parameter) is a 4bit SID register,

it's located at 0x117, bit 4-7:

0110: 00 08 00 00 F0 03 06 61 1F 0A 00 BC 9D 00 01 02

bit 4-7 of 0x117 is: 6

The 4-bit value of the received CC#52 is: 52 >> 3 = 6

In other words: the last MIDI events which were

received by the MBSID are stored correctly. There is

an active C-2 note, can you confirm this?

Ok, lets search for the logfile entry where F#2/C-2 was

sent, and thereafter 3 times a CC#47 with value 52:

Hm... and here I have a problem: the last combination

I found was:

497465 2 -- 128 42 0 1 F# 2 Note Off

497466 2 -- 144 36 127 1 C 2 Note On

497468 2 -- 176 47 110 1 --- Control Change

497474 2 -- 176 47 110 1 --- Control Cha

CC#47 is 110, and not 52

So, I'm missing something in the logfile. Maybe this was

also lost... (there is a character limit in the forum)

but now you should know, which informations are interesting

for me: the events at exactly the point where the note gets stucked

However, another point: During the analysis I remembered that

a friend has a similar problem with his M-Audio Delta1010

Soundcard/MIDI Interface. Once a lot of MIDI traffic is sent

out, the interface stucks and he had to reboot his PC.

I don't want to say that you've exactly the same problem

(because of two things: you don't need to reboot your PC,

and you are still able to send SysEx data)... but driver bugs

are things which have to be considered.

Therefore not only an updated logfile (which shows the

interesting moment) could be useful, but also the results

of a loopback test.

You can do this in the following way: after the SID stucked,

enable the MIDI merger via MIOS-Studio (select the

MIOS_MIDI_MergerSet command and send WREG=0x01". Thereafter

send some notes to the core module and check if they are

received back. Do the same test after power-on of the

module (doublechecking)

If you don't receive any MIDI data back from the core

module when MIDI merger is enabled, you know that your

MIDI interface doesn't send any CC/Note values anymore

Another point: it could be, that sending a SysEx message

"resets" your MIDI interface. In this case following

additional tests would be interesting:

- enable MIDI merger via MIOS-Studio, thereafter try to

get the MBSID stucking again, thereafter check if

MBSID still returns the sent events (if not, you are

very sure that Notes/CCs are not sent by the MIDI

interface anymore)

- once MBSID doesn't react anymore, send a SysEx message

(e.g. MIDI Merger enable, or RAM read), and thereafter

send a Note-Off event of the note which got stuck. If

this works, then you know that a SysEx message resets

your MIDI interface... in this case I would say, that it

is definitely a bug in the driver of your interface

Any new inputs?

Best Regards, Thorsten.

hmm thanks alot for the in-depth comment and analysis. i'll try some more stuff tomorrow.

another thing that got lost 2 posts ago (got cut off) - is it possible that lack of midi-in gnd connection is the fault for all this?

is it possible that a hardware fault (a bad solder joint?) is causing such an error?

okay on to the point. there really isn't a F#2off C-2on and three times CC#47 value 52 in the stream, i've checked both output dump of midiox and input dump and there simply isn't such combo. i guess it's safe to assume that the core got something else than i was trying to send it (correct me if i'm wrong)

though there's a

496335 2 -- 128 36 0 1 C 2 Note Off
496335 2 -- 144 42 127 1 F# 2 Note On
496341 2 -- 176 47 52 1 --- Control Change
496341 2 -- 176 47 52 1 --- Control Change
496355 2 -- 176 47 52 1 --- Control Change

but from the looks of "80 24 00" and "90 1E 7F" i assume the last byte of each is velocity (first one is off and the second one is on-127) so i guess there's no mistake on your analysis :).

about the note C-2 being stuck - i'm really not sure... i remember it was something not too high and not too low so i guess it's pretty possible it was C-2. but not for sure. i'll record it all for the next test and i'll choose the test notes and controller values more carefully.

also - i'll try another midi interface i have (an M-AUDIO radium) and maybe i'll find out that one's okay... hmmm why the hell haven't i thought about that before?! actually it's quite possible that the ancient roland midi adapter i'm using mixes some stuff up!

i'll check it out in the morning and report back. i hope it wasn't such a stupid mistake :-[ :-[ :-[
