Today I reloaded the OS3.0c !!

The polyphony problems made me wanting the previous OS back in my SD1.
This is realy sad because I hoped Ketron would release a fix to repair the bad programmed version 4.0x's.......

Just curious : Who of the SD1 owners did downgrade too ?? (please reply this thread)

Roel

I have not YET, but becoming more frustrated every day. Hoping to hear something soon from AJ on this, otherwise I'll do the same.

IMPORTANT QUESTION...

The problem I have is with intermittant latency... is this the same as the polyphony problem? I occurs when playing piano over many of the standard SD1 patterns.

I was eager to use new styles and functions of Rel. 4.0, but I couldn't stand the notes being dropped out and cut off. I installed 3.0 back very soon after 4.0b was released.
I still hope, Ketron will do something about it!
Luka

Glenn & Luka,

Both the latency and drop-outs made me decide to go back.
I think Ketron software engineers took too much processor-time for the new sounds. The Grand probably takes 3 or 4 layered sounds ? This is why the CPU needs a lot of time to switch on a key and the max of 64 voices is reached.

Version 3.0c still has a (much smaller) latency but NO drop-outs.... what is very important for me

It's great to see replies on this forum. I put a similar post on a german forum..... and they try to tell me there is not a problem at all Perhaps only 1-finger 'musicians' ??

I still hope Ketron solves this very soon. (OS4.0c ?)

Acht du lieber, nicht gut! Let's clue in our German friends so they too can help communicate with Ketron.

I remember at least five more guys writing of the same problem, one of them looking for Rel. 3.0c.
What I secretly believe is that optimization of sounds for existing hardware is a lot of work to do and that silence of Ketron means they already work on surprise OS!
They are a factory that listens to customers!
Luka

Last night I tried the 'upgrade without new sounds' ..... and I must say it seems to work without dropouts
(I think Dan01 mentioned this earlier)

The sounds are not as 'thick' as in the full OS4.0b but this saves the so needed voices.

This will do for the time being I guess ?

Roel

Roel,
I tried this possibility also, but as I remember it was not much better. I am curious how it will work for you.

Hi Luka,

Now I remember you wrote a message about not better results. Are you sure you did NOT use the new sounds !
In my case I did a full downgrade to OS3.0c and after that followed the instructions on the Ketron webpage. (On a few points the SD1 behaved not as in the manual)

I played (and 'teased') the SD1 and .... NO dropouts in the Bass.

Perhaps you can give it another try ?

Andrea... What are your views on this?

Dan... Perhaps you can get a feel from AJ as to if/when this problem might be resolved.

Roel,
I tested this combination starting from 4.0a.
I'm glad you have good experience with it, maybe I should try it again.

Nevertheles, I still hope on some info about new, polyphony optimized OS.

Sorry the delay.
I already installed all the options that Ketron supplied with upgrade 4.0b. I tried all the possibilities and I like none.
IMO the option 3.0c still is the best option for the polyphony problem.
Recently I bought a 9000Pro and is very good to play without polyphony and latency problems.
I´m almost changing my nickname!!!
Like Luka, I still hope Ketron will do something about it.

Armando

Glenn,
I am sorry but I have to confess that I sold my SD1 (and my XD3 too).
Right now I am playing the 9000 pro and the Tyros and am very happy with them both; I really wish that Ketron could solve all the problems mentioned in this and other threads, but I guess that we'll have to wait the new model (due out next spring) to see how it works.
Compared with the SD1, the Tyros has:
- similar or better styles
- much better sounds (no noise whatsoever, with real studio quality and crystal clear high frequencies)
- much better OS
- much more friendly and intuitive interface
- better hardware quality.
I still hope that Ketron will surprise me in the future but for now...I put my money where the best value is.
Sorry guys...

Andrea,

This is a little surprise indeed ! Congrats with your new baby's.

I myself did a few 'test-rides' on the Tyros and missed a musical drive in the styles.
Perhaps it takes more time to discover the drive. I must admit the latency (in 3.x and 4.x) and dropouts (in 4.0b) generates a little more irritation every day (:-((

Ketron : You 'd better hurry with solving the problems

Roel,
when you play the Tyros you have first to set the Equalizer and the compressor to the right values; then you have to try the styles together with the multipads, which add a lot of realism: they work like the Ketron sampled grooves but the sound quality is much better (all the sounds are sampled at 44 kHz or more). I advice you to try all the "Ballad" styles and -if you think that the Tyros lacks drive- try also the "Dance" styles, but first press the "OTS link" button, to hear each style with his pre-programmed sounds...then you will tell me

AJ...

We definitely need some input from you (or someone from Ketron) on this, or more specifically, some reassurance that help is on it's way. Otherwise, Andrea will not be the last to jump ship.

If all I hear is silence, it tells me that help is NOT on the way. I hope that's not the case, because in many ways, the SD1 is a great KB, but this is a SERIOUS problem.

Andrea... sorry to hear that, but I can relate. I'd consider the Yammy route, but I need 76 keys and the 9000 is too heavy for transport. I'll wait a little longer, then I'll also be looking elsewhere.

I hope Ketron does not intend to overcome this problem by making a new keyboard
If I was Ketron, I would first finish the old work, solve this last significant problem in best possible way, and after that launch something new.

Weird !

Last night I decided to allow OS4.0b another chance. OS4.0b sounds/styles are much better !

I did the complete Upgrade including some renewed bonus styles as offered by Ketron on the www.ketron.it website.

Guess what :
NO delays (latency) ...... NO (bass)dropouts.... NO problems at all ?!

Now I'm starting to think the fresh installed OS4.0b is OK, but problems are introduced after a lot of (disk)styles are pre-loaded in memory ?
(The described problems sneeked in slowly and got worse every day as far as I remember, or am I wrong ?)

For now I'm happy again.

Roel

Hi Roel

Interesting test! Since I have also a couple of dropouts I would be interested in further ideas. Does it happen with the additional commercial styles only, or also with own edited ones? I edited a couple of internal styles and load them permanently into memory. Since I only work with registries the edited styles don't need to be permanently in the memory. It takes a fraction of a second only to load them upon calling a new registry.

I'm quite interested if you come to further findings.

En schöne Sunntig!
Hansruedi

Hall Hansruedi,

They happened with all styles, where especially strings were 'involved'. I had the impression the strings-sustain was way too long, so they kept the available voices for themselves. Because of this, sometimes the bass-voice muted and especially the Grand-piano showed pretty long latency.

Something 'consumed' voices and did not release them in time !? Another possibilty is a kind of internal MIDI-feedback loop ?

As I said, now the problem has vanished. I cannot reproduce the earlier problems and believe me I tried SOO hard

I did send mr. Sandro (Ketron) a copy of my experiences. (This might help while trouble shooting)

Roel

Another SD1 user just mailed me, telling his SD1 is working fine after a new OS4.0b reload.

Good news for other users ?!
Please write your experiences on this forum or directly to me.

I remember one (but perhaps important) fact of my SD1 after my first attempt to upgrade to OS4.0b : The rave-sound (pad group) did not sound OK because the sample was not correctly looped.... the end was not well fitted to the beginning.
Mr. Sandro sent me a fix, but I forgot to use it because I never use the sound.
Please check your RAVE !

Friends.

I have been reading your posts with regards to the note drop out but I am very glad indeed that Roel did make a break through.

Looking back at some of the variation we did between OS 3.0c and 4.0, we instead INCREASED the number of polyphony and so since this problem was brought up on the forum, I have been trying to reconstruct the problem on the keyboard and failed (even when I use the specific examples mentioned above). It's only when I say press 8-9 keys using heavily-noted program voices (like STRINGS) that I do notice some drop out.

Given the situation above, I would advise that all who are experiencing this reload the OS4.0 a/b - sometimes during download, it is possible that some of the binary files in the OS were mis-transfered. Hopefully on the 2nd try, this doesn't happen.

Thanks,

AJ

Roel,
where the heck did you find the energy and will to test the impossible!?
This is great news. If it is errors in download as A.J. suggests, than it seems like problem is gone

Roel,

I had already made this installation at least some twice !!!
Saturday I did again an OS4.0b´s complete download and install again all the files at folder Standard ….
After a new reload (OS3.0b to Os4.0b) my SD1 is working fine,even using the harmony function.

That is a mistery of computer programs.

Armando

I work in the computer world, and when you are create an new version of a software, you must create a program to update old versions... I think there is a bug in the Update in the SD1 from the 3.0 to 4.0a, and the 4.0b don't fix this bug (if you only install the upgrade). You must reinstall the 4.0b entierely with all disks...
This is just a supposition... I m not sure ...

Voilà.

After I have done that, my SD1 work´s fine.

DAN2000 :
You probably are very right !!
I'm in computing too and that is why I don't think errors occurred in file transfers either.
If they would have happened there is NO chance at all it would cause the same 'defects' with similar symptoms in these different SD1's.

It's great to read that you all 'repaired' your SD1's !

Yes, this is great…and I feel great…I new Ketron would not let us down!!
This is the nicest gift for my 2nd anniversary with SD1!!
