Reply with quote  Mark this post and the followings unread

I thought we better have an own thread to collect bugs or missing features that are known in 1.3 here to have them all together and allow easy reference for people that want to fix a problematic patch by hand...


So known bugs in 1.3 sofar:

1- morphs on switches go usually wrong because the G2 cant scale them

2- sometimes delay modulations cause distortions because you get longer delays on the G2 on mod values >127... a limiter module before the mod in set to 50 asym helps

This was the known...
Thats the new findings:


3- OSC A gets PW settings 1-50% wrong when no modulation input is applied in the Nm1 patch ( an optimization bug..model gets not applied )

4- Fozzie bug, sometimes a cable that is supposed to be red gets blue... (reason yet unknown...)

5- G2ian bug, DX2g2 Pitch EG Times are factor 10 to long (wrong table translation...)


...so.. sofar G2ian, Fozzie and me found a sofar overseen bug
who wants to join the competition?

please report your findings here... best by posting wrong conversion and original or the exact location and patchname where to find the problematic patch..

Its enough to point to patches that sound wrong
So even when you don't see what is going wrong or just get the idea that this cant be intended please report..

Thnx
sven

There's also the bug with author's names with special signs in them, like æ or ö. Since the author's name is automatically placed into the credit-text-modules, this results in a failing patch. On loadup, the editor gives an error message like "module with invalid name" and then the patch is silent. Delete the text module, make it recompile and it plays again.

I'm not sure I understand. There are no text modules in the NM1. Are you saying the name of any of the modules? I'll look into fixing this. Some sort of convertion table may be necessary. Python may have it already. It is suprising because those portions of the .pch2 file format have space to contain the characters.

I tried typing some ö õ à like stuff directly into module names in the G2 editor, it does not accpt such characters. So apparently it wants strict ASCII.

In the text block where your own credits are (which you insert on purpose after conversion) there is als a text module that shows the author name (probably from the directory it came from). As Blue Hell pointed out, you can't type these signs into the editor, so when your converter put 'em in automatically without the editor, the editor chokes on it upon patchload. Try to load any patch from the directory "Björk_Mikael" and see what happens. The text is all weird in the text module and you get an error warning (at least in the demo software, which I used for testing). I haven't tried, but I predict the same will happen with patches from Per Wikström. When you delete the offending text module out of the G2 patch and change variations (or possibly delete/add another module) the patch starts to work.

Some more clarification on the 'name' thingy:
qfingers wrote:

No, but the error message states something like "invalid module name". I didn't understand either, until I noticed the text module. So apparently, the text that is typed into a text module becomes the "module name" from the viewpoint of the software.

A little problem with the DX model, the offset on the velocity is killing some of the patches that have finely set levels, like the WURLIZER etc. They were fine tuned to have just enough bite on max velocity so adding a constant 13.5 pushes them into overmodulation.

Ideally, Clavia would give as a choice of velocity curves.

A short term alternative is to use a constant morped to velocity, where the morph range is say 13.5 - 64.0. This keeps the max at 127 but compresses the velocity dynamics.

Users can experiment with the morph setting then save what suits in the DX7.PCH2 file. If you have an engine and /or use an external keyboard you probably can just set it to 0 - 64.

Some of the DX7.PCH2 can be customised (like effect settings etc) and saved to all variations. Deleting some parts might cause problems with the converter however.

I added this constant because some sounds had to less byte on normal keyplaying with the G2 comparedd to playing the same sound on the DX7..
but maybe i overdid it..

Can you do yout suggested tweak and send it in? than i can compare again with my problem patch and we get maybe an optimal balance and can include that as default in the next release?

Re: author's name bug. I am sorry to say that I was mistaken or can't reproduce the error anymore. The part with the error message is true, and the name gets all weird, but just after hitting OK the patch plays fine. I'm sorry for causing confusion, this bug now appears to be purely cosmetic Embarassed
This is what it looks like:

but where is the difference to an offset? do you think the operators are handling vel values above 127 ?
actually they shouldnt

You are right, they do stop after 127.
The only difference then, is that the offset discards 10% of the upper range, where the morph compresses all values into a narrower band in range.

Subject description: Update on the GUI for G2ools
Reply with quote  Mark this post and the followings unread

I was testing nm2g2, and typed a patch name which doesn't exist.
The program did not display anything.

It would be very useful to simply print "File does not exist"

From the GUI's perspective, the gui basically takes the output from the program, and displays it in a text box. When the user enters a patchname which doesn't exist, currently nothing can be displayed in the GUI because there is no output from the program. This leaves the user confused. What happened? Is this a bug?

I could print a message in the GUI which shows "There was no output from nm2g2", but I believe the target application is responsible for producing meaningful output, and the GUI just displays that information along to the user.


Comments please?
