Hi guys,
just copying a section of my instrument tests over at the 'VST-RTAS Mac bug list' over at the FXpansion forum.

Just to background - I've previously used these instruments (apart from CM-303) in OS9 Protools V5 via freeware VST wrappers such as Ugly VSTi Interface and MultiVSTshell. In these setups the OS9 versions of your instruments worked well.

And to emphasise - I know these are probably wrapper/RTAS problems, but I thought seeing some off these bugs might make you twig as to some of the problems. These are great instruments and it would be great to get them going on OSX !

DS-404 sampler –
* Bits of the interface scatter all over screen when you load instruments - a knob here, a fader there. Sort of a Dali/Picasso VST :-o
* Clicking the main interface mostly brings them back again.
* Some patches can not be read (opaque), but the rest sound fine - it's a GUI bug mainly.
Edit 23.12.03 - tried a new copy of DS-404 from the jan issue of CM, still same problem

CM-303 -
Presets all sound the same (is this usual?) and faders/knobs don't move when you change presets.

SR-202 drum machine (CM / Muon) :

Only loads WAVs, won't load AIFFs.
OS9 versions of this i used (using freeware wrappers like MultiVSTshell and UglyVSTi) always loaded both WAVs and AIFFs. Is the OSX version meant to load both (anyone?)
Edit 23.12.03 - tried a new copy of SR-202 from the jan issue of CM, still same problem

CM-101 synth :

No presets. “Load all” sees the CM101.fxb bank, and “load one” sees individual user patches, but they don’t load (sound doesn't change) and preset always says “empty”. If you create your own preset you can indvidually save it via the Protools saving system.

that's all !
Ta,

There's a couple of things in there that don't sound like wrapper problems.
DS404 - Some patches can not be read
There are some patches (made with the very first version of DS404) that contain velocity values >127 in some of the keyzones. This can cause loading problems in the OSX version with no error message being displayed (though the OS9 version will display an error and the windows version will just correct the problem and continue).
CM303 - Presets all sound the same (is this usual?) and faders/knobs don't move when you change presets.
What presets? CM303 doesn't have any presets.
SR202- Only loads WAVs, won't load AIFFs.
Working fine during testing over here. It's the same code as the OS9 version in this respect so I think the problem is more likely to be the particular AIFF file you are trying to load. Send it to SR202@muon-software.com and I'll tell you what's wrong with it.
CM-101 - No presets.
Again, CM101 doesn't have any presets except for those supplied in CM101.fxb. I don't believe that we ever mentioned in either the CM101 or CM303 manual that there should be any presets but I'll check to make sure there hasn't been a hiccup in that respect.
Edit 23.12.03 - tried a new copy of DS-404 from the jan issue of CM, still same problem
When updates are made available, they are announced on this forum, on our website and on CM's website. We also send details by email to all registered users.

We haven't done any updates since the OSX versions were released so I'm not entirely sure why the January CD versions would be any different :?

Thanks for your reply Dave.

I've checked things further based on your comments, cleared up some things
DS404 - Some patches can not be read
This one was my mistake - some patches were named, for example "AnaStrings.404_", and when I took the "_" off the end, they worked fine. In the OS9 version, this doesn't matter, in the OSX one it does. I'm new to OSX.
CM303 - Presets all sound the same and faders/knobs don't move when you change presets.
What presets? CM303 doesn't have any presets.
OK that makes sense ....... It's just that when you click the standard preset arrows at the base of the wrapped VST, which looks like this :

.... it reads, "Bassline 1"; "Bassline 2" etc, which made me think that they were meant to be presets.
SR202- Only loads WAVs, won't load AIFFs.
Working fine during testing over here. It's the same code as the OS9 version in this respect so I think the problem is more likely to be the particular AIFF file you are trying to load. Send it to SR202@muon-software.com and I'll tell you what's wrong with it.
edit OK, I've just discovered that you have to add the extension '.aif' (not '.aiff') to the files, then they will work.
CM-101 - No presets.
Again, CM101 doesn't have any presets except for those supplied in CM101.fxb.
Is that fxb meant to autoload ? it doesn't. Also tried to load it via the wrapped VST "load all" button (below) :

The other "presets" I was referring to were a bunch of user presets that were either on one of the CM discs at some stage , or perhaps from Patcharena? (AlienLab.fxp, BigKick.fxp etc, 38 of them). Tried them via the "load one" button. Not greatly concerned about these because, as I mentioned, you can make and save your own presets using Protools' own saving system.
Edit 23.12.03 - tried a new copy of DS-404 from the jan issue of CM, still same problem

CM has occasionally had bad files on particular months (from memory, I think with some of the Linplug CM-505 copies or kits), so I just decided to get the OSX versions of everything again in case that had caused any of the problems I had.

I'll update my bug post re the above.

Thanks Dave !

The loading and handling of FXB and FXP files is handled entirely by the wrapper - SR202 and DS404 provide their own mechanisms because they save their own files in a specific way. I would refer these issues back to Fxpansion...

Thanks for your help Dave, have edited my test reports at Fxpansion.

just a bit more on the graphic bugs with the wrapped VSTs of these instruments :

Small graphic bug occuring with the wrapped VST of the CM / Muon SR-202 drum machine :

Clicking load "L" buttons below individual sample pads produces images of the buttons elsewhere on the screen, e.g.

Image

Like the similar DS-404 graphic bug ( VST interface artifacts appear when you load a patch), you can "wipe away' the artifacts with the VST itself.

Utterly bizarre, I agree. However, the window used by a plugin is supplied by the host - which in this case is the adapter - which we then draw in using standard VSTGUI controls. If there was a problem with VSTGUI on OSX in general, it would have been spotted by now I think :-)

Has anyone seen anything similar running in a proper VST host? our testing here (and externally with beta testers) hasn't turned up any problems.

Sounds like a slow screen redraw-could it be his graphics card?

Post

I wouldn't rule it out, to be honest. However we've got an ancient Mac G4 400 with a nasty ATI Rage 128 graphics card that seems to handle OSX in general pretty well without the benefit of Quartz Extreme.

This looks to be an adapter bug. Dave, suggest you close this topic and mail me with links for the latest OS X versions of the plugs.

Sure, no problem.
