so vsts as I know them actually only have 1 program and that is all, each one I think is hardcoded at init time to have a certain number of presets available. Some use different patching algorithms other than steinbergs fxb or whatever it is. An example would be like oxeFM synth or quadraSID, which both have 0 programs available via program changes, but, both have alternative menus to browse through presets.. (why I don't know)...

Not sure if it's relevant here, but I've found that within vst~, some plugs respond to a 'normal' (midi formated, ie. 192 i ) program change message, whilst others, notably Pluggo's, require a simple int. cheers Roger

VST plug-ins in general do not "have" (midi-)progams, and therefore do not recieve program change via midi. there might be exceptions.

if it works in certain apps, this is controlled by the host.

you can do this translation from program number to vst preset number in maxmsp easily by yourself, isn t it?

i would recommend to use *bank select* for *vst presets* rather than *program select*

eh, you were not asking for midi but for switching presets so disregard the above.

Thanks for all the replies. It turns out that preset changes aren't supported for these plugs, which is a cryin' shame, as they sound really great. I tried to cheat by sending a 'param' message, recording the values, and feeding them back in. That doesn't work either, as sending a message such as "3 0.5" apparently just sets that parameter to 0 (with these plugs). Oh darn. I haven't been that excited about the sounds I was getting from an off the shelf product like this in some time, but I need to be able to automate the rapid switching of presets....

thanks again, Michael

could you tell me which are the ones which do not work for you?

i just tried the ones which are available for OS 9 on OS 9.

switsching works, but it is very slow! up to 10 seconds! it is much better when the GUI of the plug-in is in foreground, but that ddoesn t help us with this weird problem.

anno, now i have it :P

the preset change is only executed on mouse-over over the plug-in GUI (of psp-42/84 in that case)

so it is the plug-in s fault ... though it does not happen in nuendo, cubase, and logic (4.8 classic)

-110

the real bummer is that the psp "608" plugin will actually report param values, and allow you to send messages to set param value. in lieu of being able to change presets, this is a good kludge. however, as mentioned before, for some reason (incomplete implementation of the vst spec!, ahem) this doesn't work on the 42/84 plugs. hello people, just throw in the same param reading code and fix it, or better yet, support preset changes like a well behaved citizen!

-m

today i tried 42/84 it again - and it works ... with both, edit window open and closed.

not all of the reported parameters are stored to preset in the PSP plug ... that is nothing unusual but might cause you trouble in MAX.

the "repeat infinite" VST parameter for example does not go into edit presets ... and is even set back to "0." (turned off) after sending the bypass message to [vst~] (or the equivalent VST message in a steinberg host)

maybe that is what is confusing you, besides all those wrong assumptions i made in my last posts.

Hi Roman, I tried to email you about this offlist via the forum's email option, but there was an error that said it couldn't determine your email address.

In any case when you said re: the 42/84 vsts that you were able to get them to work, what exactly were you referring to? I.e., were you able to get them to change presets from Max? Or were you able to send parameter values from Max and have the plugs respond? I'm currently not able to do either under OS X 10.3.9, and working with the demos. Do you have an example patch that you could send me? thanks!, Michael

very strange- when i send a message of 2 i get the error message "program 2 outside effect's range"...

oops. what about other hosts. maybe the new demo versions do not have programs ? :)
