vst program changes w. PSP vsts
I’m testing out some demos of the PSP effects VSTs (PSP 608 Multi Delay, etc), and having trouble sending program changes (but not parameter changes). Sending ints to the inlet of the vst~ object just gets a report that "program [insert random int here] outside effect’s range". Is anyone able to get these plugs to see program changes under OS X?
Since I haven’t used that many vsts, but had this problem with another plug, I’m wondering: anecdotally speaking, are there many widely available plugs that don’t see program changes within msp, or is it just my bad luck?
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.
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
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)
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!
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
maybe that is what is confusing you, besides all those
wrong assumptions i made in my last posts.
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?

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

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