IX Snapshot 1.0 (initial release and subsequent flurry of fixes)
+ Fixed error when learning MIDI for the Clear button
+ Handle machine name changes
+ Handle machine track changes
+ Fixed stupid confirm on capture bug.
+ Fixed errors fetching machine data size (thanks wde!)
+ Machine data sizes update when user clicks Snapshot GUI.
+ Machine data info shows both stored and current size.
+ Added buttons to manage selection.
+ Added option "Selection follows slot".
+ Added option "Confirm on clear/purge".
+ Added tooltips to most controls.
+ Fixed error on load due to deleted machine state container being saved to song even though no properties were saved.
+ Minor improvements to MIDI mapping dialog.
+ Support delete/undelete of machines
+ Prevent crash when attempting to restore state for a deleted machine
+ Initial release

Right-clicking a button will open a dialog so you can assign a MIDI event to the button you clicked. If you hold CTRL and right-click, you can map MIDI to the current slot, so you can assign MIDI events to specific slots. The mapping dialog shows which property you're assigning in its title bar.

I don't think anything will change as far as the core features are concerned. I'll add extra stuff to the UI to manage the slots and data but any future releases should be fully compatible.

I think it's stable but for some reason, whenever I'm running a debug session in Visual Studio, Buzz crashes unexpectedly for no apparent reason. I'm 99% sure that this is because of Visual Studio rather than my machine since it doesn't seem to happen when I run Buzz normally, but save often and report any weird behaviour.

Feature requests and bug reports welcome. Enjoy!

p.s. MASSIVE THANKS TO WDE AND UNZ FOR AWESOME HELPFULNESS!!

Wow, fantastic work! Very usable tool in many different ways. I just love the fact that I can save a number of options for a machine and go back and forth to explore different combinations. And misbehaving VSTs are not that big of a problem anymore!

Going to be another essential machine going forward.

I'll test more when I have time but I noticed couple of bugs:

If you click machine name all goes well but expanding the tree view causes quite often infinite loop of dispatcher errors. Happened so far only with VSTs.

It also seems that 1. adding machine A, 2. capturing machine A to 'slot 0', 3. deleting machine A and finally restoring 'slot 0' causes a crash. Maybe cleaning up the capture when machine is deleted should fix it.

Not sure I understand but I'll poke it and see what happens.

Ah yes, forgot to check for that. I'll get on it!

i have observed the same thing happening in buzz for a few years now (not related to this machine).
my hunch is that some VST try to detect if you run a debug session and something goes horribly wrong there... (i know because one of them flat out displayed a message saying it's going to crash now because it doesn't want to be reverse-engineered..). Or just the fact that memory is initialized to different values when running debug mode, or an entirely different allocator might actually be used and align/pad things different which happens to trigger some bug in other machines which access that invalid memory....
the other suspicion i have is that the .net gui part is somehow to blame, because i get a ton of error messages in the output window while running in debug, and i don't even have a custom theme going or anything, as barebones as it gets, but something is throwing a lot of wpf/.net expections constantly..

Yeah, I have similar suspicions. The reverse engineering thing has annoyed me sooooooooo many times. I haven't got a clue how to reverse engineer a VST, I can barely forward engineer my own code!

Update: Fixed the missing machine crash.

• State information for missing machines is now ignored but not removed (in case the machine gets undeleted).

• Data for missing machines will not be saved to the song file.

• Purge will now get rid of such data (as well as data for non-selected properties as before)

I should probably add a way to select any active stored properties so you don't accidentally purge things you want to keep...

I'm not seeing this. Expanding/collapsing etc. works fine with no errors here. I haven't tested many VSTs but I wouldn't have thought it would matter which one it was, as they're all the same PVST machine as far as Snapshot is concerned.

Yeah it seems strange. I still get the error but managed to limit the problem. So I'm running 32bit Buzz and testing Snapshot with FB-3300.

I get the issue with 64bit version of the vst, 32bit seems to work fine. Maybe this is related?

Thanks for the update!

[IXix]

Updated. Added a bunch of mildly useful UI stuff and fixed a stupid bug that hopefully hasn't affected anyone yet.

Tried that vst in all platform configurations (32/32, 32/64, 64/32, 64/64) and still didn't see anything strange. I don't think the msdn link you posted is relevant in this case but I could easily be wrong as all this WPF stuff is basically voodoo as far as I can tell. If you feel like investigating, you can peruse my shoddy and amateurish code at https://github.com/IXix/IX-Snapshot.

A super "PeerState", just try it today with Qsamo, and yes its a real snapshot , wonderful, works in Buzz64.
Its time for me to buzz again, after more one year of interrupt.
Great work.

Glad you like it! Check the forum regularly as there's a couple of bugs being dealt with as we speak. I'll probably put up a new build later tonight or tomorrow.

It's not supposed to ask for confirmation when you capture and it can throw an error if you answer no. Also, wde has found a problem related to retrieving the size of machine data. I can't reproduce that one so it's possibly system or options related.

Hey, great that you did it!

I am very sad that I can not test in the moment, because of a serious situation in my new home (moved). Hope I can try it soon...

I hope your situation improves soon.

Updated again. Fixed a few bugs.

[IXix]

Oh, it's not aware of machine name changes or more importantly track count changes. Sigh. On it.

[IXix]

Ouch, sorting out the tracks problem really bent my head.

+ Handle machine name changes
+ Handle machine track changes

Like deleted machines, stored values for deleted tracks are kept around in case the track comes back. Purge will get rid of them.

Awesome, man
Are you planning to add some kind of snapshot manager from PeerState? With manual snapshot morphing, interia and a little randomisation (all controlled by MIDI of course ).

Edit:
hot report: CTRL + right_click on 'Clear' gives error

Yes but probably not soon.

hot report: CTRL + right_click on 'Clear' gives error

Thanks, I'll fix that as soon as I can.

[etruscan]

Thanks IXix! As much as I love PeerState, it does crash on me regularly, and your machine is very welcome and timely

The only thing keeping me with PeerState is the inertia parameter for morphing between states. This produces interesting results, and is also a nice way to do parameter slides (e.g. filter cutoffs). Do you plan to add inertia to Snapshot at any point?

Probably. I pretty much want it to be a complete PeerState replacement. Not sure when I'll get around to doing it though.

Little bugfix...

Sorry it took so long! I have to admit I just forgot.

[etruscan]

I loooove the way this handles VST snapshots. No dicking around assigning parameters to Polac VST tracks; it just works! How cool is that? *

* IT'S VERY COOL
