I'm having a weird problem while trying out the demo version of Studio One 2. Here's the workflow:

* Open a new, empty song
* Drag SampleTank onto a new track
* Record multiple events on a single track (using the same preset or a different one)
* Save and close the song

When I reopen the song, all of the MIDI data in the events has been replaced by the data in the last event recorded.

For example, if my first event is a 10-bar piano line, a second is a 6-bar line, and a third is a 4-bar line, the four bar line will replace all the MIDI data in the first event (leaving bars 5-10 blank) and the data in the second event (leaving bars 5-6 blank). (See screenshot.)

This has never happened with other VSTs, only SampleTank.

If I have only one event per track, everything is fine.

Any ideas??

This is a Windows 7 64-bit machine running the 32-bit S1 v2.6 demo and SampleTank Free 2.5.5.b.

Try renaming the tracks without the dot in the name before saving. Studio One has a bug at the moment that doesn't like a dot in the track name and causes corrupt midi data.

@JDENT - Brilliant! Thanks! The short story is, that solved the problem, and is easily reproducible. I even got it to break Presence instead of SampleTank to take the third-party aspect out of the equation (see screenshot).

To reproduce this example:

* Open a new song
* Drag SampleTank (or any instrument) into a track
* Rename the track to omit the dot ('.'): SampleTank2.x ==> SampleTank
* Record more than two separate events
* Save and close the song
* Reopen the song; everything's fine.

In this example, I then also:
* Dragged an instance of Presence into a second track
* Renamed the track to include a dot
* Copied the events from Track 1 to Track 2
* Saved and closed the song.

When I reopened the song, Track 2 was corrupted.

Man, it's those little things that drive you nuts!

One obvious workaround that I just tested was creating a new track prior to dragging a VST into it.

I was dragging SampleTank into a new trackless song, so the track name assumed the name of the VST by default. Creating a new empty track first will give it a numbered track name that won't change when you later drag in an instrument (Track 3 would be the default name in my prior screenshot).
