Strange. I thought that 'note' articulations have no effect, and I fixed that. As I see 'phrase' articulations should work. I suspect that the note off comes too soon after the keyswitch event. I'll check this and will send you an update.
Thanks,
Attila

Hi Attila,
Thank you for the RC 3.41 update! A follow-up on my previous bug report:
Thank you for the RC 3.41 update! A follow-up on my previous bug report:
- MIDI In not working in Chord Selector but in Quick Suggestions: Works well now.
- Crash while selecting a chord: No more crash -- huge robustness improvement for me!

- Noise when using MIDI In in VST mode: Still happening. Since changing a chord using a mouse click does not cause click/pop noise, this may be still an issue specific to handling MIDI In. Increasing the audio buffer size (2048 samples) does not avoid the noise completely.
- Undo for Quick Suggestions: Mostly fixed (please see below for the unfixed part).
- Undo for Phrase Envelope Editing: Unsupported. I guess this was not part of the update.
- The small MIDI In window accessible via Quick Suggestions shows "Click here to set a valid 'MIDI Input' device!". Clicking this link in VST mode causes a crash because that the MIDI configuration is unavailable in VST mode.
- The small MIDI In window via Quick Suggestions does not support undoes.
- Not new in RC 3.41, but I see visual glitches in various parts of the RC interface, including the main window and Chord Selector. When some part of RC is redrawn, random label/button text occasionally disappears or shows black/white box instead of the actual text, even when the text itself did not change. Some other repaint event fixes the text automatically. This is mostly benign as it does not seem to cause crashes at least on my system, but it does not appear to be an intended behavior.
- Pressing Ctrl-A in Note Editing only selects all phrases but none of the notes. To select all notes, one of the notes in the selected phrases has to be clicked after Ctrl-A. Not sure if this is intended because selecting all notes seems more straightforward while Note Editing mode is active.

Hi particle_filter,
thanks for the detailed feedback, it is very helpful for me.
I did not see such rendering artifact on macOS.
I'll update you on the progress.
Thanks,
Attila

I am investigating this right now.particle_filter wrote:Noise when using MIDI In in VST mode: Still happening.
No, sorry this will be fixed later.particle_filter wrote:Undo for Phrase Envelope Editing: Unsupported. I guess this was not part of the update.
Right! I fixed this embarrassing bug today.particle_filter wrote:The small MIDI In window accessible via Quick Suggestions shows "Click here to set a valid 'MIDI Input' device!". Clicking this link in VST mode causes a crash because that the MIDI configuration is unavailable in VST mode.
This is a known problem, and a very annoying one. It looks like another race condition, but I have checked text rendering hundred times before, and I confirm text rendering is protected by a mutex. At the moment the host OS font rendering services are used, but I am considering to return to freetype which was used in RapidComposer 7 years ago when it was first released. However freetype font rendering was bad quality 6-7 years ago, so I started to use font rendering built into Windows/macOS.particle_filter wrote:When some part of RC is redrawn, random label/button text occasionally disappears or shows black/white box instead of the actual text, even when the text itself did not change.

There is indeed something wrong with Ctrl-A! I am investigating this too.particle_filter wrote:Pressing Ctrl-A in Note Editing only selects all phrases but none of the notes.

This bug has actually been around a while.. (just getting around to pointing it out..) The dialogs can become "see through" under certain conditions. In this example, it happens to the chord suggestions, but, other dialogs can do this as well.
I am in the process of testing all my favorite VSTs, so, I also showcase a little of what I am working on in the end of the video..

Oh, no, this is rather serious. I made substantial changes about mouse click handling. Although I tested it a lot, a few issues avoided my attention. I am preparing a new update.BluGenes wrote:This bug has actually been around a while.. (just getting around to pointing it out..) The dialogs can become "see through" under certain conditions.

I liked the song in the end! Very nice!BluGenes wrote:I am in the process of testing all my favorite VSTs, so, I also showcase a little of what I am working on in the end of the video..

Good news...
The crash and weird mouse clicking issues reported by lulukom and BluGenes are fixed now.
Click sounds when releasing keys in 'Chord Selector' and 'MIDI Keyboard' fixed in the VST plug-in.
Undo works during phrase envelope editing, and it is saved properly.
Issues fixed with pressing Ctrl-A immediately after switching to Note Editing mode.
v3.42 will be available tomorrow. Almost all reported problems are fixed.
Thanks,
Attila
