Cthulhu was updated to v1.15 on April 29. On May 16, v1.15e for OSX was posted (to fix a 64-bit AAX validation error in ProTools).
 
Download from your account.
 
Version 1.15 changes:fix: alt-drag on note-number boxes of current selected chord (to transpose all notes in chord) was not working.added: Menu->Transform->”Fill all Chord slots with current chord”.  Uses the lowest note of chord as ‘root’ location and copies the chord to all chord slots (transposed).
 
And if you're way behind in updates:
 
1.14 changes:
 
fix: if using Note Latch switch + toggling on/off/on using the Arp could trigger “previous” notes
 
fix: for having host cycle enabled but playing a song position outside of the cycle, could cause dense (repeating) MIDI output streams.
 
added: can now batch import MIDI files via drag and drop to Piano keys.  If a single MIDI file is dragged, it functions the same as the menu import.  If multiple type 0 MIDI files are dragged, then it acts like a ‘batch import’ - each file becomes its own chord preset, saved adjacent to the MIDI file (same name, but .fxp extension).
 
added: checkmarks now display in main menu to display subfolder with current item (note, checkmarks don’t persist on re-opening a song/project because the preset is now stored in the song, not from the menu)
 
added: alt-click on disk icons to quick-resave (overwrite) a preset (no dialog windows / warning).
 
Whats new in v1.1:

• Redesigned graphics by Lance Thackeray.
• 200% high-resolution zoom option for the entire UI.
• Option to run the Arp clock free (Hz).
• Menu item for fast access to the Presets folder.
• Menu item to open the manual .pdf.
• Chords module now defaults to triads instead of silence.
• Preference added for default zoom amount (100/200%).
• Preference added for test-tone default (on/off).
v1.11a fixes an issue in Reaper (windows only) title bars overlapping on top of UI
v1.11b fixes "arp rate" label not always visually updating in all hosts

Cheers, TM!

Thanks John!!
 
I rarely go into xfer's site (possibly only when someone in here asks a question which prompts me to make the effort).
It'd be professional, advantageous, good, nice, a friendly courtesy if Steve would just send an email or link when these updates are released........you know, communicating with the customer base to keep the customers informed of updates.  

Heck, I'd be happy with just a post in the Cthulhu subforum.

Thanks TheMartian.
 
Well, since I took your tip and stopped by the Xfer site to pick up the Cthulhu update, I checked on the others and there is also a May 17 update for LFO Tool (which I also grabbed):
 
LFOTool for Windows 1.67
Can click for focus view lock on either Filter frequency plot (click background of filter section on left) or graph / do not draw filter plot (click in background in routing area).  A border will draw around the corresponding section to indicate this is the locked view.added dedicated MIDI cc contorl for cutoff slider (59) and LFO Rate (60).fixed issue with lowest MIDI notes to graph assignments control.

Has anyone experienced a problem whereby opening the GUI obliterates the arp preset you're using? Happened to me twice.....

i have not experienced this

I can't get the the arp to work nor can I get the chord function to work. Just to make sure I was routing/setting it up correctly, I followed Maartian's excellent guide here: http://forum.cakewalk.com/Chord-memorizer-like-on-Logic-Pro-m3417049.aspx
 
When I click on the Arp button, the sound just mutes. The chord function doesn't do anything when selecting a preset.....(unchecking the Arp) I can only hear the synth I chose and/or the included Cthulhu synth.
 
Summin aint right with this update..... 
 

Summin indeed aint, Lord M.

Think I'll wait on downloading these two....
