ChordCV rack crash

[ContemporaryInsanity]

Hi,

I have a LFO modulating the voicing input, if I then change type using the knob it crashes rack.

Stack trace follows:

same issue here, even when I turn the first 2 knobs ( debian ). Adding here the logs of jackq :

Similar crashes here, using SEQ-3 module to drive the chord progression and Conv module to convert to +/- voltages for Root and Type.

I've saved my patch with the sequencer paused. This is stable until I start SEQ-3 (by clicking Run), then Rack will crash after just a few chords (steps) have played. While the Rack UI is frozen, the sound will usually keep playing. Here's the end of my Rack log file:

EDIT: By the way, this module is great!

[worktycho]

It looks like this can happen if the selected inversion is a sharp when drawing. The cause seems to be not providing space for the trailing null in the name buffer. I've submitted an MR with a fix.

[Eurikon]

Hi, i like your Chord module a lot and use it often, but it crashes all the time as report above, also for me. Will this be fixed anytime soon?

[Petervos2018]

Does this solve your problem ? :

https://community.vcvrack.com/t/chordcv-linux-fixed/13373

[KingKone]

Yes it's the fix from the PR from worktycho. I compiled it. So happy I am Daniel. The VCV topic was made by me

[Petervos2018]

Not a Linux guy myself, but was hoping that posting in this issue would attract some attention to the guys who posted here with problems, and show them a link to a fix.

[KingKone]

the fix is here: https://github.com/aaronstatic/AaronStatic_modules/pull/6 but aaronstatic has not merged it since summer last year

[Eurikon]

How can we get this fix working for Mac and Windows?

[KingKone]

i try to find someone who can do a windows and osx version and will post them here

tryed to get VCV running on a windows VM and some dll files are missing, and i will not enter dll hell again, left windows years ago because of that shit =D

[jimallman]

Here's your fix compiled for MacOS. It works! (At least my Pachelbel's Canon test patch now repeats with no problems.) Great to be working with ChordCV again!
