I putted Ableton Arp device into Vavra.
When I holding 3 keys on the keyboard it plays arp pattern but when I record this to midi and play, it plays from midi something different, sound is different, chopped.

Ableton 11.3.10 bug or Vavra bug?

 

Since you seem to have problems with both DSP56300 emulations, why don't you test the same thing with other synths. Use something maybe somewhat cpu heavy to try replicating with another plugin. Maybe like Serum. I probably wouldn't go as far as to test with Diva. Try a few different plugins and maybe you can find some things they have in common.

the sound is probably glitching during the 3 key arp playback. You could also use another Chord Trigger/Arp midi FX plugin to play one actual key which will trigger the rest of a full chord. When you are using a plugin that is provided free, like these; you are a beta tester in some sense. Even if they have it mostly ironed out. Experiment.

 

Latest version? 1.2.36?

 

no problems here just testing it out vavra or osiris with the arp. reaper win 10. although there is a bug with osiris i get where occasionally all of the saved presets get wiped and reset to the initial ones which is super super annoying, not sure what causes it. song will load up fine for weeks then all of a sudden lost. i think i read they're currently working on the presets for the next update, that'd be dope.

 

the original post is in reference to Ableton. It has it's own MFX arpeggiator plugin: https://obedia.com/how-to-use-ableton-live-arpeggiator-midi-effect/

So using one in Reaper is not the same thing, especially from a bug hunting perspective; even if the midi output is the same. There are many other Third-party ARP MidiFX plugins like Nora, Cthulhu that could also be used to test this. A lot of synths have their own arp section as well, and they can give different results sometimes.

The problem could be Ableton ARP mfx, but I do not use Ableton to check if that is a bug in his version. (check changelog for it). These are two of my favorite synths to create arps with, and I think they would also be for other people so they have probably been pretty well tested already. Sometimes the problem is just the combination of two versions who do not get along well.

 

Yeah. Latest version VST3 1.2.36

 

Yeah it could be it. I remember in Ableton 8 there was bug with Arp when you looped it first bar triggering different giving different sound than the rest bars in the loop.
