Working in reaper, I noticed that I am missing the first note often of a drum beat when reaper is cycle\loop enabled, with short 1 or 2 bar loop.
I tested in Bitwig and Ableton as well, and get the same missing note in Bitwig, but not in Ableton. I tried pretty much every buffer\pref tweak in the DAW's and plugin that I could find with no change\success.
I am on Mavericks, tested as VST and AU (and enabled AU timing pref) on 64bit reaper.
If you need more info to repro, please let me know,
Geist v18.104.22.168 64bit REAPER 5.94 x64 Windows 10 64bit
This is still an issue. It also depends where on the timeline you start playback. I find if I start playback from the very beginning, there are never any missed hits. Starting playback anywhere else (at a position where Geist2 should start at beat 1) sometimes misses the initial beat (depending on where playback starts; and tempo, as explained by gwok). Confirmed no missing beats in song mode.
