I play keys and run the click for our band, provided by the Cantabile metronome. I’ve noticed during our performances that sometimes the metronome sounds will stutter. The tempo does not change, it just sounds like the actual metronome click sound is delayed. It’s not consistent; the click will play delayed for a fraction of a beat and then be back on tempo for a few minutes, then glitch again just for a beat. It’s almost subliminal, I find myself thinking, “did I just hear that?” However other band members have noticed it as well. Again, the actual tempo doesn’t change, the clock keeps running correctly. It just feels like the audio playback of the metronome click stutters. I’m using the Cantabile “Modern” click sounds.
My other keyboard sounds are completely unaffected. I play a mix of Kontakt, Omnisphere, UVI, etc. piano and pads. I have run the Cantabile profiler during a session and do not see evidence of overtaxed cpu.
I have been unable to duplicate this at home in my studio, only during performances. The only difference between home and stage is audio i/o - at home I use a Behringer UMC and on stage I use the Dante Virtual Soundcard going into a Yamaha console over ethernet. (VST audio submixes go out to Dante channels 1-8, metronome click is on channel 9.) Laptop is the same - Lenovo laptop with Windows 10. I use different Cantabile profiles depending on where I am to map keys and channels (thanks Torsten for excellent advice on abstraction layers).
Anyone else run into this, or have ideas for troubleshooting?
