If you want to play with someone using zoom, there always will be a latency. So, i think there is no way to do it in real time now. But if you want to play with playback and translate it in zoom, it will work well. I used Bias Amp before Kemper and i switched on the low latency mod for plugins in Logic in audio preferences. With Kemper all works well, so i use it for my on line lessons.
Thank you for this! Yep, totally aware of the lag between 2 people. Something also you may not know which I found, is zoom will always take the DI signal and there's actually no way to stop that (at least that's what I found). So if you're using a plugin in Logic, the listener on the other end will always hear the plugin along with the DI. It may be subtle, because the plugin will be masking the DI but it's in there too. This was not using loopback btw. It was just straight from Logic using my apollo twin.
Did you find that as well?
Every time I used Loopback with Logic I got latency (but don't remember if I had low latency mode on).
Now, with the Kemper, because all the interface sees is the "Amp" sound direct from the Kemper there should be no "DI" sound involved for what the interface sees. Will experiment with Loopback for sure!
