Jamulus client macos (Mojave) & Roland TD11
- Roland TD-11 < USB > Mac Mini (Mojave)
Jamulus sample rate
In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave (a continuous signal) to a sequence of samples (a discrete-time signal).
Internally, Jamulus works on a frame size of 128 samples (64 with version 3.5). If you convert this size to 44.1 kHz, you do not get an integer number but 139.319…, which requires additional effort for resampling and processing time, which in the end adds to the latency issue.
Unfortunately the Roland TD-11 supports 44.100 Hz only.

Connecting the TD-11 through an audio interface which supports 48.800 Hz requires rerouting audio – VST plugins are not supported with the Jamulus client. Get a copy of an audio rerouting tool (e.g. Loopback, Blackhole and configure accordingly:
Latency sucks! I tested Jamulus during the Covid-19 crisis, as many did. Having the proper gear to do online jamming is a main prerequisite. If so, things become “realistic”.
