Hello, I have two external synths connected to Renoise via a Firewire audio interface I just bought. When audio from the synths and Renoise are routed through the software mixer that came with the audio interface, there’s no audible latency. But when I try to use a Line-In device in Renoise, and set the Line-in device and select MIDI return mode in the latency dropdown, there’s latency. So, I went to audio preferences in Renoise, and tried to reduce latency to as little as possible, and it seems I can’t reduce latency lower than 1 millisecond.
I don’t know enough about all this yet, but I thought that buying a Firewire audio interface would have allowed me to use my external synths in Renoise, apply DSP effects, and have no latency doing all this in real-time. Was I just being naive in assuming this?
The rule of thumb I’ve heard in the past is that less than 10ms is not audible.
I think it’s probably impossible to have a midi system with less than 1 ms of latency. The round trip that the data takes through the interfaces is just going to take longer than that.
