Sound Test Successful
I installed Cubase on an old Dell laptop and managed to get the vocoder sounding fine despite a pretty nasty 0.3s latency. That is, when I talk there’s a 0.3s delay before sound comes out of the speaker. It shouldn’t matter as I’m not expecting to be making conversation in it and so long as it sounds ok, that’s all that matters.
The laptop has about a 4hr life on batteries so that’s plenty for any performance. It’s also not very heavy and produced very little heat so it should be find to sling on my back.
