If you are using a EWI 4000, you can trigger the EWI's audio output on an oscilloscope on one channel, then attach the other channel to your PC audio output. It should then be very easy to see the latency. Brad On 11/14/2015 12:19 PM, Ben Gonzales wrote: Hi all. How do you measure latency wi

Hi Ben, 2015-11-14 21:19 GMT+01:00 Ben Gonzales : > 1. How does one measure latency for a wind controller? An easier and more accurate way to measure the overall system latency could be to measure it while changing from one note to another: Use a sound card with two channel (i.e. stereo) input.

Hi all. How do you measure latency with a wind controller? I decided to try the "record the actual sound and analyse" approach. I tried using a mic next to the mouthpiece to record my "pfft" (leaking out the side), and the synth-ed sound that followed. It was difficult to distinguish the sou

Hi Marcus. Gee, that looks like fun! I hope you get a great response. You've obviously put a lot of work into the project. I haven't actually measured the latency. All I know is that the sound comes out without enough delay to annoy me! I take it you'd need an oscilloscope or similar to meas

Hi Ben, very interesting project, thanks for sharing! I'm also working on a (commercial) project with Fluidsynth on ARM hardware, but I'm using an Allwinner A20 SOM board. I'm producing it commercially, because I'm also developing the controller hardware (the instrument itself, with all the keys e

Your project inspire me a lot. I am also making a similar project with similar tools but talking with digital piano using a little bit more powerful Intel Compute Stick. > On 2015年10月31日, at 上午5:00, Ben Gonzales wrote: > > Hi all. > > I'm running my EWI-USB through a Raspberry-Pi 2 using Flu

Hi all. I'm running my EWI-USB through a Raspberry-Pi 2 using FluidSynth. It was a challenging project, and it now works well. Here's the web page: http://projects.gonzos.net/ewi-pi/ Interesting features: - I configure the running FluidSynth using a smartphone accessing the R-Pi via wifi (n
