    Project Feasibility, help with ideas etc

    Hello,

    I am looking to make a large scale audio installation where people would walk through and trip lasers or some other sensor to trigger "strings" or some other sound effect. I have built a project using the teensy before that was a modified touch guitar which was pretty straight forward. The catch here is that I would like it if I could have each string have its own output without having to have a teensy per but there are only 2 DAC's on the teensy. In total I was hoping for 9-18 "strings". I really liked the results of the karplus stong strings in the library, but the other audio synth stuff is great as well, but I am just not sure what my options are for have so many outputs.

    Any thoughts on how you might accomplish this sort of thing?

    Thanks in advance

    Jon

    You can use TDM to get many channels of input and output. Here is Paul's original blog post about it: https://hackaday.io/project/2984-tee...annel-audio-io
