Hi, Yes this is all very good information. I haven't used the Web IDE before, so that was nice to see.
Using the .dsp code from the ex. tutorial https://faust.grame.fr/doc/tutorials/#adding-an-envelope-generator , in the Web IDE it sees my midi keyboard, and shows the midi note number. import("stdfaust.lib"); declare options "[midi:on]"; declare options "nvoices:12]"; decimalpart(x) = x-int(x); phase(f) = f/ma.SR : (+ : decimalpart) ~ _ ; timbre(f) = phase(f)*0.5 + phase(f*2)*0.25 + phase(f*3)*0.125; process = timbre(hslider("freq", 440, 20, 10000, 1)) * hslider("gain", 0.5, 0, 1, 0.01) * (button("gate") : en.adsr(0.1,0.1,0.98,0.1)); effect = dm.zita_light; However the result is the same as always when I hit run. I get a gui with the ubiquitous gate button. What I'm searching for is to play a key on the external usb midi keyboard and have it play the corresponding frequency. I can make a single midi key control the gate button, but that's still not quite I'm searching for because I still need to change frequency using a slider. There must be a way to set frequency to the midi keys in the .dsp, but this bit of code model seems hard to locate. It might look roughly something like this, but not sure how to pass note numbers # to the midi key. freq = midikey2hz([midi:key #]); ... process = gate* freq; Regards, Bob On Wed, Sep 23, 2020 at 4:06 PM Thadeus Reed <t...@creativecontrol.cc> wrote: > Hi Bob, > > I'm not sure what your development setup is but I found it very helpful to > use the Web IDE when developing https://faust.grame.fr/ide/ .
