Trying to create an oscillator that I can use different fgen waveforms selected using something like a combobox widget any ideas on how to do this welcome the whole project is to build a vst instrument also handy to be able to use a rslider widget to alter the phase of the waveform 
Oscillators as sources for vst synth

This is the code I have so far and I'm wondering where my syntax is going wrong I'm try to create a wave table synth that I can choose either a sine saw square or pulse wave using a combobox widgetform caption(“Synth”) size(400, 300), colour(58, 110, 182), pluginid(“def1”)
keyboard bounds(8, 158, 381, 95)

Changed up the syntax I believe it’s more accurate but I’m still not having any luck
Was hoping someone might have any ideas
where I’m going wrong
Wanted to know the name of any good csound
Learning resources
You can just use an i-rate channel to get the waveshape you want.
iwave chnget “combobox”
aOut oscili p5, p4, iwave
Channels can handle i, k and a rate data. The floss manual is a good resource for learning Csound. I think this book is one of the best out there.
That’s brilliant but what if I want to use multiple oscillators and a combobox for each oscillator
Just modify the code above? I think it might be worth your while going over the Csound floss manual first. It’s quite hard to jump straight into Csound. But much of what you are trying to do should become clearer if you start at the beginning and work from there.
