if you want to sound like a specific piece of hardware, do some research on it and you should be able to figure out what kind of sounds it could make. -- Brad Smith On Tue, Dec 21, 2010 at 1:40 AM, Alan Wolfe wrote: > Hey Guys, > > I'm making a programmable synth type PC prog

Some years ago I wrote a stand-alone windows program to do it: http://www.rainwarrior.thenoos.net/intun/index.html It still works. Unfortunately, I lost the source code to it, so I can't make changes anymore. (I should have made it open source.) -- Brad Smith On Fri, Jan 14, 2011 at 1:

work for sound as well) is to downsample, apply convolution, then upsample. Of course, you're going to lose the higher frequencies in the downsampling step, but it can be useful in situations where that is an acceptable trade. -- Brad Smith On Tue, Jan 18, 2011 at 2:46 AM, Uli Brueggemann wr

rence between them (probably it just turns into white noise once the feedback gets going). I think this precludes being able to buffer individual operator outputs, though; you need to calculate the whole chain on each sample to produce the feedback value needed for the next sample. -- Brad

Also, if supporting multiple samplerates, to keep the sound consistent your feedback multiplier should scale according the samplerate. I believe a linear relationship will keep it sounding similar. -- Brad Smith On Mon, Sep 12, 2011 at 1:55 PM, Tom Wiltshire wrote: > Now I get why the bl
