I had the same problem and installing the newer Microsoft runtime worked for me too.
Thanks!
Thanks!

preenfm2 and preenfm3 / Re: PreenF405 VCC Pin 64 / C1 Airwire

I noticed this as well. I added a jumper from pin 64 to 3.3v on the module. Don't assume that the 3.3v and GND pins on a semiconductor device are connected together inside the chip - in some devices they are not and you could be powering a section of the part through some parasitic internal path. Not good.

I found a great tool for making band limited waveforms: https://www.futur3soundz.com/wavetable-synthesis
Near the bottom of that page you will find a link to WCreate and instructions for using it. It creates .wav files with a specified number of samples (use 1024 for Preen) and sinewave partials in the magnitude, frequency and phase you want. I used the method mentioned at the top of this thread with Audacity to convert the .wav files .txt files for Preen.
I'm finding the additive synthesis possibilities with Preen algorithm 27 quite interesting. For example you can use WCreate to make a waveform with some harmonics and another one with some of the same harmonics 180 degrees out of phase. By adding the two in the right proportions you can remove harmonics from the first waveform. This can be controlled by the operator envelopes to change over time. This allows more precise control of harmonic content than the FM algorithms.
WCreate also makes awesome sounding organ tones!
