when put together become a Frequency Modulation sound module.
(Its FM synthesis is not at all based on any Yamaha FM chip.)
2012 June, 3 new demo tracks
- Those 3 tracks have been mixed using only EQ, compressor and pan, drums are not PreenFM -
VST mdidi plugin for Win32/64 and Osx
to control all PreenFM parameter from you Daw
"I’m no synth lightweight, I have over x20 hardware synths, mostly analogue....
The Preen is a really good FM synth. I have an original DX7 & prefer the Preen.....
I went into it for a build for fun & ended up with a professional sounding synth.."
"Received the kit and I must say you did a FANTASTIC job laying out the parts, providing clear instructions, and choosing high quality materials for the build. This is a quality job fromtop to bottom! Thank you! I built it last night in two hours."
Presets-based demo - 1.0x firmware
"Just received and built mine, Totally awesome, love the open architecture of the synth, multiple algorithm programs is really nice.
Has a great signal to noise ratio and a very user friendly interface!
Small enough to carry around, so it's going to be an intense FM sound design weekend!"
New firmware - Step sequencer demo
"I am a big fan of vintage FM synths. I have quite a collection of them, and have worked with most of them with sound programming.
I have a DX 100, TQ5 and a Sharp X68000, and most of the 4 ops and OPL synths sound pretty much the same.
This one is totally different, has a different sound, and it's really good. It can sound super harsh, and ridiculous, but also really soft and sweet. I'm actually thinking about learning how to code to work on this guy.
I really like that it is also polyphonic, so far the only diy synth that does polyphony!"
PrenFM is open source and open hardware
That means that you can take the source code, modify it, compile it, and upload it into the flash memory of your PreenFM.
That means that if you want a custom case, take the map schema, change it and order one on Ponoko.
I learnt many things looking at other open DIY project, i hope some people will learn somethings doing or just looking at this one.
If you improve anything, don't forget to share.

"I received the synth today in the mail, and just finished it about an hour ago and gotta say, it rocks.
Good Job man. I have built quite a few of these DIY synth boxes and this one is definitely one of the best.
Good documentation and overall a great sounding synth."
Aerodynamic Shape :-)
"All went well and really fast. the resistor sheet saved some time, too.
great project for beginners i think."
