PreenFM1 (the blue one) / Re: Build a PreenFM from PCB with chinese maple clone

« on: November 21, 2012, 07:44:00 PM »

So here is my PreenFM made from a bare PCB and a maple clone from ebay
Case is made from the scrap material pile at the Fablab Utrecht.


The maple clone is a different size as the original. I first put the headers in the 40dip and then put the maple on and soldered it. The clones is also reversed from the original, the buttons and USB are on the bottom side.

preenfm2 and preenfm3 / Re: PreenFM mk2 : Continuing the discussion from the Mutable Instruments forum

I think a volume knob is very welcome function on any instrument... I really miss them on the shruthi's. It's also nice to be able to fade in/out instruments while playing and not having to go through the mixer.... And even more so using them connected to multichannel digital audiointerfaces wich often don't have a dedicated gain knob for every input and having to go to a software mixer.
What are your plans for the mkII? stereo is great! ... you should have a look at the DX7II ... i've owned one and it is veyr very fat...
things like layering 2 patches or all voices unisono with detune.
Also having played  a bit with the PreenFM i hope you can make the preenFMmkII sound a little bit more warm... The DX's are also really good at warm sounds and getting evil metalic sounds is always easy with FM. The preenFM now is especialy good at sounding evil but it;s hard getting more warm and soft sounding patches... I don't know why this is .... Maybe because it's working in integer? Are you making the preenFMmkII work with floats?

I ordered (almost) all components for the PreenFM at RS components. The only problems with it are that for a lot of the smaller stuff you have to buy a bag of say 25... but since i'm building a lot of stuf for me it doesn't really matter. I already had some stuf like the switches and buttoncaps from xoxbox.de

Cutting the case is easy of you have access to a lasercutter... mine is part wood/part plexi.
I'm getting some bolts and nuts tomorow and then i'll post some pictures.

So i build the PreenFm from bare PCB with self sourcing and everything is working. At first there was a problem with lots of noise and soft audio but it turned out it was the display shorting something on the PCB... Getting the chinese clone in was a bit tough because it is a difrent size then the normal maple...
I made a case with a lasercutter for free at the FABLAB in Utrecht.
I'll post some pictures when i get a hold of some M2 bolts...

Thanks! The flashing worked now!... I have no way to test it yet because i still have to build the PreenFM. But i think it will be ok.

For all who go for this Chinese maple copy... It has a different size!! So you will need to do some trick to be aple to plug in into the PreenFM.
