preenfm2 and preenfm3 / Re: Not recognized as a USB device
« on: March 15, 2014, 07:40:43 PM »
Hi Xavier -

I've tried it on Mac and on Windows, neither works.  The device is not recognized by the OS.  Here is a dump from the logger in USBProber on my Mac:

preenfm2 and preenfm3 / Not recognized as a USB device

Hi there -

I've had my PreenFM2 for some time now and it's been great.  The one thing that it has never done is to be recognized as a device via USB.  I have to open the back to get the stick out and put the new firmware on that. I've debugged it a little and I do have a good connection between the twin pins on the board and the USB processor.

Any ideas where I could look to fix this?

Thanks,

Mike

preenfm2 and preenfm3 / Question about USB
« on: December 29, 2013, 09:51:32 PM »
Hi Xavier -

I have a question about USB. When I plug the FM2 into my iMac it id not recognized as a MIDI device.  Should it be? It's also not recognized on my PC.

One more: should the USB stick be visible to the Mac or PC as a drive? It would be convenient to have it work this way so that I don't have to partially dissasemble the case to get the USB stick out.

Thanks!

Mike

>> How does it compares at the low notes mantaining whole sound?

Not sure exactly what you mean, but the FM2 has a terrific bass response.

>> How about other sounds like some strings, octilate preset or bass 2?

I'll put some more up.  Note that not every DX7 preset translates exactly...

>>Do you think are there power in the low frequencies?

Yes!

>>Nice....   :D

Thanks, Xavier! You've built a cool machine :)

Newly built and fully working (now!) PreenFM2 playing a DX7 patch: TubBells.  Note that I have the overclocked 0.9J software flashed.

preenfm2 and preenfm3 / Re: New Build, buttons do not work
« on: December 11, 2013, 09:42:47 PM »
:))) Success! I redid the solder joints on the resistor network and the buttons all now work.  The clue (apart from Xavier's help) was that the button would *sometimes* show 3.3v if I pressed the probe on the meter the right way. That meant a bad joint.  It was also happening on the third button.  All fixed, will reassemble and play!

Thanks all who helped!

Mike

I *thought* I checked it correctly and it did bounce as you described, but when I just double checked the non-pressed voltage is essentially zero. When pressed it does go to ground (all zeroes on the meter)

Thanks for the responses :) chips are good, solder is good (I redid the points pointed out by Xavier), button voltages are correct when pressed. Resistor networks are in correctly. I think Xavier is right about it being the Eng button: when I start up by pressing the Op button (for firmware update) it goes to the correct screen (but does not respond then to any buttons).  By the way, I do not get the start up notes playing either.  Here is a link to a better picture: http://www.pantanosoftware.com/music/PreenFM2BuildTop.png

preenfm2 and preenfm3 / [Fixed] New Build, buttons do not work
« on: December 11, 2013, 01:42:01 AM »
Hi There -

Just finished my FM2 but have issues. NONE of the buttons work and the encoders just cycle between Engine, Modulation, and Mixer.  The volume knob works and I get sound when I send MIDI over DIN.  My mac does not see the device over USB.

I've attached a picture of my build.

Any thoughts?

Mike
