preenfm2 and preenfm3 / Re: preenfm2 Editor: 0.7 (osx/win win32/x64 standalone/VST)

I don't understand why would you use a virtual midi port? Ableton and the standalone app don't need to communicate with each other.

I couldn't get any sound from the synth using Ableton and the editor simultaneously. BUT.. I just realized that it works if I setup the editor to use the midi ports of my soundcard instead of the PreenFM i/o, if I disable the midi ports of my soundcard in Ableton. I couldn't get it to work the other way around though, oddly enough.

I don't know what you mean by wrapper but the problem is really within Live. You can open the PreenFM VST but the messages won't get through.
I started to work on a M4L editor for all the parameters, as you can play a bit around and manage to send NRPNs that way, but I haven't been working on it for a while and I'm so pissed at Ableton lately for all those simple issues that I'm starting to look a bit around for something else...

Yeah, I know about the NRPN issue. It's really weird that Ableton hasn't added support for it yet. But they don't really seem to listen to requests or even bugreprts, f.i. their own Push contrtoller have created stuck notes on external hardware since the release.  By wrapper I meant something like jBridge, which "aims to make it possible to run 32bit plugins in 64bit hosts, 64bit plugins in 32bit hosts, or even bridging 32bit plugins to 32bit hosts, allowing to overcome the memory limitations of a single 32bit process, in this last case."  Btw, thanks a lot for your efforts with the Max plugin so far, I really appreciate your work.

Edit: Push / pull stops working after a while. (Win 8.1 64, PreemFm2 connected via midi.)

Do you know how to:

Use the standalone app at the same time as Ableton Live for programming the synth, using a virtual midi port software
or
Use the vst in Live using some kind of wrapper

Or is the the only solution to use another VST host and rewire it to Live?

Thanks for the tip! I followed this guide, and fitted the exact same powerswitch. Since I only use usb power at the moment,  I connected the switch to the Jmp2 instead of Jmp1. Was that correct?

Thanks a lot for your help. You have no idea how worried I was about not getting the synth to work, it was like having a sick child  . Anyways, I asked a friend for help, he just happens to be a civil engineer so it took him about 1 min to fix the synth. Two of the solder joints needed more solder. One of them was at the display header, just as you expected.  And I had to replace the usb stick. Maybe you should add some info about the "squares in the display" error to the build instructions?

Right now, my only issue is that there is almost no white color on the top surface of the case, you can't read the text on top of the tacs and knobs. Is that a common problem?

I don't think fitting the ICs are hard at all if you have some idea of what you are doing. I am more of a Tim the Toolman Taylor. Btw, I really love this little synth, it sounds great and changing parameters was much easier than I expected.

preenfm2 and preenfm3 / [SOLVED] Various issues with my build (from a beginner)

« on: December 23, 2014, 07:02:21 PM »

Right now,when the FM2 starts up, the OLED display shows only squares. I haven't managed to get a good connection between the header and the display, using only the provided spacers.  Instead I have to add a pair of additional spacers, without these the display doesn't light up. This might have something to do with how I attached the low profile header. I tried to follow the instructions, but maybe the header wasn't attached correctly. I became a bit unsure about the perpendicular placement.

Also, I am not very experienced with projects like this, so I made a couple of mistakes. Somehow I was able to damage the upper pad of the second 1 M resistor, the one next to the 68 ohm resistor. After looking at the Kicad file (which didn't seem to show a very similar version of the PCB, although not identical to the one I received in my kit) I soldered the upper pin of the second resistor to the bottom pin of the other 1 M resistor. Was that correct?

Finally I think I have some issues with the ICS and the DIP sockets. The PreenF405 was almost impossible to fit into the socket, so the "socket part" connecting to PB7 was damaged, I am not sure if the connection works. Some of the legs of the other ICs became very loose when I tried to straighten them up and fit them into the sockets, so I think there are issues there as well. I actually was able to get mumbo jumbo characters as well as a frozen startup screen form times to times when I tried to make the ICs fit by pressing them down and taking them out and put them back again...

So, a lot of problems to solve. And yes, I am a beginner that made a lot of stupid mistakes. But I would be extremely thankful if you could tell me how to proceed in the troubleshooting.
