  1. Hi everyone! I have the goom synth port working on the ST32F4 Discovery board, and would love to find a way to put it into a much smaller package. Would the STM32F103C8T6 be able to load MIOS32?  I realize it only has 64K flash, so I'm just wondering if MIOS32+Goom will work on it? It's the Nano sized board that seems to have been nicknamed "blue pill". I'm sorry if this is a silly question, but I'm brand new to MIOS (which is absolutely amazing btw). I searched everywhere and couldn't find an answer to this, so I'm hoping someone may know the answer. Thanks
  2. There's this genius, ultra simple 16 voice, fully multitimbral, LPC1343 based synth called Goom concieved by Mark Owen:   It is written in are there any assembler mad men out there that could port it to the MB core?  It is open source / Mark has granted permission for it to be ported.   Making it work on the MB core would be much easier for idiots like me to assemble (no SMD) and leave some nice processor headroom for things like LFOs / noise / filtermodes to be added.   If this seems like an outrageous / idiotic question please forgive me as I'm a microcontroller know-nothing...
  3. Goom STM32F4 USB Problems

    Hi All, I hope this is considered the correct part of the forum for this. I am a novice midi to MIDI and a general tinkerer. Not much of a musician either.... I saw the Goom Synth build on the STM32F4 and thought it looked like good cheap fun. I have managed to procure the board, install MIOS32 and upload the synth "project.hex" without too much stress. I don't have a good way of playing the synth (no keyboard ATM) so long term I wanted to try using an old Motorola Xoom as a touch interface, similar to "ttfshtt" or "AVLG". Currently I have managed to connect to the tablet using the Cntrlr interface created by "Synthy" (for which I am very grateful) on both Win7 & Ubuntu Studio. All the above was done with two USB cables attached which is a bit of a pain, so I tried the PA9 to 5V trick. Although the board appears to power up, I don't get the pulsing LED LD4, and LD1 (Com) flashes instead of being solid red. By accident I have just discovered that if I plug in CN1 temporarily whilst CN5 and the jumper are in place, I can get the board to boot. Interestingly, it is more complex than just getting power on the CN1. If I plug the board into USB power block  whilst connected to my laptop on CN5, it won't boot. I needs a laptop USB to trigger the board (hope that makes sense). Has anyone experienced this and have a cure? it is a pain at the moment, and I would like to try playing with MIDI commander on either my Samsung Galaxy, or Motorola Xoom as a control interface. (currently I have managed to at least see the Goom in MIDI commander with my Galaxy and a USB OTG cable). The board I bought from Farnell is the "STM32F407G-DISC1" which seems to be an updated (but I can't tell how) version of the STM32F407. Any thoughts appreciated.  
  4. I'm sorry for cross-posting but maybe someone can help me here. I try to build the Goom synth app and getting this error message during 'make'. Linux Mint 16 Petra 64-bit. . .. ... .... ..... Creating object file for notestack.c Creating object file for mini_cpp.cpp Creating object file for freertos_heap.cpp Creating object file for wave.s sed: can't read project_build/src/wave.dd: No such file or directory make: *** [project_build/src/wave.o] Error 2 If I re-run the make, it finishes successfully but the resulting file is incomplete (smaller than the original and functional pre-built Goom project.hex from the repo). I checked the system variables (PATH's etc.) and all should be fine. (Have to check again, I'm not on the build machine now). Does anyone have an idea what could be missing? Thanks in advance!  
  5. Morpheo is a PD-Extended patch for Goom synthesizer. It's optimized to be run on dedicated Raspberry Pi 2 box with 800x480 touchscreen but works from any computer with PD-Extended. Main features are: ability to edit all Goom synth params from the control surface except Sustain which you can feed into it from your MIDI controller with Sustain switch switch between MIDI channels and edit the channel patches separately - switching the channels will store the current edits into 'channel patch' and is saved within PD file store up to 256 different sounds/patches (16 banks x 16 patches) with quick access to load and store functions morph (or interpolate if you want) dynamically between current patch and one chosen from the library with Morph fader (mapped to CC1 - ModWheel); you can exclude some parameter groups from the morphing so you avoid drastic changes in the sound (i.e. switching the OSC interaction mode) if you wish so comes with 64 patches created during the PD patch development so you can get the feel of Goom sound possibilities Check the documentation file for full features description, it's zipped in as well. Quite important is the connection, you need to feed the Goom with both, MIDI note data from your controller/sequencer and PD-Extended. If you want to morph sounds with ModWheel you also need to route your controller into PD. Routing tool are up to you, see some suggestions in the docs. All the files in 'release' folder are needed. (As of v1.0 release it's just morpheo.pd) Originally announced CC generator is not implemented yet because I faced some serious bugs which rendered it as useless. This will  be hopefully added in later releases. No git repo for now. From the time being and simplicity I'll keep the Morpheo updates here. Feel free to test it, abuse it, improve it etc. I'm looking forward to your feedback.
  6. I understand there is a build of the Goom synthesizer for the MBHP_CORE_STM32F4  that was put together a while ago by TK at the request of tffshtt.   I'm wondering if anyone would have any insight as to how I can get this onto my Nucleo-F411RE? I'm am fairly new to this sort of thing, with limited experience related to Arduino boards so far.    I've tried uploading the mios32 bootloader via the ST-LINK utility, but have not been able to connect to the Nulceo via MIOS Studio.  I am able to upload the project.hex for the compiled Goom release via ST- LINK  but as my board has no peripherals, I have no clue where to build midi input, or audio output circuits to potentially interact with the program and see if it is functioning. Your help and patience is very much appreciated, Andre
