  1. Hi folks, I am trying to program one of my cores to store and manipulate program change messages from my Electribe. Ive written the software but then I get an error Ive never seen before when I try to 'make'. Heres a screen shot: It seems something to do with an included pic18f452.h file somewhere, but Im rather a noob at programming and dont know what Im looking for! Any help is much appreciated :ahappy: Just an update, its something to do with the code TK gave me for forwarding recieved realtime messages. Ive no doubt put the code he gave me in the wrong place or something. Heres what he gave me in another thread: ///////////////////////////////////////////////////////////////////////////// // This function is called by MIOS when a MIDI byte has been received ///////////////////////////////////////////////////////////////////////////// void MPROC_NotifyReceivedByte(unsigned char byte) __wparam { if( byte >= 0xf8 ) MIOS_MIDI_TxBufferPut(byte); } Ill keep working on it OK Im officially an idiot, I put the code TK gave me in totally the wrong place even though he made it perfectly clear. All is well!
  2. Im as confused as you nILS, basically all tests work fine, but when I plug a single MIDI source or pair of MIDI sources into the inputs, I get nothing from the output.
  3. Finally got the chance to try this out and loopback works fine! Basically it seems like every test I do points to the core being working fine, yet it wont actually do as its supposed to in the end.
  4. Thanks again nILS, Ill try your suggestion soon as I get home tonight and report back. Im sure I must be very close to getting a working merger here.
  5. Another update again. Big thanks to Mike for his quick responses to me by email. He has confirmed with me my PIC I ordered for the merger was burned with 'midimerger_pic18f_with_bootloader.hex' This would explain why MIOS Studio doesnt really see the core, but I still dont have a working merger and dont understand why. I get the correct voltages in the correct places. I just dont get it. Im totally stuck on this one :(
  6. Sorry to jump in on an old thread but Im having a similar problem, did you get a PIC burner and get it working?
  7. Another update. Mike has emailed me back and confirmed he definitely burned the bootloader onto the PIC, so now Im really confused, as when I put it into my working core I dont get the 'bootloader is up and running' message. So confused....lol
  8. OK heres an update: When I measure the VDD I get exactly 5V at all points I should except the one Ive boxed in blue: I dont know if the merger from Mikes site is supposed to have 5V at that point as the above image is just general core measurements, but Ive resoldered the joint in question and its just 0.0V. Also I took the PIC out of the merger and put it in my working core and still get 'no response from mbhp core' in MIOS Studio. So I presume this means that if the above joint is not supposed to be 5V then its because my bootloader isnt burned. If this is the case how would I go about getting it burned as I know nothing about this process. I requested a bootloader to be loaded when ordering from Mike. Thanks in advance!
  9. I requested that the bootloader be burned on the chip when I bought from Mikes store so I assume its on there. But MIOS studio doesnt recognise the core at all. Ill try swapping PICs with my working core module when I get home tonight and see what happens. Thanks for the suggestion, Ill keep you posted :)
  10. Also am I correct in thinking with the above circuit the power has to come from J2 on a core and cant come direct from the DC input jack?
  11. Hi folks. I have decided to add a midi merger to my midibox project. Currently my Midibox consists of 2 core modules that do not have LCD screens, and are used as midi filters and processors that alter the signals going between my Shruthi-1, my EMX and my ESX. I figured because they have no LCD screen I could power the merger from the same power source. So I connected up the J2 output of the core to J4 on my merger kit form Mikes Site, plugged MIDI out of my interface to MIDI in 1 on the merger, and MIDI In of my interface into the Out on the merger. Im just getting 'No response from core' message in MIOS Studio 2.2 Ive also tried using MIDI In 2 on the merger instead of In 1, but same thing. Im a bit confused in general about what voltages should read on the merger, and also the pics of the merger show all different orientations for caps. That merger pic shows the capacitor at the top left with its negative stripe pointing up towards the edge of the PCB, but then the images inside midimerger_pcb_v1.zip show the opposite. Im rather confused in general with the midimerger project
  12. Excellent! Ill try that tonight and Im sure it'l do just the job. Thanks again TK Kvetch
  13. Hi folks. I have found a purpose for the second core module in my midibox, knew Id need it at some point! It is to be used as a midi filter and processor for one of my Electribes. I have most of the functions coded and working but I cannot seem to get the midibox to forward all realtime messages recieved at the midi IN port to the midi OUT port. Whenever I run my program that looks to me like it should work, the realtime clock, start and stop messages simply wont forward to the midi out. Could anyone point me in the direction of some working code to do this, or even post a snippet of code to forward these events. Thanks in advance for any information anyone can give! Kvetch
  14. How much would you be selling for?
  15. Im also very interested if anyone knows of a good library for electronic drums one shots. Basically I want to upgrade the sounds ive loaded into my ESX as im already tired of them. Im not interested in any acoustic or realistic sounds, but purely electronic or synthesised one shot WAVs. Ive been struggling around the web to find something suitable. Basicall I dont want to sink money into a library thats something like: 2000 drum loops! hundreds of bass and synth loops! a couple folders of ones hots!...meh Thats what I seem to be finding most of and it would be a waste of my money as all I want are one shots for my ESX. Any ideas? Im willing to spend a good amount if its entirely or at least mostly one shots Im just struggling to find something suitable.
