I have SDCC 2.8.0 and gputils 0.13.6. My platform is Win32. What file should I have to build for the 18F4685? Luigi

Well, I've tried with PROCESSOR = 18f4685 but without success. I get the message: '18f4685' was not found Valid devices are: and follows a list with 39 PIC which does not include 18f4685 Any suggestions? However, MIDIBOX is great: if someone is interested I can now 1) compensate black/white keys velocity differences (a problem with my FATAR TMK88) 2) use different response curves 3) transpose the notes I'm planning to 1) add pedals (portamento On/Off, expression, start sequencer, stop sequencer, etc..) 2) add another modulation wheel 3) add splits 4) add layers 5) change the midi channel of my data 6) more... Thank you to all, Luigi

Hi to all. First of all I'd like to thank the wonderful group of MIDIBoxers that really did a wonderful work. I have two problems: 1) I have a 18F4685 but I cannot compile it (not in the Valid devices list). Actually I'm using the statement PROCESSOR = 18f452 in my makefile (mios_base_v1_0b) 2) I have a core unit with a LCD, and I don't know what pin to use (and how) for a Digital In. Are there any still available? I have a FATAR masterkeyboard TMK88. Very cheap very light but very poor MIDI implementation (no velocity curves, just MIDI chn 1, no transposition, etc...). I had problems with black and white keys (different strenght for having the same velocity codes) and I already have successfully compensated it with separate black and white velocity response curves with my MIOS_CORE unit. Now I'd like to add transpose caps as well as split, layers, etc... I'm thinking to add a DIN input to enter a special modality and then press some keys of the keyboard to input data. Most master keyboards work in this way. But where should I have to connect the switch? Are there C examples? Do I need a DIN board? Thank you in advance, Luigi

Yes, bill, that's a good start point. thank you. Luigi

Thank you, greetz, for your reply. I need to do something like the SW tools you have proposed but in HW, to avoid the need for a PC. I don't think I'll have problem to program the PIC (I'm a C/C++ programmer), but I need to know what I need: it seems that the core module is enough, but how can I program the PIC? And what PIC is the most powerful considering that I'd like to add many features such as MIDI channel changer, splitter, etc... Thank you, Luigi

Thank you very much stryd_one for your fast reply. Just a couple of more questions: once I have build the core module, what do I need to program the pic? Additional tools? I've seen that I can upload the program via sysex, but in this case will be it stored in EPROM or do I have to upload the program at every power on? Thank you in advance, Luigi

Hi, I really hope this is the right forum for posting this question: I've purchased a cheap master keyboard (Fatar TMK88) which does not allow to set different velocity responses so that when connected to some sound modules (Motif Rack ES) I have to play hard. Moreover it seems to me that the sensitivity of the black keys is different with respect to the one of the white keys. I think it is possbile to build a realtime event processor that modify the "velocity" data in order to have different responses. The question is: how can I do that? What do I need? Thank you in advance, Luigi
