Help, Gligli firmware upgrade #98

Open syntomik opened 7 years ago

syntomik commented 7 years ago

Please help, pressing "from tape" + "to tape" the "U" appears on the display but when I send the syx file from midiox nothing happens. The syx file is sending but the P600 always shows "U". I'm using a db15-midi cable from the sound card to midi on the P600 ( I don't have a USB-midi cable). Could this be a setting issue in midiox or some other problem? Not sure where to go from here, any help appreciated. thx

Have you verified the sound card/midi cable can succesfully send any sysex data to any of your other synths?

Naturally, that's the first thing I tried. I successfully transmitted sysex to Siel DK600 using the same method. So, I'm wondering if P600 is waiting for data on the midi in or not? anything else I can check?

update: I went out to purchase a USB-Midi interface, installed it, drivers loaded. Still nothing from the P600. Actually, most of the time it stays on "U" but sometimes I get "E". I configured the timing buffers to 250ms like the manual says but still nothing. Still no problems sending sysex to my Siel. Does anyone know what's going on, why I can't upgrade the firmware? Am I overlooking something or setting?
I tried both p600firmware and p600fw_stable_2.0, no difference Any suggestions, anyone?

Do you have a genuine Teensy board and not a China clone from eBay? Does your current P600 firmware respond to MIDI CC and NOTE on/off correctly? What is your current firmware version and why do you need/want to flash it? Can you succesfully dump a sysex to MIDIOX: "Miscellaneous Settings function “6” will send a SysEx dump of all presets on MIDI out. Use your favourite SysEx utility to store it." http://www.midiox.com/cgi-bin/yabb/YaBB.pl?board=query;action=display;num=1424865245 HTH

Yes, I have a genuine teensy with orange led. I'm just following the manual so I flashed the teensy with the hex file, it booted , got the scrolling message and went thru its calibration. Next step, upgrade the firmware, this is where I'm/teensy is stuck. P600 eprom is six-0-8, I can't seem to upgrade the teensy firmware? I'm not dumping to PC

So, re-installing the Z80 and checking midi in/out data with midiox works flawlessly without issues, midi in/out connections are good from p600 to pc, even re-loaded the factory patches without problems. So my problem lies within the teensy ++ 2.0 I will start over with the connections and re-flash the teensy and go from there. thank you all for your suggestions!

I know you successfully sent sysex to your Siel, but I'm gonna say this anyways: is the "pass sysex" option in midiox enabled? (Options -> Pass Sysex). I missed this one and was struggling to understand why it wasn't working.
