Hi Elektruck,
have you created and flashed a new "FreeRTOS project" in LPCxpresso IDE first?
This enables the flash programmer. After this you can upload the MIOS32 bootloader.
The LED should fade three times if it was uploaded correctly.
Best regards

Hi,
it would be nice to have "current operator" controllers to control
Volume, Flag, Frequency Multiplicator, Attack Rate, Decay Rate, Sustain Level, Release Rate and Waveform of the currently selected operator.
Like the "current instrument" controller on the Sid Synth.
Best regards

Hallo wiedermals,
gleiches Anliegen anderer Lösungsansatz:
könnte man nicht einfach im Sequenzer (Midirouter) eine spezielle SidDrum Destination erstellen,
die alle empfangenen current Instrument Parameter der Drum Engine (Attack, Decay...)
zum aktiven, im Sequenzner ausgewählten Drum Instrument "umroutet"?
Aber ich vermute, dass ich mir das zu einfach vorstelle...

Hi Midiboxers,
i could not figure out whats is the difference between
destination "track" and "sel. track".
Maybe someone can explain it to me?
Thanks a lot
Best regards
Marxon
EDIT:
RTFM! ;)
Now i know the difference...

Great work TK!
I love your Update-Sundays :smile:
Ok, for the case that it's really useful for other people, the enhancement is now part of the official release.That´s indeed very usefull.
It improves workflow a lot beause
i don´t need to change the mapping of my master keyboard
if i want to play another instrument.
Perfect!
Have a nice evening!

Hi,
i know this is not the best way, but you could control the filter type
with some conditional events which are depending on different encoder value ranges.
For example:
if_less_stop_on_match=Encoder:x:10 -> filter type 1
if_less_stop_on_match=Encoder:x:20 -> filter type 2
...
Best regards

Hi
Has anyone tried to make custom MIOS edits to add a few MIDI CC parameters to multimode?It's my favourite mode on the beast and would love to run it with some PW and filter effects automated.
Guess I could try playing with the script, but I'm a n00b.
yes you can do this but via nrpn
Best regards

It´s me again...
But there are good news
Finally it works now :smile:
Good output, low background noise
I simply forgot to connect audio gnd.
Slap in my face...
And the 5v issue: who cares ;)
-
Hi again :smile:
I was reheating every soldering when i noticed a missing trace on my board.
It is the 5v trace which goes to the bridge and from there to the rest of the board.
But like i said in my last post there was 5v on Ic2 Pin 1, 3, 6, 9
even without the missing trace?
So the new question is: where do the 5v come from?
-
Hi Midiboxers,
after fixing my voltage issue, i still have a output problem :(
It is very low and there is a lot of background noise:
Testtone:
I allready checked:
5V @ Ic1 Pin 1,7; Ic2 Pin 1, 3, 6, 9
+12V @ Ic3 Pin 4; Ic6 Pin 4
-12V @ Ic3 Pin 11; Ic6 Pin 11
polarity of c1, c3, c5, c7, c11 ,c16, c18, c20 ,c22, c24, c26, c31, c32, c33, c34 = checked
replaced Ic3, Ic6 = no difference
FM-Interconnection test = passed
Any suggestions what could be the fault?
May some other capaciator?
Thanks for your help
Best regards

You are the master of 1´s and 0´s :smile:The direct SR assignment (for all 8 pins) saves execution time and flash memory.As you already noticed, flash is very reduced for PIC18F452... and performance is an important topic as well.
I am just a little solder guy.
So i connect the LEDs like you think it is the best way to do.
Oder auf deutsch: du wirst schon wissen was du tust :smile:
Danke für die Info

Ja mein Englisch ist nicht das Beste...
Aber wie immer: saubere Abeit von dir.
Danke

Hi Midiboxers,
i just wondering if it is possible to change the assignment of the OP 1-4 and Instr. 1-4 LEDs?
Because there is no option in the cs_menu_io_tables...
Or is it necessary to connect them like in the FM Dout schematic?
Best regards

OK habs in meinem Gehirn korrigiert.Habs im Original File korrigiert (das uebrigens kein .pdf ist... pdf ist nur ein Ausgabeformat) -
Hi Thorsten,
tanks for your fast reply!
The actual error must be hidden somewhere else?LOL!
You are right they are also compiled.
Damn i did not noticed this :/
Sorry for wasting your time!

Hi all,
if i try to compile one of the orginal FM 1.4 pic18f452.asm
via make then i get a lot of
"Address exceeds maximum range for this processor."
make: *** [setup_pic18f452_mbfm_tk.hex] Error 1
I suspected there is may some pic18f4685 option enabled
inside the asm but they are all turned off.
The pic18f4685.asm are compiled successful.
I have installed the correct version from the toolchain:
SDCC 2.80
MYSYS 1.0.11
Gputils 0.14.3 (also tried 1.0)
The forum search did not find a working solution.
Someone know what to do?
Best regards

Hi!
Mir ist auf dem mbfm_dout_default.pdf Schaltplan ein
kleiner Fehler aufgefallen:
Der Hinweis über die Matrix Taster verweist
auf die mbfm_dout_default.pdf.
Es ist jedoch bestimmt die mbfm_din_default.pdf gemeint.
Für den Fall, dass ich richtig liege,
ist hier eine korrgierte pdf. :smile:
Mfg

Update
NG Manual - .ngr Scripts added

I am that guy...
The rotary switch in the video could be used in a digital circuitry or only analog one?I dont really understand what you mean.
You can use that switch in every circuit.
It is like you have 8 single switches but you can turn on only one simultaneously.

Hi Sauraen,
thanks for your help!
I measured current like you said: 25mA (i am using only one YMF262).
But now it gets even more confusing:
Like said before i powered the OPL module with +12V/-12V/Gnd and
+5V without its "own" GND.
After adding the additional GND line the Core boots up....?
But there is still some fault because the Testtone sounds distorted.
Best regards

So everybody with more than one Midibox is not normal? ;)
Nevertheless, thank you Thorsten!

OK i should compare the price before...:/
I'll speak to him the next time.
Thanks Freddy

Yes you are right. The "empty" project does not need to be flashed too.
Sorry for my wrong help attempt!
Thought this time i can also help somebody :(
