"Tracks can be assigned to the outputs in the MIDI event menu. It’s also possible to route incoming MIDI events to the AOUT/gate triggers in addition (this replaces a CV interface completely). The AOUT channel and trigger routing is described in the “Special Pages” chapter of the User Manual. "
But the link is empty. It is in work i think.
And in event menu i haven’t found a parameter to route the track to gate1. There is port AOUT but it doesn’t seem to work.
I tried to select BUS1, and in the Midi Menu, i routed it into Aout chan1, and it doesn’t seem to work.
I still have my probrem with triggering it from MBSEQV4.070
I tried to connect a led beetween J5AA0 and J2Vs to try to find how i can have a 3,3v gate from the MBSEQ, but no results.
Someone can help me please? How can i be sure i send a gate trigger to J5A0?
I tried a lot of possibilities into ENENT MENU and CV configuration, but no results.
from Eric Archer:
“If you are planning on triggering the circuit from a logic signal, the easiest way is to tie ACCENT to +12V (+15V), and connect the logic signal to TRIGGER.
This schematic includes my diode-cap-resistor network. This makes trigger behavior independent of pulse width (unless the pulse is super short of course)”
" If you’d like to trigger these drum modules manually, it is easy. All you do is get an SPST momentary pushbutton and wire it between +15V and the Trigger input terminal. You need to use the diode-cap-resistor trigger circuit here. Otherwise you will get a weird sound at the moment you release the button.You can also trigger them with piezo discs and make a drum pad. get some medium or large plain piezo discs (20mm diameter for example). Wire the piezo between the Trigger terminal and GND. When you tap the piezo, it will sound the drum.Remember, the Accent terminal has to be high (+2 to +15V) for the drum to make sound. "
I’ve connected Accent to +12V , trigger to LPC17CORE J5AO and 808 ground to J2Vs
If the bass drum triggers when it is connected to 12v, then maybe the signal from j5.ao is not strong enough. You might want to experiment with a relay. Look into the midio128 page on ucapps.de. The switch S1&S2 between 12v and the 808 bass drum trigger, and vs & vi operated from j5.. Or maybe even a FET switch might work?
I’ m not an expert on this but it crossed my mind. Maybe it helps..
thanks for the answer, yes, the relay could be a solution, but in the seq, how can i send the trigger of a track to J5AO? In Event menu, with seqV4.070 i couldn’t find “gate1” . Where in this monster should we route the track signal to “gate1”??
It won’t be possible to control a 808 bass drum from a J5 output, because you will need a 1 mS trigger!
Such triggers are only available at DOUT pins, and they have to be configured in the MBSEQ_HW.V4 file:
# additional gate triggers are available on common digital output pins of the
# DOUT shift register chain - they are assigned to AOUT channel #16 (Note C-1, C#1, D-1, ...)
# define the shift registers which should be used here (each provides 8 gates)
# Note that SRs assigned to this function cannot be used as LED outputs (exclusive function)
# Allowed values: 1-16, 0 disables the function, all other values invalid and not allowed
DOUT_GATE_SR1 0
DOUT_GATE_SR2 0
DOUT_GATE_SR3 0
DOUT_GATE_SR4 0
DOUT_GATE_SR5 0
DOUT_GATE_SR6 0
DOUT_GATE_SR7 0
DOUT_GATE_SR8 0
# if set to 1, the DOUT "gates" will send 1mS pulses
# useful for analog drums
DOUT_1MS_TRIGGER 0
They will work at 5V - like on the MB808 (the second reason, why shift register outputs are used instead of 3.3V based J5 outputs)
So i chained a second Dout module to the first used for leds (it is seqV3 control surface). I connected Vs of the first shift register of the second dout (so i inderstand it is SR5) to 808 ground and D0 to 808 trig.
I’ve change hardwconfig like that: (i’ve save it and copy it into Sd card)
Allowed values: 1-16, 0 disables the function, all other values invalid and not allowed (why allowed values 1-16?)

In event menu i selected Aout port chan 16 and played note C1 to C4 without result. could you explain “allowed values 1-16”?
you would have to add following snipped into the source code (src/main.inc) after the USER_SR_Service_Finish label:
USER_SR_Service_Finish
clrf MIOS_PARAMETER1
movlw 0x00 ; first SR
call MIOS_DOUT_SRSet
movlw 0x01 ; second SR
call MIOS_DOUT_SRSet
movlw 0x02 ; third SR
call MIOS_DOUT_SRSet
;; etc... add more MIOS32_DOUT_SRSet based on the same scheme if desired
No - USER_SR_Service_Finish is called each mS after the shift register scan. By clearing the SR registers in this hook it’s ensured that the pulse will only be active for one update cycle (= 1 mS)
I won’t add new features to PIC based firmwares anymore. Programming in assembler is too cumbersome and error prone…
Hello, so i’ve got time on this project, i would like to send a trigger to TR808 kick from the first shift register (D0-Vs) of the secound DOUT module i’ve installed. i’loaded last version V4.078, with last MIOS.
When i try to edit MBSEQ_HW.V4 with mios filebrowser, mios studio says “invalid response from MIOS32 core during read operation” after that, when i Query the Core it seems Core doesn’t response in midi IN.
In my text editor photo, do i select the right choice?
When i disconnect and reconnect SD card MBSEQ respond like on photo 5. HW - is it correct?
When i put invalid parametters such as XXX on HW file, nothing happen.
On photo 6, we see asterix after AOUT * does SEQ says AOUT 16 isn’t availlable?
When i try to edit MBSEQ_HW.V4 with mios filebrowser, mios studio says “invalid response from MIOS32 core during read operation” after that, when i Query the Core it seems Core doesn’t response in midi IN.
This could be related to a USB driver issue under Windows
In your snapshot I can see that it worked once, therefore: what happens if you try it multiple times?
Could you please also check the same with the GM5 driver?
When i disconnect and reconnect SD card MBSEQ respond like on photo 5. HW - is it correct?
yes, the MBSEQ_HW.V4 file will only be loaded after power-on (or after you typed “reset” into the MIOS Terminal).
It won’t be loaded when you reconnect the SD Card. This should ensure, that somebody is able to swap a SD Card with an incompatible MBSEQ_HW.V4 file (e.g. from a different MBSEQ hardware) without overwriting the initial hardware settings.
When i put invalid parametters such as XXX on HW file, nothing happen.
yes, because you have to reset the core to load the changes.
On photo 6, we see asterix after AOUT * does SEQ says AOUT 16 isn’t availlable?
yes, because no AOUT interface has been selected in the CV configuration page.
It work well if i doesn’t try to edit HW file in mios studio.
I tried multiple times, Mios studio stop loading at different bytes.
After that, when i query the core, the midi in seems to be blocked and there is no response from core.
I have to restart Mios studio to be able to query the core and have an answer.
I will try to have my GM5 tomorow to test with it.
i haven’t AOUT interface, i just want to send a trigger from DOUT (second DOUT module Vs;D0, first shift register., so the 5th shift register of the chain.) Should i select one Aout interface in CV config page to have AOUT chan 16 availlable? If yes, witch?
For all testing moments, i always restart the core.
i can’t understand in HW file why allowed values 1-16 if each shift register provide 8 gates. why 1-16? witch value should i select for SR5? (trigger is connected to VS-D0 of the first shift register of the secound Dout.)
