Hi all,

I quickly searched if someone else detected this behaviour, but I did not find anything similar, in case please forgive.

The environment is MBHP_CORE_STM32F4, one MBHP_DIO_MATRIX connected with two 61 keys Fatar keyboards, with velocity.

Default.ngc is  

RESET_HW

LCD "%CKeyboard Test"

# reduce number of SRs for faster scan
# with 2 SRs the scan takes ca. 500 uS instead of 2.5 mS
SRIO num_sr=4

# keyboard configuration
KEYBOARD n=1   rows=8  dout_sr1=1  dout_sr2=2  din_sr1=1  din_sr2=2 \
               din_inverted=0  break_inverted=0  din_key_offset=32 \
               scan_velocity=1  scan_optimized=0  note_offset=36 \

If I play a trill (with or without scanning optimisation), more or less one time on four I lose some noteOn.
When connected with a synthesizer, it is simple to hear that sometimes one note (tipically lower of two, but I am not sure) does not play. If I am lucky, I can stop playing keeping the lower key pressed, but no sound comes from synth.

I tried to see what happens with MIOS Studio if I play (for example) e2 d#2 e2 d#2 e2 d#2 e2 d#2 (e2 d#2 4 times)

[22240.513] 90 34 7c   Chn# 1  Note On  E-2  Vel:124
[22240.606] 90 33 7d   Chn# 1  Note On  D#2  Vel:125
[22240.636] 90 34 00   Chn# 1  Note Off E-2 (optimized)
[22240.714] 90 33 00   Chn# 1  Note Off D#2 (optimized)
[22240.727] 90 34 7b   Chn# 1  Note On  E-2  Vel:123
[22240.813] 90 33 7d   Chn# 1  Note On  D#2  Vel:125
[22240.819] 90 34 00   Chn# 1  Note Off E-2 (optimized)
[22240.911] 90 33 00   Chn# 1  Note Off D#2 (optimized)
[22240.911] 90 34 7c   Chn# 1  Note On  E-2  Vel:124
[22240.999] 90 33 7d   Chn# 1  Note On  D#2  Vel:125
[22241.004] 90 34 00   Chn# 1  Note Off E-2 (optimized)
[22241.060] 90 34 66   Chn# 1  Note On  E-2  Vel:102
[22241.097] 90 33 00   Chn# 1  Note Off D#2 (optimized)
[22241.137] 90 34 00   Chn# 1  Note Off E-2 (optimized)

I tried also with Midibox_KB, only with scanning optimisation off (it seems that scan_optimized=1 directive is not processed), verified on terminal with command "kb 1", but it seems that the problem still occurs.
I tried also with couple of white keys, and it happens as well.

Anyone can suggest a solution, if there is something to modify in NGC file, or if I am disregarding something?

Thanks to all and regards,

Cristiano

Hi all,

I did some experiments, and discovered reason of this behaviour.

First of all, I enabled debug 

set kb 1 debug on

then I tried to play keyboard, while Mios Studio monitoring (excellent tool)

revealing last a#1 note (I was keeping it pressed for a while after last B1 note off) not being detected.

Debug window shows that...

[5192.339] Entry: timestamp_break=0 timestamp_make=56224

at 5191.503 I pressed the a#1 key after partially depressing, so make contact was briefly open while break contact was closed. 

No more A#1 sound while key A#1 is pressed.

Workaround #1: disable velocity 

set kb 1 break_is_make on

Workaround #2: debounce 

set kb 1 make_debounced on

And all works, more or less.

Imho when key is pressed, corresponding note should play, with low velocity, but I cannot imagine how to calculate it (perhaps double of time passed from make contact open and make contact close).

Hm... I'm using NG in keyboards for a few years now and as far as I remember I never had the issue, that notes are not being played. I enable make_debounce on my keyboards. Without that sometimes note-off is not being send (IIRC). 

As NG does not support 3-contact-keybeds at the moment it needs both contacts to be opened before sending the next note-on. Without both switches opened NG can not calculate the velocity so it's not being send. 

If "break_is_make on" works for you, it's quite clear, because break_is_make doesn't wait for both switches to be released.

Thank you FantomXR.

Both "break_is_make on" and "make_debounce on" work for me, hence I am satisfied.

I was commenting behaviour of keyboard scanning with both that directives off, because imho it could be improved.
It should behave better if sending a noteOn when detected make contact open-close without break contact opening. If not doing so, you could have a key pressed without sound.

Velocity perhaps could be calculated from a delay which value could be

if x < 2*delay_fastest

delay = ((delay_slowest - delay_fastest)/delay_fastest2) x2 - 2((delay_slowest - delay_fastest)/delay_fastest) x + delay_slowest

else 

delay = delay_slowest

where x = TimeMakeClose - TimeMakeOpen

It could be useful if you have a keyboard with heavy keys, for example.
