measurement without oscilloscope for the first wave ?

Postby Chairapta » Tue Jun 14, 2016 5:28 pm

Hello
How can I make a precise measurement of the waveform without oscilloscope ?
I thought my sensors connect directly to my sound card and use cubase .

Here's what I get:
1-4 : moderate strokes
5 to 8: weak moves
9-12 : When I drop the baton from a height of 15 cm, with the rebound.

The blue area is 1 ms .

Are these good signals?

Looks alright provided the signal levels follow hits strength closely.

when I listen in cubase it really detects the shot with good sensitivity ,
I will try to find the right setting , it's for my snare .
my minscan not be well chosen.

Step 1 : I assign a "note" corresponding to the center in superior drummer (A0) and a "note" for the rimshot (E1).
Step 2 : I gradually increased the threshold to remove false hits. ( 40 head and 42 to the rim).
Step 3 : I check auto lvl and I hit hard 10 times the snare.
I see a midi output to notes 33 and 40 while I did not hit on the head.
Step 4 : I remove self lvl and I fixed highlvl 470.
Step 5 : I am 10 sidestick for trimming the HighLevel Rim.
Step 6 : I remove auto lvl and I fixed highlvl 300.
Step 7 : ...


After I 'm confused,... By the signals measured in cubase , i try to set the minscan , dynlvl and timelvl , but I can not get a good result.

You have to set it to "dual or 3way yamaha" instead of "single piezo" at the bottom of the 'head' menu.
If it ain't broken... fix it until it is.
