Snare release

Postby Ken Forgettable » Sat May 02, 2009 12:41 pm

Suggestions for implementing a 'snare release' using the existing hardware please.

Got in the grove last night and turned off the snares.
It was quite a psychological shock when nothing happened...

The therapist said "toggling the snare midi note may or may not work" 8-)

Yeah, you could reserve the midi note adjecent to your snareH note, map it for snare w/o seiding and and use the Up/Down keys on the MD to toggle.

You could also wire an on/off switch to the key up/down and place it on your snare. Perhaps even glue a picture off a real snare switch to it and have Dave Weckl standing next to it and go: *click*
Erm.. m'kay, got carried away...

I've wonder how long the delay for change drummap is, because I'd like to use a switch to change, say all pads and cymbals to percussion in a click.

This is already possible using 'Quick Access' like this.

Yup, I just haven't found the time to make the physical switch and I'm still using the 'YES' option for quicker configuration.

Are you looking for a scaleble solution or just on/off?

a scaleble solution

Hi,
“Let go of your pickle”.

Just considering the snare release as a toggle for the moment I assume your 'scalable' comment is referring to the fact that the global patch change would a kludge for this feature as two snares with this option would require four patches to be set up ie XX, OX, XO, OO.

What :!:

If this is the supposition then I agree that's what a patch is for; but I'm suggesting that a drum brain should have this feature for the snare built in - that's why I got the shock, the hi-hat has special hardware to enable it's functionality but it appears that nobody has ever taken into account the dual nature of a snare drum at the design stage.

“Let go of your pickle”.

A real snare has a mechanism to control the snare tension and also a lever to enable or disable the action. Given that the current trend is for sample based triggering rather than synthesis, the e-drum analogy for the snare mechanism using the existing hardware means using two sample sets; one with snare on - note A, one with snare off - note B.

Being a complete sociopath I've nursed the idea a while and it seems to me I could have asked: is it possible to have the entire snare mechanism as a controller. Imagine then a snare tensioner as a control message managing the velocity levels between note A and note B – but then this looks like a problem for the software sampler; even if the brain were to produce such data.

Forget it: about as likely as Mitch Mitchell or Keith Moon using a 12” snare.

Anyway. Do the two existing sensors have an unused state that can unambiguously be considered as the note toggle?

PS. I'm not holding my pickle.

The snare mechanism is rotational. Perhaps a pot and few components (if Weckl is unavailable) could translate the physical mechanisme to Input A max-min -> Input B min-max
But as you suggest, it'll probably sound fake without the sampler make-over.


PS. I had to look up pickle in the dictionary ;)

PPS. Come to think of it, acustic snare drums is in fact a tom-like drum with the snare overlayed. You should be able to produce naturel transition only by turning snare gradually off. Input A max -> Input B max-min

This would be a nice feature using sound synthesis, but I don't see a practicle solution with sample based software like Battery or BDF - you'd need to square the number of samples required for very little return. It's a similar issue BDF has with positional sensing where they elected to provide just two zones (number of samples x 2).

Snare release is less of a problem as megadrum already handles articulations like rim shot etc.

So what about this inelegant solution:
Have a push-to-make button on the shell which grounds the central piezo and hit the drum hard.
The brain sees the rim piezo has registered a strong hit but there is zero crosstalk to the central piezo (it's effectively been removed) - a clue to toggle midi note.

Or this:
Have a push-to-make button on the shell which puts both sensors in series and hit the drum very softly. The brain sees the central piezo has registered a very soft hit but it seems to have generated 100% crosstalk to the rim sensor - a clue to toggle midi note.

Maybe do it like a Yamaha 3 zone cymbal? I know this isn't exactly the same, but put the resistor in series with the head piezo, then for the release, just short it around the resistor.

How about having the SnareH optional connected to two inputs and have an switch on the snare decide wether it's input A or input B getting the signal.
