a-112 keep sounding please..?

a-112 keep sounding please..?

2009-04-14 by falafelbiels

Hi there,

I just got an A-112 module and I noticed that it doesn't sound as an oscilator would if the gate is low. For the 1 shot mode I dont mind, but maybe for looped mode and certainly in wavetable mode I would love to have it keep going so I can add some release to a note.

Is there any clever trick to achieve this without resorting to using other modules? I am dutch and so wouldn't want to dish out for a manual gate which I would have to patch in, in order to have it perform the only function I have in mind for it. Any ideas on a mod for the module? Likely the only option is a software update to have the gate button latch I fear, but I'd like to know other peoples ideas on this. 

kind regards,
Niels

Harstikke bedankt voor de vlotte reactie! (yeah figure that out eh)

How about I just take +12 volt from the bus board, put an attenuator on it and run that to the gate in of the A-112? Am I looking for trouble here?

As I am dutch too:
I use the steady voltage from an A176 to keep the gate open when I use
it in wavetable mode.
Recently I aquired a Plan B model 36 which can be used for the same thing.
What you basically want is a steady voltage above (i believe) 5 volts.
Alternatively you could consider making a little box, fitting a 9 volt
battery with a mini jack output. That would do the same.
That's about as Dutch I can make it..

Hello Niels

What you need is an inverted trigger at note-on.

Gate----------------+
   |                 |
A165/1              |
+/-Out              |
   |                 |
A150 (or A166-AND)<-+
   |
A165/2
InvOut
   |
A112

This will send a continous gate, which will have a short break at the 
note on. This will reassure that the sampleloop starts with a new note.
In fact the start will be delayed for about 50ms, but for looping sounds 
this won't bother. If you reduce value of the timing capacitor in the 
A165/1, you may narrow this down to 1ms or less. Alternatively you may 
insert a A162 before the A150 and set its timing to minimum. Then the 
delay would be around 2ms.

All righty then, quite ingenious, but that's 2 more modules (which I don't have) used for a very basic function. In wavetable mode there is I believe no need for retriggering. Loop and 1-shot I'll perform on my MPC. I think I will try my hand on DIYing a latching manual gate.

Thank you very much for the input though...

Well I have a breadboard yes, but I'd have to get my head around this first heheh... Thank you very very much for providing this!

Hello Niels

If you are able to build circuits on breadboard pcbs then my sync2clock 
converter provides most parts required for that:

http://fa.utfs.org/diy/a100/sync2clock/din2clock.png

You need the part around the Q1, IC1, Q6 completely and IC2B. Either you 
replace it by an NAND or you use the unused gate D of IC1 as inverter 
for the signal. You may change C1 to 10nF to have a shorter pulse (= 
less delay).
