Single note Vs Continuous Oscillation

2017-02-06 by Colum Brady

Hi All,

I'm new to modular synths and got my first Doepfer system last week. I have a very basic newbie question I hope someone can clarify for me. Forgive me if I don't explain this very well but it will try to be as clear as possible.

I have A-100 Basic System 2, and so far I have a managed to get a good handle on all the modules, thanks to various youtube videos and tutorials.

The question I have is related to generating a single note (via midi keyboard or ableton) rather than continuous oscillation of the A-110. I use my midi keyboard (or ableton via USB) with the A-190-4. My understanding is the A-190-4 is hardwired via the system bus to my two A-110 oscillators, and so when I press a key on the midi keyboard the midi signal is translated to a CV signal and sent to the oscillators. This is all working great - I can play the keyboard and control pitch of the A-110 oscillators. My issue is when I stop playing on the keyboard, the last note played continues to oscillate on the A-110.

Do you know if it is possible, maybe through the use of envelope generators or a setting on the A-190, that no sound comes from the A-110 oscillators unless a key is pressed on the midi keyboard and when the key is released no sound is generated? I.e. the oscillator is only triggered when a key is pressed and when not pressed it is not generating a tone (like a hardwired synth with an integrated keyboard).

I hope this question makes sense.

Thanks in advance,

Colum

assuming that you use an Envelope Generator in your patch, first check the last segment of the EG , the Release pot: R = <50%

in case the EG is not involved in the patch, then I can't see how the gate off (end of note) is performed for every note but the last one...

Hi Colum,

Welcome to this world. 
Stopping the oscillator isn't possible. 

Use a VCA in your patch to attenuate the audio. 
Use your gate to trigger an envelope which in turn opens the VCA to let your audio pass when you send a midi note to your A190. 
There are plenty tutorials on this on YT. 

Good luck and nice noodling.

The idea is that oscillators produce sound all the time. It's the responsibility of an amplifier to attenuate the sound when it's not needed.

The typical patch is to control the amplifier with an ADSR, and you can trigger the ADSR from the MIDI module.

I hope this was enough detail for you to get it working.

I would suggest you don't have an EG or VCA in your path.
Look at the patch examples on the Doepfer site 
http://www.doepfer.de/home_e.htm
Their first patch is what you should have with the option that the CV 
and GATE are taken/to/from the bus rather than patched as shown here

Everyone else is right.  Just to elaborate a bit:

Oscillators *always* oscillate, whether you want them to or not.  Hardwired synths (the non-modular kind) hide this from you, but with the flexibility of modulars comes the responsibility of having to do all this minutia manually.  Modulars don't take anything for granted, even something as seemingly obvious as "when I'm not playing a note, I want it to quickly fade to silence."

I explain this a bit more over at https://www.youtube.com/watch?v=VnoWQeEOSqo if you find video examples more intuitive than reading about it.
