"Pop" noise with init values
« on: October 16, 2013, 11:05:47 pm »
Hello!

New user over here  ;D  !

When Minibrute is set to init values (all envelopes down, all waveforms down etc... except volume, set to 75%) and I press any note from the keyboard or external midi controller, I hear a POP sound. When I set 20% the AMP attack the pop seems to be delayed (obviusly, with attack) but not dissapear.  It seems to be affected by Fast/Slow envelope speed, making the noise more hi or low on freq. Also, amp sustain hi/low values seems to affect the noise.

It is an amplification (normal) issue?
Is my unit defective?

Thanks a lot and sorry for my english. :-[

Ps: attached image with the synth settings and noise audio files.

That's normal for analog envelopes.

Even with the ADSR all the way down, the amp is still opening and closing. It's just that each envelope stage is set to the minimum value, the fastest time. That super-quick open and close of the amp produces a little click or pop, even when there's no oscillators mixed in.

What the click proves is that the MiniBrute has nice envelopes, great for sharp attacks.

T3k, thanks a lot, that's very reassuring  ;D

But, I didn't understand that still making click's or pops "delayed" when hold one key and attack (amp) is at 50%-75%  ???  . Also, this sound reproduces when oscillator is on (Checked in spectrum analyzer)

Hmm

I'm also a new user and ive noticed that im getting a clicking when pressing a key  too.
it's from the lfo section. I have to ad some attack in the amp section to get rid of the click? That's not right is it?
You can hear it more in hp filter mode.
I am new to this synth and it's my first analogue synth but i think something is not right?

any ideas?
Thanks

It's the same case, no relation with LFO (Only LFO functionality), it's about Amp envelope. Ad attack is not a Workaround.  Test yourself: up attack fader about 10% and hold one key until the amp led turns off. Now, do the same action with 20%, 40% and above.............POP!!!  ;D

Seems that Minibrute has a lot of character  :P
