Filter ENV Amt. potentiometer issue.
« on: July 11, 2012, 09:43:04 am »
I am curious if Arturia put the wrong resistance value potentiometer on the Filter ENV Amt? It seems at about half way to + the envelope is at maximum. Also if you compare the patch sheet, to match the sound of the Funk Bass patch from musictrackjp's video on YouTube (After around 17:15 at http://www.youtube.com/watch?v=VvQbPC_I4XM), I have to set the ENV Amt about half way down from the setting that's marked on the Funk Bass patch sheet on mine. The ENV Amt. set past about the 5th out of 9 mark from the center, towards the + positive envelope begins to sound funny. The signal level starts to cut out a bit, or perhaps sound overloaded on my Minibrute. Anyone else with a Minibrute experience this, or care to check on this? The envelope is not useful on mine past that half way point. And the majority of useful positions are in a very small area near the center of the pot. Anyone else with a Minibrute experience this as well, or care to verify? Perhaps I'm the only one experiencing this? Thanks.

I'm curious if this could be calibrated through the small screwdriver potentiometers on the rear panel of the synth? They're unlabeled, and I can't find any information about them in the manual.

I think those or at least some are to calibrate the CV in/outs since I've seen Nick (from SonicState) mention something about needing to calibrate CVs to tune it perfectly to his Eurorack.

Have you sent a Support request about this issue?

It's unfortunate that you turned yourself into an annoying troll with nothing useful to add to what you already stated.

Relax while listening to this, Filip ;)

Anyway, funnily enough, you're mentioning something that's true. There's a Minibrute update ;D but I would be extremely surprised if it included a firmware fix for that part of the synth (the analog knobs) ...that would be cool, but if true, then there would also be CC input for them, which there isn't since those are purely analog, AFAIK.

In the sos review,he did mention that some of the modulation depths were a little too high,could this be what he meant? (i know that one was unfinished though)

My ENV amount knob seems to work fine. There is some dead space at the end of the knobs for most parameters. But other than that everything works as it should.

Try setting filter keyboard tracking to 0%, Cutoff to minimum and LP filter mode. Put filter envelope to full sustain and play with the filter envelope amount knob. I get changes almost to the maximum setting.

Would you check the 'Funk Bass' patch sheet that came with the Minibrute and compare it to the video review in my first post as a comparison? Thanks.

My filter was pretty much wide open, until I set the Filter Env. Amount down from 3 o'clock to between 1-2 o'clock.

Here is an audio clip of what my Minibrute sounds like with the Funk
Bass preset sheet. At first, the Filter Env. Amount it is set to 3
o'clock as-is on the sheet, then the second part is when I turn it down
from what is on the preset sheet, between 2 and 1 o'clock. I believe the
patch is meant to sound a bit more like the second part?

2 audio segments. First part as patch sheet. Second part with adjusted
Filter ENV Amt:

Here's what the patch sounds like on mine: http://www.youtube.com/watch?v=pAjth-UM18g

The only times I had issues with the filter were when I forgot that the mod wheel was set to cutoff (demonstrated the second time the riff is played).

My Funk Bass patch sounds similar to the one konspirativ posted.

Audesi, did you try the stuff I suggested. Do you have anything connected to the VCF input? The mod wheel isn't active on filter cutoff in this patch, so I think that isn't it. What does the Filter Env amount do when you go negative. Does it bottom out at position 9?

I would think that one notch of the scale is just the analog differences in parts. Every MiniBrute will sound a little different as every MiniMoog did.

Here is what mine is doing, and you can see the knob positions. All other controls are set as marked on the patch sheet. I'm moving the mod wheel to show that it's set to Vibrato and not cutoff:
