What does this mean? Next autumn? :thinking:
Iā€™ve sold Mangrove twice, but I think Iā€™m going to buy one again next year so Iā€™m in the same boat as you areā€¦

Pick an autumn, any autumn.

yeahā€¦ it was a hasty move, just, mid-post on MW, seriously conflicted, wasnā€™t thinking clearly, etc. iā€™ll see if I can contact them

Im on the same boat, sold my 2 mangroves (and a 3sis) to a fellow Canadian modularist and now looking up for one or two to be included in a patch Im working on :slight_smile:

We have parts arriving presently for a small batch.

long shot but did anyone in germany/berlin have to do the fuse repair on their mangrove and might have a set of these muratas lying around before I order them for way too much shipping?

#134

So a used mangrove I bought has been perennially poorly behaved. Iā€™ve struggled to trim it to match my other mangrove across more than two octaves. Iā€™ve noticed at times itā€™s been a bit unstable but today I decided to actually measure it.

Vs. The Sad Mangrove:

Does anyone know if this is something I can fix myself? Oh also, these had been on and warming up for over an hour at the point I measured them.

Updated learnings: The instability is not present when no cable is plugged in to the CV input

I wish I could help, but I do love the idea of The Sad Mangrove. It reminds me of Billy Corgan talking about one of his Strats that emits sad tonesā€¦
Seriously, does it play nicely on its own?
I am trying to patch some subtle vibrato into my Mangrove now

#136

hmmm no itā€™s more drifty than nice. I might pull it out tonight and have a look at whatā€™s going on with the pitch cv input

#137

My mangroves are starting to drift a lot more than that (30-50ct), even after they warm up. I think I have to send them to be checked.

#138

Actually I just noticed tapping the faceplate causes the unhappy one to lose itā€™s pitch. Then it settled down. Must have something loose!

I got my Mangrove yesterday and the first thing that i noticed is that how well it actually plays with a Tides v2. Something like: set tides to itā€™s standard mode. Put the end of tide input into sync and the first output of tides (the actual wave) into fm. Now the shift level knob of tides is the fm index. No need for a dedicated knob on mangrove and the waves are synced :slight_smile:

A quick question about calibration.

Iā€™ve noticed that in some settings maxing out Air kills the volume, so Iā€™m wondering if this is something to calibrate, or if itā€™s ā€œworking as intendedā€.

Settings:
Barrel: 12 oā€™clock
Formant: fully CCW
Wave/Format switch: either way actually

As I turn Air up to around 3 oā€™clock, the volume and distortion increases, but then it very quickly fades down and is completely silent at 3 oā€™clock. In looking at the scope it looks like itā€™s putting out DC, so Iā€™m thinking this may just be a matter of the Formant/Barrel ā€œwrapping aroundā€ such that the waveform is ā€œtrappedā€ up at DC rather than cycling, but wanted to check to see if this is a calibration thing or expected behavior.

#141

iirc this is a feature not a bug. when you push Air to the point where it silence the output (iā€™m assuming you are listening to the Formant out), dial Formant CW.

Cool, was just wanting to check as Iā€™ve been feeling some ā€œgremlinsā€ in the skiff recently and was wondering if this was another thing that had gone wrong.

#143

The AIR circuit is essentially a distortion, so if the oscillation is trapped near the maximum/minimum voltage, it will never leave the clipped region (and thus appear as DC). This typically only happens with Formant near the minimum, where the waveform starts retriggering more chaotically. Turning Barrel somewhat CCW will likely break out of the clamped region.

Whoa, my Mangrove just developed the same issue! Except it doesnā€™t seem to settle down. All my other analog oscillators are happy and stable so I donā€™t have cause to doubt my PSU yet. What was the issue in your case?

EDIT: Took it out for inspection and reseated the daughterboard. Tuning is approaching stable now but Iā€™ll report back when it warmed up.
