This is intriguing. I’ve been considering the ADDAC306 VC Transitions for a similar purpose. The ADDAC is 2HP smaller, has 5 channels and direction control, but is single function, while the 3PT’s knob and indicator may be more intuitive to use. I’ll be interested to find more about the modes so I can decide if they would be more helpful than 2 extra channels.

This thing is great. I'm liking all the rise of live performance tools for modular.

this does look good, at first I thought it was just a Macro controller, but if it really can output LFOs, ADSRs plus quantise and randomise, it really expands its usefulness and makes it a must have tool.
looking forward to seeing how much it's going to set me back :hihi:

People will happily build one for you 8-)

Looks really interesting, I'll be building one just for the quantizer :guinness:

I expect I will be selling them pre assembled too, when they’re ready.

Just finished building the Kit. Great module !

It's a very well documented build. First kit i got that had a physical build guide and manual included.

Had some issues with the included headers not having the right pin amount.
There where 8 pin female headers in my kit instead of the 7 pin that are needed., so i had to cut of the exces pin and almost screwed 1 up doing so.

Calibration was pretty quick and easy, just remember you need a (chromatic) tuner for it.

That info seems to be incorrect currently. I cannot find an assembled 3PT for sale either by the maker or any retailer.

Thanks. I am in no rush. :) My response was only to the citation of the claim on MG of its availability.

I am currently testing the 3PT. So far I am very satisfied. A really useful tool with a great design! I'm think about getting a second one. :mrgreen:

I got about half way through the build tonight before stopping and saving the rest for tomorrow.

The build guide is probably rhe best I've seen. I have considerable experience with audio DIY and am used to projects where you get a PCB.and BOM and then you're on your own, so it was a real breath of fresh air to see such good documentation.

You could have pulled one out, not much force needed. Also these headers do not come in 7... It might have better for Robaux to add an extra hole and not use it. I also had a 1K resistor left, there are 7 not 8.

I can't get it to go higher than 4.8-ish volts, not 5. The trimmers on the back all go to max and the three top trimmers on the from are only used to calibrate right?

Got my kit today from Exploding Shed, but have noticed that the nine tall trimpots (Alps brand) have no white line indicators on them. They're just plain black.
I presume it's not Exploding Shed's fault as they don't pack the kits, so Robaux might want to sort that out. To be fair, they could be having supply issues for parts but it's a bit annoying.

Toothpick and some white paint will sort that out ;)

Just built mine!
Very well documented kit. And nice swag!

However there seems to be some issues. I find it impossible to calibrate v/oct, mainly on output Q and R.
Also in sequencer mode if I turn the step pots fully clockwise it goes back to lowest pitch. Annyone with the same behavior?

I can't see anything obviously wrong with the build.

Edit: Oh and one or two of the leds are on when they should not be I think, Kind of out of order.

On mine, with the pots fully CW it outputs the highest pitch in Seq mode, on all 3 outputs. Fully CCW outputs the lowest pitch.
I had no issues calibrating each output, so I suspect your problem lies there.
Are all 3 trimpots at the rear of the module all turned fully CW like they should be? If they are, there must be a mistake with the build, a wrong resistor value or something.
