Pilot Run MRCC Units Have Arrived
26 days ago – Thu, Feb 04, 2021 at 06:42:36 AM

Greetings wonderful backers,

Yesterday we received the first samples from the MRCC pilot run. If you are not familiar with the term "pilot run", it means a practice production run to work out the kinks before committing to the entire production run. So how did it go? Splendidly! Everything is working as expected, with the changes from the prior samples checked out and verified to be working to spec!

Production MRCC!

The new OLED acrylic screen cover looks and works great. The new black interior USB ports are an improvement,  and the connectors are all aligned with the holes now. Silkscreen printing looks better aligned now too.

There are a couple fine adjustments to make, as we found three mechanical issues:

The first is, the holes for the light pipes are too small by a fraction of a MM. We expected this could be the case due to the hole size changing in acid-wash and anodizing, but we estimated too small. We were able to take off 0.168MM to make the light pipes fit perfectly in the new samples, so we know what to do.

The second problem is that we are not really pleased with the finish of the enclosures. It's more "matt black" this time, as desired to reduce reflections, but the aluminum brushing is inconsistent. It may seem minor, but some people (like us) would find it unacceptable. Our manufacturing rep will work with the metal fabricator to get it right before we make your MRCC after Lunar New Year.

Lastly, there were some potentially skin snagging barbs on a couple of corners of the endcaps. We don't accept bleeding on the MRCC. Needs more buffing.

New Nearly Flush Rack Mounts

Hey, what's that green button next to the MRCC logo you may ask? That's the Standby button. Hold it for a couple of seconds to put MRCC into Standby mode, which turns off the OLED display, LEDs, USB hub power (configurable) and stops taking input, without having to power off the MRCC with the power switch. Short press the green button again and it brings you back to where you were before standby. 

Next Steps

We are sending some pilot units to select beta testers which will help to inform us of any bugs, usability issues and topics to cover in the manual. We'll publish an early draft of the manual on our MRCC forum soon, once we've done some editing to clean it up. Be sure to join our forums at:  https://conductivelabs.com/forum 

If you have any trouble joining, send us a message via the contact page on conductivelabs.com.

Besides working the beta and addressing any issues, we need to complete the box packaging design, get the regulatory compliance test results, and spin up our warehouse fulfillment company to be ready to ship them to you! Pretty exciting to finally be this close!

Between now and March, we will see if we can't make a couple more demonstration videos. Subscribe to our YouTube channel here: Subscribe

All the best,

The New MRCC Samples Are In
about 1 month ago – Mon, Jan 25, 2021 at 04:09:39 AM

The new samples of assembled MRCC circuit boards arrived at our manufacturing rep tonight. We spent some quality time testing over Zoom, and.... they are working great! They should receive the new enclosure samples tomorrow, but we are moving ahead with the pilot run. Exciting!

Production Candidate MRCC Sample

It's a tight schedule, as China is implementing travel restrictions so people are leaving earlier than normal to go home for the Chinese New Year holiday, including our enclosure manufacturer! Fortunately, our manufacturing rep talked them into making the pilot parts before they go. They are not making the Remote enclosures though, but we can live without those until they get back from holiday. In the meantime, we'll make a temporary enclosure for testing.

What else is new? We tested the Remote 7 with a 50 foot long Ethernet cable. According to the MIDI specification 50 feet is the maximum length of a MIDI cable, so that's as long as we are going to support.

That's all we wanted to share for now. We'll be back with another update once we've received assembled MRCC samples in Oregon. We expect those to arrive in the 2nd week of February. We are still shooting for shipping Kickstarter perks in middle of March, and pre-orders around end of March.

Wishing good health to all,

Darryl and Steve 

Parts are on their way for PCBA
about 2 months ago – Fri, Jan 15, 2021 at 06:45:34 PM

Hello backers, just a quick update to note a milestone on the way to production. We've got all of the parts for 1000 MRCCs heading to the PCBA (Printed Circuit Board Assembly) vendor. Exciting despite the dingy view from inside the delivery truck :-)

Parts to make 1000 MRCCs in the delivery truck

We are on track to get the new samples (5) and pilot units (45) completed before Chinese New Year.

Here are some not so great pictures of the new circuit boards:

The new MRCC Main board. We made them matt black to reduce light scatter to the light pipes:

We will panelize the mezzanine board for less PCB waste before we go to production...

Our friend and award-winning industrial designer Nick Oakley came up with a nice graphic design for the MRCC Remote 7. When the Backerkit survey arrives, you will have the opportunity to order this for delivery with MRCC.

Remote 7 MIDI Extender for MRCC

The "Ethernet" port is not Ethernet, but it uses an Ethernet cable to cleanly extend ports from MRCC to where you need them in your studio. It requires an Ethernet cable with shielded connectors that are connected to each other via the ground wire in the cable. We've tested up to 35 feet so far, but we have a 50 foot cable on the way. When we ship MRCC, these ports will be replicas of MRCC outputs 1 through 5. However, we will attempt to turn these into five separately routable additional ports in a future firmware update. It's already wired for that.

That's it for now, we'll be back with another update when we've got the new samples.

All the best,

Steve and Darryl

Now taking Pre-Orders for MRCC
3 months ago – Tue, Dec 08, 2020 at 10:29:14 PM

Just a quick note to say, that due to (very) popular demand, we've opened an MRCC Pre-Order store on Backerkit. We're estimating a ship date for pre-orders starting late March. 

MRCC Pre-Orders

Of course there will be no units sent for pre-orders before we fulfill our Kickstarter obligations. We are still aggressively aiming to beat Chinese New Year; they start vacation on February 5th. 

As Kickstarter backers, you will have the opportunity to select add-ons to MRCC when the survey is sent out, shortly before shipping. Please don't order accessories on the pre-order site, wait for the survey. Also note, your Perk comes with Rack Ears included.

Our manufacturing rep has yet to ship us the new enclosure samples, they rightly prioritized getting parts ordered before running around to make the samples. We expect they will be on the way this week. They are currently working to finish them and shared some pics.

On the software front, Steve is working the burn down list which is rapidly shrinking. The biggest item left on the list is saving preset data for non-routing items, such as for the arpeggiators, velocity maps, and keyboard splits. Steve estimates he'll be ready for the pilot build with at least beta quality, just in time to do a round of testing.

The new circuit board designs will be complete this week. We've been running into more parts shortages and had to replace a few more components. Nothing risky fortunately. 

While we wait for parts to arrive, we'll be completing the OLED screen protector design, and dialing in the enclosure. We've already noticed some of the models don't match the actual part size so we need to adjust some hole positions and sizes. Minor issues.

That's all for now. Once we have the finished enclosure samples we will share some pics of those.

All the best,

Steve and Darryl
