Has anyone used an Electra One with the MRCC? I'm debating buying an Electra so I'd like to know  what the deal is. Thanks.

  Help: Midi mapping to 8 channels
Posted by: opabert - 07-02-2022, 07:39 AM - Forum: Hardware MIDI Connectivity - Replies (3)

Hello to you all, 
my name Bert age 70++  English not my native language.  I send email to support but not reply on that. Have very large setup with  keybords,  2 sequencers and in total 10x  differ mono synth.

For sometime i use retrokits midi router for my MIDI routing and this week buy MRCC because of the connectivity, cable management and the ON/OFF buttons per MID channel
For days try figger out how routing my gear who not doing what i able do with my retrokits.
MRCC MID DIN INPUT -1   have a keybord / Sequencer and all my SYNT use differ midi channel input like this:
SYNT-1 input set to MID CH-1
SYNT-2 input set to MID CH-2
SYNT-3 input set to MID CH-3
In channel mapping, it seem not possible mapping the MID keybord or sequencer channel-1  to  8 synt differ MID channels out. Only, work when all 8 synth manual set to same MID channel in this case MID channel 1.
The channel mapping have no "OUT-ALL")

in short terms,
Possible to connect my MIDI keybord or sequencer run over input channel-1 MRCC MID mapping to output 8 differ MID channels?

Thank you

Hi all,

I tried to look for posts about it but I didn't find anything. Is it possible to use 4 software instruments with the ndlr? How should I set up the instrument? Once all the USB ports have been assigned, nothing is heard. Advice?  what am I doing wrong?

  Open Source Firmware?
Posted by: benstat - 06-24-2022, 12:11 AM - Forum: MRCC Feature Requests - No Replies

Hi all,

Having been a software developer for more years than I care to mention, I find myself wanting to tweak the MRCC firmware (and NDLR too), and potentially submit bug fixes and improvements.

I realize it's a bit of an unusual, niche request, but there are a lot of us software devs around, and we just can't help ourselves sometimes! It's also something that other, small manufacturers have done in the past (eg. Electra One, Norns, etc).

Not much to lose really, unless of course there are trade secrets buried in the code. Wouldn't take long to share the source via GitHub, and then approve/decline push requests from outsiders once in a while.

Just something to consider that could potentially benefit everybody.

Keep up the good work!

Many thanks,

  I love the MRCC
Posted by: Jeremiah - 06-20-2022, 12:32 PM - Forum: General Support - Replies (1)

Hello, I'm just a home hobbyist, but of long-standing going way back to cassette-based 4-track recording. DAWs like Voyetra Digital Orchestrator on 5 inch floppies and then 3 inch floppies. Now with Ableton Live.

Only people of a certain age will know what that refers to.

I've been fortunate to recently update with some nice hardware synths.

And your MRCC MIDI Router Control Center which is like a dream come true.

To be sure, I'm only doing the most basic stuff, but it works great!

  NDLR Cntl and KB Trans
Posted by: racecube - 06-20-2022, 04:49 AM - Forum: Advanced Features - Replies (1)

I really don´t understand how these settings work!

In another Thread someone explained it with a Arturia Keystep: Both (NDLR Cntl and KB Trans) set on the same Midi Ch and you can switch your synths to every scale you like but the NDLR will change its chords on the white keys of C major. That is how I understand it, but it does not work: If I put both to 16 I can´t change any chord via my keyboard, If I put NDLR Cntl to 15 and KB Trans to 16, I can change NDLR chords with my keyboard on CH 15.

In the above thread there was a link to YT video that should clear it up - it was no help, just a pretty NDLR session on a Keystep and a Blofeld. A tutorial video would help a lot !!

Another thing is the completely undocumented feature under SHIFT MENU ENC 2: Rotation Algorithm, it was asked for help in another thread a while ago and nothing happened. Users seem still trying to sort it out but are left in a foggy forest. (The KB Trans MIDI CH is mentioned on that menu point as well by the way)

The NDLR beta firmware 1.1.079 is meanwhile 3 years old and still a beta, this tells a lot I think, are you guys only working on the MRCC any more? (..or on new forum skins ;-)

I had great hardware support a while ago and I think the NDLR is still an awesome device, but I am a bit disappointed.

I won´t ask for features or improvements any longer, but: A VIDEO ABOUT NDLR Cntl and KB Trans WOULD REALLY BE APPRECIATED !

  Is there a way to filter clock out or Remote Outs
Posted by: The Puppeteer - 06-19-2022, 09:20 PM - Forum: MRCC Advanced Configuration - Replies (1)

I have a Kawai R100 connected up to Remote Out 3, and I want to stop clock being sent to it.  Is there a way to do this.  I can't find the Remote7 outputs on the Output Filters. My Remote7 is set up as Remote 1-5 on the settings page.

  Prog change 000 or 001?
Posted by: Stratblue - 06-18-2022, 07:46 AM - Forum: MRCC Feature Requests - No Replies


Some of my kit starts its program numbering at 0, the rest starts at 1 it would be cool if there was some sort of on/off transform function to compensate for this so that when I send PC 001 from the sequencer it loads PC 001 in everything.

  MRCC Pre-purchase Questions
Posted by: ekkomouse - 06-16-2022, 06:15 AM - Forum: Hardware MIDI Connectivity - Replies (5)

  1. Does the mrcc have the ability to remap poly aftertouch to channel pressure and vice versa? trying to fix an issue with a synth reading only one or the other from various midi controllers.
  2. Will it pass through, besides sending the MIDI data, is also transmitting - CDC (serial) and Raw HID. Related to use with Polyend Play see link: https://help.polyend.com/431975-My-iConnectivity-MIDI-USB-hub-is-not-recognising-my-Polyend-instrument-why
  3. When interfacing with the computer, am I able to name the inputs and outputs on the MRCC device and the names will show up in audio/midi setup on Mac, therefore being passed onto DAW's? 
  4. Am I able to setup an RTP Midi network? Not so important but coming from MioXL where I have one device working through RTP currently
  5. Does the device allow for connection to iOS/iPad midi devices? I plan to add an iPad on next update, not as familiar with how these will interface
  6. On virtual inputs on host USB ports, does that mean we can plug a USB hub for access to the 4 inputs? Read FAQ and it says not really, I'm trying to understand how the 4 virtual inputs per host port work, maybe get an example use case?
  7. Can the MRCC receive midi clock from a connected device then translate or sync its internal clock to send the same clock out of its cv clock output?
  8. If I need to expand with a second unit, would I configure advanced functions from one screen or from both separately?
  9. Will the virtual midi ports seen by a Mac audio/midi setup be available to route software and be viewed as additional input/outputs on the device for various saved routings? Example currently is I have to use midi input/output in settings on Komplete kontrol keyboard software to translate incoming MPE from a roli seaboard to get it to send the Roli to other external synths, currently routed through a MidXL, the Komplete kontrol is receiving from itself, the roli and a polyend play to route to other devices without opening a DAW.
    I know its a lot of questions, if anyone can answer one or two, I appreciate everyone's time.  Probably ordering one anyway to test but would be nice to know these in advance.
  10. Can I use a basic trs mini cable to transmit trs midi from one device to trs midi on the MRCC? Any special cable requirements for type a vs b? Use case is a launchpad type controller with trs output going direct to trs input without those trs to midi converter cables.
